如何将jQuery元素选择应用于字符串变量

Question

我有一些html被提取到一个字符串var,并希望然后在该字符串上使用jQuery元素选择.这可能吗？

例如:

HTML:

<div class=message>
  This is a message. Click <a class=link id=link1 href=example.com>here</a>
</div>

jQuery的:

$('div.message').each(function(i, item) {
  myHtml = $(this).html();
  //select <a> tag attributes here
)};

因此,在这个例子中,我要提取id和href从<a>标签中myHtml.

谢谢

如果我理解正确,你在字符串变量中有HTML代码,并想在其中查询？

// Suppose you have your HTML in a variable str
var str = '<div class="message">This is a message. Click '
        + '<a class="link" id="link1" href="example.com">here</a></div>???????????????';

// You query the DOM fragment created by passing the string to jQuery function.
// $(<string>) - creates a DOM fragment (string must contain HTML)
var anchor = $('a', $(str));

// Then you can retrieve individual properties and/or contents:
var id = anchor.attr('id');
var href = anchor.attr('href');
var text = anchor.text();
