重新加载不适用于jqgrid [英] reload not working for jqgrid
本文介绍了重新加载不适用于jqgrid的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
以下代码不会重新加载网格.
The following code does not reload the grid.
$("#myjqgrid").trigger('reloadGrid');
如果我理解正确，即使没有数据更改，它也应该进行ajax调用并重新加载网格.
If I understand it correctly, it should make an ajax call and reload the grid even if there are no changes to the data.

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

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",
repeatitems: false
},
gridview: true,
pager: "#Pager",
rowNum: 21,
rowList: [21],
viewrecords: true,
recordpos: 'left',
multiboxonly: true,
multiselect: true,
sortname: 'ID',
sortorder: "desc",
sorttype: "text",
sortable: true,
caption: "<h2>MY JQGRID</h2>",
width: "1406",
height: "100%",
scrolloffset: 0,
loadonce: true,
cache: true,
loadComplete: function(data){
}
});
$("#myjqgrid").jqGrid('navGrid','#Pager', {add:false, edit:false, del:false, position: 'right'});
$("#myjqgrid").jqGrid('gridResize',{minWidth:800,maxWidth:1405,minHeight:350,maxHeight:680});
$("#myjqgrid").trigger('reloadGrid');
}
});
});
推荐答案
在我看来，您对loadonce: true只是有问题，它会在第一次加载数据后将datatype更改为本地".因此，数据的分页，排序和过滤在本地有效.
It seems to me that you have just problem with loadonce: true which change the datatype to 'local' after the first load of data. So the paging, sorting and filtering of data works locally.
如果您确切地了解什么是分页，排序和过滤，您会发现它的变化更多是因为更改了jqGrid的某些参数并在本地 重新加载了网格.因此，分页，排序和筛选仅在本地工作，因为网格的重新加载在本地工作.
If you look exactly what is paging, sorting and filtering you will see that it's mot more as changing of some parameters of jqGrid and reloading of the grid locally. So the paging, sorting and filtering work locally only because the reload of the grid works locally.
如果您需要从服务器刷新网格的数据，只需将datatype重置为其初始值('json'或'xml')，然后重新加载网格.
If you need to refresh the data of the grid from the server you need just reset the datatype to it's initial value ('json' or 'xml') and then reload the grid.
