Image Get Requests with AngularJS

问题

I am storing the the source string of an image to be rendered in HTML in the AngularJS controller, however it yields a 404 before the Angular controller is initialized.

Here is the HTML:

 <div ng-controller="Cont">
      <img src="{{imageSource}}">
 </div>

Angular controller:

 var Cont = function($scope) {
      $scope.imageSource = '/tests.png';
 }

And the error I get (%7D%7D corresponds to the {{ in the template).

 GET https://localhost:9000/%7B%7BimageSource%7D%7D 404 (Not Found) 

How can I prevent this from happening? That is, only load the image when the Angular controller has been initialized?

回答1:

Try replacing your src with ng-src for more info see the documentation:

Using Angular markup like {{hash}} in a src attribute doesn't work right: The browser will fetch from the URL with the literal text {{hash}} until Angular replaces the expression inside {{hash}}. The ngSrc directive solves this problem.

 <div ng-controller="Cont">
      <img ng-src="{{imageSource}}">
 </div>

If someone is searching the solution for styling background-image then use this:

<div ng-style="{'background-image': 'url({{ image.source }})'}">...</div>
