我有一个要求,我需要根据Object,从组件传递的字段以及在vf页面中显示的方式在闪电中显示动态表。
我尝试了以下代码:
应用
<aura:application access="GLOBAL" extends="ltng:outApp" >
<c:PMD_LightningHomepage object="Opportunity" fields="Id" limit="5" tableId="table1"/>
<aura:dependency resource="c:PMD_LightningHomepage " />
</aura:application>
组件
<aura:component controller="controller" implements="force:appHostable,flexipage:availableForAllPageTypes">
<ltng:require styles="/resource/SDLC212/assets/styles/salesforce-lightning-design-system-vf.min.css" />
<aura:attribute name="object" type="String" />
<aura:attribute name="limit" type="String" default="5" />
<aura:attribute type="sObject[]" name="latestRecords" />
<aura:attribute name="fields" type="String[]" default="Id,Name" />
<aura:attribute name="tableId" type="String"/>
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
<html xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<head>
</head>
<body>
<div class="wrapperscoop">
<div class="slds-card__header slds-grid">
<div class="slds-media slds-mcate">
<div class="slds-media__figure">
</div>
<div class="slds-media__body">
<h2 class="slds-text-heading--small slds-truncate">Recently Viewed</h2>
</div>
</div>
</div>
<div class="slds-card__body">
<section class="slds-card__body">
<div class="slds-scrollable--x">
<table class="slds-table slds-table--bordered slds-max-medium-table--stacked-horizontal">
<thead>
<tr class="slds-no-hover">
<aura:iteration items="{!v.fields}" var="field" >
<th class="slds-text-heading--label slds-size--1-of-6" scope="col">{!field}</th>
</aura:iteration>
</tr>
</thead>
<tbody id="{!v.tableId}">
</tbody>
</table>
</div>
</section>
</div>
</div>
</body>
</html>
</aura:component>
JS-控制器
({
doInit : function(component, event, helper) {
var action = component.get("c.getRecords");
var fields = component.get("v.fields");
var tableId = component.get("v.tableId");
action.setParams({
ObjectName : component.get("v.object"),
limits : component.get("v.limit"),
//alert('Check1' + fields);
fieldstoget : fields.join()
});
action.setCallback(this,function(response){
var delayMillis = 1000;
var state = response.getState();
if(state === 'SUCCESS'){
component.set("v.latestRecords",response.getReturnValue());
var retRecords = response.getReturnValue();
retRecords.forEach(function(s) {
var tableRow = document.createElement('tr');
fields.forEach(function(field){
var tableData = document.createElement('td');
var tableDataNode = document.createTextNode(s[field]);
tableData.appendChild(tableDataNode);
tableRow.appendChild(tableData);
});
// alert(tableId);
//alert('tableval' + document.getElementById(tableId) );
setTimeout(function() {
alert(document.getElementById(component.get(" {!v.tableId}")));
document.getElementById(component.get("{!v.tableId}")).appendChild(tableRow);
}, delayMillis);
});
}else if (state === "ERROR") {
console.log('Error');
}
});
$A.enqueueAction(action);
}
})
但是当我尝试从Vf页面调用它时,它无法获取div id并将其读取为null并因此显示以下错误:
错误:
此页面有错误。您可能只需要刷新它。错误 $ A.getCallback()[无法读取null的属性'appendChild']回调 失败:apex:// PMD_DispRecordsController / ACTION $ getRecords失败 descriptor:{markup:// c:PMD_LightningHomepage}
我做错了什么?
注意:当我不从Vf页面调用它时,此组件正常工作,即直接预览。
