JQGrid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
这是更改div#t_myjqgrid内容的正确方法吗?还是jqgrid提供了我可以使用的属性/方法/事件?
Is this the right way of changing the content of div#t_myjqgrid? Or does jqgrid offer a property/method/event that I can use?
推荐答案
jqGrid的toolbar选项没有更改内容顶部或底部工具栏的方法，但是您可以使用setCaption设置网格标题(标题).对代码进行小的修改的演示使用以下loadComplete :
There are no methods for changing of content top or bottom toolbars added by toolbar option of jqGrid, but you can use setCaption to set grid caption (title). The small modified demo of your code uses the following 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>');
}
}
如果网格的id(在您的情况下为"myjqgrid")包含某些
The usage of $.jgrid.jqID(this.id) instead of this.id is helpful in the case if the id of the grid (in you case 'myjqgrid') contains some meta-characters.
