read parameter on js file [duplicate]

Pass vars to JavaScript via the SRC attribute

May I know how to read get the p value on js file link like filename.js?p=value with local javascript in the js file? Any function to work like the $_GET['p'] in php? Thanks.

This just tells you (in a very convoluted manner) how to use window.location.search to extract the query string from the current request url. But that is completely different than a query string to a javascript file. — Ben Lee

@BenLee it is a completely different question. One is pass by variable, this is pass by link's parameter. Pls read the question again Ben. Thanks. — davidlee

@davidlee Look again at the non-accepted answers to that question: they show how to get query parameters from the URL used to load the script. — Richard

try this:

var tmp = location.href, it;
if (q) it = tmp.substr(q + 1).split('&');
else it = '';
for (var i in it) {
    var t = it[i].split('=');
    if (t[0] == 'p') {
        //do something
        break;
    }
}

and what is wrong with this one?

Not the one to downvote, but let me explain what is wrong: window.location point to the location of the document that loaded the current script. OP wants to extract the query string of the script file itself (as loaded from the HTML document).

function _GET( name )
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return results[1];
}

This will do the equivalent in javascript.
