Remove <script> tags from a string along with the content between them
提问by barrettathome
I have looked and looked and looked but I couldn't find anything on this. So lets say I have this string...
我已经看了又看，但我找不到任何关于这个的东西。所以可以说我有这个字符串......
var str = '<script>blah blah blah</script><a>...</a><div>...</div><p>...</p>';
I need to strip out the script tags out of the string along with all the content between the tags. Once the script tag is stripped I need to append it to a textarea. How in the world do I do this with jQuery?
我需要从字符串中去除脚本标签以及标签之间的所有内容。一旦脚本标签被剥离，我需要将它附加到一个文本区域。我到底如何用 jQuery 做到这一点？
Any help would be much appreciated!
任何帮助将非常感激！

since nobody else is going to post a simple and reliably-working routine, i guess i will:
由于没有其他人会发布一个简单且可靠的例程，我想我会：
function noscript(strCode){
var html = $(strCode.bold());
html.find('script').remove();
return html.html();
}
alert( noscript("<script>blah blah blah</script><div>blah blah blah</div>") );
//shows: "<div>blah blah blah</div>"

Try this:-
试试这个：-
var str= "<script>blah blah blah</script><div>blah blah blah</div>";
var html = $(str.bold());
html.find('script').remove();

Like so:
像这样：
var div = $('<div>').html(str);
div.find('script').remove();
str = div.html();

Here is a fiddle ( https://jsfiddle.net/skoley/9dnmbj3d/) of the answers which works best taken from several other sources, credit goes to them.
这是从其他几个来源获得的最佳答案的小提琴（https://jsfiddle.net/skoley/9dnmbj3d/），归功于他们。
function noscript(strCode){
var html = $(strCode.italics());
html.find('script').remove();
return html.html();
}
function noscript_alt(str)
{
var div = $('<div>').html(str);
div.find('script').remove();
str = div.html();
return str;}
