几天来,我一直在研究和尝试各种代码,但一直无法找到可靠的解决方案,所以我来找你们所有人,希望你们能指出我做错了什么。
在我的自定义VF页面上,我使用了4个HTML输入标记,当用户单击generate按钮时,我希望将输入值传递到Apex控制器中进行操作。
这是我现在所拥有的,减去这个问题不需要的代码。使用它,控制台输出始终为null...
页面代码:
<apex:page id="scheduler-page" standardController="Opportunity" extensions="DEMO_ScheduleOpportunityController" showHeader="false" sidebar="false" standardStylesheets="false">
<head>
<script type="text/javascript">
function Generate() {
// setting variables with data from the page
var codRequested = $("#datepicker").datepicker("getDate");
var velocityRequested = $("#velocity-input").val();
var mwdcRequested = $("#mwdc-input").val();
var seriesRequested = $("#seriesList").val();
// these 4 values displays properly in the JS console
console.log('codRequested: ' + codRequested);
console.log('velocityRequested: ' + velocityRequested);
console.log('mwdcRequested: ' + mwdcRequested);
console.log('seriesRequested: ' + seriesRequested);
// passing values to the actionscript
SetInitialVariables(codRequested, velocityRequested, mwdcRequested, seriesRequested);
}
</script>
</head>
<body>
<apex:form id="scheduler-form">
<apex:actionFunction name="SetInitialVariables" action="{!GenerateSchedule}">
<apex:param name="codRequested" value="" />
<apex:param name="velocityRequested" value="" />
<apex:param name="mwdcRequested" value="" />
<apex:param name="seriesRequested" value="" />
</apex:actionFunction>
<c:DEMOscheduleGeneration opportunity="{!opportunity}" seriesMap="{!seriesMap}" />
</apex:form>
<apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js" />
<apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js" />
</body>
组件代码:
<apex:component>
<div id="generateContainer" class="container">
<!-- generate button -->
<div id="generate-button-wrap">
<a id="generate" onclick="Generate()">Generate</a>
<!-- calls JQ Generate function -->
</div>
</div>
</apex:component>控制器代码:
public PageReference GenerateSchedule() {
String series = Apexpages.currentPage().getParameters().get('seriesRequested');
String mwdc = Apexpages.currentPage().getParameters().get('mwdcRequested');
String velocity = Apexpages.currentPage().getParameters().get('velocityRequested');
String cod = Apexpages.currentPage().getParameters().get('codRequested');
System.debug('Series: ' + series);
System.debug('MWdc: ' + mwdc);
System.debug('Velocity: ' + velocity);
System.debug('COD: ' + cod);
return null;

我认为你的解决方法很简单:你正在使用jQuery,而$与内部的Salesforce函数冲突。您需要使用noConflict。执行以下操作:
var j$ = jQuery.noConflict();
// setting variables with data from the page
var codRequested = j$("#datepicker").datepicker("getDate");
var velocityRequested = j$("#velocity-input").val();
....无论您在哪里使用$,都要使用j$。这应该可以解决您的问题。
