jqgrid - 工具栏文本 - 这是做这件事的好方法吗？

Question

我已经在JSON响应中指定了userdata。根据title属性的值，

• 标题将改变以反映title财产
• 工具栏中的文本（网格标题和数据表头之间）的值将改变

HTML

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

jqGrid的定义

$(document).ready(function() { 
    $.ajax({ 
     type: "GET", 
     url: "myjqgrid.json", 
     data: "", 
     dataType: "json", 
     success: function(response){ 
      var columnData = response.mypage.outerwrapper, 
       columnNames = response.colNames, 
       columnModel = response.colModel; 

      $("#myjqgrid").jqGrid({ 
       datatype: 'jsonstring', 
       datastr: columnData,     
       colNames: columnNames, 
       colModel: columnModel, 
       jsonReader: { 
        root: "innerwrapper.rows", 
        userdata: "innerwrapper.userdata",    
        repeatitems: false 
       }, 
       gridview: true, 
       pager: "#Pager", 
       rowNum: 21, 
       rowList: [21], 
       viewrecords: true,    
       recordpos: 'left', 
       multiboxonly: true, 
       multiselect: true, 
       width: "1406",  
       height: "auto", 
       loadonce: true, 
       toolbar: [true,"top"], 
       loadComplete: function(){ 
        var userdata = $("#myjqgrid").jqGrid('getGridParam', 'userData'); 
        if (userdata) { 
         if (userdata.title) { 
          $("#myjqgrid").jqGrid('setCaption', userdata.title); 
         } 
        } 
        if (userdata.title === "My Title 1") { 
         $("div#t_myjqgrid").append("Viewing the Records."); 
        } else if (userdata.title === "My Title 2") { 
         $("div#t_myjqgrid").append("Editing the Records."); 
        } 
       } 
      }); 
      $("#myjqgrid").jqGrid('navGrid','#Pager', {add:false, edit:false, del:false, position: 'right'}); 
     } 
    }); 
}); 

我的问题是

这是改变div#t_myjqgrid内容的正确方法吗？或者，jqgrid提供了一个我可以使用的属性/方法/事件？

没有方法更改jqGrid的toolbar选项添加的顶部或底部工具栏的内容，但可以使用setCaption来设置网格标题（标题）。小修改代码的demo使用以下loadComplete：

loadComplete: function() { 
    var $this = $(this), userdata = $this.jqGrid('getGridParam', 'userData'); 
    if (userdata && userdata.title) { 
     $this.jqGrid('setCaption', userdata.title); 
    } 
    if (userdata.title === "My Title 1") { 
     $this.jqGrid('setCaption', "Viewing the Records."); 
     $('#t_' + $.jgrid.jqID(this.id)) 
      .append('<div style="margin: 0.3em">Viewing the Records.</div>'); 
    } else if (userdata.title === "My Title 2") { 
     $this.jqGrid('setCaption', "Editing the Records."); 
     $('#t_' + $.jgrid.jqID(this.id)) 
      .append('<div style="margin: 0.3em">Editing the Records.</div>'); 
    } 
} 

的$.jgrid.jqID(this.id)代替this.id的用法是在如果电网的id（在你的情况下“myjqgrid”）的情况下有用包含一些meta-characters。
