所以我试图提交表单数据，但不希望页面更改/刷新。同时，我希望在完成时弹出一个jquery对话框。
这是我的原文:
<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>
向DB提交空白数据，但它确实插入了新行。删除event.preventDefault ();提交除页面更改外的所有数据到form .php .
我试着做民意调查，但我不确定如何做得正确。我将在几分钟内提供该代码，因为它在另一台计算机上。
$( 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();
添加表单以获取更多细节

您的ajax $.post()函数缺少要插入的数据。
最简单的添加方法是序列化表单:
...
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，您可以使用表单的id来获取正确的表单:
$.post("formaction.php", $('#your_form').serialize(), function(){
$('#dialog-message').dialog('open');
});
使用ajax。
$.ajax({
type: "POST",
url:"<?php yourpage.php;?> ",
data:your data,
success: function(html){
//show your message
}
});
你将需要使用:success回调函数。
$.post( "test.php", { name: "John", time: "2pm" })
.done(function( data ) {
alert( "Data Loaded: " + data );
});
有一个简单的解决方案来停止重定向。改变按钮的类型(#subbutton)添加一个属性type="button"
