我似乎无法让 jqGrid 分页工作。当我单击next/prev/reload或尝试过滤时，它没有发出请求。只要我点击这些按钮中的任何一个，所有的记录都会消失。
这是发送的初始请求，因此您可以看到所有这些参数都被传入。
https://www.xxxxxxx.com/getallorders?contactId=333&bucketId=444&_search=false&nd=1366982305621&rows=20&page=1&sidx=PKId&sord=desc
这将返回正确数量的记录，如果我手动执行它并传入让我们说page=2我确实得到了正确的设置。问题似乎是没有提出请求。
jQuery("#grid").jqGrid({
url:'/GetAllOrders',
mtype: "GET",
datatype: "json",
jsonReader: {
root: "Rows",
page: "Page",
total: "Total",
records: "Records",
repeatitems: false,
userdata: "UserData",
id: "Id"
},
postData: {
contactId: currentUserId,
bucketId: currentBucketId
},
colNames:[
'Id',
'Cancel',
'Order #',
'Order Date',
'Bucket',
'Warehouse',
'Destination',
'Status',
'Tracking #',
'Transport By',
'Ordered By',
'Order Items'
],
colModel:[
{name:'Id',index:'Id', width:5, align:"center", hidden: true},
{name:'Cancel', index:'Cancel',width:80, align:"center", formatter: cancelLinkFormatter, search:false },
{name:'OrderNumber',index:'OrderNumber', width:80, align:"center"},
{name:'OrderDate',index:'OrderDate', width:140, align:'right'},
{name:'Bucket',index:'Bucket', width:180, align:"center", hidden: false},
{name:'Warehouse',index:'Warehouse', width:80, align:"center", hidden: true},
{name:'Destination',index:'Destination', width:150},
{name:'StatusCode', index:'StatusCode', width:100, align: 'center'},
{name:'TrackingNumber', index:'TrackingNumber', width:100, align: 'center'},
{name:'TransportCompany', index:'TransportCompany', width:100, align: 'center'},
{name:'OrderedBy', index:'OrderedBy', width:100, align: 'center'},
{name:'OrderItems', index:'OrderItems', width:100, align: 'center'}
],
viewrecords: true,
rowNum: 20,
autowidth: false,
width: 860,
height: 450,
rowList:[10,20,30,40,50],
pager: jQuery('#pager'),
sortname: 'Id',
align: 'center',
sortorder: "desc",
loadonce: false,
ignoreCase: true,
caption:"Orders"
}).navGrid('#pager',{edit:false,add:false,del:false});
setSearchSelect('StatusCode');
jQuery("#grid").jqGrid('filterToolbar', {stringResult: true, searchOnEnter: false, defaultSearch: "cn"});
这是我在初始加载时从服务器获得的 json 响应。
{
"Total":2,
"Page":1,
"Records":28,
"Rows":[
{
"PKId":1234,
"OrderNumber":"XXXXXX97",
"Cancel":"Cancel",
"OrderDate":"Jul 11 2012 12:37PM",
"Warehouse":"",
"Bucket":"xxxxxxxx",
"StatusCode":"Shipped Complete",
"StatusLink":"View Info",
"TrackingNumber":"xxxxxxx",
"TransportCompany":"xxxxxxxx",
"Destination":"xxxxxxx",
"BucketId":110,
"ShippingEmail":"xxxxxxxx",
"OrderedBy":"xxxxxxxx",
"OrderItem":"xxxxxxx"
},
.... MORE DATA HERE ... 20 OBJECTS ALL-TOGETHER WITHIN Rows Array
{
"PKId":13434,
"OrderNumber":"XXXXXX97",
"Cancel":"Cancel",
"OrderDate":"Jul 11 2012 12:37PM",
"Warehouse":"",
"Bucket":"xxxxxxxx",
"StatusCode":"Shipped Complete",
"StatusLink":"View Info",
"TrackingNumber":"xxxxxxx",
"TransportCompany":"xxxxxxxx",
"Destination":"xxxxxxx",
"BucketId":110,
"ShippingEmail":"xxxxxxxx",
"OrderedBy":"xxxxxxxx",
"OrderItem":"xxxxxxx"
},
],
"UserData":null
}
有什么建议么？
顺便说一句，当我使用和一次加载所有数据时，分页和过滤工作得很好loadonce: true，但是，由于记录太多，我只需要切换到服务器端。

我发现了问题。首先，很抱歉没有包括其余的代码。你看，我也有loadComplete，这对我来说是个问题。问题中的代码将起作用，所以我要感谢大家的参与。
这就是loadComplete导致问题的原因。一旦我删除它，它就开始正确分页。
loadComplete: function() {
setParamsOnComplete();
var myGrid = jQuery("#grid");
var ids = myGrid.getDataIDs();
for (var i = 0, idCount = ids.length; i < idCount; i++) {
jQuery("#"+ids[i]+" a",myGrid[0]).click(function(e) {
var hash=e.currentTarget.hash;// string like "#?id=0"
if (hash.substring(0,6) === "#S?id=") {
var id = hash.substring(6,hash.length);
var text = this.textContent || this.innerText;
dialog.dialog({ title: 'Status Information',
buttons:{ Ok: function() {
jQuery( this ).dialog("close");
}
},
open: function() {
jQuery('.ui-dialog-buttonpane').find('button:contains("Ok")').css('font-size', '10px');
}
});
dialog.dialog('open');
}
if (hash.substring(0,6) === "#C?id=") {
var id = hash.substring(6,hash.length);
var text = this.textContent || this.innerText;
var changed = false;
var additionalMesages = "";
jQuery.post("DataFetcher.asp", { 'action': "cancelOrder", 'id':id }, function(xml) {
changed = (xml === 'True');
additionalMesages = xml;
}).success(function(){
if (changed){
showDialogCustomTitle("Success", "You've successfully cancelled the order " + id + ".");
jQuery("#grid").setGridParam({datatype:'xml', page:1}).trigger('reloadGrid');
}else if (additionalMesages.split("_")[1] == "2"){
showDialogCustomTitle("Error", additionalMesages.split("_")[2]);
}else if (additionalMesages.split("_")[1] == "1"){
showDialogCustomTitle("Error", additionalMesages.split("_")[2]);
}
});
}
//e.preventDefault();
});
}
},
我的下一个任务可能是找出loadComplete导致问题的原因。

发现第一个问题loadComplete。昨晚我太累了，没有注意到它，但是这个网格填充 xml 并在客户端分页期间的剩余代码肯定会导致问题。再次感谢大家的参与。:)
jQuery("#grid").setGridParam({datatype:'xml', page:1}).trigger('reloadGrid');
