Question

http://www.domainname.com/#changepassword

I need to pass an extra variable with a URL like above.

I’ve tried a few ways but I’m unsure of the best way to do this eg:

http://www.domainname.com/#changepassword?variable

I’m using the following JQUERY to catch the HASH:

if (window.location.hash != '') {
    var hash = window.location.hash.substring(1);
    if(hash == 'changepassword') {      // Password Change
        alert('changepassword');
    }
}

How can I pass an extra variable with the HASH? Best method to capture the HASH and extra variable.

thx

Answer 1

You are mixing the location.hash with location.search – see here for the explanation

You could use just the location.hash and put a seperator between your “variables” :

For example .. if this was your url http://www.domainname.com/#changepassword-variable-another then you could do

var hash = window.location.hash.substring(1);
var hasharray = hash.split['-']
if(hasharray[0] == 'changepassword') {      // Password Change
    alert('changepassword');
}

or you could use the location.search and the following example :

URL : http://www.domainname.com/?command=changepassword&var=variable&var2=another

this uses the key=value format, then use the following method to access the values

function getQueryString() {
  var result = {}, queryString = location.search.substring(1),
      re = /([^&=]+)=([^&]*)/g, m;

  while (m = re.exec(queryString)) {
    result[decodeURIComponent(m[1])] = decodeURIComponent(m[2]);
  }

  return result;
}

You can then get the values by passing the function your key

var command = getQueryString()["command"];
if(command == 'changepassword') {      // Password Change
    alert('changepassword');
}
