Js特效总结

1、//#hidediv2为一个需要隐藏的div  这个功能实现当点击hidediv2以外的其他任何位置时，隐藏该div   

$(document).click(function() {
            try {
                var _event = event ? event : window.event;
                var _target = _event.target ? _event.target : _event.srcElement;
                var _id = _target.id;
                if (_id == '') {
                    $("#hidediv2").hide(100);
                }
            }
            catch (eee) { }
        })

2、//asp.net gridview中checkbox的全选功能

 function CheckAll() {
            if (a == 1) {
                for (var i = 0; i < window.document.form1.elements.length; i++) {
                    var e = form1.elements[i];
                    e.checked = false;
                }
                a = 0;
            }
            else {
                for (var i = 0; i < window.document.form1.elements.length; i++) {
                    var e = form1.elements[i];
                    e.checked = true;
                }
                a = 1;
            }
        }
