方法一&＃xff1a;
在JS中使用button按钮的click方法
<script type&＃61;"text/Javascript">
function JSFun2()
{
document.getElementById("<%&＃61; btnTest4.ClientID %>").click();
}
</script>
function JSFun2()
{
document.getElementById("<%&＃61; btnTest4.ClientID %>").click();
}
</script>
方法二:
ClientScript.GetPostBackEventReference(btnTest2, "")
上面这行代码的返回值是一个string,"__doPostBack(&＃39;btnTest2&＃39;,&＃39;&＃39;)".
然后使用RegisterClientScriptBlock注册一下脚本.
string jscript &＃61; "function JSFun1(){" &＃43; ClientScript.GetPostBackEventReference(btnTest2, "") &＃43; "};";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", jscript, true);
