Ajax请求从服务中获取其他记录 [英] Ajax request fetch additional records from the service

问题描述

Hi,

I have defined data parameters of AJAX request as follows

    "{"take":200,"reportId":"D:\\Sample\\Listbox sample\\DashboardServiceInstaller\\DashboardServiceInstaller\\DashboardServiceInstaller\\listbox sample.sydx","controlId":"ListBox_1","masterData":"[{\"Key\":\"ListBox_1\",\"Value\":[{\"Items\":[]}],\"MultiSelection\":false,\"Filter\":\"Exclude\"}]","rangeData":"[]","modifiedConnectionStrings":"\"\"","listboxRowCount":"1096","currentUser":"null","isPublic":false,"skip":800}"

and ajax request is defined as follows

    $.ajax({
         beforeSend : ()
         cache : true
         contentType : "application/json; charset=utf-8"
         crossDomain : undefined
         data: "{"take":200,"reportId":"D:\\Sample\\Listbox sample\\DashboardServiceInstaller\\DashboardServiceInstaller\\DashboardServiceInstaller\\listbox sample.sydx","controlId":"ListBox_1","masterData":"[{\"Key\":\"ListBox_1\",\"Value\":[{\"Items\":[]}],\"MultiSelection\":false,\"Filter\":\"Exclude\"}]","rangeData":"[]","modifiedConnectionStrings":"\"\"","listboxRowCount":"1096","currentUser":"null","isPublic":false,"skip":800}"
        dataType : "json"
        ejPvtData : Object
        error : ()
        jsonp : "callback"
        processData : false
        success : ()
        type : "POST"
        url : "http://localhost:3002/DashboardService.svc/GetListBoxRows"
})

Once ajax request raise to the service, the request url and Request Payload as follows

> Request URL:http://localhost:3002/DashboardService.svc/GetListBoxRows

and Request Payload
> 1.	controlID : "ListBox_1"
> 2.	currentUser:"null"
> 3.	isPublic:false
> 4.	listboxRowCount:"1096"
> 5.	masterData:"[{"Key":"ListBox_1","Value":[{"Items":[]}],"MultiSelection":false,"Filter":"Exclude"}]"
> 6.	modifiedConnectionStrings:""""
> 7.	rangeData:"[]"
> 8.	reportId:"D:\Sample\Listbox sample\DashboardServiceInstaller\DashboardServiceInstaller\DashboardServiceInstaller\listbox
> sample.sydx"
> 9.	skip:600
> 10.	take:200

我尝试过：

What I have tried:

My requirement : I need to fetch the 200 records only from the service but it has fetching 201 records, even though i defined take 200.

> data.d Array[201] [0 … 99] [100 … 199] 200 : Object

Length is 201

Why i am getting additional data, is there any way to fix this issue.

推荐答案

.ajax（{
beforeSend :(）
cache：true
contentType：application / json; charset = utf-8
crossDomain：undefined
data：{take：200，reportId：D：\\Sample \ \Listbox sample \\DashboardServiceInstaller \\DashboardServiceInstaller \\DashboardServiceInstaller\\listbox sample.sydx，controlId：ListBox_1，masterData：[{\Key \ ：\ ListBox_1\，\ Value\：[{\ Items\：[]}]，\ MultiSelection\：假，\ Filter\ ：\ Exclude\}]， rangeData： []， modifiedConnectionStrings： \ \ ， listboxRowCount： 1096， 当前用户： 空， isPublic：false，skip：800}
dataType：json
ejPvtData：对象
错误:(）
jsonp：回调
processData：false
成功:(）
类型：POST
url：http：// localhost：3002 / DashboardService.svc / GetListBoxRows
}）

一旦ajax请求加入服务，请求url和Request Payload如下

>请求URL：http：// localhost：3002 / DashboardService.svc / GetListBoxRows

和Request Payload
> 1. controlID：ListBox_1
> 2. currentUser：null
> 3. isPublic：false
> 4. listboxRowCount：1096
> 5. masterData：[{Key：ListBox_1，Value：[{Items：[]}]，MultiSelection：false，Filter：Exclude}]
> 6. modifiedConnectionStrings：
> 7. rangeData：[]
> 8. reportId：D：\ Sample \Listbox sample \ DashboardServiceInstaller \DashboardServiceInstaller \ DashboardServiceInstaller \ listbox
> sample.sydx
> 9.跳过：600
> 10.拿：200

.ajax({ beforeSend : () cache : true contentType : "application/json; charset=utf-8" crossDomain : undefined data: "{"take":200,"reportId":"D:\\Sample\\Listbox sample\\DashboardServiceInstaller\\DashboardServiceInstaller\\DashboardServiceInstaller\\listbox sample.sydx","controlId":"ListBox_1","masterData":"[{\"Key\":\"ListBox_1\",\"Value\":[{\"Items\":[]}],\"MultiSelection\":false,\"Filter\":\"Exclude\"}]","rangeData":"[]","modifiedConnectionStrings":"\"\"","listboxRowCount":"1096","currentUser":"null","isPublic":false,"skip":800}" dataType : "json" ejPvtData : Object error : () jsonp : "callback" processData : false success : () type : "POST" url : "http://localhost:3002/DashboardService.svc/GetListBoxRows" }) Once ajax request raise to the service, the request url and Request Payload as follows > Request URL:http://localhost:3002/DashboardService.svc/GetListBoxRows and Request Payload > 1. controlID : "ListBox_1" > 2. currentUser:"null" > 3. isPublic:false > 4. listboxRowCount:"1096" > 5. masterData:"[{"Key":"ListBox_1","Value":[{"Items":[]}],"MultiSelection":false,"Filter":"Exclude"}]" > 6. modifiedConnectionStrings:"""" > 7. rangeData:"[]" > 8. reportId:"D:\Sample\Listbox sample\DashboardServiceInstaller\DashboardServiceInstaller\DashboardServiceInstaller\listbox > sample.sydx" > 9. skip:600 > 10. take:200

Ajax 调用与无关取参数，它只是一个参数，你在服务方法中使用它来选择数据。

你会必须挖掘 GetListBoxRows 方法，以找到额外行在集合中的累加位置。

Ajax call has nothing to do with the take parameter, its just an argument which you are using in the service method to pick the data.
you will have to dig the GetListBoxRows method to find where the extra row is adding up in the collection.
