用jQuery解析HTML字符串 [英] parse html string with jquery

问题描述

我有一个来自Ajax加载源的HTML字符串.在将HTML放入文档中之前，我想从该字符串中的对象(图像)中获取一些属性.

I have an HTML string from a Ajax loaded source. I would like to get some attributes from an object (image) in this string, before I put the HTML into the document.

我有类似的东西:

$.ajax({  
        url: uri+'?js',  
        success: function(data) { 
            var htmlCode = $(data).html();  

            $('#otherObject').html(data);
        }  
    });

如何从该HTML字符串获取属性(例如src)?

How can I get attributes (the src for example) from this HTML string?

推荐答案

我不确定100％，但不会

I'm not a 100% sure, but won't

$(data)

为该数据生成一个带有DOM的jquery对象，该对象未连接到任何地方?或者，如果已经将其解析为DOM，则可以只使用$(#myImg"，data)或任何适合您需要的选择器.

produce a jquery object with a DOM for that data, not connected anywhere? Or if it's already parsed as a DOM, you could just go $("#myImg", data), or whatever selector suits your needs.

编辑
重新阅读您的问题，看来您的数据"已经是一个DOM，这意味着您可以进行操作(假设DOM中只有一个img，否则您将需要一个更精确的选择器)

EDIT
Rereading your question it appears your 'data' is already a DOM, which means you could just go (assuming there's only an img in your DOM, otherwise you'll need a more precise selector)

$("img", data).attr ("src")

如果要访问src属性.如果您的数据只是文本，则可能可以做到

if you want to access the src-attribute. If your data is just text, it would probably work to do

$("img", $(data)).attr ("src")
