jQuery发布方法调用ColdFusion组件功能不起作用

Question

我想通过使用jQuery的post（）方法调用通过ajax的cfc方法，但我不断收到一条错误消息，说“需要yyy函数的xxx参数但没有通过“。这是我的CFC功能：

<cffunction name="updateAssessment" returntype="struct" returnformat="json" access="remote" hint="For ajax update of a single assessment record"> 
    <cfargument name="data" type="JSON" required="true" hint="Data structure received from ajax call"> 

    <cfset var incomingData = "" /> 
    <cfset var qry = "" /> 
    <cfset var resultset = {success:false,message:"invalid data"}> 

    <cfif IsJSON(arguments.data)> 
     <cfset incomingData = deserializeJSON(arguments.data) /> 
    </cfif> 

    <cfreturn resultset /> 
</cffunction> 

，这里是jQuery代码调用它：

$('.ajaxSubmitBtn').on('click', function() { 

     //grab values from editable table cells... 
     var assessmentid = $.trim($(this).closest('tr').find('.ajaxSubmitBtn').val()); 
     var source = $.trim($(this).closest('tr').find('.sourceTD').text()); 
     var lname = $.trim($(this).closest('tr').find('.lnameTD').text()); 
     var fname = $.trim($(this).closest('tr').find('.fnameTD').text()); 
     var ssn = $.trim($(this).closest('tr').find('.ssnTD').text()); 
     var assessdate = $.trim($(this).closest('tr').find('.assessdateTD').text()); 
     var casehranum = $.trim($(this).closest('tr').find('.casehranumTD').text()); 
     var dob = $.trim($(this).closest('tr').find('.dobTD').text()); 

     //Put values in a JSON object... 
     var JSONPacket = { 
      "assessmentid":assessmentid, 
      "source":source, 
      "lname":lname, 
      "fname":fname, 
      "ssn":ssn, 
      "assessdate":assessdate, 
      "casehranum":casehranum, 
      "dob":dob 
      } 

     //call cfc function via ajax using post() 
     $.post("../../../cfc/starsImporter.cfc", {method: "updateAssessment", data: JSONPacket}, 
      function(response) { 
       console.log(response); 
      }, 
     "json"); 
    }); 

我清楚地传递所需的参数CFC功能与“数据：JSONPacket”，所以不知道是什么问题是。

我想你需要单独传递参数。它现在写入的方式，jQuery是经过data结构作为串的钥匙状data[source]

$('.ajaxSubmitBtn').on('click', function() { 

    //grab values from editable table cells... 
    var assessmentid = $.trim($(this).closest('tr').find('.ajaxSubmitBtn').val()); 
    var source = $.trim($(this).closest('tr').find('.sourceTD').text()); 
    var lname = $.trim($(this).closest('tr').find('.lnameTD').text()); 
    var fname = $.trim($(this).closest('tr').find('.fnameTD').text()); 
    var ssn = $.trim($(this).closest('tr').find('.ssnTD').text()); 
    var assessdate = $.trim($(this).closest('tr').find('.assessdateTD').text()); 
    var casehranum = $.trim($(this).closest('tr').find('.casehranumTD').text()); 
    var dob = $.trim($(this).closest('tr').find('.dobTD').text()); 

    //Put values in a JSON object... 
    var JSONPacket = { 
     "method" : "updateAssessment", 
     "assessmentid":assessmentid, 
     "source":source, 
     "lname":lname, 
     "fname":fname, 
     "ssn":ssn, 
     "assessdate":assessdate, 
     "casehranum":casehranum, 
     "dob":dob 
     } 

    //call cfc function via ajax using post() 
    $.post("../../../cfc/starsImporter.cfc", JSONPacket, 
     function(response) { 
      console.log(response); 
     }, 
    "json"); 
});

明白了 - 问题是，我需要在发布前字符串化的JSONPacket它到了cfc方法。并且，在创建JSON对象后放置一个分号。所以一切看起来像这样：

<cffunction name="updateAssessment" returntype="struct" returnformat="JSON" access="remote" output="false" hint="For ajax update of a single assessment record"> 
    <cfargument name="JSONPacket" type="string" required="true" hint="Data structure received from ajax call"> 

    <cfset var incomingData = "" /> 
    <cfset var qry = "" /> 
    <cfset var resultset = {success:false,message:"invalid data"}> 

    <cfif IsJSON(arguments.JSONPacket)> 
     <cfset incomingData = deserializeJSON(arguments.JSONPacket) /> 
    </cfif> 

    <cfreturn resultset /> 
</cffunction> 


$('.ajaxSubmitBtn').on('click', function() { 
     //console.log("Hello"); 
     var assessmentid = $.trim($(this).closest('tr').find('.ajaxSubmitBtn').val()); 
     var source = $.trim($(this).closest('tr').find('.sourceTD').text()); 
     var lname = $.trim($(this).closest('tr').find('.lnameTD').text()); 
     var fname = $.trim($(this).closest('tr').find('.fnameTD').text()); 
     var ssn = $.trim($(this).closest('tr').find('.ssnTD').text()); 
     var assessdate = $.trim($(this).closest('tr').find('.assessdateTD').text()); 
     var casehranum = $.trim($(this).closest('tr').find('.casehranumTD').text()); 
     var dob = $.trim($(this).closest('tr').find('.dobTD').text()); 
     var JSONPacket = { 
      "assessmentid":assessmentid, 
      "source":source, 
      "lname":lname, 
      "fname":fname, 
      "ssn":ssn, 
      "assessdate":assessdate, 
      "casehranum":casehranum, 
      "dob":dob 
      }; 

     $.post("../../../cfc/starsImporter.cfc", {method:"updateAssessment", JSONPacket:JSON.stringify(JSONPacket)}, 
      function(response) { 
       console.log(response); 
      }, 
     "JSON"); 
    });
