使用javascript解析html字符串

Question

I want to extract part of html string which format is given as below. This html string is returned by var contents = $("#content").html()

blah1 blah1
<p> blah2 blah2 </p>

Then I use

start = contents.indexOf("<p>");
end = contents.indexOf("</p>");

to get the start and end positions. So I can use contents.slice(start, end) to extract the string I want.

But in IE browser the <p> tag is capital <P> and in Chrome and Firefox, they user <p>

How can I include both cases so that my JavaScript function can work in all browsers? Thanks

Answer 1

您可以使用：

$('#content p').text();

Answer 2

Why not just grab the innerHTML of the p tag in question?

jQuery:

var contents = $("#content > p").html();

or even, just the plain text:

var contents = $("#content > p").text();
