关于提交按钮的问题
网页上有个提交按钮，我想实现用户一点提交按钮，然后该按钮就变为不可使用，提交成功，又可以使用了，这样如何实现？
[解决办法]
button1.enable = false
[解决办法]
<body onbeforeunload= "javascripot:return DisabledButton() "> <asp:Button ID= "btnSave " runat= "server " OnClientClick= "javascript:gBtnDisabled=this " OnClick= "btnSave_Click " Text= "保存 " /> <script> var gBtnDisabled = null; function DisabledButton() { if(gBtnDisabled!= null) { alert( "## "); gBtnDisabled.disabled = true; } } </script> 后台测试: protected void btnSave_Click(object sender, EventArgs e) { System.Threading.Thread.Sleep(3000); }
