Below we will design a scenario where the table grid needs to implement right-click, add, delete, and save operations on each row. For grid, I use gridview. I just use the styles provided by Microsoft. The test cases don’t need to be very beautiful. I’m not an artist anymore. Haha, I’m just lazy.
First, the renderings. Some comrades say that only with pictures can the truth be revealed:
ui code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits=" Default2" %>
< ;/title> <br><%-- --%> <br><script src="Script/jquery.js" type="text/javascript"></script> <br>< ;script src="Script/jquery.contextmenu.r2.js" type="text/javascript"></script> <br><style type="text/css"> <br>.SelectedRow <br>{ <br>background: yellow; <br>} <br>.contextMenu <br>{ <br>display: none; <br>} <br></style> <br><script type= "text/javascript"> <br>$(function() { <br>$('#GridView1 tr:gt(0)').contextMenu('menu', <br>{ <br>bindings: <br>{ <br>'add': function(t, target) { <br>alert('Trigger: 't.id' add' " taget by:" $("td:eq(0)", target). text()); <br>}, <br>'delete': function(t, target) { <br>alert('Trigger:' t.id ' delete' " taget by:" $("td:eq (0)", target).text()); <br>$(target).remove(); <br>}, <br>'save': function(t, target) { <br>alert(' Trigger: ' t.id ' Save ' " taget by:" $("td:eq(0)", target).text()); <br>}, <br>'About': function(t, target ) { <br>alert('Code by http://www.cnblogs.com/whitewolf/'); <br>} <br>}, <br>onShowMenu: function(e, menu) { <br>if (parseInt($("td:eq(0)", e.currentTarget).text()) > 10) { <br>$("#save", menu).remove(); <br>} <br>$(e.currentTarget).siblings().removeClass("SelectedRow").end().addClass("SelectedRow"); <br>return menu; <br>} <br>}); <br> }) <br></script> <br></head> <br><body> <br><form id="form1" runat="server"> <br><div> <br><div class="contextMenu" id="menu"> <br><ul> <br><li id="add"> <br><img src="image/Home_Age_UnSelect .jpg" width="16" height="16" /> <br>edit</li> <br><li id="delete"> <br><img src="image/Home_Age_UnSelect .jpg" width="16" height="16" /> <br>Delete</li> <br><li id="save"> <br><img src="image/Home_Age_UnSelect .jpg" width="16" height="16" /> <br>Save</li> <br><li id="About"> <br><img src="image/Home_Age_UnSelect .jpg" width="16" height="16" /> <br>About</li> <br></ul> <br></div> <br><asp:GridView ID ="GridView1" runat="server" Width="100%" BackColor="White" BorderColor="#CCCCCC" <BR>BorderStyle="None" BorderWidth="1px" CellPadding="3"> <br>< ;RowStyle ForeColor="#000066" /> <br><FooterStyle BackColor="White" ForeColor="#000066" /> <br><PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign= "Left" /> <br><SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <br><HeaderStyle BackColor="#006699" Font-Bold=" True" ForeColor="White" /> <br></asp:GridView> <br></div> <br></form> <br></body> <br></ html> <br>
</div> <br>Note: <br>1: contextMenu we hide some menu items based on data records. This can be done in the onShowMenu event, based on the <br>e.currentTarget trigger source to obtain data, based on remove menu item. For example, in the test case: if id>10, saving is not allowed <br>if (parseInt($("td:eq(0)", e.currentTarget).text()) > 10) { <br>$ ("#save", menu).remove(); <br>} <br>2: Event registration: Get data according to the second parameter target, and get the menu item according to the first parameter t. For example: <br><div class="codetitle">
<span><a style="CURSOR: pointer" data="84374" class="copybut" id="copybut84374" onclick="doCopy('code84374')"><u>Copy code </u></a></span> The code is as follows: </div>
<div class="codebody" id="code84374"> <br>'add': function(t, target) { <br>alert('Trigger: ' t.id ' increase ' " taget by:" $("td:eq(0)", target).text()); <br>}, <br>
</div>
<br>Ajax and server-side communication are needed here. You can use the component from my previous article: jQuery Ajax imitates the AjaxPro.Utility.RegisterTypeForAjax auxiliary method, which will make it easier to apply ajax communication. <br>There is a problem here in the source code I downloaded: <br>Originally, the currentTarget here is always undefined. <br><div class="codetitle">
<span><a style="CURSOR: pointer" data="62347" class="copybut" id="copybut62347" onclick="doCopy('code62347')"><u>Copy code </u></a></span> The code is as follows: </div>
<div class="codebody" id="code62347"> <br>if (!!cur.onShowMenu) menu = cur. onShowMenu(e, menu); <br>$.each(cur.bindings, function(id, func) { <br>$('#' id, menu).bind('click', function(e) { <br>hide(); <br>func(trigger, currentTarget); <br>}); <br>}); <br>
</div> <br>After I modified: <br><div class="codetitle">
<span> <a style="CURSOR: pointer" data="1868" class="copybut" id="copybut1868" onclick="doCopy('code1868')"><u>Copy code</u></a></span> The code is as follows:</div>
<div class="codebody" id="code1868"> <br>if (!!cur.onShowMenu) menu = cur.onShowMenu(e, menu); <br>$.each(cur.bindings, function(id, func) { <br>$('#' id, menu).bind('click', function(ev) { <br>hide(); <br> func(trigger, e.currentTarget); <br>}); <br>}); <br>
</div> <br>This way everything is normal. <br>There is very little content, everything is interrupted and ends here, over! <br>Attachment download: <a href="http://xiazai.jb51.net/201109/yuanma/contextMenu_jquery.rar" target="_blank">Demo</a></div><div class="nphpQianMsg"><div class="clear"></div></div><div class="nphpQianSheng"><span>Statement：</span><div>The content of this article is voluntarily contributed by netizens, and the copyright belongs to the original author.
