各位大神,如何自动获取input值

“菜菜菜鸟”有一个刷卡器,当不同的工卡放在上面时,点击“卡号”后,会出现工卡卡号,现在想将工卡放在刷卡器上时,不用点击“卡号”,自动在网页上出现工卡卡号,且三秒钟自动刷新一次,哪位大神帮帮“菜菜菜鸟”啊?谢过了 现在代码如下: (js部分) function GetCardID() { var iRet = CardIO.ReadCardID(); document.getElementById("retResult").value = ''; document.getElementById("retContent").value = ''; document.getElementById("retResult").value = iRet; if( iRet == 0 ) { document.getElementById("retContent").value = CardIO.GetCardID(); } else if( iRet == 2 ) { document.getElementById("retContent").value = '未发现卡片!'; } else if( iRet == 3 ) { document.getElementById("retContent").value = '读卡信息错误!'; } } (html部分) <form method="get" action=" "> 返回数值: <input size = "20" type="text" value="" id="retResult"></input> <br/> 返回结果: <input size = "20" type="text" name=" " id="retContent" value=""></input></form>

是否有更好/更有效的方法来处理这个JSON数组?

重复自我处理表格

<div class="post-text" itemprop="text"> <p>My question is over creating a self-processing form that inserts to a database and then refreshes, incrementing arrays to change relevant info in the form.

The user selects a template name from a select menu, then it queries the database for that template, then returns the result to a variable.
