使用ASCII码在JavaScript中转义字符

Question

I am creating a bookmarklet and I have to avoid using double quotes ( " ) because I have to include the bookmarklet inside a HTML page and it's inside a string that uses double quotes:

<a href="javascript:...">

In some places I have to use the code replace(/".*/, '');

In sed, I can escape double quotes using \\x22 (22 is the ASCII hex code for double quotes)

Is it possible to do something similar in JavaScript like replace(/\\x22.*/, ''); ?

Answer 1

You can use the other syntax for making a RegExp and use String.fromCharCode

Here's an example:

'"hello"'.replace(new RegExp(String.fromCharCode(34), 'g'), '-quotes-')

-->

'-quotes-hello-quotes-'

Answer 2

The same way you would use quotes in any HTML attribute's value.

example

<img src="..." alt="A picture of Bob &quote;Wild Man&quot; Johnson">

so for you

<a href="javascript:replace(/&quot;.*/, '');">
