Question

I have a div with ID ‘adpictureholder’, to which I dynamically add (or remove) images.
On Form submit I want to get SRC values of all these images within that DIV and put them to the value of one hidden input with ID ‘piclinkslisttosubmit’.
The thing is that my current Javascript does not function as if there is some syntax typo there, but I don’t see where.
Can anyone please have a quick look at it?

function copyonsubmit(){
    var strump1 = '';
    var i=0;
    var endi = document.getElementById('adpictureholder').childNodes[].length - 1;
    var images = document.getElementById('adpictureholder').childNodes[];
    for (i=0;i<=endi;i++)
    {
        strump1 = strump1 + '|' + images[i].src;
    } 
    document.getElementById('piclinkslisttosubmit').value = strump1;
}   

Answer 1

Change childNodes[] to simply childNodes.

You don’t need to specify that a variable you’re referencing is an array by adding brackets.
