Use ajax for this purpose. 为此使用ajax。
<html>
<head>
<title>Untitled Document</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$('#radioid').click(function() {
$('#txtDoorStyle').val($(this).val());
});
});
</script>
</head>
<body>
<input type="radio" id="radioid" value="Door Half Transom (011)" name="doorstyle">
<input type="text" value="" id="txtDoorStyle" name="txtDoorStyle" >
</body>
</html>>
you have two choices either two load this autocomplete options upfront in which case you store the data that you have retrieved from the dB in a hidden field after serializing the data to a string and in your javascript you parse it back to an array using str.split(",")
您有两个选择,或者两个都预先加载了此自动完成选项,在这种情况下,将数据串行化为字符串后,将从dB中检索到的数据存储在隐藏字段中,然后在JavaScript中使用
str.split(",")
将其解析回数组str.split(",")
or 要么
you could make an ajax request when the user starts typing and then retrieve the data as a string and then parse it to an array and then pass it to the autoComplete api. 您可以在用户开始输入内容时提出ajax请求,然后以字符串形式检索数据,然后将其解析为数组,然后将其传递给autoComplete api。 You can read about jquery ajax here
