Got a problem, here the situation:
I want to uncheck the first checkbox when I uncheck the second checkbox.
Let say, by default both checkbox are checked. When I click second checkbox, I want the first checkbox to uncheck also.
HTML:
<ion-checkbox ng-model="firstCheckbox">First Checkbox</ion-checkbox>
<ion-checkbox ng-model="secondCheckbox" ng-change="uncheckFirstCheckbox(secondCheckbox)">Second Checkbox</ion-checkbox>
JS:
$scope.uncheckFirstCheckbox = function(secondCheckbox) {
if(secondCheckbox.checked === false) {
$scope.firstCheckbox = false;
};
};
The $scope.firstCheckbox turn false but it remain uncheck in HTML.
May I know where could be the problem?
You're trying to access secondCheckbox.checked property but secondCheckbox is already false. You should be only checking secondCheckbox for a false value. Use if(!secondCheckbox) instead for the condition.
Here is a working fiddle of your code.
HTML
<ion-checkbox ng-model="firstCheckbox">First Checkbox</ion-checkbox>
<ion-checkbox ng-model="secondCheckbox" ng-change="uncheckFirstCheckbox(secondCheckbox)">Second Checkbox</ion-checkbox>
JS
$scope.uncheckFirstCheckbox = function(secondCheckbox) {
if (!secondCheckbox) {
$scope.firstCheckbox = false;
};
};

I have a checkbox that I'd like to set the indeterminate state to based on the states of other checkboxes. When I'm on the page that the checkboxes are all in, it updates as expected (i.e. the checkbox is found). But when I navigate to that from another page, my method does not find the checkbox (i.e. returns null).
When I debug in Chrome devtools, I notice
let checkBoxWithIndeterminateState;
let checkbox = false;
fireWhenCheckBoxChanged() {
// returns null when navigating from another page but not when on its own page
checkBoxWithIndeterminateState = document.getElementById('checkBoxWithIndeterminateState')
checkBoxWithIndeterminateState.indeterminate = true
}
Template:
<input type="checkbox" id="checkBoxWithIndeterminateState" data-ng-model="checkbox">
How do I wait until the new template has loaded before my method tries to find the checkbox? I've read some suggestions to use this._$scope.$on('$viewContentLoaded'... but this doesn't work.
Thanks!
What about adding an ng-init directive to your target checkbox and do your logic in it, this way you are sure the element is there, here is a suggestion:
<input type="checkbox" ng-init="initTragetCheckbox()">
In your controller
$scope.initTragetCheckbox = function () {
// your code to execute for other checkboxes
var checkbox1 = document.getElementById("checkbox1");
var checkbox2 = document.getElementById("checkbox2");
....
}
I have a list of checkboxes and at the top a all checkbox. When toggling the all checkbox, all checkboxes will get deselected or selected.
By default/initially, all checkbox is enabled with all checkboxes checked. So, I will deselect the all checkbox and all the checkboxes will uncheck. This passes no with no issues in protractor:
it('all checkbox is deselected', function() {
modelsAllCheckbox.click();
expect(modelsAllCheckbox.isSelected()).to.eventually.be.false;
});
it('all models should be deselected', function() {
ppvPercentages.modelChoices().then(function(modelChoices) {
modelChoices.forEach(function(modelChoice) {
expect(modelChoice.isSelected()).to.eventually.be.false;
});
});
});
this.modelChoices = function(rowNumber) {
return element.all(by.repeater('model in vehicleCheckboxes.models'));
}
Then I re-enable the all checkbox. I visually can see, in the browser, the all checkbox being checked in all the checkboxes successfully being checked/selected. Hoewever, in the test to assert they are all selected fails:
it('all button is re-enabled', function() {
modelsAllCheckbox.click();
expect(modelsAllCheckbox.isSelected()).to.eventually.be.true;
// give time for all models to set
browser.sleep(3000)
});
it('all models are selected', function() {
ppvPercentages.modelChoices().then(function(modelChoices) {
modelChoices.forEach(function(modelChoice) {
expect(modelChoice.isSelected()).to.eventually.be.true;
});
});
})
<div class="overflow-container">
<!-- all checkbox -->
<input type="checkbox"
ng-model="vehicleAllCheckbox.models"
ng-change="toggleAllModels(vehicleAllCheckbox, vehicleCheckboxes.models, vehicleCheckboxes.year)">All
<div ng-repeat="model in vehicleCheckboxes.models | orderBy: 'description' track by model.description">
<!-- the rest of the checkboxes -->
<input type="checkbox"
ng-change="modelCheckboxToggle()"
ng-model="model.checked" >
{{model.description}}
</div>
</div>
I see all the checkboxes are checked in the browser viusally. Why is modelChoice.isSelected() giving false instead of true up re-enabling the all checkbox?
The problem is in the way you are locating the checkboxes. Currently, you are targeting the parent div elements since you are using the by.repeater() locator:
<div ng-repeat="model in vehicleCheckboxes.models | orderBy: 'description' track by model.description">
Instead, point modelChoices to input elements (your checkboxes):
this.modelChoices = function(rowNumber) {
return element.all(by.repeater('model in vehicleCheckboxes.models')).all(by.model('model.checked'));
}
As a side note, I think you can improve the way you are expecting the checkboxes to be selected, by either using .each():
ppvPercentages.modelChoices().each(function (modelChoice) {
expect(modelChoice.isSelected()).to.eventually.be.true;
});
Or, by using .reduce():
var allSelected = ppvPercentages.modelChoices().reduce(function (acc, modelChoice) {
return modelChoice.isSelected().then(function (isSelected) {
return acc && isSelected;
});
}, true);
expect(allSelected).to.eventually.be.true;
Or, there are other ways as well.
I'm using ngRepeat to generate four buttons. Whenever I click one of the buttons, I want to change its color and also execute a function (for now, I'm just using console.log for sake of simplicity). If I click on another button, I want to change its color while reverting the previous button back to its original color.
I have a couple of issues - the first is that I can't seem to get ng-click to accept two commands (the first being the console.log function and the second being the instruction to change the button color). The other issue is that if I take out the console.log function, I end up changing all of the buttons when I click on one.
Any ideas? Here's the plunkr: http://plnkr.co/edit/x1yLEGNOcBNfVw2BhbWA. You'll see the console.log works but the button changing doesn't work. Am I doing something wrong with this ng-click?
<span class="btn cal-btn btn-default" ng-class="{'activeButton':selectedButt === 'me'}" ng-click="log(element);selectedButt = 'me'" data-ng-repeat="element in array">{{element}}</span>
You can create a simple function in your controller which handles this logic:
$scope.selectButton = function(index) {
$scope.activeBtn = index;
}
Then, you can simply check in your template if the current button is active:
<span class="btn cal-btn btn-default" ng-class="{true:'activeButton'}[activeBtn == $index]" ng-click="selectButton($index);" ng-repeat="element in array">{{element}}</span>
I also changed your plunkr
You may convert your element list from string array to object array first.
$scope.array = [
{"name":"first", "checked":false},
{"name":"second", "checked":false},
{"name":"third", "checked":false},
{"name":"fourth", "checked":false}
];
And your log function need to change to:
$scope.log = function(element) {
console.log(element.name);
angular.forEach($scope.array, function(elem) {
elem.checked = false;
});
element.checked = !element.checked;
}
Then, in your HTML:
<button class="btn cal-btn"
ng-repeat="element in array"
ng-click="log(element)"
ng-class="{activeButton: element.checked, 'btn-default': !element.checked}"
>{{element.name}}</button>
Please see the updated plunker here.
I have successfully created a function to toggle the individual rows of my ng-table to open and close using:
TestCase.prototype.toggle = function() {
this.showMe = !this.showMe;
}
and
<tr ng-repeat="row in $data">
<td align="left">
<p ng-click="row.toggle();">{{row.description}}</p>
<div ng-show="row.showMe">
See the plunkr for more code, note the expand/collapse buttons are in the "menu".
However, I can't figure out a way to now toggle ALL of the rows on and off. I want to be able to somehow run a for loop over the rows and then call toggle if needed, however my attempts at doing so have failed. See them below:
TestCase.prototype.expandAllAttemptOne = function() {
for (var row in this) {
if (!row.showMe)
row.showMe = !row.showMe;
}
}
function expandAllAttemptOneTwo(data) {
for (var i in data) {
if (!data[i].showMe)
data[i].showMe = !data[i].showMe;
}
}
Any ideas on how to properly toggle all rows on/off?
Using the ng-show directive in combination with the ng-click and ng-init directives, we can do something like this:
<div ng-controller="TableController">
<button ng-click="setVisible(true)">Show All</button>
<button ng-click="setVisible(false)">Hide All</button>
<ul>
<li ng-repeat="person in persons"
ng-click="person.visible = !person.visible"
ng-show="person.visible">
{{person.name}}
</li>
</ul>
</div>
Our controller might then look like this:
myApp.controller('TableController', function ($scope) {
$scope.persons = [
{ name: "John", visible : true},
{ name: "Jill", visible : true},
{ name: "Sue", visible : true},
{ name: "Jackson", visible : true}
];
$scope.setVisible = function (visible) {
angular.forEach($scope.persons, function (person) {
person.visible = visible;
});
}
});
We are doing a couple things here. First, our controller contains an array of person objects. Each one of these objects has a property named visible. We'll use this to toggle items on and off. Second, we define a function in our controller named setVisible. This takes a boolean value as an argument, and will iterate over the entire persons array and set each person object's visible property to that value.
Now, in our html, we are using three angular directives; ng-click, ng-repeat, and ng-show. It seems like you already kinda know how these work, so I'll just explain what I'm doing with them instead. In our html we use ng-click to set up our click event handler for our "Show All" and "Hide All" buttons. Clicking either of these will cause setVisible to be called with a value of either true or false. This will take care of toggling all of our list items either all on, or all off.
Next, in our ng-repeat directive, we provide an expression for angular to evaluate when a list item is clicked. In this case, we tell angular to toggle person.visible to the opposite value that it is currently. This effectively will hide a list item. And finally, we have our ng-show directive, which is simply used in conjunction with our visible property to determine whether or not to render a particular list item.
Here is a plnkr with a working example: http://plnkr.co/edit/MlxyvfDo0jZVTkK0gman?p=preview
This code is a general example of something you might do, you should be able to expand upon it to fit your particular need. Hope this help!
I need help with a script to add an "active" class to a div when a hidden checkbox is checked. This all happening within a somewhat complex form that can be saved and later edited. Here's the process:
I have a series of hidden checkboxes that are checked when a visible DIV is clicked. Thanks to a few people, especially Dimitar Christoff from previous posts here, I have a few simple scripts that handle everything:
A person clicks on a div:
<div class="thumb left prodata" data-id="7"> yadda yadda </div>
An active class is added to the div:
$$('.thumb').addEvent('click', function(){
this.toggleClass('tactive');
});
The corresponding checkbox is checked:
document.getElements("a.add_app").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_select_p" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
Now, I need a fourth ( and final ) function to complete the project (using mootools or just plain javascript, no jQuery). When the form is loaded after being saved, I need a way to add the active class back to the corresponding div. Basically reverse the process. I AM trying to figure it out myself, and would love to post an idea but anything I've tried is, well, bad. I thought I'd at least get this question posted while I work on it. Thanks in advance!
window.addEvents({
load: function(){
if (checkbox.checked){
document.getElements('.thumb').fireEvent('click');
}
}
});
Example: http://jsfiddle.net/vCH9n/
Okay, in case anyone is interested, here is the final solution. What this does is: Create a click event for a DIV class to toggle an active class onclick, and also correlates each DIV to a checkbox using a data-id="X" that = the checkbox ID. Finally, if the form is reloaded ( in this case the form can be saved and edited later ) the final piece of javascript then sees what checkboxes are checked on page load and triggers the active class for the DIV.
To see it all in action, check it out here: https://www.worklabs.ca/2/add-new/add-new?itemetype=website ( script is currently working on the third tab, CHOOSE STYLE ). You won't be able to save/edit it unless you're a member however, but it works:) You can unhide the checkboxes using firebug and toggle the checkboxes yourself to see.
window.addEvent('domready', function() {
// apply the psuedo event to some elements
$$('.thumb').addEvent('click', function() {
this.toggleClass('tactive');
});
$$('.cbox').addEvent('click', function() {
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb tactive");
}
else{
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb");
}
}
});
// Add the active class to the corresponding div when a checkbox is checked onLoad... basic idea:
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
$('c_field_tmp_'+i).set("class", "thumb tactive");
}
}
document.getElements("div.thumb").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_tmp_" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
});
