如何读取JQgrid行值

时间：2014-10-31 10:28:31

标签： jquery jqgrid

我正在研究Jqgrid试图在上下文菜单点击事件中获取行值，但我无法得到它。这是我试图用来获取行值而不是成功的代码.. < / p> 

loadComplete: function () {
 $("tr", this).contextMenu('myMenu1', {
 bindings: {
 'Reservation': function (trigger) {   
  var rowData = $(this).jqGrid('getRowData', trigger.id);
  var coldata = rowData.RoomNo;
  alert(coldata);
  addTab('Reservation', '');
 }

请帮我纠正错误。谢谢..

这是我的HTML .. 

<div class="contextMenu" id="myMenu1" style="display:none; width:auto;">
    <ul style="width: 200px;">
     <li id="Reservation">
            <span class="ui-icon ui-icon-pencil" style="float:left"></span>
            <span style="font-size:11px; font-family:Verdana">Reservation</span>
        </li>
</ul>
</div>

在我看来，主要问题是使用$(this)。您应该将$(this)的值保存在loadComplete内的变量中，然后在Reservation回调中使用它。代码可能类似于以下

loadComplete: function () {
    var $self = $(this); // save `this`

    $self.find(">tbody>tr.jqgrow").contextMenu("myMenu1", {
        bindings: {
           Reservation: function (trigger) {
               var rowData = $self.jqGrid("getRowData", trigger.id);
               var coldata = rowData.RoomNo;
               alert(coldata);
           }
        }
    });
}

更新：要为上下文菜单设置width: 200px，请使用menuStyle: {width: "200px"}插件的contextMenu选项：

$(function () {
    "use strict";
    var mydata = [
