推荐答案

你的文本框id具有与脚本中提到的不同的值（txtOther）。

尝试更改 this.form ['other'] to this.form ['txtOther']



希望这会对你有所帮助。

Hi,

You textbox id has different value(txtOther) other than mentioned in the script.
Try to change this.form['other'] to this.form['txtOther']

Hope this helps you a bit.

<script type="text/javascript">

（document）.ready（function（）{

(document).ready(function () {
