Javascript error: TypeError: 'null' is not an object (evaluating 'event.target') on safari

Question

I have difficulty on integrating my JavaScript syntax. My code is working on Internet Explorer (IE). However, I encountered a JavaScript error when running it on Safari.

Answer 1

As Bhojendra mentioned don't use srcElement. Check for object null or not before accessing id or target property as below.

document.onmouseup = function hideaddrspopup () 
{   

if (e && e.target && e.target.id!='fieldName')
  {   
    alert(e.target.id);
  }
else if(e && e.srcElement && e.srcElement.id!='fieldName')
  {
    alert(e.srcElement.id);
  }
}

Updated with else if to support older IE browser. target should support it too but you could test without else part if it is necessary or not.
