我对表单提交和问题有疑问. onchange事件无法协同工作.当我更改下拉列表上的值时，事件viewroom()不会触发.有人可以帮我吗?代码如下

I have a question about form submit & onchange events not working together. When I change the value on the dropdown list the event viewroom() is not firing. Could anyone help me with this? The code is as follows

<script type="text/javascript">
function viewroom()
{
    alert(123);
}
</script>

<form id="myform" name="myform" action="joinroom.php" method="post">
<select name="viewroom" id="viewroom" onChange="viewroom()">
    <option value="1">Room1 </option>
    <option value="2">Room2 </option>
</select>
<input type="submit" onclick="this.form.submit()" value="Join room"><br>
</form>

推荐答案

您的函数名称与select的name和id冲突，只需为函数指定另一个名称即可.

Your function name conflicts with name and id of the select, just give another name to the function.
