Javascript window.onload not firing in Firefox

Hi Experts -

I have the following code set up to repopulate some product filters that I am storing so that when the user presses the back button or refreshes the screen, the filters are saved.

The code works perfectly in IE when I press the back button or rerfresh the page, the filters are restored.

In firefox this only fires if I refresh the page. If I press the back button, the javascript never fires.

This may not be the best way to do  this. I am open to suggestions if there is a better way to program the javascript.

Thank you!


<script type="text/javascript">

function loadProducts(type,category)
{
      var brand = [];
	  var color = [];
	  var price = [];
	  var capacity = [];
	  var width = [];
	  var val = [];
	  var COOKINGTYPE = [];
	  var POWERSOURCE = [];
	  var BURNERTYPE = [];
	  var SURFACETYPE = [];
	  var COOKINGSURFACE = [];
	  var CLEANINGTYPE = [];
	  var SHELVING = [];
	  var MOTORSPEEDS = [];
	  var HORSEPOWER = [];
	  var TYPEFEED = [];
	  var TUBMATERIAL = [];
	  var CONTROLTYPE = [];
	  var WASHLEVELS = [];
	  
	  
	Url = "products_filter.php?Category="+category+"&Available=1&Search.x=50&Search.y=8";
	Datas = $("#frm").serialize();
	$.ajax({
		url:Url,
		type:'POST',
		data:Datas,
		beforeSend: function ()
		{                               
			$("#product").html("Please wait...");                                               
		},
		success:function(msg)
		{                     
			$("#product").html(msg);                 
		}                   
	   });

}

function nav_ajax(page)
{
    var type='price';
	//$.post(page,{},function(data) { $("#content").html(data);});
	 var brand = [];
	  var color = [];
	  var price = [];
	  var capacity = [];
	  var width = [];
	  var val = [];
	  var filters = [];
  
	
	Url = page;
	Datas = $("#frm").serialize();
	$.ajax({
		url:Url,
		type:'POST',
		data:Datas,
		beforeSend: function ()
		{                               
			$("#product").html("Please wait...");                                               
		},
		success:function(msg)
		{                     
			$("#product").html(msg);                 
		}                   
	   });

// for Mozilla browsers

if (document.addEventListener) {
  document.addEventListener("DOMContentLoaded", init, false);
}

--  since you using jQuery - i would add this in your document.ready

<script type="text/javascript">                                        
   $(document).ready(function() {
        
// for Mozilla browsers

if (document.addEventListener) {
  document.addEventListener("DOMContentLoaded", init, false);
}      

   });
</script>

Sorry - I am not very familiar with Javascript.  Should I just copy and past this above the code I have hear or does it go in the head tags?

I pasted your code in to the head tag but it did not help.

you can try to replace all your instance of window.onload
such as:
 window.onload=your_function;

to
if (window.attachEvent)
  {window.attachEvent('onload', your_function);}
else if (window.addEventListener)
  {window.addEventListener('load', your_function, false);}
else
  {document.addEventListener('load', your_function, false);}

 i know it's longer but it will take care all the browser for you

something like this if you not clear

replace this
      window.onload = function(){loadProducts('brand');};

with this      

if (window.attachEvent)
      {
                  window.attachEvent('onload', loadProducts('brand') );
      }
      else if (window.addEventListener)
            {
                  window.addEventListener('load',loadProducts('brand'), false);
            }
      else {
            document.addEventListener('load', loadProducts('brand'), false);
      }

the following code works in between <body> ... </body> in Edge/Firefox/Chrome
but when I moved them into a javascript.js file it does not... not happening if not after the load time.. back to the problem again. Catch-22

<script>

if (window.attachEvent)
{
    window.attachEvent('onload', loadMyEvents() );
}
else if (window.addEventListener)
{
    window.addEventListener('load',loadMyEvents(), false);
}
else
{
    document.addEventListener('load', loadMyEvents(), false);
}
 
function loadMyEvents()
{
    document.getElementById("myname").onfocus = function(){doOnFocus(this)};
    document.getElementById("optin").onclick = function(){doOnClick(this)};
    document.getElementById("myname").onblur = function(){doOnBlur(this)}
    document.getElementById("mydirection").onchange = function(){doOnChange(this)};
    document.getElementById("myform").onsubmit = function(){return doOnSubmit(this)};
    document.getElementById("windowsBody").onload = function(){doOnLoad()};
    document.getElementById("mylink").onclick = function(){doOnClick(this)};
    document.getElementById("mypara").onmouseover = function(){doOnMouseOver(this)};
    document.getElementById("mypara").onmouseout = function(){doOnMouseOut(this)};
}    
</script>

What is the trick to make the function only works after the onload in an external js file.

The following worked on all three browers (Chrome, Firefox, Edge): (I try not to use any jQuery):

window.onload = function() {myFunction()};
 
function myFunction()
{
    doOnLoad();
    document.getElementById("myname").onfocus = function(){doOnFocus(this)};
    document.getElementById("optin").onclick = function(){doOnClick(this)};
    document.getElementById("myname").onblur = function(){doOnBlur(this)}
    document.getElementById("mydirection").onchange = function(){doOnChange(this)};
    document.getElementById("myform").onsubmit = function(){return doOnSubmit(this)};
    document.getElementById("mylink").onclick = function(){doOnClick(this)};
    document.getElementById("mypara").onmouseover = function(){doOnMouseOver(this)};
    document.getElementById("mypara").onmouseout = function(){doOnMouseOut(this)};
}
