如何用`replace`方法用相应的关键字替换多个关键字? [英] How to replace multiple keywords by corresponding keywords with the `replace` method?

问题描述

我想制作一个内容可编辑的div，在其中用星号替换显式单词.这是我的JavaScript代码:

I want to make a content editable div in which I replace explicit words with asterisks. This is my JavaScript code:

function censorText(){
    var explicit = document.getElementById("textbox").innerHTML;
    var clean = explicit.replace(/"badtext1","cleantext1"|"badtext2","cleantext2"/);
    document.getElementById("textbox").innerHTML = clean;
}

这是我的< div contenteditable> 的HTML:

<div contenteditable="true" onkeyup="censorText()" id="textbox">Hello!</div>

如您所见，我尝试使用正则表达式运算符一次替换多个字符串，但是它不起作用.它不会将 badtext2 替换为 cleantext2 ，而是将 badtext1 替换为 0 .如何使单个 .replace()语句替换多个字符串?

As you can see, I tried using a regex operator to replace multiple strings at once, but it doesn’t work. It doesn’t replace badtext2 with cleantext2, and it replaces badtext1 with 0. How can I make a single .replace() statement replace multiple strings?

推荐答案

使用/.../g 表示全局替换.

var clean = explicit.replace(/badtext1/g,"cleantext2"/).replace(/cleantext1/g,"cleantext2"/).replace(/badtext2/g,"cleantext2"/);
