In my extjs project, I have some panel's to which I am showing toolbar on mouseEnter event. This is working fine. But when I just update the panel with new html then the mouseenter event is not working on it.
panel.update('hello');
Then I realised through Chrome developer tool that the update method is erasing the last nested div inside panel before writing the new text to it (ie 'hello').
Each panel has 3/4 nested div's but when we use update(), the panel has only 2 nested div's?
This was the main reason which was not invoking the mouseenter event on the panel because I think the Ext is unable to identify the panel as a valid panel after update() method.
Anyway, later I solved this issue by checking the panel variable in chrome console like below.
panel.body.dom.childNodes[0].children[0].childNodes[0].data = 'hello';
The above implementation looks disgusting but it worked for me. Any other nice way to do this?
Edit :
//In controller
this.control({
'#monthCalendar>panel>panel': {
render: function(container){
container.on('mouseenter',function(){
//do something here
},container,{element: 'el'});
}
}
})
Before Update:
<div class="x-panel x-box-item x-panel-default" id="panel-1078" style="left: 870px; top: 0px; margin: 0px; width: 174px; height: 52px;">

I am available on Sencha chat room.
Your event handler stops working because your update() erases the inner elements added by the panel's layout.
You are using either HBox or VBox layout on your panel, which adds additional HTML elements inside the main one, as you noticed. If you call update() on the main component's element, you erase the inner elements added by the layout, including that on which your event handler was listening.
The solution is to either:
use a simpler layout on your panel, such as Auto;
or
update the inner element added by the layout:
panel.getLayout().targetEl.update('Updated');
If you want to update the content of a panel, you should call
panel.body.update('hello');
This will update content area element only and will not ruin the panel integrity. As far as I know, calling update directly on panel is wrong, because call to function inherited from AbstractComponent will not take into account internal panel's structure and will overwrite essential panel's markup.

I have a modal window that shows a few data that also has Images which open in Blueimp gallery. The problem I have is, when the image is opened in BlueImp gallery, the image is not vertically aligned in the middle of the screen. Its either to the bottom or to the top and it depends on where I have scrolled in the modal window. I need to go to the middle of the modal window and open the gallery in which case the Lightbox looks centered. This issue doesnt happen when blueimp is used directly in the page without a modal. It appears the blueimp gallery's lightbox is centered to the whole modal height instead of the viewport height. How can I override that for blueimp inside modal windows only? Is there a css fix or js fix to override this when blueimp is used in boostrap modals?
Here is a sample of my set-up:
<div uib-modal-window="modal-window" class="modal fade" role="dialog" size="xl" index="0" animate="animate" ng-style="{'z-index': 1050 + $$topModalIndex*10, display: 'block'}" tabindex="-1" uib-modal-animation-class="fade" modal-in-class="in" modal-animation="true" style="z-index: 1050; display: block;">
<div class="modal-dialog modal-xl">
<div class="modal-content" uib-modal-transclude="">
<div class="lightBoxGallery">
<a ng-repeat="image in vm.ngModel" ng-href="{{::vm.imageurl(image.name)}}" data-gallery="">
<img ng-src="{{::vm.getImage(image.name)}}" class="img-responsive img-thumbnail animated fadeIn">
</a>
<div id="blueimp-gallery" class="blueimp-gallery">
<div class="slides"></div>
<h3 class="title"></h3>
<a class="prev">‹</a>
<a class="next">›</a>
<a class="close">×</a>
<a class="play-pause"></a>
<ol class="indicator"></ol> </div>
</div>
</div>
</div>
</div>
My set-up: Angular 1.5 + Bootstrap 3 + Bootstrap UI + BlueImp Gallery
UPDATE:
The problem I am having here is, my Bootstrap Modal window has overflow-y as scrollable and it has a fixed positioning:
.modal-open .modal {
overflow-x: hidden;
overflow-y: auto;
}
.modal {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1050;
display: none;
overflow: hidden;
-webkit-overflow-scrolling: touch;
outline: 0;
}
And when the blueimp-gallery is opened, as a child div with fixed position, it is positioning the Div to the center of the parent's fixed position instead of center of the viewport:
.blueimp-gallery {
position: fixed;
z-index: 999999;
overflow: hidden;
background: #000;
background: rgba(0,0,0,.9);
opacity: 0;
display: none;
direction: ltr;
-ms-touch-action: none;
touch-action: none;
}
The blueimp-gallery is aligning to the middle, but I dont want it aligning to the middle of parent (modal) div. I want it aligned to the middle of viewport. For example, in my laptop, my modal has a height of 2000px where as my viewport height is a lot less like 860px. That is why the gallery lightbox is opening either to the top or bottom of the viewport unless the user is right in the middle of the modal window. If I place the blueimp-gallery directly in the body without the modal window, I dont have this issue. But in this use case, I have to place the blueimp-gallery inside a Modal window that has variable height depending on the dynamic content loaded in it.
I am still stuck on this, does anyone have a suggestion to this problem please?
The only way I was able to resolve this issue was to pull the "#blueimp-gallery" element out of the Modal Window and then insert it again as a direct child of the body element. Using Jquery, I added this code that fixed the issue:
$(document).ready(function(){
$("#blueimp-gallery").prependTo($("body"));
});
Now, after the above code, the BlueImp Gallery's fixed position is relative to the body element and therefore the height is that of the viewport. The Modal height no longer affects the BlueImp Gallery's height since it is now placed as a direct child of body element.
You should try to put the blueimp in a div with the class row and then another div with the class col-md-6 not 100% sure but it should be alligned in the middle then.
<div class="container">
<div class="row">
<div class="col-md-6">
<div id="blueimp-gallery" class="blueimp-gallery vcenter ">
...
</div>
</div>
</div>
Edit tried it it has to have container tag above it to.
most likely this is not the sollution to getting it to the center vertically but this is worth a try i guess
ADDITION
.vcenter {
display: inline-block;
vertical-align: middle;
float: none;
}
create a costum tag add it in a css file and call on it.
Under my root div react creates another div "automatically". Is there a way to add a class to that div? I need to add height: 100% to it to prevent the background content to scroll in mobile when an overlay is shown.
This is how it is shown when i inspect the element on the site. I need to add height:100% to the data-reactroot div when a button is clicked. But that div is nowhere in my source code.
<div id="root">
<div data-reactroot data-reactid="1" data-react-checksum="161698...
I could add this code in the container's componentDidMount()
let root = document.querySelectorAll('[data-reactroot]')[0];
if (root) {
root.style.height = '100%';
}
But isnt there a better way to do it? This feels like kind of hacky (in a bad way)
#root > [data-reactroot] { height: 100% } in your CSS should work.
Or just the tag itself:
[data-reactroot] { ... }
If you want to use in-line css, just make your top div position is absolute and left, top, right, bottom is zero.
So if you inspect the element:
<div id="root">
<div data-reactroot>
<div style="position: absolute; top: 0px; left: 0px; right: 0px; bottom: 0px>
....
So simple by using the id reference
#root{
/* your css here! */
}
I have a web page built in angularjs .
<html>
<head></head>
<body ng-app="app1" ng-controller = "ctrl1">
<header></header>
<div ng-view></div>
<footer></footer>
</body>
</html>
Here the header and footer is always fixed, but in content section when I am doing routing and in one of the view I have header which I always want to be fixed.
The problem is when use position:fixed for that content header and while moving the scroll of main page , the content below the header seems to move upwards.
so my question is how can I create that header in such a way that while scrolling down the content section or main section the header should always be fixed.
Any help is appreciated !!!
Thanks
WHat you need to do is add a padding-top to you content that is equal to the height of your header. That way your content will never scroll up below the header
.content-header {
height: 30px;
position: absolute;
top: 0px;
}
.content-container {
padding-top: 30px;
overflow: scroll;
position: relative;
}
Use overflow: scroll; for that div.
<div class="content" ng-view></data>
.content {
width: 150px;
height: 150px;
overflow: scroll;
}

You could use bootstrap to ease your task.

I would like to present desktop users with a phone image and overlay an iframe that displays an external website to fit the phone screen. Both should be responsive.
If possible, When the visitor is already on a mobile phone then they should see the the same thing that is seen on the desktop, but without the phone as a frame.
Does anyone know how this can be done?
Here is the method that I use for responsive stacked divs.
This will work for both methods you asked for, but I would suggest not loading a desktop version to the mobile users, for bandwidth purposes being they have no option to prevent the content to load.
It is based on percentages and from my experience, it has the best responsive results, with minimal coding. Once you replace the photo, you will need to adjust the width and height percentage values in the CSS to scale as desired.
The Markup
<div id="container">
<div id="photo">
<img src="https://d3nj7353mvgauu.cloudfront.net/media/categories/iphone-6-6s-6-plus-6s-plus-1.png" width="100%" height="auto">
<div id="site">
<iframe src="https://www.godaddy.com/" width="99%" height="99%"></iframe>
</div>
</div>
</div>
The CSS
#container {
position: relative;
width: 100%;
max-width: 600px;
height: auto;
}
#photo {
position: absolute;
width: 100%;
}
#site {
position: absolute;
width: 100%;
max-width: 43%;
height: 76%;
top: 11.75%;
left: 28.25%;
border: none;
}

In my AngularJS app there is a controller which contains a list with messages:
$scope.messages = []
This list is updated as the application runs. In the template it is rendered in the following way:
<div style="height: 200px; overflow: auto">
...
<li ng-repeat="msg in messages">{{msg}}</li>
...
But when more messages comes than fits the 200px height, the scroll remains on the top.
How to automatically scroll to the bottom of the message list?
There is a directive "scroll-glue" from this library https://github.com/Luegg/angularjs-scroll-glue that solves the problem.
Just add scroll-glue directive to the div:
<div style="height: 200px; overflow: auto" scroll-glue>
...
