Question

I’m trying to use regExp to read URL parameters. I need to perform a Match on the following string :

SomeMoreText&action='{%22JsonParameter%22:[%221234%22]}'&SomeMoreText

The end result should be

                         '{%22JsonParameter%22:[%221234%22]}'

I’m gessing I need an expression to find everything between &action= and the following &. I tried different expressions with no success and, to be honest, I’m having a lot of difficulty understanding regular expression syntax. The problem here is the colon, quotes (%22) and brackets I think. If it was only text, I believe something like this would work :

/action=([\w\-]+)/

Can anyone help?

Thanks

How ’bout

var m = /action=([^&]+)/.exec(str);
if (m) {
    // The content is in m[1]
}
