需要Javascript正则表达式帮助

Question

I have a string:

User_TimeStamp=20120712201112&email_id=ufe.test20@markit.com&resetCode=**uNcoHR9O3wAAB46xw**&reset=true

I tried and Googled a lot to get the highlighted text. Basically I want a JavaScript regex to get all characters in between resetCode= and &reset=true .

Any help regarding this is highly appreciated.

Thanks

Answer 1

Two ways:

1. Your regex should be resetCode=([^&]*)
2. Split the string on & then iterate through each string and split on = comparing the first string to resetCode and return the second string when you find it.

Answer 2

Try this code where you're looking for the resetCode variable

var resetCodeValue;
var s = window.location.split('&');
for(var k in s) { var pair = s[k].split('=');
   if (pair[0] == 'resetCode'){
      resetCodeValue = pair[1];
   }
}

Answer 3

You can do something more 'readable':

retrieveDesired = User_TimeStamp.split('=')[3].split('&')[0];

Answer 4

why not just use this handy function to get the value of resetCode

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
}
document.write(getUrlVars()["resetCode"]);
