Question

我有一个旧项目要处理（asp .net MVC）。 使用带有提交按钮的Ajax.BeginForm 时。它调用操作方法两次。可能是什么原因？

控制器来源：

let $query-name := "get-asset-sub-group-values"
let $output-dir :=  "D:\output\"
let $report-uri := concat($output-dir, $query-name, "_report2.txt")


let $enumValues := (:sequence of strings are passed:)

let $result1 :=( concat('asset-id' , "|",  'upi',  "|", 'assetSubGroup',  "|",  'asset-type',  "|", 'asset-sub-type', "|", 'originator', "|", 'originator-identifier',  "|",  'mm-project-id',  "|" , 'sap-project-id' , "&#10;"),

  for $each-search-copy in cts:search(collection("metadata-search"), cts:element-value-query(xs:QName("AssetID"), "*"))/metadata
    let $asset-id := $each-search-copy/assetIdentifiers/assetIdentifier/AssetID[1]/text()
    let $upi := $each-search-copy/assetIdentifiers/assetIdentifier/SAPID[1]/text()
    let $asset-type := $each-search-copy/biblioCore/assetType[1]/text()
    let $asset-sub-type := $each-search-copy/biblioCore/assetSubType[1]/text()
    let $originator := $each-search-copy/biblioCore/originator[1]/text()
    let $originator-identifier := $each-search-copy/assetIdentifiers/assetIdentifier/OriginatorIdentifier[1]/text()
    let $mm-project-id := $each-search-copy/biblioCore/MMProjectID[1]/text()
    let $sap-project-id := $each-search-copy/biblioCore/SAPProjectID[1]/text()
    let $assetSubGroup := $each-search-copy/biblioCore/assetSubGroup[1]/text()
    let $flag := ($assetSubGroup eq $enumValues)
    return
        if ($flag)
            then()
            else (
                  concat($asset-id , "|",  $upi,  "|", $assetSubGroup,  "|",  $asset-type,  "|", $asset-sub-type, "|", $originator, "|", $originator-identifier,  "|",  $mm-project-id,  "|" , $sap-project-id , "&#10;")
                 ))

return xdmp:save($report-uri, text{$result1}), xdmp:elapsed-time()

HTML：

PatientDataProvider.AddPatient(patient);
return Json(new { redirection = "goToIndex" }, JsonRequestBehavior.AllowGet);

这是按钮：

@using (Ajax.BeginForm("AjouterPatient", "Patient", new AjaxOptions { HttpMethod = "POST", OnSuccess = "OnSuccess" }))

OnSuccess 方法：

<button class="btn btn-sm btn-success" type="submit">
   <i class="ace-icon fa fa-check"></i>
       Save
</button>

谢谢。

ASP.NET AJAX.BeginForm发送两次请求并添加重复项
