Question

我创建了带有2个复选框的页面，提交和重置按钮作为附加图像

enter image description here

如果我点击单选按钮，它将显示隐藏的文本区域。

enter image description here

如果我选中这两个复选框并单击提交，它将正常工作。但是，如果我只点击其中一个复选框并单击“提交”，那么它将无法正常工作。

是否可以帮助我如何通过只选择一个复选框来提交查询？

我的request_to_approve.php代码是

<html>

<script type="text/javascript">
function checkValue()
{

if(document.getElementById("reject").checked == true)
 {
   document.getElementById('xtraInfo').style.display='block';
   document.getElementById('xtraInfo1').style.display='block';
   document.getElementById('xtraInfo2').style.display='block';
   document.getElementById('xtraInfo3').style.display='block';
   document.getElementById('xtraInfo4').style.display='block';
   document.getElementById('xtraInfo5').style.display='block';

   document.getElementById('xtraInfo3').style.display='none';
   document.getElementById('xtraInfo4').style.display='none';
   document.getElementById('xtraInfo5').style.display='none';
 }
}

function checkswcr()
{

if(document.getElementById("swcr").checked == true)

   document.getElementById('otherInfo').style.display='block';
   document.getElementById('otherInfo1').style.display='block';
        if(document.getElementById("reject").checked == false)

Answer 1

function checkswcr(){   
        var swcrInfo = document.getElementById('swcrInfo');    
        swcrInfo.style.display == 'block' ? swcrInfo.style.display = 'none' : swcrInfo.style.display = 'block';
    }

Demo

Answer 2

好吧创建一个像数字一样的隐藏字段，在第一个复选框上存储一个值click..attach你想要的功能。在第二个复选框上单击存储不同的值和函数，如果两个复选框都已单击，则将第三个值存储在同一个隐藏字段中。隐藏字段的值将准确指示如何处理click.hope它应该工作

选择复选框显示textarea。如果未选中，则textarea值应为空
