jQuery - Define variables based on array values -

i m not sure if proper way of defining variables based on array values.

the getparameterbyname() function returns url parameters

var t = gettab();  var paramarray = {  'year' : 'y',  'condition' : 'c',  'sort' : 's' };  /*below vars defined $.each var y = getparameterbyname('y'); var c = getparameterbyname('c'); var s = getparameterbyname('s');  */  $.each(paramarray, function(key, value) {      //define y,c,s variables     var value = getparameterbyname(value);      console.log(value);//logs blank (nothing)      if(value != "")     {         $("#sort-filter-number").append('<button id="'+value+'" class="refresh refresh-'+key+' btn btn-info btn-sm">'+value+' <i class="fa fa-times"></i></button>');     }  });  tosort(y,c,s); //line 55 error : uncaught referenceerror: l not defined 

you can define variables on window object make global , can accessed anywhere.

demo:

var paramarray = {    'year': 'y',    'condition': 'c',    'sort': 's'  };    $.each(paramarray, function(key, value) {    //define y,c,s variables    window[value] = key + ' => ' + value;    // ^^^^^^^^^^      document.write(value + '<br />'); //logs blank (nothing)      if (value != "") {      $("#sort-filter-number").append('<button id="' + value + '" class="refresh refresh-' + key + ' btn btn-info btn-sm">' + value + ' <i class="fa fa-times"></i></button>');    }    });    document.write(y + '<br />' + c + '<br />' + s); // no error here
