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 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 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.
Let's say that I have a simple loop like
<div ng-repeat="item in items">{{item.foo}}<br></div>
or
<div ng-repeat="item in items" ui-view="itemView"></div>
How can I avoid rendering defining tag (div) to get:
Foo 1<br>
Foo 2<br>
Foo 3<br>
instead of:
<div>Foo 1<br></div>
<div>Foo 2<br></div>
<div>Foo 3<br></div>
What for: I need this i.e. to creating table rows where wrapping <tr> with div is not allowed, YES I know that I can use <tr ng-repeat=... for simple cases, anyway I'd prefer to move rendering tr tag into itemView as well (I have several conditions to check for adding i.e. proper CSS classes, otherwise I'll need to add these classes into each td in row)
By creating custom directive with replace: true attribute you can replace the original html div with the directive's template
here is an example inspired from the ng-book:
<div my-directive></div>
app.directive('myDirective' function() {
return {
template: '<div>my directive without replacement</div>
}
});
the html will keep the and inject inside it the directive's template like:
<div my-directive>
<div>my directive without replacement</div>
</div>
But if you set "replace: true" like:
app.directive('myDirective' function() {
return {
replace: true
template: '<div>my directive with replacement<div>'
}
});
then there will be only the directive's template, which replaced the original
<div>my directive with replacement<div>
you can use tbody:
<tbody ng-repeat="item in items">
<tr>
<td>{{ item.foo }}</td>
</tr>
</tbody>
Within a ng-repeat I have a ng-switch conditional. I want the value of the ng-switch argument to be a binding. However the curly-bracket binding doesn't seem to be converted into the expected generated value. I'm aware that ng-switch creates a new scope, and that is surely causing the problem. I know about a 'dot' work-around but as the values here are coming from a service via a controller query, I can't figure out how to implement it in this situation.
html
<tr ng-repeat="user in users">
<td ng-switch on="editState"><p ng-switch-when="noEdit">{{user.username}}</p><input type="text" value="{{user.username}}" ng-switch-when="{{user.username}}"></td>
</tr>
controller.js
$scope.users = Users.query();
-edit-
this is the function that triggers the switch
$scope.editUser = function(usernameEdit) {
$scope.editState = usernameEdit;
};
A single $scope.editState won't work if you want to be able to edit multiple users at the same time. I suggest putting an edit property on each user, and use that property to control the ng-switch:
<tr ng-repeat="user in users">
<td ng-switch on="user.edit">
<span ng-switch-when="true">
<input type="text" value="{{user.username}}">
done
</span>
<p ng-switch-default>
edit {{user.username}}
</p>
</td>
</tr>
