使用 ajax 提交表单。将url变量传递给cfc中的coldfusion函数

Question

我正在为仪表板页面制作一个过滤器，其中包含从 ajax 调用提供给我的数据库的一堆图表，并从中制作一个 json 结构。我对过滤器有点迷茫，因为基本上每个字段都是可选的。现在我正在使用 jquery 和 formvalidator.io 提交 from。它将 from 值发送到最初绘制我的图表的函数。我迷路的地方是在我的coldfusion处理程序中，它将数据传递给coldfusion函数。如何传递动态数量的参数？

代码：

使用 jquery 提交表单：

$('#overviewFilter').formValidation({
            framework: 'bootstrap4'
        }).on("success.form.fv", function(e) {
            // Prevent form submission
            e.preventDefault();
            projectOverview();
        });

projectOverview 函数的Json 部分。我在那里有 serializeArray() 位，但我只是在试验，这可能有点离谱。

function projectOverview() {
    var formString = $('#overview_filter').serializeArray();
    $.getJSON('/a_assets/ajax/a_cms.cfm',{cms_action:'task_complete_history',form_data:formString}, function (data) {
    //charts 
    });

Coldfusion Handeler 代码。我在函数中有#url# 参数，因为我正在试验。

<cfif structKeyExists(url,"cms_action") and url.cms_action eq 'task_complete_history'>
    <cfobject name="cms" component="a_assets.cfc.cms">
    <cfset TaskHistoryNewComplete = cms.fnTaskHistoryNewComplete(#url#)>
    <cfoutput>#TaskHistoryNewComplete#</cfoutput>
</cfif>

Coldfusion CFC。我现在只有一个 formData 参数。对函数的每次调用都是一个查询，需要我要查找的值来过滤图表。

<cffunction name="fnTaskHistoryNewComplete" returntype="any" output="false">
        <cfargument name="formData" required="false">
        <cfset mydata = []>
        <cfset mydatatemp = structNew()>
        <cfset progressObj = []>
        <cfset TaskIntake = fnTaskIntake()>
        <cfloop query="TaskIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['Month'] = Month>
            <cfset mydatatemp2['Completed'] = Completed>
            <cfset mydatatemp2['Opened'] = Opened>
            <cfset mydatatemp2['Late'] = Late>
            <cfset arrayAppend(progressObj, mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['progress'] = progressObj>
        <cfset userObj = []>
        <cfset TaskUserIntake = fnTaskUserIntake()>
        <cfloop query="TaskUserIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['UserId'] = UserRcId>
            <cfset mydatatemp2['Fname'] = Fname>
            <cfset mydatatemp2['Lname'] = Lname>
            <cfset mydatatemp2['Assigned'] = TaskCount>
            <cfset arrayAppend(userObj,mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['users'] = userObj>
        <cfset typeObj = []>
        <cfset TaskTypeIntake = fnTaskTypeIntake()>
        <cfloop query="TaskTypeIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['TypeId'] = NFTypeRcId>
            <cfset mydatatemp2['Name'] = NFTDescription>
            <cfset mydatatemp2['TypeCount'] = TaskCount>
            <cfset arrayAppend(typeObj,mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['types'] = typeObj>
        <cfset tagObj = []>
        <cfset TaskTagIntake = fnTaskTagIntake()>
        <cfloop query="TaskTagIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['TagId'] = TagRcId>
            <cfset mydatatemp2['Name'] = Name>
            <cfset mydatatemp2['TagCount'] = TaskCount>
            <cfset arrayAppend(tagObj,mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['tags'] = tagObj>
        <cfset gameObj = []>
        <cfset TaskGameIntake = fnTaskGameIntake()>
        <cfloop query="TaskGameIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['GameId'] = GameRcId>
            <cfset mydatatemp2['Name'] = GameName>
            <cfset mydatatemp2['GameCount'] = TaskCount>
            <cfset arrayAppend(gameObj,mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['games'] = gameObj>
        <cfset platformObj = []>
        <cfset TaskPlatformIntake = fnTaskPlatformIntake()>
        <cfloop query="TaskPlatformIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['PlatformId'] = PlatformRcId>
            <cfset mydatatemp2['Name'] = Name>
            <cfset mydatatemp2['PlatformCount'] = TaskCount>
            <cfset arrayAppend(platformObj,mydatatemp2)>
        </cfloop>
        <cfset mydatatemp['platforms'] = platformObj>
        <cfset genreObj = []>
        <cfset TaskGenreIntake = fnTaskGenreIntake()>
        <cfloop query="TaskGenreIntake">
            <cfset mydatatemp2 = structNew()>
            <cfset mydatatemp2['GenreId'] = GenreRcId>
            <cfset mydatatemp2['Name'] = Name>
            <cfset mydatatemp2['GenreCount'] = TaskCount>
            <cfset arrayAppend(genreObj,mydatatemp2)>

        <cfset data['data'] = mydata>
        <cfset TaskHistoryNewComplete = serializeJson(mydata)>
        <cfreturn TaskHistoryNewComplete>
    </cffunction>

我确信我以前做过，但我一生都记不起我是怎么做到的。

单独关注每个问题。你说，The place I am getting lost at is in my coldfusion handeler that passes the data to a coldfusion function.这就是手头的问题。当你隔离它时，你会意识到你必须做这种事情。

<cfargument name = "optionalArgument" default = "defaultValue">
<cfif arguments.optionalArgument is "defaultValue">
code for that argument not provided
<cfelse>
code for argument is provided
</cfif>
