场景：当记录被锁定（因为审批操作而锁定）后，非超级管理员不能通connection.js的如下方式更新字段：

{!REQUIRESCRIPT("/soap/ajax/40.0/connection.js")}alert('确认后，该项目将发布至项目比选平台！');var tp = new sforce.SObject('Tender_Project__c');tp.id = "{!Tender_Project__c.Id}";tp.isPublished__c = true;tp.Compare_Stage__c = '比选应标';var result = sforce.connection.update([tp]);if(result[0].getBoolean("success")) {    alert('发布成功！');    window.location.reload();}else {    alert('网络异常，请尝试重新发送，仍然出现请联系系统管理员！');}

{!REQUIRESCRIPT("/soap/ajax/19.0/connection.js")} //adds the proper code for inclusion of AJAX toolkitvar url = parent.location.href; //string for the URL of the current pagevar records = {!GETRECORDIDS($ObjectType.Lead)}; //grabs the Lead records that the user is requesting to updatevar updateRecords = []; //array for holding records that this code will ultimately updateif (records[0] == null) { //if the button was clicked but there was no record selectedalert("Please select at least one record to update."); //alert the user that they didn't make a selection } else { //otherwise, there was a record selectionfor (var a=0; a<records.length; a++) { //for all recordsvar update_Lead = new sforce.SObject("Lead"); //create a new sObject for storing updated record detailsupdate_Lead.Id = records[a]; //set the Id of the selected Lead recordupdate_Lead.Status = "Unqualified"; //set the value for Status to 'Unqualified'updateRecords.push(update_Lead); //add the updated record to our array}result = sforce.connection.update(updateRecords); //push the updated records back to Salesforceparent.location.href = url; //refresh the page}

现状：超级管理员的身份能点击按钮更新字段，没有那么高权限的专员点击按钮不能更新，并提示错误信息。

错误信息：{errors:{message:'此记录已锁定。如果您需要编辑，请联系您的管理员。', statusCode:'ENTITY_IS_LOCKED', }, id:null, success:'false', }

workaround：使用webservices，通过call apex来提高系统用户的权限。

步骤：
1、编写webservice类：

global class UpdateStateByCustomButtonFunction {    webservice static String updateState(ID recId){     String errMsg = '发布成功！';    Tender_Project__c tp = new Tender_Project__c();    tp.Id = recId;    tp.Is_Published__c = true;    try{    update tp;    }catch(DmlException e) {    System.debug('update error: '+e.getMessage());    errMsg = '网络异常，请尝试重新发送，仍然出现请联系系统管理员！';    }return errMsg;}}

2、添加该类到相关操作专员简档，允许专员访问该apex类；

3、编写js逻辑：

{!REQUIRESCRIPT("/soap/ajax/40.0/connection.js")} {!REQUIRESCRIPT("/soap/ajax/40.0/apex.js")} alert('确认后，该项目将发布至项目比选平台！'); var result = sforce.apex.execute("UpdateStateByCustomButtonFunction","updateState",{recId:"{!Tender_Project__c.Id}"});//类名，方法名，参数 if(result = '发布成功！') { alert(result); location.reload(); }else { alert('网络异常，请尝试重新发送，仍然出现请联系系统管理员！') }

=====================================================

问题2：在记录锁定的情况下，通过自定义button，输入并更新记录的某一字段？

solution：在alert中输入值，并利用ajax更新字段。
