如何在AJAX事件结束之前暂停提交事件？

Question

我有一份表格和一份提交.如果有东西被填满,在提交之前我想确保它的价值很高(用ajax),如果是的话,那么我只能让它继续下去.所以,

$('#contact').submit(function() {
  // ajax
  $.ajax({
    type: 'POST',
    url: $(this).attr('ajaxgetaccommodationsbyemail'),
    success: function(answer) {
        here a popup window opens, which waits  until I press YES or NO
    },
    async: false
  });

   this is when return TRUE or FALSE
   there should be something like
   do while (popupWindowClosed)
   so $.when is not an option

});

您可以使用jQuery阻止提交,然后实际调用本机提交以发送表单

$('#contact').on('submit', function(e) {

    e.preventDefault();

    var form = this;

    $.ajax({
        type: 'POST',
        url: $(this).attr('ajaxgetaccommodationsbyemail'),
        success: function(answer) {
             popup(function(yesorno) {

                 if (yesorno) {
                     form.submit();
                 }

             });
        }
    });
});

和async:false删除,因为你应该永远不会做syncronous阿贾克斯.
