从悬浮窗的Ajax响应获取响应文本 [英] fetch response text from ajax response of a dropzone

问题描述

我已经接到了悬浮窗上传成功以下响应。

I've got the following response from dropzone successful upload.

在此我要取的responseText

From this I need to fetch the responseText

我想：的console.log（response.xhr.responseText）这显示完整的响应文本

I tried: console.log(response.xhr.responseText) this show the full response text.

当我尝试获取 IMG 从responseText的像这样的的console.log（response.xhr.responseText.img）控制台掷未定义

When i try to fetch img from responseText like this console.log(response.xhr.responseText.img) the console throw undefined

推荐答案

在你的样品， rexponse.xhr.responseText 的值是一个字符串，而不是一个对象。您可以分析字符串转换为对象并访问 IMG 属性：

In your sample, the value of rexponse.xhr.responseText is a string, not an object. You can parse the string into an object and access the img property:

（JSON.parse（response.xhr.responseText））。IMG

...但是，由于悬浮窗成功活动获得文件对象，无论是解析的responseText ，你可以写一个成功处理程序是这样的：

...but, since Dropzone success events get both the file object and the parsed responseText, you could write a success handler like this:

new Dropzone("#myUploader", { 
    url: "/upload",
    init: function () {
      this.on("success", function (file, responseText) {
        console.log(responseText.img);
      });
    }
});
