我有一个字符串如下:如何从Javascript字符串中删除特定的“序列”?

Well, here we are.^2000 Ain't much to look at, is it?^2000 Came here on a Wednesday night once.^1000 It was actually pretty crowded.^1000 But on a Tuesday evening .^300 .^300 .^1000 I guess it's just you^1000 and me.^3000 Heh. 

现在我不知道我怎么会删除随后的^所以它最终将输出以下,

Well, here we are. Ain't much to look at, is it? Came here on a Wednesday night once. It was actually pretty crowded. But on a Tuesday evening . . . I guess it's just you and me. Heh.

你想使用[Regex](http://www.regular-expressions.info/tutorial.html)。 – Jhecht

使用此:

var res = str.replace(new RegExp("(\\^\\d+)","gm"), ""); 

哪里str是字符串,正则表达式匹配^<number>和更换字符串""

毕竟^和数字正如我在评论中所说的,你想使用一种叫做Regex的东西。

$(document).ready(function() { 
 

 
    var html = $('#start').html(); 
 

 
    var output = html.replace(/(\^\d{2,4})/g, ''); 
 

 
    $('#results').html(output); 
 

 

 
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div id="start"> 
 
    Well, here we are.^2000 Ain't much to look at, is it?^2000 Came here on a Wednesday night once.^1000 It was actually pretty crowded.^1000 But on a Tuesday evening .^300 .^300 .^1000 I guess it's just you^1000 and me.^3000 Heh. 
 
</div> 
 
<div id="results"> 
 
</div>
