还有我的js：
function confirmingChange() {
$.confirm({
'title': 'Confirm',
'message': 'Are you sure?',
'buttons': {
'Yes': {
'action': function () {
__doPostBack(document.getElementById('processado'), '');

You need onchange instead of OnCheckedChanged and return true if you want postback and false otherwise.
您需要 onchange 而不是 OnCheckedChanged 并且如果您想要回发则返回 true 否则返回 false 。
<asp:CheckBox ID="processado" runat="server" onchange="return javascript:confirmingChange();"
OnCheckedChanged="ServerSideEventHandlerHere" AutoPostBack="true" />

For calling javascript you have to use "onchange" and you have to use "return".
要调用 javascript，您必须使用“ onchange”并且您必须使用“ return”。
onchange="return javascript:confirmingChange(); "
onchange="返回 javascript:confirmingChange();"
