Can some one convert following code to jQuery ?

function check(value)
{
        x = document.bulk_import.elements.length;
        for(i=0;i<x;i++)
    {
                if(document.bulk_import.elements[i].name == 'article_id[]')
        {
                        document.bulk_import.elements[i].checked = value;
                }
        }
}

The function is used to check/uncheck all check box.
