So I have a dialog directive that I'm using in a template. I'm doing something like:
<my-dialog>
<div>
<ng-include src="'myTemp.html'"></ng-include>
</div>
<my-dialog>
For some weird reason when I open my dialog, nothing appears when it's opened the first time. The second time populates my dialog with myTemp.html. Do I need to do things with $templateCache to notify angular about myTemp.html so that it works the first time?
Sorry I did have the '' around the src, I just forgot to add it for this submission =/.
ng-include src is expecting a variable, isn't it?
So, I'm guessing that the src in your example should be wrapped in ''. So, it will be:
<ng-include src="'myTemp.html'"></ng-include>
See if that helps.
Here's the official documentation: https://docs.angularjs.org/api/ng/directive/ngInclude
src in the ng-include tag expects an expression. so to pass it a string you need to put quote around it:
<ng-include src="'myTemp.html'"></ng-include>

I have a template which is nested inside another template which I want to load when i click on a button.
So the nested template is loaded dynamically. This is what I have done so far.
This is the main body.html (this loads when a url is provided in the browser e.g. http://url#/newtemplate)
<div ui-view> </div>
Other section of the code has been removed for brevity
This is the new_template.html which I expects it to show when I click a button.
When I put a template name directly like below i.e. when I hard code it
<div ui-view="number1"></div>
It loads the template fully.
This is the dynamic model
<button ng-model="template_name" ng-value="number1">Button1</button>
<div ui-view="{{template_name}}"></div>
{{template_name}}
The above does not load the template as I expected. but it shows the string number1 when
the button is clicked
What can I do for it to load the template....
This is my controller
.state('parent',{
url: '/newtemplate',
views:{
'':{
templateUrl: "parent.tpl",
contoller:"controller",
},
'number1#parent':{
templateUrl:"number1.tpl",
contoller:"formcontroller"
},
'number2#parent':{
templateUrl:"number2.tpl",
contoller:"formcontroller"
},
'number3#parent':{
templateUrl:"number3.tpl",
contoller:"formcontroller"
}
}
})
Strange enough when I used the dot notation it did not work so I have to use the absolute naming method.
I also noticed that when I added the nested views as shown above the time it takes before the template gets loaded take a very long time.
Please I would appreciate any help which can allow me to load a nested view at runtime (possibly very fast)
Expecting more answer
I still hope that the I can make use of ui-view/ui-router because of the ability to make use of controller.
I'm not sure you can use uiView to load html dynamically.
I would try another possible solutions:
Use directives
Using ngInclude
I'll leave you an example with ngInclude: https://next.plnkr.co/edit/M5hl71mXdAGth2TE?open=lib%2Fscript.js&deferRun=1&preview
Ok, I've seen similar questions on SO but still don't understand this issue.
I have a directive for date input, using ngModelController. I have another directive, to which you can pass the model controller, and it checks if the model has errors, and sets appropriate classes to the element.
So the markup looks like this:
<form name="myForm">
<div class-validation="myForm.date">
<date-input ng-model="date" name="date"></date-input>
</div>
</form>
Since we have date-input inside of our form, and it has the name attribute and ng-model, the ngModelController will be added to myForm under the name date, which is exactly what we pass to class-validation directive.
Now the problem is, if I use templateUrl for my date-input directive, the class-validation directive receives undefined. But when I use inline template instead, everything works as expected.
Here is a Plunker that demonstrates the problem exactly.
http://plnkr.co/edit/Cygawxjp4WN9xRbTEXWU?p=preview
Comment out line 41 and uncomment line 42 in script.js to see the problem. The validation doesn't work and if you open browser console, you'll see that class-validation parsed myForm.date as undefined.
Why is this happening? I am guessing that requiring template from an url is async operation, but it shouldn't make a difference to the developer. I wasted hours and hours trying to find out what's causing this. Thanks.
Here is my case:
I have a div which needs to get some html injected from a function:
<div ng-bind-html="myCtrl.getMyLink()"></div>
in my controller I have:
this.getMyLink = function () {
return '<a ui-sref="app.go.to.state1">my link</a>';
}
It works but not at all. All I have at the end in my html is only
<a>my link</a>
It's a link but the ui-sref redirection is not working.
There is surely something I'm missing.
How can I fix that?
ng-bind-html does not work with ui-sref directive. Just use href="path/to/state1" instead
The content inside ng-bind-html doesn't get compiled by angular, it is intended for static html.
You would need to use your own directive instead and either set a template or do your own compiling with $compile.
Alternatively you might be able to use ng-include. There aren't enough details given for your use case to help much more
I have a need to use the same directive within a directive, depending on a conditional param. However, when ever i try to do it, it seems to go to an endless loop. As i understand, it tries to pre-load the templates and that causes an endless recursion and at the end, it just throws me the following error:"RangeError: Maximum call stack size exceeded".
I have created an example in fiddle.. as you can see in the example, when the param's value is "1", it creates the error (even when the second level param is valued as "2" so it shouldn't have real recursion issues in the controller/app).
https://jsfiddle.net/qh9nh1gx/
"custom-directive"'s template:
<div>
<div ng-if='info==1'><div custom-directive info='2'></div></div>
<div ng-if='info==2'>DONE,single.</div>
</div>
Thanks
I have found 2 options to deal with the issue, the first one, is exactly what Jju described - creating a new "compiler" method (it can be grabbed from the url he sent).
The second option - always using an additional template for the "recursive" parts of the directive. For example, in my directive, i had a "ng-repeat" part that depending on the items value, it could request to display the directive again. while i used "ng-include" to have the other directive, it worked.
<div ng-repeat="item in items" ng-include="'inline-possibly-recursive-template"'></div>
in that template, you can call the directive again without any issues..
I hope that it will anyone else that will stumble into that issue.
You can look into https://stackoverflow.com/a/19065910/1680674 that describe a common approach to create directive that use himself inside
I have a AngularJS application where I am loading data from a REST service.
Now what sometimes happens is that the brackets {{}} used to access values from scope are rendered and after that replaced by the real values. Now what I d like to do is add a ng-switch to the top DIV of the application and check whether a global var (e.g. pageLoaded (true|false)) is true or false. If its true, I d like to load the normal page, if its false, I d like to print something like "loading...". So my problem is how can I get notified (e.g. through a Angular Event) if all the data is ready, and is added to scope? Because after that I dlike to set pageLoaded to true.
Is there a way to do this in a generic way? I don't like to implement this per page.
Thanks a lot in advance.

You should use ng-cloak for that - http://docs.angularjs.org/api/ng.directive:ngCloak
For showing a loading panel, you can do something like:
<div ng-hide="true">Loading...</div>
So when angular finishes loading, ng-hide will occur and hide the loading panel.
Use ng-cloak to get rid of this sort of problems. And make sure you apply the ng-cloak directive to the body of the page so that this doesn't show up till the data is loaded properly. And use the following styling in your CSS file.
[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
display: none;
}
Note: you can even create some other element or div, thats something like a popup or notification bar, which shows "please wait till the data is comnpletely loaded". Set this div to display:none initially and in the Ajax call, change the display property to block/inline as needed and finally make it dispay:none after the success call back.. :)
One of the solutions is you can use ng-bind instead of using {{}} which will show ugly {{}} when the value is not rendered.
<div ng-bind="value">Loading ...</div>
For anyone who is having a problem more to do with the actual question than OP's specific scenario:
I had a fragment that was getting loaded-in after/by the main partial that came in via routing.
I needed to run a function after that subpartial loaded and I didn't want to write a new directive and figured out you could use a cheeky ngIf
Controller of parent partial:
$scope.subIsLoaded = function() { /*do stuff*/; return true; };
HTML of subpartial
<element ng-if="subIsLoaded()"><!-- more html --></element>
