I'm using a checkbox and I want people to be able to check/uncheck it.
However, when they uncheck it, I'm using a jQueryUI modal popup to confirm that they really want to do that. Thus they can click OK or Cancel, and I want my checkbox to be unchecked only if they click OK.
That's why I would like to catch the uncheck event to prevent the checkbox from being visually unchecked, and uncheck it myself programmatically if the user happens to click on OK.
我怎么能这么做呢?
PS: I know I could re-check it after if the user clicks on Cancel but that would trigger the check
event which I do not want.
$("#checkboxID").on("click", function (e) {
var checkbox = $(this);
if (checkbox.is(":checked")) {
// do the confirmation thing here
e.preventDefault();
return false;
}
});
