get js file query param from inside it
- by vsync
I load this file with some query param like this:
src='somefile.js?userId=123'
I wrote the below function in 'somefile.js' file that reads the 'userId' query param
but I feel this is not the best approach. Frankly, its quite ugly. Is there a better way?
function getId(){
var scripts = document.getElementsByTagName('script'), script;
for(var i in scripts){
if( scripts.hasOwnProperty(i) && scripts[i].src.indexOf('somefile.js') != -1 )
var script = scripts[i];
}
var s = (script.getAttribute.length !== undefined) ?
script.getAttribute('src') :
script.getAttribute('src', 2);
return getQueryParams('userId',s);
};
