遍历 div 内的输入

问题描述

我正在尝试遍历通过 jQuery 放置在特定 div 上的所有输入，但没有响应.我无法使用警报查看输入的值.我究竟做错了什么 ?

I'am trying to iterate through all inputs which are placed on a specific div via jQuery, but there is no response. I can't see the values of inputs by using alert. What am I doing wrong ?

<form id="internshipStage2Form" method="POST" action="form2.php">
    <center>
        <table id="studentInformation" border="1">
            <caption style="color:#f00;">Student(Trainee) Information</caption>
            <tr>
                <td valign="middle" align="center">

                </tr>
            </table>
        </div>
        <h4 style="color:#f00;">
            I agree the terms.
        </h4>
        <input id="stuDecCheckBox" type="checkbox" name="stuDecCheckBox" /></br>
        <input id="sendButton" type="submit" name="sendButton2" value="SEND FOR APPROVEMENT"/>
    </center>
</form>

JS

$('#companyInfo').children('input').each(function () {
    alert(this.value);
});

如有任何帮助，将不胜感激.

Any help would be appriciated.

推荐答案

您的输入不是 #companyInfo 的子级.只需这样做:

Your inputs are not children of #companyInfo. Just do this:

$('#companyInfo input').each(function () {
    alert(this.value);
});
