Salesforce 在标准sales force chatter页面中单击Approve/Reject链接时，是否可以显示自定义VF页面？

请告知我是否可以在单击记录上的“批准/拒绝”链接时显示自定义visualforce页面，而不是显示standrad Salesforce批准页面

---

如果可能的话，请告诉我如何实现这一点？

按照以下方法覆盖标准审批流程页面

创建自定义visualforce页面：从复制标准批准/拒绝页面开始

创建具有批准/拒绝/取消方法的控制器

使用Javascript创建主页组件，以覆盖Lead上的“批准/拒绝”按钮

在主页布局中添加此主页组件

视觉力页 主页组件

尝试
{
var pa=document.getElementById（“demoContainer”）.parentNode.parentNode；pa.style.display=“无”；
}
catch（err）{alert（'此网页上有错误='+err.description）；}
功能CustomApproval（）
{
尝试
{
var str=location.href；
var leadId=str.substr（str.indexOf（“.com/”）-0+5,15）；
var divid=leadId+“与流程相关的历史列表”和“主体”；
var Approvalprocessdiv=document.getElementById（divid）；
if（Approvalprocessdiv！=null）{
var originalHTML=Approvalprocessdiv.innerHTML；
var newHtml=originalHTML.replace（“/p/process/ProcessInstanceWorkitemWizardStageManager？”，“/apex/ProcessInstanceWorkitemWizard？LeadId=”+LeadId+”&'）；
Approvalprocessdiv.innerHTML=newHtml；
}
}
捕捉（错误）{提醒（错误）；}
}
var oldonload=window.onload；
if（typeof window.onload！=“函数”）
{
window.onload=oldonload；
}否则
{ 
window.onload=函数（）
