Question

我正在使用php表单，其中表单正在使用jquery进行验证。现在以这种形式有单选按钮列表。如果用户单击“是”，则不会验证与该单选按钮列表相关的文本框。如果用户单击否，则应该验证与该单选按钮列表相关的文本框..

但现在问题是我之前的开发人员验证了这样的表格：

jQuery(".required").each(function(){
    var vlr = jQuery(this).val();
    if(vlr == ''){
        alert("Value not to be blank");
        jQuery(this).focus();
        e.preventDefault();
        e.stopPropagation();
        return false;
    }
});

单选按钮列表的Html部分

<tr>
      <td class="css-gen7 paragraph">Is premium paid? 
          <input name="is_premium_016" value="yes" class="required"  type="radio">Yes
          <input name="is_premium_016" value="no" class="required"  type="radio">No
      </td>
      <td class="css-gen7">if not,why not?  <input name="if_not_017" type="text" class="required" style="width:30%"></td>
    </tr>

此代码验证完整表单如何捕获单选按钮列表值，如果用户勾选是，我如何停止验证文本框？

我希望你明白我的意思。

试试这个：

$('#search_form').submit(function() {
    if($('#fepUserIDValue').attr("checked") == "checked" && $('#inquiry_date').val() == '') {
       alert('Required field missing');
       return false;
    }
});

所以，只有在用户点击否时才要执行验证？那是对的吗？这里有一个可能对您有用的代码：假设上面的假设是正确的。

<强> JAVASCRIPT

        <script type="text/javascript">
            ;                           // CLOSE OFF ANY UNCLOSED JS TAGS... IF ANY ;-)
            jQuery.noConflict();        // ADD THE noConflict() METHOD, IN CASE YOU ARE USING OTHER LIBRARIES THAT MAKE USE OF THE $ SYMBOL
            (function ($) {
                $(document).ready(function(e) {
                    // CREATE VARIABLES TO HOLD THE FORM, RADIO-BUTTON & TEXT-FIELD JQUERY OBJECTS
                    var isPremiumRadio      = $("input[name=is_premium_016]");
                    var ifNotWnyNot         = $("input[name=if_not_017]");
                    var controlForm         = $("form[name=name_of_your_form]");    //<== PLEASE; PUT THE REAL NAME OF YOUR FORM IN THE STEAD OF "name_of_your_form"

                    controlForm.on("submit", function(evt){
                        var theForm         = $(this);

                        evt.preventDefault();
                        evt.stopPropagation();

                        $(".required").each(function(){
