Your code is working for me. 您的代码对我有用。 Try it here. 在这里尝试。 http://jsfiddle.net/DLs7j/ That is the same exact code as yours. http://jsfiddle.net/DLs7j/这与您的代码相同。 Copy, pasted. 复制，粘贴。
Best 最好

You don't need getCmb, and you don't need to declare an extra element. 您不需要getCmb，也不需要声明额外的元素。
Use this instead: 使用此代替：
<html>
<head>
<script type="text/javascript">
function Expedisi(t)
{
var y=document.getElementById("txt");
y.value = t.value;
}
</script>
</head>
<body>
<select name="JENIS" id="cmb" data-role="slider" onChange="Expedisi(this);">
<option value="Suplier">Sup</option>
<option value="Expedisi">Exp</option>
</select>
<input type="text" name="BKIRIM" id="txt" value=""/>
</body>
</html>

You need to change the quotes around the script type tag. 您需要更改脚本类型标记周围的引号。 You are current using the ”” instead of ""; 您当前使用的是“”而不是“”； so change ”text/javascript” to "text/javascript". 因此将“ text / javascript”更改为“ text / javascript”。
