Salesforce 使用Js 调用Webservice实例

1，创建 Custom Button 在页面上

2， 创建CustomJs 代码调用Webservice

 <!--参数名区分大小写，对于跨层object直接在Object名后直接加参字段名即可--> 
 {!REQUIRESCRIPT("/soap/ajax/30.0/connection.js")}
 {!REQUIRESCRIPT("/soap/ajax/30.0/apex.js")} 

 var OppID='{!Opportunity.Id}'
 var OppName = '{!Opportunity.OwnerLastName},{!Opportunity.OwnerFirstName}'
 var hello = sforce.apex.execute("WSReturn", "Hello", {id:OppID,username:OppName});
 alert(hello);

3，编写Webservice代码

 global class WSReturn {
     webservice static string Hello(string id,string username){
         string sayHello;

         sayHello = 'Hi '+username+', your id is:'+id;
         system.debug('say hello');

         return sayHello;
     }
 }
