asp.net mvc jquery填充图片

如何解决asp.net mvc jquery填充图片

当我单击capthca时，我想重新填充图像。我怎样才能做到这一点？

 public ActionResult Image()
    {
        var builder = new XCaptcha.ImageBuilder();
        var result = builder.Create();
        Session.Add(\"Cap\",result.solution);
        return new FileContentResult(result.Image,result.ContentType);
    }


<script language=\"javascript\" type=\"text/javascript\">
$(document).ready(function () {
    $(\'#images\').click(function () {

        $.ajax({
            url: \"/en/form/Image\",success: function (mydata) {
                $(\"#images\").attr(\"src\",mydata);
            },type: \"POST\"
        });
        return false;
    });
});

   <input type=\"image\" id=\"images\" src=\"<%= Url.Action(\"Image\",\"ContactForms\") %>\"
                        alt=\"Click to refresh\" /> &nbsp; &nbsp;<input type=\"text\" size=\"5\" tabindex=\"1000\" dir=\"ltr\" maxlength=\"5\" name=\"Captcha\" id=\"Captcha\" />

    

解决方法

        

$(\'#images\').click(function () {
    $(this).attr(\'src\',function() {
        // the datetime portion appended to the url avoids caching issues
        // and ensures that a fresh image will be loaded every time
        var d = new Date();
        return this.src + \'?\' + d.getTime();
    });

    // Remark: not sure about the return false here. This will cancel the 
    // default action of the image button => might not be what you need => 
    // adapt to your requirements
    return false;
});

    ,        尝试仅将src属性设置为动态图片网址的网址

<script language=\"javascript\" type=\"text/javascript\">
$(document).ready(function () {
    $(\'#images\').click(function () {
        $(this).attr(\"src\",\"/en/form/Image\");
        return false;
    });
});
