使用动态列绑定显示jqgrid时出现问题
我试图从struts操作中传递colModel和columns。就像问题里说的一样 我不确定我错过了什么。请帮忙。花了相当长的时间试图把它弄对 jsp: 谢谢。在我的测试中成功了。尽管如此,因为您的问题对许多jqGrid用户来说很有趣,所以我想在您的代码和JSON数据中为您编写一些小错误和优化 第一个也是最重要的问题是项目的ID。使用动态列绑定显示jqgrid时出现问题,jqgrid,Jqgrid,我试图从struts操作中传递colModel和columns。就像问题里说的一样 我不确定我错过了什么。请帮忙。花了相当长的时间试图把它弄对 jsp: 谢谢。在我的测试中成功了。尽管如此,因为您的问题对许多jqGrid用户来说很有趣,所以我想在您的代码和JSON数据中为您编写一些小错误和优化 第一个也是最重要的问题是项目的ID。jsonReader内部的设置id:“0”错误。仅当数据项是数组而不是具有命名属性的对象(repeatitems:false)时,才可以使用它。当前作为行的ID将使用
jsonReader
内部的设置id:“0”
错误。仅当数据项是数组而不是具有命名属性的对象(repeatitems:false
)时,才可以使用它。当前作为行的ID将使用整数1,2,。。。我严格建议您在JSON数据的rootVar
项中包含id信息
下一个问题。属性“title”:“03-01-11”
错误。colModel
的属性是布尔值,因此应该将其更改为“title”:true
。关闭问题:将属性resizeable
用作resizeable
,这在英语中可能更正确,但jqGrid将忽略它
现在进行一些小优化:
datatype:'jsonstring',datastr:colD
更改为datatype:'local',data:colD.rootVar
gridview:true
参数数据类型:'jsonstring'
或数据类型:'local'
,则将忽略设置url:'SomeUrl/Getdata'
,以及mtype:'POST'
。所以您应该删除jqGrid的参数jsonmap
不会在您的数据模型中使用,所以我建议您将其从JSON数据中删除colModel
的附加标签
属性。在这种情况下,您将不再需要colNames
(columnNames
在数据中)type
更改为`type:“GET”,因为我没有活动的服务器组件,并将JSON保存为文本文件)。我建议的修改后的相同演示是
该方法的主要限制是所有数据都是本地的。因此,您可以使用本地排序、筛选和分页,但如果您确实希望使用服务器端排序、筛选和分页,则必须在jqGrid中包含更多的额外代码
我建议您使用的结果代码是:
$(document).ready(function () {
$.ajax({
type: "GET",
url: "DynamicColumnBinding1.txt",
dataType: "json",
success: function(result){
var colD = result.couponStripList,
colM = result.colModelList;
$("#dataGrid").jqGrid({
datatype: 'local',
data: colD.rootVar,
gridview: true,
colModel :colM,
height: "auto",
loadComplete: function(data){
alert('loaded');
},
loadError: function(xhr,status,error){
alert('error');
}
});
},
error: function(x, e){
alert(x.readyState + " "+ x.status +" "+ e.msg);
}
});
});
例如,对应的JSON数据如下
{
"colModelList": [
{
"index": "prceCM",
"label": "CM",
"name": "prceCM",
"width": 100
},
{
"index": "prceCMPlusOne",
"label": "CM + 1",
"name": "prceCMPlusOne",
"width": 100
},
{
"index": "prceCMPlusTwo",
"label": "CM + 2",
"name": "prceCMPlusTwo",
"width": 100
},
{
"index": "prceCMPlusThree",
"label": "CM + 3",
"name": "prceCMPlusThree",
"width": 100
},
{

谢谢你,奥列格。节省了我的时间。几天前开始使用jquery和jqgrid,现在仍在学习。至于这个问题,我的意思是使用lable而不是title,谢谢你的详细回答。@Oleg&@Silpa:我的jqgrid定义与你的相同。我的JSON有点不同。我很难使用
jsonmap
将单元格映射到每一列。请看一看-没有办法-它只是工作。完美地奥列格,你真是个天才!!为我节省了很多工作时间。呼:)@peterRunnings:我很高兴能帮助你。不客气!
