Question

我正在尝试显示隐藏texbox并在选中单选按钮时验证文本框＆＃34;是＆＃34;。选中单选按钮＆＃34;否＆＃34;不应显示错误消息。显示/隐藏对我来说很好，但验证texbox对我不起作用。当单选按钮被选中时显示错误消息no并且文本框被隐藏。我是jquery的新手请帮助我。这是代码。

      $(function() {

      $("input[name='chkPassPort']").click(function () {
            if ($("#chkYes").is(":checked")) {
                $("#dvPassport").show();
            } else {
                $("#dvPassport").hide();
            }
        });


        $("#XISubmit").click(function(){
  var project1=document.forms["XIForm"]["project1"].value;
            var funding1=document.forms["XIForm"]["funding1"].value;
if(  project1==null || project1=="") {alert("Please enter Project title"); return false;}
    if(funding1==null || funding1=="") {alert("Please enter Funding Agency"); return false;}
document.getElementById("XIForm").submit();

            }); 

    }); 

<form name="XIForm" id="XIForm" method="POST" action="" style="margin-bottom:-10px;">
<input type="radio" id="chkYes" name="chkPassPort" value="Yes" />
    Yes
</label>
<label for="chkNo">
    <input type="radio" id="chkNo" name="chkPassPort" value="No"/>
    No
</label>
<div id="dvPassport" style="display: none">
        <table cellpadding="10px">
        <tr>
    <td style="width:250px">Project Title</td>
    <td style="width:250px">Funding agency</td>

    </tr>
    <br/>
    <tr>
    <td><input type="text" name="project1" id="project1"  style="width: 220px;border:solid 1px #0096ce;margin-right:40px;padding: 5px 3px; " maxlength="80"/></td>
    <td><input type="text" name="funding1" id="funding1"  style="width: 220px;border:solid 1px #0096ce;padding: 5px 3px;margin-right:28px; " maxlength="80"/></td>


        </tr>
</table></div>

Answer 1

      if ($("#chkYes").is(":checked"))
         {
           if(  project1==null || project1=="") {alert("Please enter Project title"); return false;}
           if(funding1==null || funding1=="") {alert("Please enter Funding Agency"); return false;}
          document.getElementById("XIForm").submit();
           }

提交前检查单选按钮。希望它有所帮助。

通过以下方法，您可以检查值

        var project1= $("#<%= project1.ClientID %>").val();
                        if(project1== "")
                        {
                        alert("Please enter a name");
                        }
                        else{
                            alert("Welcome: "+name);
                        }

        var funding1= $("#<%= funding1.ClientID %>").val();
                        if(funding1== "")
                        {
                        alert("Please enter a name");
                        }
                        else{
                            alert("Welcome: "+name);
                        }

如果你想单独验证隐藏和显示文本框，那么你可以在一个函数中获得这个验证并调用特定的函数

示例：

      function CheckProject1Text1()
      {
       var project1= $("#<%= project1.ClientID %>").val();
                        if(project1== "")
                        {
                        alert("Please enter a name");
                        }
                        else{
                            alert("Welcome: "+name);
                        }
    }
    function CheckFunding1Text1()
    {
     var funding1= $("#<%= funding1.ClientID %>").val();
                        if(funding1== "")
                        {
                        alert("Please enter a name");
                        }
                        else{
                            alert("Welcome: "+name);
                        }
    }

使用jquery检查单选按钮是否验证文本框
