Ajax成功:{return false;}

Question

我想false从完成$.ajax时返回success:

$.ajax({
    url: '' + $website_url + 'queries/voorraad_berekenen.php',
    type: 'post',
    data: {
        aantal: $(this).parent('form').children('.quantity').val(),
        item_number_1: $(this).parent('form').children('.item_number_1').val()
    },
    success: function(result) {
        return false;
    }
});

这不起作用.有工作吗？

从你的帖子我想你调用一个函数包含$.ajax()并尝试return false该函数.但你不能这样做,因为AJAX是异步的.

最好从ajax成功函数调用一个函数,如下所示:

$.ajax({
    url: '' + $website_url + 'queries/voorraad_berekenen.php',
    type: 'post',
    data: {
        aantal: $(this).parent('form').children('.quantity').val(),
        item_number_1: $(this).parent('form').children('.item_number_1').val()
    },
    success: function(result) {
        var returned = true;
        if(some_condition_not_satisfied) {
          returned = false;
        } else {

        }
        // call a function
        calledFromAjaxSuccess(returned);
    }
});

function calledFromAjaxSuccess(result) {
  if(result) {
    alert('TRUE');
  } else {
    alert('FALSE');
  }
}
