使用 AngularJS 获取图像请求 [英] Image Get Requests with AngularJS
问题描述
我将要在 HTML 中呈现的图像的源字符串存储在 AngularJS 控制器中,但是在 Angular 控制器初始化之前它会产生 404.
这是 HTML:
<img src="{{imageSource}}">
角度控制器:
var Cont = function($scope) {$scope.imageSource = '/tests.png';}
我得到的错误(%7D%7D
对应于模板中的 {{
).
GET https://localhost:9000/%7B%7BimageSource%7D%7D 404(未找到)
我怎样才能防止这种情况发生?也就是说,只有在 Angular 控制器初始化后才加载图像?
尝试将 src 替换为 ng-src 以获取更多信息,请参见 文档:
<块引用>在 src 属性中使用像 {{hash}} 这样的 Angular 标记不起作用右:浏览器将从带有文字文本的 URL 中获取{{hash}} 直到 Angular 替换 {{hash}} 中的表达式.这ngSrc 指令解决了这个问题.
<img ng-src="{{imageSource}}">
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?
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>
