从PHP获取数据以使用HTML

标签： php ajax

我尝试了很多东西，但没有一个成功。我试图在选中框（选择拉资产中心数据）后更改评级选项。它获取php文件中的数据，但我不知道如何处理html文件中的数据。

数据 servername联系分类评级 Server1 Ray Production A. Server2 Eric非生产B

-

- 数据库：ipreservation


-

- 表acdata
的表结构
CREATE TABLE IF NOT EXISTS `acdata` (
  `servername` varchar(25) NOT NULL,
  `contact` varchar(20) NOT NULL,
  `classification` varchar(15) NOT NULL,
  `rating` varchar(4) NOT NULL 
) 
ENGINE=InnoDB DEFAULT
CHARSET=latin1;
-

- 转储表acdata
的数据
INSERT INTO `acdata` (`servername`, `contact`, `classification`,`rating`) 
VALUES ('Server1', 'Ray', 'Production', 'A'),
('Server2','Eric', 'Non-Production', 'B');
/ *！40101 SET CHARACTER_SET_CLIENT = @ OLD_CHARACTER_SET_CLIENT /; / ！40101 SET CHARACTER_SET_RESULTS = @ OLD_CHARACTER_SET_RESULTS /; / ！40101 SET COLLATION_CONNECTION = @ OLD_COLLATION_CONNECTION * /;

您的代码使用jQuery简化并正常工作，请在下面找到更新的代码

<html>
    <head>
        <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
        <script type="text/javascript" >
        $(document).ready(function(){
            var id = $('#existingserver').val();            
            $('#assetCenter').click(function(){
                var id = $('#textfield').val();
                $.get('servertest.php',{q:id}, function(htmlData){
                    $('#txtHint').html(htmlData);                    
                    $('#rating').val(htmlData); 
                });
