Question

我正在尝试使用Javascript验证单选按钮。但我无法得到它。任何人都可以帮我解决这个问题。我附上了我的代码。感谢。

<form action="submitAd.php" method="POST" enctype="multipart/form-data" name="packages" onsubmit="return checkForm()">
    <div id="plans_pay">
            <input  type="radio" name="group1" id="r1" value="Office"  onchange="click_Pay_Office()"  style="float:left;margin-top:20px;font-size:72px;">
            <label style="float:left; margin-top:20px;" for="pay_office">At Our Office</label>
            <img style="float:left;margin-bottom:10px;"  src="images/Pay-at-office.png" />
          </div>
      <div id="plans_pay">
                    <input style="float:left;margin-top:20px;font-size:72px;" type="radio" name="group1" id="r2" value="HNB"  onchange="click_Pay_Hnb()">
                <label style="float:left; margin-top:20px;" for="pay_hnb">At Any HNB Branch</label>
               <img style="float:left;margin-bottom:10px;"  src="images/HNB.png" />
        </div>
</form>

的Javascript

function checkForm(){


    if( document.packages.pso.checked == false && document.packages.pso1.checked == false && document.packages.ph.checked == false && document.packages.ph2.checked == false && document.packages.ph3.checked == false  && document.packages.pl.checked == false && document.packages.p3.checked == false && document.packages.p4.checked == false && document.packages.p5.checked == false && document.packages.p6.checked == false ){

        alert('Please Select At Least One Package');
        return false;

    }
    if(  document.packages.pso.checked == false && document.packages.pso1.checked == false && document.packages.ph.checked == false && document.packages.ph.checked == false && document.packages.ph2.checked == false && document.packages.ph3.checked == false  && document.packages.pl.checked == false && document.packages.p3.checked == false  && document.packages.p4.checked == false  && document.packages.p5.checked == false && document.packages.p6.checked == false){

        alert('Please Select At Least One with the Advertise online option in premium package');
        return false;

    }
    if(document.getElementById('words').value==''){
        alert("Please Enter the Texts");
        return false;

    }

    if(document.getElementById('r1').checked==false && document.getElementById('r2').checked==false){
        alert("Please Select a Payment Method");
        return false;

    }


}

不要在事件 onsubmit 上的表单标记中调用 checkForm（），而是在提交按钮中更好地使用它

<input type="submit" name="submit" value="submit" onClick="return checkForm()" />

它会更好地工作并根据需要输出。
