Question

主要问题是当我选择现金单选按钮时，第一个字段必须是强制性的，如果我选择第二个按钮，那么检查字段必须是修饰的...
当我提交数据验证不起作用时，为该程序添加HTML代码

<form action="add_file.php" method="post" enctype="multipart/form-data" name="form4">
              <table width="400" align="center" cellspacing="10" >

      <tr>
        <td></td>

      </tr>
      <tr>
        <td style="width:200px;"><label class="label">Purchase Date:</label></td>
        <td><input type="text" name="Purchase_date" id="datepicker" class="button" /></td>
      </tr>

      <tr>
        <td style="width:200px;"><label class="label">Expanse Head:</label></td>
        <td><input type="text" name="Expanse_head" class="button" /></td>
      </tr>

      <tr>
        <td style="width::200px"><label class="label">Type of Payment:</label></td>
          <td><input type="radio" name="type" value="cash" />
            cash
            <input type="radio" name="type" value="cheque"/><label>
              cheque</label></td>

        </tr>

      <tr>
        <td style="width:200px;"><label class="label">Expanse Cash:</label></td>
        <td><input type="text" name="Expanse_cash" class="button" pattern="[0-9]+" required title="Please Enter Digits"/></td>
      </tr>

       <tr>
        <td style="width:200px;"><label class="label">Cheque No</label></td>
        <td><input type="text" name="cno" class="button" /></td>
      </tr>






        <tr style="margin-top:100px;">
        <td><label class="label">Bill</label></td>
        <td><input type="file" name="uploaded_file"  /></td>

      </tr>
       <tr style="margin-top:100px;">
        <td></td>
        <td><input type="submit" value="Save" onclick="return validate(this);" /></td>

      </tr>
      <tr>
      <td></td>

      </tr>


    </table>


          </form>



    <script>
    function validate(){
    if(document.form4.Purchase_date.value==""){alert("Please Enter Date");  return false;}
    if(document.form4.Expanse_head.value==""){alert("Please Enter Expanse Head");   return false;}

    /*if(document.form4.type.value=="1"){
        (document.form4.Expanse_cash.value=="")
            {alert("Please Enter value");   return false;}}
        else(document.form4.type.value=="cheque")
        {
            (document.form4.cno=="");
            {alert ("Please Enter Cheque No "); return false;}}*/

    if(document.form4.uploaded_file.value==""){alert("Please upload file"); return false;}

        }
    </script>

重写代码，希望这会有效!!

如果（document.form4.type.value == “的现金”）{

如果（document.form4.Expanse_cash.value == “”）{

alert("Please Enter value"); return false;

}

}

else if else （document.form4.type.value ==“check”）{

如果（document.form4.cno。的值 == “”）{

alert ("Please Enter Cheque No "); return false;}

}

否则{

提醒（“请选择付款方式!!”）;

}

面对验证时，我选择单选按钮
