来自datepicker onSelect的jQuery ajax调用消失了文本框

[英]Jquery ajax call from datepicker onSelect disappears textbox

I have a textbox with datepicker jquery plugin. 我有一个带datepicker jquery插件的文本框。 When i select a date ,post ajax call is made and i want to return some data from database and textbox should remain on top of the page so that furthur requests can also be made. 当我选择一个日期时,将进行post ajax调用,并且我想从数据库返回一些数据,并且文本框应保留在页面顶部,以便也可以进行进一步的请求。

    <script>
        $(document).ready(function(){
        //create date pickers
            $("#datepicker").datepicker(
            { 
                changeMonth: true,
                changeYear: true,
                dateFormat: 'yy-mm-dd',
                onSelect: function(date)
                {
                    $.ajax({
                        type:"POST",
                        url:"seestuffs.php",
                        data:date,
                        success: function(result)
                        {
                              document.write(result);
                        }
                    });
                }
            });
        });
    </script>
    <body>
<p>Date: <input type="text" id="datepicker" name="date" /></p><br/>
    </body>

And here is my seestuffs.php 这是我的seestuffs.php

<?php 

if(isset($_POST['date']))
{
    $date = $_POST['date'];
    echo 'hello';

}


?>

But hello is not displayed on the page.Where am I going wrong!!Thanx in advance.. 但是你好并没有显示在页面上。我要去哪里错了!谢谢!

document.write will create a new document if called on a document that has already loaded. 如果在已加载的文档上调用document.write,则会创建一个新文档。 This is explained in this Question: JavaScript Document.Write Replaces All Body Content When Using AJAX . 在以下问题中对此进行了解释: 使用AJAX时,JavaScript Document.Write替换所有正文内容

So instead you need to add the result to the document either by appending a new node or using innerHTML eg: 因此,您需要通过添加新节点或使用innerHTML将结果添加到文档中,例如:

success: function(result) {
   $('body').append('<p>'+result+'</p>');
}
