// create by tony on 2009-04-22
// eg: $("#id").jsRightMenu({
// menuList:[{ menuName: "右键菜单", clickEvent: "divClick('click1')"}]
// });
jQuery.fn.extend({
jsRightMenu: function(options) {
options = $.extend({
menuList: []
}, options);
return this.each(function() {
if ($("#div_RightMenu", $(this)).size() == 0) {

var event = arguments[0] || window.event;
var clientX = event.clientX;
var clientY = event.clientY;
var redge = document.body.clientWidth - clientX;

if (objMenu.size() > 0) objMenu.hide();
}
});
}
});
三:html
<div id="divTest">右键菜单显示区域</div>
四:使用
首先去JQuery的官方网站下载最新版本：http://jquery.com/，然后在页面的<head></head>之间加入下面代码：
<script src="../js/jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$("#divTest" ).jsRightMenu({
menuList: [{ menuName: "右键菜单1", clickEvent: "divClick('1')"},
{ menuName: "右键菜单2", clickEvent: "divClick('2')"},
{ menuName: "右键菜单3", clickEvent: "divClick('3')"},
{ menuName: "右键菜单4", clickEvent: "divClick('4')"},
{ menuName: "右键菜单5", clickEvent: "divClick('5')"}
]
});
});
function divClick(id){
alert("你点了--右键菜单"+id);
}
</script>
OK
