asp.net的button OnClientClick
1.前台调用的方法脚本方法不能写在jquery的document加载事件中
2.bt.OnClientClick = "aa()"; 以示警戒
aspx
<html >
<head runat="server">
<title></title>
<script src="jquery-1.8.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
function aa() {
alert("ddd");
return false;
}
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<%-- <asp:TextBox ID="tt" runat="server"></asp:TextBox>--%>
<asp:Button ID="bt" runat="server" />
</div>
</form>
</body>
</html>
html显示页面为
<html xmlns="http://www.w3.org/1999/xhtml"> <head><title> </title> <script src="jquery-1.8.0.min.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { function aa() { alert("ddd"); return false; } }); </script> </head> <body> <form method="post" action="文本框防止脚本注入.aspx" id="form1"> <div class="aspNetHidden"> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwULLTE0MDM4MzYxMjMPZBYCAgMPZBYCAgMPDxYCHg1PbkNsaWVudENsaWNrBQRhYSgpZGRkO7QxsMXoZyDAWiqQcvix7EsQ5f10wiWs6IWc4PvUxUg=" /> </div> <div class="aspNetHidden"> <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWAwLnp4jnAgLM79rvDAK+79rvDNfOH3++q+4UyZXmsvQSNdBxOnqY15GA0gkV0vGIjXb2" /> </div> <div> <input name="tt" type="text" id="tt" /> <input type="submit" name="bt" value="" onclick="aa();" id="bt" /> </div> </form> </body> </html>
