多次替换为 javascript

multiple replaces with javascript

提问by Marwelln

In PHP, you do this to replace more then one value at a time.

在 PHP 中，您这样做是为了一次替换多个值。

<?php
$string = "i am the foobar";

$newstring = str_replace(array('i', 'the'), array('you', 'a'), $string);

echo $newstring;
?>

How do you do this in javascript?

你如何在javascript中做到这一点？

Use javascript's .replace()method, stringing multiple replace's together. ie:

使用javascript的.replace()方法，将多个替换串在一起。IE：

var somestring = "foo is an awesome foo bar foo foo"; //somestring lowercase
var replaced = somestring.replace(/foo/g, "bar").replace(/is/g, "or");
// replaced now contains: "bar or an awesome bar bar bar bar"
