Different ng-include's on the same page: how to send different variables to each?

Tags:

angularjs

I've got a page in my AngularJS app in which I would like to include the same html partial, but with different variables. If I do this in my main html:

<div id="div1" ng-include src="partials/toBeIncluded.html onload="var='A'"> <div id="div2" ng-include src="partials/toBeIncluded.html onload="var='B'"> 

And toBeIncluded.html looks like

<div>{{var}}</div> 

Both div's will look like

<div id="div1"><div>B</div></div> <div id="div2"><div>B</div></div> 

I guess it has to do with the fact that the same onload gets called for al the ng-includes. So how do I send different variables to each different include?

The expression passed to onload evaluates every time a new partial is loaded. In this case you are changing the values of var twice so by the time both partials are loaded the current value will be B

You want to pass different data to each partial/template (with the underlying html file being the same). To achieve this, as Tiago mentions, you could do it with different controllers. For example, consider the following

<body ng-controller='MainCtrl'>       <div ng-include src='"toBeIncluded.html"' ng-controller='ctrlA' onload="hi()"></div>   <div ng-include src='"toBeIncluded.html"' ng-controller='ctrlB' onload="hi()"></div> </body> 

Here, we have two partials, each with its own scope managed from their own controller (ctrlA and ctrlB), both children scopes of MainCtrl. The function hi() belongs to the scope of MainCtrl and will be run twice.

If we have the following controllers

app.controller('MainCtrl', function($scope) {   $scope.msg = "Hello from main controller";   $scope.hi= function(){console.log('hi');}; });  app.controller('ctrlA', function($scope) {   $scope.v = "Hello from controller A"; });  app.controller('ctrlB', function($scope) {   $scope.v = "Hello from controller B"; }); 

And the contents of toBeIncluded.html are

<p>value of msg = {{msg}}</p> <p>value of v = {{v}} </p> 

The resulting html would be something along the following lines

<p>value of msg = Hello from main controller</p> <p>value of v = Hello from main controller A </p> 

and

<p>value of msg = Hello from main controller</p> <p>value of v = Hello from controller B </p>

Just like what Mark said, but to simplify it a little bit and make it more "on-the fly" is to use the following:

<div ng-repeat="name in ['John']" ng-include="'name-template.html'"></div> <div ng-repeat="name in ['Jack']" ng-include="'name-template.html'"></div>  <script type="text/ng-template" id="name-template.html">    <div>The name is {{ name }}</div> <script>
