【问题描述】：
我有一个 jqGrid，它将 ajax 请求发送到我的服务器。但是，我的服务器以完全不同的格式发送 json 响应（我无法更改它）。因此我需要解析来自服务器的响应，以便我的 jqGrid 可以正确显示数据。
如果我理解正确，我可以将 ajaxGridOptions 与 converters 一起使用。所以，我可以捕获响应并解析它。在我看来，转换器工作正常并正确解析响应。但是，jqGrid 不理解我解析的响应。它永远显示一条消息“正在加载...”（我可以在 firebug 中看到请求/响应很好，并且控制台中没有 javascript 错误）。
谁能帮我解决这个问题？
这是我的代码：

var myGrid = $('<table>').attr( "id", "useraccount-search-datagrid");
var myPager = $("<div>").attr("id", "useraccount-search-datagrid-pager");
$("body").append(myGrid, myPager);
myGrid.jqGrid({
pager : myPager,
// datastr: parsedResponse, // If I use these parameters and remove ajaxGridOptions then it will work fine with the local data
// datatype : "jsonstring", // If I use these parameters and remove ajaxGridOptions then it will work fine with the local data
serializeGridData : function(data) {

},

dataType: "json",
converters: { "text json": function (responseText) {
// console.log(responseText); // Shows the response string from the cerver
return parsedResponse;
}
},
success: function(data, textStatus, jqXHR ) {
// Nice! It shows 'parsedResponse' from 'converters'. Looks good so far.
console.log(data); console.log(textStatus); console.log(jqXHR);
}
},

});
</script>
</body>
</html>
=== 更新 ===
我的服务器响应类似于：
{"UserAccountSearchResult":{
"userAccounts":[{
"userAccountId":18,
"clientAccount":{"clientAccountId":19,"name":"name:5791","firstName":"firstName:5791","lastName":"lastName:5791","active":true},
"userName":"email@824504.com",
"password":"password824504",
"firstName":"firstName824504",
"lastName":"lastName824504",
"isActive":true,
"phoneNumbers":{"phoneNumberId":36,"number":824504824504},
"addresses":{"addressId":126,"country":"CANADA","provinceOrState":"ONTARIO","address":"address824504","city":"Windsor","postalCode":"postalCode824504"},
"emails":{"emailId":36,"email":"secondaryEmail@824504.ca"}
},{
"userAccountId":44,
"clientAccount":{"clientAccountId":45,"name":"name:3136","firstName":"firstName:3136","lastName":"lastName:3136","active":true},
"userName":"email@796312.com",
"password":"password796312",
"firstName":"firstName796312",
"lastName":"lastName796312",
"isActive":true,
"phoneNumbers":{"phoneNumberId":88,"number":796312796312},
"addresses":{"addressId":298,"country":"CANADA","provinceOrState":"ONTARIO","address":"address796312","city":"Greater Sudbury","postalCode":"postalCode796312"},
"emails":{"emailId":88,"email":"secondaryEmail@796312.ca"}
}]
,"pagination":{"pageSize":10,"pageNumber":2,"totalItems":49}}}
所以，我已经有了一个函数来解析这个响应，如下所示。我想将此解析后的响应与 jqGrid 一起使用，因为在我的应用程序中有很多这样的情况：
{"currentPage" : "1", "totalRecords" : 2, "pageSize" : 3,
"myData" :[{
"id" : "1", "name" : "firstName824504", "email" : "secondaryEmail@824504.ca"
},{
"id" : "3", "name" : "firstName796312", "email" : "secondaryEmail@796312.ca"
}]
};
=== 最终代码 ===
我让它工作了。谢谢您的帮助。这是我的功能示例。我希望它可以在未来对其他人有所帮助。
$(document).ready(function() {
/*
* Here I will have a very complex logic to parse the response from the server in something jqGrid can understand.
* Right now it is just a hard-coded string to make thinks easer to understand
*/
function parseResponse(responseText){
var parsedResponse = '{"currentPage" : "1", "totalRecords" : 5, "pageSize" : 3, "pageTotal" : 2,'
+ '"myData" :[{"id" : "1", "name" : "Name 1" },'
+ ' { "id" : "3", "name" : "Name 3" },'
+ ' { "id" : "2", "name" : "Name 2" }]'
+ '}';
return JSON.parse(parsedResponse);
};
var myGrid = $('<table>').attr( "id", "useraccount-search-datagrid");
var myPager = $("<div>").attr("id", "useraccount-search-datagrid-pager");
$("body").append(myGrid, myPager);
myGrid.jqGrid({
pager : myPager,
// datastr: parsedResponse, // If I use these parameters and remove ajaxGridOptions then it will work fine with the local data
datatype : "json",
url: "../rush-controller-testing/userAccount/find",
mtype: "POST",
serializeGridData : function(data) {
// That is just a hard-coded example to make things easier to understand. Will change it to a more complex logic later.
return '{"SearchCriteria": {"keyword":"emai","orderByField":"userName","sortOrder":"DESC","pagination":{"pageSize":"10","pageNumber":"3"}}}';
},
ajaxGridOptions: {
contentType: "application/json; charset=utf-8",
},
colModel : [
{ name : 'name', index : 'name', width : "500"}
],
jsonReader: {
repeatitems: false,
root: function(data){
//the actual data
var result = parseResponse(data);
return result.myData;
},
total: function(data) {
//total pages for the query
var result = parseResponse(data);
return result.pageTotal;
},
page: function(data){
//current page of the query
var result = parseResponse(data);
return result.currentPage;
},
records: function(data){
//total number of records for the query
var result = parseResponse(data);
return result.totalRecords;
}
},
rowNum : 3,
viewrecords : true,
height : "auto",
ignoreCase : true,
hidegrid: false
});
});
【问题讨论】：
-
服务器发回的这种“奇怪的格式”是什么？
-
这不是错误，只是从服务器发回的响应（JSON 格式），我必须解析。
