Drop Down Selected from If Statement?

EndEffect · Jul 11, 2005

I am attempting to automatically select an option from a javascript generated dropdown box upon returning to the page from error. I am passing javascript an ASP sessioned variable to perform the check.

When I check the one value against the other, I get a true, and my code should execute properly, but for some reason, enclosing the "selected" statement inside the "if" causes the statement to break.

Code follows:

Code:

for ( x = 0 ; x < ProdArrayCnt + 1 ; x++ ) {
     myEle = document.createElement("option");
     myEle.value = JSArrayProd[x][1];
     myEle.text = JSArrayProd[x][2];
     testvalue1 = JSArrayProd[x][1];
     testvalue2 = '<%= Session("prodbox") %>';
     if (testvalue1 == testvalue2){
          myEle.selected = true;
     }
     myEle.style.background = '#bfd8df';
     masterform.prodbox.add(myEle);
}

Can anyone tell me why the myEle.selected craps out? Any help would be greatly appreciated!

try this:

Code:

var selectThisOne;
for ( x = 0 ; x < ProdArrayCnt + 1 ; x++ ) {
     myEle = document.createElement("option");
     myEle.value = JSArrayProd[x][1];
     myEle.text = JSArrayProd[x][2];
     testvalue1 = JSArrayProd[x][1];
     testvalue2 = '<%= Session("prodbox") %>';
     if (testvalue1 == testvalue2){
          selectThisOne = x;
     }
     myEle.style.background = '#bfd8df';
     masterform.prodbox.add(myEle);
}
masterform.prodbox.selectedIndex = selectThisOne;

I tested this:
-----------------------------------
<html>
<head>
<script>
var sessionVar = 'value2';// your session variable value
var JSArrayProd = new Array();

JSArrayProd[0] = new Array();
JSArrayProd[0] = ['value1','text1'];
JSArrayProd[1] = new Array();
JSArrayProd[1] = ['value2','text2'];
JSArrayProd[2] = new Array();
JSArrayProd[2] = ['value3','text3'];
JSArrayProd[3] = new Array();
JSArrayProd[3] = ['value4','text4'];

function doSelect(){
for ( x = 0 ; x < JSArrayProd.length ; x++ ) {
myEle = document.createElement("option");
myEle.value = JSArrayProd[x][0];
myEle.text = JSArrayProd[x][1];
testvalue1 = JSArrayProd[x][0];
testvalue2 = sessionVar;
if (testvalue1 == testvalue2){
myEle.selected = true;
}
myEle.style.background = '#bfd8df';
masterform.prodbox.add(myEle);
}
}
</script>
</head>
<body onLoad="doSelect()">
<form name="masterform">
<select name="prodbox">
</select>
</form>
</body>
</html>
-----------------------------------
Works fine in IE but not in FireFox or Netscape. Those don't like the 'masterform.prodbox.add(myEle);' line. But it's basically what you have so yours should work in IE.
