What's wrong with this javascript code?

var act = false;
var newprod开发者_Go百科 = prompt("tell me somthing", "");

if (newprod != '' && newprod != null) {
  $.ajax({
    //posting code here
  });
}

if (act != false) { document.location.href = window.location; }

The page is refresh in every condition even act false or not.

It is fired on an event.

Can anyone tell me why it page is refreshed in all condition?

var act = false;
var newprod = prompt("tell me somthing", "");

if (newprod) { // not null, undefined or 0
  $.ajax({
    //posting code here
  });
}

if (act) { window.location.reload(1); }

assuming that is what the code was supposed to do. document.location is deprecated and in theory read-only.

This should work

if( newprod != null && newproda.length != 0) {

 //Execute the code

}

To the reason why it was always working was that newprod was not the same as ''.

As the question is what is wrong with that JavaScript code i will advise.

if(act) {
 document.location.href = window.location;
}

You may want to learn more about false-y values in JavaScript. My guess is that your if statement is giving you some problems because it does not compare the way you think it should compare.
