I made a method « numberMatch » that push a gif, that is stored in a variable, in a tab on click. The method works well, but when i call the tab in the template instead of the gif it’s the path of the gif that shows as a string value.
Can someone tell me how to make the gif appear properly on the page instead?
The div that show the image in the tab in the template is this one:
<div>{{this.gifTab}}</div>
<script>
export default {
name:'Body',
data() {
return {
luckyNumber:'',
randomNumber:'',
number: 0,
gifCharles:require("../assets/jpg/isolation-charles.png"),
gifTab:[],
scoresTab:[],
total:0,
}
},
methods: {
RandomNumbGenerator(){
this.randomNumber = Math.floor(Math.random()*11);
return this.randomNumber
},
InputValue(){
this.luckyNumber = document.getElementById("input_lucky_numb").value;
},
NumberMatch(){
if(this.randomNumber == this.luckyNumber){
var tabGif = this.gifTab.push(this.gifCharles)
return tabGif
}
}
},
};
</script>
You need to add an image element.
Replace
{{this.gifTab}}
with
<img :src="gifTab"/>

Let's say I need to add an element to the navbar when the user have scrolled past the header of the site. How can I do something like this in React without using jQuery?
You can do some thing like this: (this function was copied from my own react-sticky-dynamic-header that I created before: https://github.com/thinhvo0108/react-sticky-dynamic-header )
componentDidMount() {
var h1 = parseInt(this.refs.header.offsetHeight);
window.addEventListener('scroll', this._calcScroll.bind(this, h1));
}
componentWillUnmount() {
window.removeEventListener('scroll', this._calcScroll)
}
_calcScroll(h1) {
var _window = window;
var heightDiff = parseInt(h1);
var scrollPos = _window.scrollY;
if (scrollPos > heightDiff) {
// here this means user has scrolled past your header,
// you may rerender by setting State or do whatever
this.setState({
//stateKey: stateValue,
});
} else {
// here the user has scrolled back to header's territory,
// it's optional here for you to remove the element on navbar as stated in the question or not
this.setState({
//stateKey: stateValue,
});
}
}
render() {
return (
<div ref="header">YOUR HEADER HERE</div>
);
}
For a smooth animation when your element added or removed from the navbar, you can just add this into the element's CSS style:
#your-element{
transition: opacity 0.3s ease-in;
}
You can try to install my library to see if it can extend your needs:

Feel free to post here some errors if any, thanks
In my website, in order to load diferent pages (to be multipage website) I have a main panel that has the id 'content-panel'.
When I want to load a diferent page I have a javascript function that is called 'loadPage' that loads the page (panel) that I want to the 'content-panel'.
But the page that I want to load has to have this code:
Ext.require(['*']);
Ext.onReady(function() {
...
var panel = Ext.Cmp('content-panel');
panel.add(loginPanel);
panel.layout.setActiveItem(loginPanel);
panel.doLayout();
panel.setLoading(false);
});
In this case it is loading the page/panel that is loginPanel, that is defined inside Ext.onReady
For me this is fine, I don't know of any other way of my website being multi-page.
But everytime that I want to go to a page it loads that page to the 'content-panel', even if it already been loaded before. I want a way to only add the page to 'content-panel' if it is not inside 'content-panel' items.
UPDATE:
Here is the loadPage
function swap(parent, replacement, url) {
var alpha = document.querySelector(parent);
var target = alpha.childNodes[0];
var omega = document.createElement(replacement);
omega.src = url;
omega.type = 'text/javascript';
alpha.replaceChild(omega, target);
}
function loadPage(panel, toPanel) {
toPanel.setLoading(true);
swap('head', 'script', panel);
}
it is used like this: loadPage('Ctl_base/view_admin/mainPage', Ext.getCmp('panel'));
I'm using CodeIgniter with ExtJS.
What I have already tried:
I want to do panel.add(loginPanel) only if the loginPanel doesn't exist.
I have tried:
if(panel.getComponent(loginScreen) == undefined) { panel.add(loginPanel); }
and it adds the component even when panel already has that component.
I have also tried:
function hasComponent(parent, child) {
parent.items.items.forEach(function(item) {
if(item == child){
return true;
}
});
return false;
}
if(!hasComponent(panel, loginPanel)) { panel.add(loginPanel); }
and it also doesn't work.
I have manage to tackle this question by putting and itemId on the panel that I want to load, and on panel.layout.setActiveItem(loginPanel); I have put panel.layout.setActiveItem('itemIdOfPanel');
Could we add our menu items in Starter kit Gitkit NavBar ?
There are two list items in the drop down : Manage Account and Sign Out.
Is it possible to add a third option with a URL link ( say like Update Profile ) ?
The html for the #navbar gets loaded through Javascript code of Gitkit.
I use GAE Python.
Possible solutions which I could think of are :
After my webpage loads completely, I could add my own <li> items to the list of dropdown menu provided by #navbar.
Or
Write a custom "Sign In cum User Info " ( #navbar ) widget.
Is there a better and simpler approach ?
MY REQUEST TO GITKIT TEAM FOR ENHANCEMENT
It would be great if we could provide our custom menu items along with their URL links as options to below JS code which loads #navbar :
<script type=text/javascript>
window.google.identitytoolkit.signInButton(
'#navbar', // accepts any CSS selector
{
widgetUrl: "http://www.mywebsite.com/oauth2callback",
signOutUrl: "/",
// Example of possible solution ( my suggestion ):
custom_menu_item__1__name : "item_1", // My Custom Menu Item 1
custom_menu_item__1__link : "http://site/link_url_1",
::
custom_menu_item__n__name : "item_1", // My Custom Menu Item n
custom_menu_item__n__link : "http://site/link_url_1",
}
);
</script>
UPDATE
Temporary Fix = I have added the needed menu options using jquery temporarily. Code snippet provided below to help anyone with similar needs till official solution arrives :
On page load,
custom_menu_add_job_id = setInterval(function(){
add_custom_menu();
}, 5000);
function add_custom_menu(){
if ($("#navbar").find(".gitkit-user-card-menu").length){
$(".gitkit-user-card-menu").append($("<li class='gitkit-user-card-menuitem' id='smh_user_profile' tabindex='0'> <img src='/images/person_32x32.png' class='user_profile_menu_icon' > Profile </li>")
.click(function(){
window.location.href = window.location.protocol + "//" + window.location.host + "/user/";
})
);
clearInterval(custom_menu_add_job_id);
}
}
If you want, you could check it live at ShowMyHall.
Customized menu items are now supported in Google Identity Toolkit javascript widget. Examples:
window.google.identitytoolkit.signInButton(
'#navbar', // accepts any CSS selector
{
widgetUrl: "...",
dropDownMenu: [
{
'label': 'Check Configuration',
'url': '/config'
},
{
'label': 'Sign out',
'handler': function() {google.identitytoolkit.signOut();}
},
{
'label': 'Manage Account',
'handler': function() {google.identitytoolkit.manageAccount();}
},
]
};
Until this feature arrives, I also implemented a similar temporary fix that you outlined at the end of your question. I got around using a timer as follows (note that my gitkit is using the div login):
$(window).load(function() {
$("#login").hover(function() {
add_custom_menu_items();
})
});
function add_custom_menu_items(){
if ($("#login").find(".gitkit-user-card-menu").length == 1){
if ($("#my_data_link").length == 0) {
$(".gitkit-user-card-menu li:eq(0)").after($('<li class="gitkit-user-card-menuitem" id="my_data_link" tabindex="0">My data</li>'));
}
}
}
Basically when you hover over the div it adds the menu item, but only if it hasn't already been added.
The navbar drop down menu does not support images but if you really need that, here's a hacky way to do it in jquery:
var config = {...}; // your config which includes the custom drop down menu.
// Render button on load. (now supported)
window.onload = function() {
window.google.identitytoolkit.signInButton(
'#navbar', // accepts any CSS selector
config);
// This will modify the html content of the first option in drop down menu.
// Make menu dom changes.
jQuery('#navbar li:first-child').html('<img src="img.png">My Label');
}
I have an element that appears when the user clicks a button elsewhere on the screen. The element appears to come out of the top of the screen. The element by default needs to be tucked out of view above the screen, so I will have a margin-top style that is based on the height of the element (and will be a negative value). This cannot be hardcoded in css because the element height may vary. When I click the button, I want the element margin-top to change to 0 and I want a transition animation.
The sample shown on angularJS documentation is for adding a removing a class. This would work fine if I knew the values to be set and could code them in CSS, however I cannot. What is the correct way to solve this?
The code below works for displaying and hiding my element using a margin but there is no animation. How do I trigger an animation here when the margin changes?
https://docs.angularjs.org/guide/animations
Quote Total: {{salesPriceTotal + taxesTotal - tradeInsTotal | currency}}
<div class="totals" ng-style="setTopMargin()">
// totals stuff here.
</div>
$scope.setTopMargin = function() {
return {
marginTop: $scope.marginTop
}
};
$scope.$watch('showTotals', function() {
var margin = $scope.showTotals ? 10 : -160 + $scope.modelTotals.length * -200;
$scope.marginTop = margin.toString() + 'px';
});
I added the following code per a suggested solution, but this code is never hit.
myApp.animation('.totals', function () {
return {
move: function (element, done) {
element.css('opacity', 0);
jQuery(element).animate({
opacity: 1
}, done);
// optional onDone or onCancel callback
// function to handle any post-animation
// cleanup operations
return function (isCancelled) {
if (isCancelled) {
jQuery(element).stop();
}
}
},
}
});
As the documentation explains: "The same approach to animation can be used using JavaScript code (jQuery is used within to perform animations)".
So you basically needs to use animate() from jQuery to do what you want.
I am working with Twitter Bootstrap and ran into something I could not fix when testing on iPad and iPhone. On mobile (at least those devices) you need to click to engage the tip or popover (as expected). The issue is that you can never close it once you do. I added a listener to close it if you click it again, but I find it hard to believe that the default behavior would not be to click to remove it. Is this a bug in Bootstrap popover and tooltip?? My code is below - it seems to work, but ONLY if you click the same item that created the tip or popover - not anywhere on the page (could not get that to work).
Code to fire:
$(function () {
//Remove the title bar (adjust the template)
$(".Example").popover({
offset: 10,
animate: false,
html: true,
placement: 'top',
template: '<div class="popover"><div class="arrow"></div><div class="popover-inner"><div class="popover-content"><p></p></div></div></div>'
//<h3 class="popover-title"></h3>
//Need to have this click check since the tooltip will not close on mobile
}).click(function(e) {
jQuery(document).one("click", function() {
$('.Example').popover('hide')
});
});
});
HTML:
<a href="javascript:void(0);" class="Example" rel="popover" data-content="This is the Data Content" data-original-title="This is the title (hidden in this example)">
Thanks in advance!

I tried dozens of solutions posted to stackoverflow and other various corners of the web, and the following is the only one that worked for me!
Explanation
As noted here, you can a CSS-directive the element in order to make it touch-device-clickable. I can't tell you why that works or what's going on there, but that seems to be the case. So, I want to make the entire document aka body clickable on mobile devices, which will allow me to touch anywhere to dismiss the popover.
Popover JS
$(function () {
$('[data-toggle="popover"]').popover({ trigger: "hover"}})
});
Directions
1. Install Modernizr
I'm using rails, so I used the gem.
gem 'modernizr-rails'
2. Create a touch class with a css-directive
Add the following to your CSS:
.touch {
cursor: pointer
}
3. On touch devices only, add the touch class to the body
If you want other elements to be clickable, instead of the entire body, add the touch class to them.
if (Modernizr.touch) {
$( "body" ).addClass( "touch" );
}
That's it! Now, you can use your popover normally on desktop (even with hover-trigger) and it will be touch-dismissible on mobile.
I had the same problem with my IPad. But in browser it works fine. Solution for me was adding listeners for all possible element that i can hide tooltip:
$('*').bind('touchend', function(e){
if ($(e.target).attr('rel') !== 'tooltip' && ($('div.tooltip.in').length > 0)){
$('[rel=tooltip]').mouseleave();
e.stopPropagation();
} else {
$(e.target).mouseenter();
}
});
Yes, it's small overhead to send event for all tooltips, but you can't define which element tooltip is showing.
Main concept is that make popover manually on mobile device
$(document).ready(function() {
if ('ontouchstart' in window) {
$('[data-toggle="popover"]').popover({
'trigger': 'manual'
});
}
});
Refer following code snippet to get it works:
$('[data-toggle="popover"]').popover();
$('body').on('click', function (e) {
$('[data-toggle="popover"]').each(function () {
//the 'is' for buttons that trigger popups
//the 'has' for icons within a button that triggers a popup
if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
$(this).popover('hide');
}
});
});
This is the easiest way of detecting clicks on the body and close all the tooltips on the page.

Solution on this jsfiddle,
test on iOS (iPad and iPhone), Android and Windows.
$(document).ready(function(){
var toolOptions;
var toolOptions2;
var isOS = /iPad|iPhone|iPod/.test(navigator.platform);
var isAndroid = /(android)/i.test(navigator.userAgent);
///////////////////////////////////////// if OS
if (isOS){
toolOptions = {

};
$('.customtooltip').tooltip(toolOptions);
$('.customtooltip').css( 'cursor', 'pointer' );
$('body').on("touchstart", function(e){
$(".customtooltip").each(function () {
// hide any open tooltips when the anywhere else in the body is clicked
if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.tooltip').has(e.target).length === 0) {
$(this).tooltip('hide');
}////end if
});
});

};
