我需要在Jquery函数返回false后停止Button1_Click fire。这是我的代码......

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return x();" OnClick="Button1_Click" />
OnClick="Button1_Click" />
</div>
</form>
</body>

js文件
function x() {
alert('');
return false;
}
这是我生成的HTML文件

我也尝试过类似的链接:
Why doesn't returning false from OnClientClick cancel the postback
在这种情况下,通过jquery注册了一个单击事件的处理程序..我认为它不在我的情况下
ASP.NET OnClientClick="return false;" doesn't work
不应该有一个单击事件处理程序(通过jquery注册)返回true .whats意味着什么?这是否意味着我需要删除onClick函数...我不想这样做
我还尝试了其他建议的代码:
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="if (!x()) return
false;" OnClick="Button1_Click" />
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="javascript:return
x();"OnClick="Button1_Click" />
他们也没有工作
请建议

这对我有用......
.aspx page
<asp:Button id="btn" runat="server" Text="Button" onclientclick="if (!x()) { return false; }" onclick="btn_Click" />
<script type="text/javascript">
function x() {
return false;
}
</script>
更新 external.js
function x() {
var result = confirm("Sure");
if (result)
return true;
else
return false;
}
.aspx page
<form id="form1" runat="server">
<asp:Button id="btn" runat="server" Text="Button" onclientclick="if (!x()) { return false; }" onclick="btn_Click" />
</form>
<script src="external.js" type="text/javascript"></script>
希望它有所帮助.. !!

您还可以将所有代码放在单个文件中。直接从jQuery附加处理程序
jQuery(document).ready(function () {
AttachDeleteButtonHandler();
});
function AttachDeleteButtonHandler() {
var btnDelete = $("div[class='page']").find("table[id$='tblButtons']").find("input[id$='btnDelete']");
btnDelete.click(
function () {
return ConfirmDelete();
}
);
}
function ConfirmDelete() {
var msg = $('div[id="hdnElements"]').find('span[onclick*="translatedMsgText"]').text();
if (confirm(msg)) {
return true;
}
else {
return false;
}
}
