我有一个 jqGrid，它向我的服务器发送 ajax 请求。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与转换器一起使用。因此，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)。
有人可以帮我解决这个问题吗？
这是我的代码:

===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":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="dfbab2beb6b39fe7edebeaefebf1bcb0b2" rel="noreferrer noopener nofollow">[email protected]</a>",
"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":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2e5d4b4d41404a4f5c576b434f47426e161c1a1b1e1a004d4f" rel="noreferrer noopener nofollow">[email protected]</a>"}
},{
"userAccountId":44,
"clientAccount":{"clientAccountId":45,"name":"name:3136","firstName":"firstName:3136","lastName":"lastName:3136","active":true},
"userName":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="07626a666e6b47303e313436352964686a" rel="noreferrer noopener nofollow">[email protected]</a>",
"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":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="512234323e3f35302328143c30383d116668676260637f3230" rel="noreferrer noopener nofollow">[email protected]</a>"}
}]
,"pagination":{"pageSize":10,"pageNumber":2,"totalItems":49}}}
所以，我已经有一个函数可以将此响应解析为如下所示。我想将这个解析后的响应与 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" : "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="740711171b1a1015060d3119151d18344c46404144405a1715" rel="noreferrer noopener nofollow">[email protected]</a>"
},{
"id" : "3", "name" : "firstName796312", "email" : "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="84f7e1e7ebeae0e5f6fdc1e9e5ede8c4b3bdb2b7b5b6aae7e5" rel="noreferrer noopener nofollow">[email protected]</a>"
}]
};
===最终代码===
我成功了。谢谢您的帮助。这是我的功能示例。我希望它能在未来帮助其他人。
$(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,

},

});
最佳答案
您以错误的方式使用 jqGrid 选项。重要的是要理解 jqGrid 需要“知道”一些参数，例如 url 和 datatype。如果未指定datatype，则将使用默认值“xml”。
您不应覆盖 jqGrid 中已存在的 ajaxGridOptions 参数。所以你应该正确使用jqGrid。如果 URL "../rush-controller-testing/userAccount/find" 返回您在 parsedResponse 中包含的格式的数据，那么您的代码可能如下:
myGrid.jqGrid({
url: "../rush-controller-testing/userAccount/find",
datatype: "json",
mtype: "POST",
pager: "#useraccount-search-datagrid-pager",
serializeGridData : function(data) {
// the function is DUMMY. it MUST be replaced
return '{"SearchCriteria": {"keyword":"emai","orderByField":"userName","sortOrder":"DESC","pagination":{"pageSize":"10","pageNumber":"2"}}}';
},
ajaxGridOptions: { contentType: "application/json; charset=utf-8" },
colModel: [
{ name: 'id', key: true, width: 100 }
{ name: 'name', width: 400 }
],
jsonReader: {
root: "myData",
page: "currentPage",
records: "totalRecords",
repeatitems: false
},
rowNum: 3,
gridview: true,
autoencode: true,
viewrecords: true,
height: "auto",
ignoreCase: true,
hidegrid: false
});
确实需要在 jsonReader 内部使用 repeatitems: false 属性。我认为您不需要使用 jQuery.ajax 的任何转换器。
