Textarea使用jQuery / MySQL刷新

问题描述：

OK so let's say I have a textarea on the top of my browser and a text input box on the bottom. I want to connect a MySQL database and also whatever I type in the input box to appear in the text area. Sorta like a text RPG...

I know PHP, MySQL, good AJAX, and little jQuery. I just want to know how this is achieved. Thank you.

好的，假设我的浏览器顶部有一个textarea，底部有一个文本输入框。我想连接一个MySQL数据库，以及我输入框中输入的任何内容，以显示在文本区域中。 Sorta就像文本RPG ... p>

我知道PHP，MySQL，优秀的AJAX和小jQuery。我只是想知道这是如何实现的。谢谢。 p> div>

You can do something like this (the code below sends input text to php script which connects to database, does whatever you want it to do and prints a text to be displayed in text area) :

$("#update_btn").click(function() {
    var txt = $.ajax({
    url: 'your_file.php',
    async: true, // or false, depends on your needs
    type:'POST',
    data:({new_text:$('#input_box_1').val()})
     }).responseText;

     $('#txt_area_1').val(txt);
    });

To access new_text variable in php script, use $new_text = $_POST["new_text"]
