Question

I have a table with checkboxes in the first column. I use the jQuery DataTable plugin display my table.

I made 2 links to select/unselect every checkboxes. Here’s the one to select all :

<a href="" name="CheckAll" onClick="checkAll(document.email_list_form_inviter.getElementsByClassName(\'email_checkbox\'), event)" >Select all</a>

And the javascript :

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

    return false;
}

But the datatable enables pagination and my function select only the visible checkboxes, not those of the other pages. How can do to select every checkboxes in my data table?

Solution :

Ok I did this with fnGetNodes, thank you amccausl!

$("a[name='CheckAll']").click(function(event) {
        event.preventDefault();
        var nodes = datatable.fnGetNodes( );
        $('.email_checkbox', nodes).attr("checked", "checked");
    });

Answer 1

You can use fnGetNodes to grab all the nodes you need, instead of the getElementsByClassName.

You should also be using jquery.click() event instead of defining an onClick yourself
