当表单发生更改时，防止 bootstrap-3 模态关闭
我试图阻止 bootstrap-3 模式在模式内的表单发生更改时在没有警告的情况下关闭.但是，当我收听模态框触发的事件并返回 false 时，它将阻止模态框永远关闭.这是我的代码:
I'm trying to prevent the bootstrap-3 modal from closing without warning when there are changes made to the form inside the modal. However when I listen to the events fired by the modal and return false it will prevent the modal from closing ever. Here's my code:
$(function() {
$('body').live('shown.bs.modal', '#quickbutton-create', function () {
$(this).find('#quickbutton-create form').monitor();
});
$('body').live('hide.bs.modal', '#quickbutton-create', function () {
if ($(this).find('#quickbutton-create form').monitor('has_changed')) {
if (!confirm('Are you sure?')) {
return false;
}
}
});
});
简而言之，在这种情况下；如何防止模态仅关闭一次.
So in short, in this case; how do I prevent the modal from closing just this once.
推荐答案
好吧，我想通了，我需要 event.preventDefault() 而不是 return false
Ok so I figured it out, instead of return false I needed to event.preventDefault()
jsfiddle 在这里:http://jsfiddle.net/ACYBv/1/

$(function() {
$('.modal').on('shown.bs.modal, loaded.bs.modal', function(e) {
// set form state
$(this).data('form-data', $(this).find('form').serialize());
});
$('.modal').on('hide.bs.modal', function(e) {
// check if the form data was changed since the modal was openened
if($(this).data('form-data') != $(this).find('form').serialize()) {
if(!confirm('you sure??')) {
e.preventDefault();
}
}
});
});
