Remove HTML Tags From A String, Using jQuery
提问by moey
I have a simple string e.g.
我有一个简单的字符串，例如
var s = "<p>Hello World!</p><p>By Mars</p>";
How do I convert sto a jQuery object? My objective is to remove the <p>s and </p>s. I could have done this using regex, but that's rather not recommended.
如何转换s为 jQuery 对象？我的目标是删除<p>s 和</p>s。我本可以使用正则表达式完成此操作，但不推荐这样做。

In the simplest form (if I am understanding correctly):
以最简单的形式（如果我理解正确的话）：
var s = "<p>Hello World!</p><p>By Mars</p>";
var o = $(s);
var text = o.text();
Or you could use a conditional selector with a search context:
或者您可以使用带有搜索上下文的条件选择器：
// load string as object, wrapped in an outer container to use for search context
var o = $("<div><p>Hello World!</p><p>By Mars</p></div>");
// sets the context to only look within o; otherwise, this will return all P tags
var tags = $("P", o);
tags.each(function(){
var tag = $(this); // get a jQuery object for the tag
// do something with the contents of the tag
});
If you are parsing large amounts of HTML (for example, interpreting the results of a screen scrape), use a server-side HTML parsing library, not jQuery (tons of posts on here about HTML parsing).
如果您要解析大量 HTML（例如，解释屏幕抓取的结果），请使用服务器端 HTML 解析库，而不是 jQuery（这里有大量关于 HTML 解析的帖子）。

To get all the strings there use
要获取那里的所有字符串，请使用
var s = "<p>Hello World!</p><p>By Mars</p>";
var result = "";
$.each($(s), function(i){
result += " " + $(this).html();
});

if you don't want regex, why don't u just:
如果你不想要正则表达式，你为什么不：
var s = "<p>Hello World!</p><p>By Mars</p>";
s = s.replace('<p>', '').replace('</p>', '');
