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;
    }
}
