解析来自jQuery ajax表单post的响应。

I am successfully posting a form via ajax, using the following code;

我正在使用以下代码通过ajax成功发布表单;

 $.post( "Page.do?source=ajax", 
            $("#Form").serialize(), 
            function(data){ 


                }

The data response that comes back can be alert'd. I can see that it is the HTML of the entire form, having been submitted. But, I am having trouble accessing an element in that form which has come via ajax, ie

返回的数据响应可以是警报。我可以看到它是整个表单的HTML，已经提交。但是，我无法访问通过ajax获得的那种形式的元素

data.find('.Errors').html()

或

$('.Errors', data).html()

Do I need to somehow convert the text into a DOM which can then be parsed by jQuery?

我是否需要以某种方式将文本转换为DOM，然后由jQuery解析?

Correct, otherwise you would have to apply regex to the result (which is a string and not a DOM).

正确，否则您必须将regex应用到结果(它是一个字符串，而不是DOM)。

You can convert it to DOM by:

您可以将其转换为DOM:

$(data)

and then applying any jQuery you want to it.

然后应用你想要的jQuery。

Yes you do:

是的,你做的事:

$(data).find('.Errors').html();

美元(数据);(' . error '). html();

Although normally using data as the scope for the selector like you showed in your second example should work.

尽管通常使用数据作为选择器的范围，如您在第二个示例中所显示的那样，应该可以工作。
