Variable Undefined in Firefox but working in IE

[almac007]

Hi,

I am trying to fix up some code and have run into a problem. For some reason the line of code

var sizeQ = gid("q" + aq).length;

is not assigning a value when the page is loaded in firefox but in IE it works perfectly.

Please see the complete function below:

function testAnswers(aqNow,review,toClose){
	//alert("inside test answers");
   var listQa = gid("listQuestions").value;

   var arrListQa = listQa.split(",");
   var arrToClose = toClose.split(",");
   //alert("question answered ->"+arrListQa.length);
   //alert("array is " + listQa);

   if(listQa!="" && review != "true"){
	   //alert("inside first part");
		   for (var i=0; i < arrListQa.length; i++){
				 var aq = arrListQa[i];
				 alert("aq is " + aq);
				// gid("debug").innerHTML += aq+"<br>";
				 //if(aq != aqNow){

					var sizeQ = gid("q" + aq).length;
					
					alert("sizeQ is " + sizeQ);
					 
					 
				/*	 
					 var test = gid("q"+aq);
					 alert("test is" + test);
					 
					 var test2 = document.getElementById(test.length);
					 alert("VALUE: " + test2);
					 
					 var test3= document.getElementById(aq);
					 alert("test3 is" + test3);
					 
					 alert("does this work: " + gid("q" + aq).length);
					*/ 
					 
					 //gid("debug").innerHTML += sizeQ+"<br>";
					 //alert("question answered ->"+sizeQ);
					 var contQ = 0;
				     var contQA = 0;
						for (var j=0; j < sizeQ; j++)
							{
								typField = gid("q"+aq)[j].type;
								
								if (((typField == "radio" || typField == "checkbox")&& gid("q"+aq)[j].checked) || (typField == "text" && gid("q"+aq)[j].value != "")){	
									contQA ++;
								}
								name = gid("q"+aq)[j].name;
								
								if (name!=nameNow){
									nameNow = name; 
									contQ +=1;
									
									}
								
								//if(typField == "checkbox"){gid("debug").innerHTML +="[checkbox]"+gid("q"+aq)[j].checked + "<br>";}
								
								//gid("debug").innerHTML += name+"["+contQA + " - " + contQ+"]<br>";
								
							}
							
							
						if((contQA >= contQ) && (contQA != 0)){
							alert("inside control if statement");
							controlSeeMore(aq);							
						};
				 //}
		   }
   }

If anyone could help me out with this i would be very greatful.

Thanks in advace,

What is gid?

[almac007]

Hi Fang,

here is the code for the gid function:

var vrs=navigator.appVersion;
var IE=((vrs.indexOf("IE") > -1) || (vrs.indexOf("Mac") > -1));

function gid(v){
if ((vrs.indexOf("IE") > -1) || (vrs.indexOf("Mac") > -1) )return document.all[v];
else return document.getElementById(v);
}

You can safely use:

function gid(v){
return document.getElementById(v);
}

On the other hand make sure your elements have an id (not only a name, but an id)
