JAVASCRIPT: Program Quit because => Error: NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN:

pizzipie · 09-20-2013, 11:53 AM

Hi,

I have a long running program that has inexplicably quit running. I run Ubuntu 13.04 and jquery 1.7.js. I'll try a brief explanation first.

I generate a select list from a partial name submitted by form.

1. Enter partial name on form and submit.
2. Program produces select list of qualified names.
3. Pick option(name) from select list.
4. Program shows (used to) table of data for associated name.

The trouble is in the showing of the generated data. The data no longer shows up. I have tried running firebug on this and it is acting weird also. It starts to run and just quits.

For instance; Firebug just stopped when running my file 'load.js' no error shown - does not have console option listed like it usually does.

Any help solving this would be appreciated.

R.

Code:

// ===================== This is my 'load.js' file ===============================

$(document).ready(function() {
$(function() {
$('#getPartName').one('submit',function() { showValues(); return false; }); //.one is one time only, could be .bind
});
function showValues() {
var searchName=$('#partnm').val();
//alert(typeof searchName);
if(typeof(searchName)=="string" & searchName=="") searchName="All Names";
var str = $("#getPartName").serialize();
//alert(typeof str, str);
$(".results-box").fadeIn();
$(".results").html("Result of Name Search for <span style='color:red;'>"
+ searchName + "</span> : Click on Your Choice for Data");
$(".results").append('<div id="addrsNames"></div>')
//.children("#addrsNames").hide()
.load("makeSelectList.php #addrsNames", str , function() { //
//$("#partname").remove();
$("#addrsNames").show(); //.slideDown("slow");
addSelectChange();
}); // function
} //show values
}); // doc ready

// ================ function addSelectChange() ==================================

function addSelectChange(){
$('select').one('change', function(){
var mySelection= $("option:selected", this).val();
//alert("my selection", typeof mySelection, mySelection);
if(mySelection) {
window.location.href="ContactInit.html?Display_Name="+ encodeURIComponent(mySelection);
}else {
alert(" Bad Search, Check names, first and last.");
}
});}

// ========================= End load.js ==============================================

Your load.js is physically painful to read. May I suggest paying some attention to issues such as indenting?

Sorry about that, just got in a hurry after long hours of frustration!

Code:

$(document).ready(function() {

		function showValues() {

			if(typeof(searchName)=="string" & searchName=="") searchName="All Names";	 	
   			
			var str = $("#getPartName").serialize();
			    	
			$(".results-box").fadeIn();

			$(".results").html("Result of Name Search for <span style='color:red;'>" + searchName + "</span> :  Click on Your Choice for Data");

			$(".results").append('<div id="addrsNames"></div>')
			
			.load("makeSelectList.php #addrsNames", str , function() {       
				$("#addrsNames").show(); 
				addSelectChange();
			}); // end load
  
		 } // end showvalues
				
}); // end docready
		
// ======================= function addSelectChange() ========================

function addSelectChange(){
