匹配 @(\w+) 并在 javascript 中替换 [英] Match @(\w+) and replace in javascript

问题描述

我正在尝试匹配 div 内容中的 @(\w+) 并将其删除.

这是我尝试过的:http://jsfiddle.net/mxgde6m7/1/.

@(\w+) 有效，但它不会替换为空格.

var content = document.getElementById('contentbox');var find = '@(\w+)';var reg = new RegExp(find, 'g');var 结果 = content.innerHTML.replace(reg, ' ');警报(结果)；<div id="contentbox">@d <a href="#" id="5">test </a>

我想要的是:<div id="contentbox"><a href="#" id="5">test </a>

提前致谢.

编辑

好的，一个问题解决了，另一个问题又来了.我的脚本 http://jsfiddle.net/mxgde6m7/9/ 在那里完美运行，但是当我尝试它在我的网站上，只有一半有效.应该用空格替换 @(\w+) 的最后一部分根本不起作用.如果我在控制台(chrome)中复制/粘贴函数的内容，它会起作用，但是如果我粘贴该函数并调用它，则它不起作用.

请帮忙！我被卡住了.

解决方案

使用 RegExp 构造函数，您需要两个反斜杠 \\ 代替每个反斜杠 \.

var find = '@(\\w+)';

I'm trying to match @(\w+) in a div content and remove it.

Here's what i've tried : http://jsfiddle.net/mxgde6m7/1/ .

@(\w+) works , but it doesn't replace with space.

var content = document.getElementById('contentbox');
    var find = '@(\w+)';
    var reg = new RegExp(find, 'g');
    var result = content.innerHTML.replace(reg, ' ');
    alert(result);

<div id="contentbox">@d <a href="#" id="5">test </a>

What i want: <div id="contentbox"><a href="#" id="5">test </a> </div>

Thanks in advance.

EDIT

Okay, one problem solved, another one came up. My script http://jsfiddle.net/mxgde6m7/9/ works perfectly there, but when i try it on my website, only a half works. The last part where it should replace @(\w+) with space doesn't work at all. If i copy/paste the CONTENT of the function in console(chrome), it works , but if i paste the function and i call it, it doesn't work.

Please help ! I'm stuck.

解决方案

Using a RegExp constructor, you need two backslashes \\ in place of each backslash \.

var find = '@(\\w+)';
