jqgrid - 扩展 addRowData

Question

感谢 Oleg，我有了在网格中任意位置添加一行的解决方案。但我想要这个功能

• 不当inlineNav 中有"Add" 链接时
• 但是当我点击 jqgrid caption - MY JQGRID

有可能吗？

HTML

<table id="myjqgrid"></table>
<div id="pager"></div>  

JQGRID

$(document).ready(function () {
    var oldAddRowData = $.fn.jqGrid.addRowData;
    var mydata = [
        { id: "1",  invdate: "2007-10-01", name: "test",   note: "note",   amount: "200.00", tax: "10.00", closed: true,  ship_via: "TN", total: "210.00" },

您如何理解您希望将事件处理程序绑定到单击网格标题的问题。例如here 描述了网格元素的结构。所以你可以通过下面的选择器只选择网格的捕获

#gview_myjqgrid>div.ui-jqgrid-titlebar

并绑定您需要的任何事件处理程序。例如

$('#gview_' + $.jgrid.jqID($grid[0].id) + '>div.ui-jqgrid-titlebar').click(function () {
    alert("The caption (the titlebar) is clicked");
});

尽管如此，我不建议您实现在点击捕获标题时添加新行。问题是操作系统和不同软件中使用的许多现代 GUI 的强大之处在于标准用户界面。所以用户不需要研究用户需要使用的每一个新程序。例如，它为培训节省了大量资金，并允许在从互联网上购买和下载后立即使用程序。所以如果客户有这样的需求，可以和客户再讨论一次，建议直接在捕获中插入添加按钮。它将允许新用户猜测您实现的功能，而无需任何培训。
