how to check the state of a checkbox

[lcscne]

My bad, disregard this message, my problem was elsewhere.

for (i=0; i<document.frmStudentList.elements.length; i++)
{
if(document.frmStudentList.elements[i].type == "checkbox")
{
if(document.frmStudentList.elements[i].checked)
.....

I'm trying to check the state of checkbox so I can perform action. However I'm getting "Invalid Argument" on the second if statement. Any suggestions on how to check the state of a checkbox while in an array like this?

that could be due to the fact that the element you are trying to access "checked" property of, does not realy have that property,which means you are trying to access "checked" property for buttons other then radio and checkbox buttons

Take a look at the code (http://forums.webdeveloper.com/showthread.php?s=&threadid=18751#post98873) I gave you. I needed to do that in that little snippet...

Hint: it's this part (document.myform.elements[i].type == "checkbox") which can be evaluated as such:

if (document.myform.elements[i].type == "checkbox") {
//do something -- the element is a checkbox
}
else {
//do something else -- the element is not a checkbox
}
