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);
});
}
});
