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 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>

In your comment on @jm-'s answer, you mention you want to load your partial inside ng-repeat. To do this, create an array on your $scope, and set the unique values on that array:
$scope.partialStuff = [ 'p1', 'p2', 'p3' ];
Somewhere in your partial:
{{partialVar}}
The HTML:
<div ng-repeat="partialVar in partialStuff">
<div ng-include src="'partials/toBeIncluded.html'"></div>
</div>
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>

I could be wrong but wouldn't it be better to use a Directive?
.directive('foobar', [function factory() {
return {
restrict: 'E',
replace: true,
templateUrl: '/toBeIncluded.html',
scope: {
"var": "="
}
};
}]);
And your HTML
<div ng-repeat="var in data">
<foobar var="var"></foobar>
</div>
Now the foobar element should be replaced with your template. Each having it's own scope.
Specifically, ng-init and onload expressions are evaluated in the parent scope, not the child scope created by the nginclude. Thus you are assigning values to var on the parent scope twice, both of which are happening before the content inside those ng-includes is loaded compiled and evaluated. When each child scope is created it inherits from the parent scope, where var='B'.
Just a heads up, if you include the partial within an ng-repeat, you can still have access to the parent scope's $index. Just include {{$index}} in the partial.
I had the very same problem and I found a way to achieve what I wanted of course it does not look very pretty but still.
I used the ng-repeat which will create a new scope to include the very same template twice with different values like so (dummy example):
<script type="text/ng-template" id="mod-edito.html">
<div class="mod-edito__media">
<img ng-src="{{ edito.cover.src }}" />
</div>
</script>
<div>
<ng-include ng-repeat="edito in [edito_object]" src="'mod-edito.html'"></ng-include>
...
<ng-include ng-repeat="edito in [edito_other]" src="'mod-edito.html'"></ng-include>
</div>
Is that acceptable? I guess so.
I was looking for an alternative, I wanted a js object to send a few parameters into the included partial. This is the evolved version of the one made by @denis-pshenov. You can use a controller to fill the data, or an ng-init.
Basically, something like this,
var myApp = angular.module('myApp',[]);
myApp.controller('Controller', function($scope) {
$scope.ourData = [ { name : 'John', address : 'Paradise' } ];
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-controller="Controller">
<div ng-repeat="data in ourData" ng-include="'partial.html'"></div>
<div ng-init="ourData2 = [ { name : 'Jack', address : 'Paradise' } ]" />
<div ng-repeat="data in ourData2" ng-include="'partial.html'"></div>
</div>
<script type="text/ng-template" id="partial.html">
<div>The name is {{ data.name }} and the address is {{ data.address }} </div>
</script>There is a way to create a universal reusable directive.
Here is what a colleague of mine had come up with (inspired by Knockout.js).
Directive:
(function () {
'use strict';
angular
.module('directives')
.directive('ngWith', ngWith);
function ngWith() {
return {
restrict: 'A',
replace: true,
scope: {
model: '=',
template: '@'
},
template: '<div data-ng-include="template"></div>',
};
}
})();
Usage:
<div data-ng-with="" data-model="parentObj.childObj.whatEver" data-template='my-template.html'></div>
The same "onLoad" does not get called for all ng-includes. Most likely, var is set to A, and then to B. The thing is, it is being shared across both includes, because they are on the same scope. ´var´, as a model in angularJS, is scope-dependant.
In order for your partials to have separate values, they must each have their own scopes. The easiest way to do this would bet to set up a controller or directive and assign it to the Dom element where the ng-include is, and set your value within that scope.
consider you have variable foo inside your partial,
then you will pass foo like this:
<ng-include src="'partials/foo-part.html'" onLoad="foo='bar'"></ng-include>
for more browser compatibility you can pass it like this:
<div ng-include src="'partials/foo-part.html'" onLoad="foo='bar'"></div>
you can also Use onInclude="foo='bar'" instead of onLoad
Just put each ng-include under its own <div> as following:
<div>
<div id="div1" ng-include src="partials/toBeIncluded.html onload="var='A'"/>
</div>
<div>
<div id="div2" ng-include src="partials/toBeIncluded.html onload="var='B'"/>
</div>
Each included HTML will then have its own var in its own scope.
