Question

In my form, my checkbox elements’ name are onSite[].

I’ve made a simple JavaScript to check them with one click.

function checkAll(field)
{
for (i = 0; i < field.length; i++)
    field[i].checked = true ;
}

And in the HTML a button which calls the function.

<input type="button" name="CheckAll" value="All" onClick="checkAll(document.sharepage.onSite[])">

Unfortunately it doesn’t work because I’m making array of the checked elements, and the [] confuse my JS.
Do you know any solution to fix it?

Answer 1

Use square bracket notation when you need to access a property which has a name that includes special characters.

document.forms.sharepage.elements['onSite[]']
