You can pass HTML to jQuery and use it in the same way as if the element was on the DOM, for example with find():
您可以将 HTML 传递给 jQuery 并以与元素在 DOM 上相同的方式使用它，例如find()：
console.log( $(resultData).find('h2').text() );
If your HTML doesn't have a root element then you can wrap it like so:
如果您的 HTML 没有根元素，那么您可以像这样包装它：
resultData = '<div>' + resultData + '</div>';
console.log( $(resultData).find('h2').text() );

How about:
怎么样：
$(resultData).find('h2').text()
$(resultData).find('h2').text()
