javascript用数组全局替换 [英] javascript replace globally with array

问题描述

您可以使用数组进行替换:

You can use array for replacement:

var array = {"from1":"to1", "from2":"to2"}

for (var val in array)
    text = text.replace(array, array[val]);

但是如果你需要全局替换怎么办，即text = text.replace(/from/g, "to");

But what if you need to replace globally, ie text = text.replace(/from/g, "to");

数组非常大，所以如果我为每个变量写text = text.replace(...)"，脚本会占用很多空间.

Array is pretty big, so script will take a lot of space if I write "text = text.replace(...)" for every variable.

在这种情况下如何使用数组?"/from1/g":"to1" 不起作用.

How can you use array in that case? "/from1/g":"to1" does not working.

推荐答案

var array = {"from1":"to1", "from2":"to2"}

for (var val in array)
    text = text.replace(new RegExp(val, "g"), array[val]);

正如安迪所说，您可能必须使用像 this 这样的脚本来转义特殊字符一个.

As Andy said, you may have to escape the special characters using a script like this one.
