I am trying to hide the div if any of the buttons in the ng-repeat is clicked. However it doesn't seem to work, it leads me to think if ng-hide or ng-show won't work if it is controlled from within a ng-repeat?
<div data-ng-hide="showChooseHardware">
<table class="table">
<tbody>
<tr data-ng-repeat="hardware in hardwares">
<td>{{hardware.name}}</td>
<td>
<button type="button" class="btn" data-ng-click="showChooseHardware=!showChooseHardware"/>
</td>
</tr>
</tbody>
</table>
</div>
This is due to the fact that ng-repeat creates a new scope for each template and due to how prototypal inheritance works in JavaScript (and AngularJS).
Use an object:
$scope.viewModel = { showChooseHardware: false };
HTML:
data-ng-hide="viewModel.showChooseHardware"
And:
data-ng-click="viewModel.showChooseHardware=!viewModel.showChooseHardware"
A great explanation on the issue can be found here.
I recommend using ng-showinstead in this case since the variable is called showChooseHardware.
ngRepeat directive creates new scope in every iteration,for every item in array.It can make a problem,which you have.

I want to display an element conditionally based on the value of another parameter PaymentTypeid. After setting the condition as below the element Payment Channel is not rendering in the UI:
<tr ng-init="paymentMode='BANK CABS'" ng-if="json.name == 'paymentTypeId' && json.property == '1'">
<td><strong>{{ 'label.heading.paymentchannel' | translate }}:</strong></td>
<td ><span >{{paymentMode}} </span></td>
</tr>
However when i refactor the markup as below the element is showing as :
<tr ng-init="paymentMode='BANK CABS'">
<td><strong>{{ 'label.heading.paymentchannel' | translate }}:</strong></td>
<td ><span >{{paymentMode}} </span></td>
</tr>
PaymentTypeId is in a json array defined as follows in the controller:
scope.details = {};
resourceFactory.auditResource.get({templateResource: routeParams.id}, function (data) {
scope.details = data;
scope.details.paymentMode="";
scope.commandAsJson = data.commandAsJson;
var obj = JSON.parse(scope.commandAsJson);
scope.jsondata = [];
_.each(obj, function (value, key) {
scope.jsondata.push({name: key, property: value});
});
});
In the view PaymentTypeid renders as :
<table class="table" data-ng-show="details.commandAsJson" data-anchor>
<tbody>
<tr data-ng-repeat="json in jsondata">
<td class="width20"><strong> {{json.name}}</strong></td>
<td class="width80">{{json.property}}</td>
</tr>
</tbody>
</table>
Any insight on what i might be getting wrong. Im not entirely sure between using ng-if/ng-show or whether im setting json.property correctly.
Assuming that you have knowledge of scope in AngularJS.
There is a difference between using ng-if and ng-show. Whenever you use ng-if , it creates it own child scope. and you can manage it in custom directive that deals with its child scope (child scope is not available in controller unless you write your code in a way, that will make it available in controller) and you can hack the scope to use it in controller too. But that is not the case in ng-show.
When you use ng-show it will not remove your HTML from the DOM tree but if you use ng-if it will also remove your html from DOM tree. (To assist your confusion which one to use)
You have a scope issue here , if i'm getting it right. Use ng-show and it will work.
<div ng-show="condition">
your html markup
</div>
I have a template here that I want to repeat based on my $scope.dataset.
How do I get ng-repeat to repeat this template for each name?
HTML I have my template as follows
<table>
<tr ng-repeat = "data in dataset">
<td>{{data.name}}</td>
<td>
<div class="progressbar {{data.color}}" ng-style="{width:{{data.width}} + '%'}"
value = "{{data.value}}">
<span id="barValue">{{data.value}}</span>
</div>
</td>
</tr>
</table>
and as you can see, I'm trying to repeat this template inside the table.
dataset is as follows
$scope.dataset=[
{'name':'name1', 'value':34, 'width':34, 'color':'colorRed'},
{'name':'name2', 'value':50, 'width':50, 'color':'colorBlue'},
{'name':'name3', 'value':47, 'width':47, 'color':'colorRed'},
{'name':'name4', 'value':82, 'width':82, 'color':'colorBlue'},
{'name':'name5', 'value':72, 'width':72, 'color':'colorOrange'},
{'name':'name6', 'value':17, 'width':17, 'color':'colorGreen'},
{'name':'name7', 'value':20, 'width':20, 'color':'colorRed'},
]
When I try to use this, nothing pops up.
All I want is for the data to appear for each .name that comes up.
So first question is what am I doing wrong?
Second, is it possible to do all this in a custom directive?
You must be getting $parse error in your console as you are using
{{}} in ng-style
You shouldn't use {{}} interpolation directive inside ng-style directive.
color should be applied as style instead of adding class, you could be applied from ng-style directive.
HTML
<div class="progressbar" ng-style="{width:data.width + '%', color: data.color}"
value = "{{data.value}}">
<span id="barValue">{{data.value}}</span>
</div>
I am working on an app and I cant seem to figure out why my ng-click only works inside of my (single) tr tag but as soon as I put it into another tr tag it stop working. Keep in mind it was working before I used the ng-repeat within the first tr tag. Here is what my code looks like, any advice would greatly help!
<table>
<tbody>
<tr>
<td ng-click="commentOpen = !commentOpen">
<div class="iconsize">Comment Closed</div>
</td>
<td ng-click="switchOpen = !switchOpen">
<div class="iconsize">Switch Closed</div>
</td>
</tr>
<tr>
<td>
<div ng-show="commentOpen == true">
<textarea>Comment Open</textarea>
</div>
<div ng-show="switchOpen == true">
<p>Switch On</p>
</div>
</td>
</tr>
</tbody>
</table>
I had the ng-repeat on the tag which was causing my ng-click to not fire. I ended up moving my ng-repeat to the tbody and the ng-click and ng-show started working again.
ngRepeat creates new scopes for its children, it just usually seems like it's accessing the same scope because this new scope inherits from its parent.
Meaning, commentOpen is actually referring to a property on the wrong scope.
Below are three potential ways for you to fix this:
1) controller as, and always refer to the controller you're after by name
2) $parent.commentOpen (Don't do this! It becomes very confusing as you nest)
3) Instead of commentOpen and switchOpen, you can use an Object (e.g. $scope.openControls = { comment: false, switch: false }, and then in the td tags you would write something like ng-click='openControls.comment = !openControls.comment'). This way it's passed inherited by reference (where as a boolean would be by value), and keeps synced.
I have an ng-if inside an ng-repeat in a template, and the ng-if is not working, even if I change it to just
ng-if="false"
I can make it work by adding
ng-controller="TemplateController"
to a parent div, however when I do this, my controller cannot receive resolved arguments:
resolve: {
myVar: function() {
return "hello world";
}
}
Unknown provider: myVarProvider <- myVar
if I remove the ng-controller, and add
controller: "TemplateController"
after my resolve:, then myVar is passed successfully, however ng-if no longer works
my HTML:
<table>
<div ng-repeat=“row in rows"><tr>
<span ng-if=“row.active==1">
<td>{{row.data}}</td>
<td></td>
<td>{{ row.date | date:"MM/dd/yyyy"}}</td>
<td>
<a href=“stuff”>click me</a>
</td>
</span>
<span ng-if=“row.active > 1">
<td>{{row.otherData}}</td>
<td>{{row.str}}</td>
<td>{{ row.date | date:"MM/dd/yyyy"}}</td>
<td>
<a href=“stuff”>click me instead</a>
</td>
</span></tr>
</div>
</table>
right now, I get a whole bunch of blank cells, and both 'click me' links.
if I remove the tags, it works, but it's not in a table
moreover, not only is the ng-if not working, but any variables I reference inside {{}} are being replaced with blanks (but they also work if is removed)

The golden rule to avoid this problem is
Always have a dot in your angular bindings
ng-if="false"
Does not have a dot. Therefore the value false is being passed to the scope of the ng-if but can't be updated, since false is an immutable boolean value.
The correct way,
ng-if=status.enabled
Where status is an object.
I have the following code :
<div ng-init="showDetail = false">
<table>
<tbody>
<tr ng-repeat="dataTable in arrayTableData">
<td ng-repeat="data in dataTable.data" ng-click="showDetail = true;">{{data}}</td>
</tr>
</tbody>
</table>
<div ng-show="showDetail">
<button ng-click="showDetail = false">Close</button>
</div>
</div>
My variable showDetail changes value when you click on a data of the table, but my div showDetailCell not appear.
If I change the initialisation of showDetail with true the detail appear and disappear when you click on the button, but the click on the cell doesn't display showDetailCell.
ng-repeat will get its own scope. Due to Javascript inheritance, whenever variable from parent object is assigned in child scope will create new variable. It will no more reference to parent object variable. Better use . notation in the scope variable.
Instead of showDetail, use detail.toggle will solve the problem.
