插件中的参数说明:
Parametersmenu_idThe id of the menu as defined in your markup. You can bind one or more elements to a menu. Eg $("table td").contextMenu("myMenu") will bind the menu with id "myMenu" to all table cells. Note: This behaviour has changed from r1 where you needed a "#" before the id settingsContextMenu takes an optional settings object that lets you style your menu and bind click handlers to each option. ContextMenu supports the following properties in the settings object: bindings An object containing "id":function pairs. The supplied function is the action to be performed when the associated item is clicked. The element that triggered the current menu is passed to this handler as the first parameter. Note: This behaviour has changed from r1 where you needed a "#" before the id menuStyle An object containing styleName:value pairs for styling the containing <ul> menu. itemStyle An object containing styleName:value pairs for styling the <li> elements. itemHoverStyle An object containing styleName:value pairs for styling the hover behaviour of <li> elements. shadow Boolean: display a basic drop shadow on the menu. Defaults to true eventPosX Allows you to define which click event is used to determine where to place the menu. There are possibly times (particularly in IE6) where you will need to set this to "clientX". Defaults to: 'pageX' eventPosY Allows you to define which click event is used to determine where to place the menu. There are possibly times (particularly in IE6) where you will need to set this to "clientY". Defaults to: 'pageY' onContextMenu(event) A custom event function which runs before the context menu is displayed. If the function returns false the menu is not displayed. This allows you to attach the context menu to a large block element (or the entire document) and then filter on right click whether or not the context menu should be shown. onShowMenu(event, menu) A custom event function which runs before the menu is displayed. It is passed a reference to the menu element and allows you to manipulate the output before the menu is shown. This allows you to hide/show options or anything else you can think of before showing the context menu to the user. This function must return the menu. 通过此插件可以在不同的html元素内建立contextmenu,并且可以自定义样式.

关于JQuery的serialize方法.让我崩溃一天的问题解决了
这几天做一个Ajax像服务器动态提交的表单然后给出即时反馈.这些表单内容都是一系列的.内容大同小异.所以代码和页面结构也是大同小异.但是其中有一个页面使用AJAX始终无法提取到服务器值.反而将此页的整个render出来的页面显示出来.关键代码如下:
$(document).ready(function() {
$("#Submit").click(function() {
var a = $("#aspnetForm").serialize();
/*因为使用了masterpage,所以页面form的ID为aspnetForm*/
$.ajax({
url: "xxx.aspx",
type: "get",
data: a,
success: function(data){
$("#result").html(data);
}
});
});
});
后台代码简略如下.只是为了让大家明白意思:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["length"] != null)
{
Response.Clear();
Response.Write("这里是回传的数据");
Response.End();
}
}
