getting the number of checkboxes

[ingernet]

Hi there, I need to get the number of checkboxes in a given form. Would I use something like this line below?

document.myFormName.element.checkbox.length

...Or is there another way to do this without looping throughout all the elements and counting them one at a time, manually?

Thanks!

Something like that. The following would be the number of elements in the form. The elements property is an array.

document.myFormName.elements.length

You must loop through that array and test the type of each element. Count the ones with a type of checkbox.

var nCkboxes = 0;
for(var i=0; i < document.myFormName.elements.length ; i++){
  if( document.myFormName.elements[i].type == "checkbox" ) {
    nCkboxes++;
  }
}
