005_重写 Standard Delete Button

{!REQUIRESCRIPT("/soap/ajax/32.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/32.0/apex.js")}

var record = new sforce.SObject("Opportunity");
record.Id = '{!Opportunity.Id}';

//copy opportunity line items
result = sforce.connection.query("Select PricebookEntry.Product2.Name, Quantity, TotalPrice From OpportunityLineItem WHERE OpportunityId = '{!Opportunity.Id}' and (NOT Name like '%Discount%')");
records = result.getArray("records");

var strProductNames = '';
for(var i=0; i<records.length ; i++){
 strProductNames += 'PRODUCT NAME: ' + records[i].PricebookEntry.Product2.Name + ' --- QUANTITY: ' + records[i].Quantity + ' --- TOTAL PRICE: $ ' + records[i].TotalPrice +',
';
}

if(strProductNames.length>0){
 strProductNames = strProductNames.substring(0,strProductNames.length-2);
}
record.Samples_Sent__c = strProductNames;

//delete opportunity line items
var lineItems = sforce.connection.query("select id from opportunitylineitem where opportunityid = '{!Opportunity.Id}'")
var oliIds = []
var qri = new sforce.QueryResultIterator(lineItems)
while(qri.hasNext())
    oliIds.push(qri.next().Id)
sforce.connection.deleteIds(oliIds)

sforce.connection.update([record]);
window.location.reload();

　　

-------------------------------------------------------------------以下的方法是以传统的，适用于较多的业务逻辑的方式。页面->Controller

以后会用JS直接删除，但是在加载.js时候出现问题，会在以后进一步追踪完善：

<apex:page standardController="Opportunity" >
<!--extensions="accountDelete" action="{!deleterecord}"-->

<script type="text/javascript">
var __sfdcSessionId = '{!GETSESSIONID()}';
</script>

<script src="../../soap/ajax/35.0/connection.js" type="text/javascript"></script>

<script type="text/javascript">

window.onload = setupPage;

function setupPage() {
if('{!Opportunity.Name}'=='ddd33'){
alert('{!Opportunity.Name}');
window.top.location = '/' + '{!Opportunity.Id}';
} else{
sforce.connection.deleteIds('{!Opportunity.Id}');
alert('123456');
window.top.location = '/' + '001/o'; }
}

</script>

</apex:page>

——————————————————————————————————————————————————————————

<apex:page standardController="Account" extensions="accountDelete" action="{!deleterecord}">
    <apex:pageMessages />
</apex:page>

public with sharing class accountDelete {

    apexpages.standardcontroller controller;
    public accountDelete(ApexPages.StandardController controller) {
        this.controller = controller;
    }
    public pagereference deleteRecord() {
        try {
            delete controller.getRecord();
            return new pagereference('/home/home.jsp');  //return new pagereference('/001/o');   ----------执行完controller 后跳转到的页面；
        } catch(exception e) {
            apexpages.addmessages(e);
        }
        return null;
    }
}
