Question

所以我尝试提交表单数据，但不希望页面更改/刷新。同时我希望在完成后弹出一个jquery对话框。

这是我原来的：

 <script>
  $( function() {
    $('#dialog-message').dialog({
      autoOpen: false,
      title: 'Basic Dialog'
    });



 $( "#subbutton" ).click(function( event ) {
       event.preventDefault();

       $.post("formaction.php",function(){
         $('#dialog-message').dialog('open');
         return false;
     });
 });
  });
  </script>

这会向数据库提交空白数据，但会插入新行。删除event.preventDefault（）;提交所有数据但页面更改为formaction.php。

我试图进行投票，但我不确定如何做到正确。我会在不同的计算机上提供一些代码。

$( function() {
    $('#dialog-message').dialog({
      autoOpen: false,
      title: 'Basic Dialog'
    });

  });

    $( "#subbutton" ).click(function( event ) {
      $('#dialog-message').dialog('open');

      event.preventDefault();

      $(function poll(){

        setTimeout( function(){

          $.ajax({
            type:'POST',
            dataType: 'json',
            url:'formaction.php',
            success: function(data){

            },
            complete: poll
          }),
        },
        5000);

      })


      /*
      $.post("formaction.php",function(){
      return false;
    });
    event.preventDefault();
    */
  });
  poll();

Answer 1

您的ajax $.post()函数缺少要插入的数据。

添加它的最简单方法是序列化表单：

...
event.preventDefault();

$.post("formaction.php", $('form').serialize(), function(){
     $('#dialog-message').dialog('open');
});

现在form元素中的所有字段都将添加到帖子中。如果您有多个表单，可以使用表单的ID来获得正确的表单：

$.post("formaction.php", $('#your_form').serialize(), function(){
     $('#dialog-message').dialog('open');
});

Answer 2

使用ajax。

$.ajax({
          type: "POST",
          url:"<?php yourpage.php;?> ",
          data:your data,
          success: function(html){
           //show your message
          }
    });

Answer 3

您将需要使用：success回调函数。

$.post( "test.php", { name: "John", time: "2pm" })
  .done(function( data ) {
    alert( "Data Loaded: " + data );
  });

Answer 4

有一个简单的解决方案可以停止重定向。更改按钮的类型（#subbutton）添加属性{ "name": "creationTimestamp", "type": "date", "cellFilter": "date:'MM/dd/yyyy HH:MM:ss.SSS'" }

阻止页面刷新并提交表单数据
