通过jQuery AJAX获取图像

The following image tag is in my Login Page

以下图片代码位于我的登录页面中

<img id="CaptchaImg" alt="Captcha" src="@url.action("Captcha","Login")" style="" />

Now when I refresh my login Page, it works fine, and gets the image from the controller, but when I logOut and the login Page renders .the controller method is not being called.Problem is only in IE works fine on Chrome.Is there are work around? Can I do something with jQuery Ajax call to the controller, I tried this but the success method is not called. Is there any other way?

现在，当我刷新我的登录页面时，它工作正常，并从控制器获取图像，但是当我登录和登录页面渲染时，控制器方法没有被调用。问题只在IE中正常运行Chrome.Is那里正在努力？我可以用jQuery Ajax调用控制器做一些事情，我试过这个但是没有调用成功方法。还有别的办法吗？

$.ajax({
    type: "GET",
    url: '/Login/CaptchaImage',
    datatype: "image",
    success: function(data) {
        debugger
        $('#CaptchaImg').attr('src', data);
    }
});

2 个解决方案

#1

Try this

尝试这个

$.ajax({
    type: "GET",
    url: '@Url.action("Captcha","Login")',
    dataType:"image/jpg",
    success: function (data) {
        $('#CaptchaImg').attr('src', data);
      }
 });

web Server should return base64 Data. like this

Web服务器应返回base64数据。喜欢这个

{ base64Data:"blahblahblah" }

your ajax request content-type could be plain json ; in your success function in ajax you could do like this

你的ajax请求内容类型可以是普通的json;在你在ajax的成功功能中，你可以这样做

    success:function(data){
     var src="data:image/png;base64,"+data.base64Data;
      $('#CaptchaImg').attr(src,src)
}
