javascript用数组替换全局 [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，即
text = text.replace（/ from / g，to）;

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

数组相当大，所以如果我写text = text.replace（...），脚本会占用大量空间）对于每个变量。

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]);

编辑：正如Andy所说，你可能不得不使用像这一个。

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