<body :controller="content">
<select :change="@choose()" :duplex="@dx">
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
</select>
</body>
<script>
vm = avalon.define({
$id: 'content',
action:0,
dx: 'B',
choose: function() {
console.log(vm.dx);
}});
</script>
</html>
当选择A时, 打印的是B,
然后选择C,打印的是A.
在change事件中打印vm.dx始终是上一次select选择的值.
change事件就是这样子, 你应该用data-duplex-changed回调
