Question

您好我想知道如果只使用jquery在表单中填充或不填写所有必填字段我试过这个

＆＃13;

 $('#form').find('input,select, textarea').each(function(){
                       if(!$(this).prop('required')){
                           console.log("NR");
                       } else {
                           console.log("IR");
                       }
                   });
                   
                   //but from this I got to know about only fields with input type or select and textarea, I am not able to know about the fields with uses some third party here the uib-rating

<div id="form">
<div class="row" id="D_1">
 First name:<br>
  <input type="text" name="firstname" value="ab" ng-model="fname" required>
  <br>
  Last name:<br>
  <input type="text" name="lastname" value = "" required = "fname === 'abc'">
 
</div>
<div class="row" id="D_2">
 notes:<br>
  <input type="text" name="notes" >
</div>
<div class="row" id="D_3">
 <textarea name="tarea"></textarea>
 <span uib-rating titles=[] ng-model="" max="5" name="rating"
                on-leave="overStar = null"  ng-required="fname === 'abc'"></span>
</div>
</div>

＆＃13;

但是从这开始我只知道输入类型或select和textarea的字段，我无法知道使用某些第三方或某些内置指令的字段（这里是uib-rating）请帮我检查这些领域的必要性

＆＃13;

//I have already tried this:
 $('.form-field').each(function() {
    if ( $(this).val() === '' )
        isValid = false;
  });

＆＃13;

但不适合第三方

Answer 1

如果您只是想知道是否所有这些都已填满：

function validateForm() {
  var isValid = true;
  $('#form').find('input:required,select:required, textarea:required').each(function() {
    if ($(this).val() === '')
      isValid = false;
  });
  return isValid;
}

<强>样本

＆＃13;

function validateForm() {
  var isValid = true;
  $('#form').find('input:required,select:required, textarea:required').each(function() {
    if ($(this).val() === '')
      isValid = false;
  });
  return isValid;
}

$(".validate").click(function() {
  console.log(validateForm());
});

要检查表单中的输入是否需要输入带有某些指令
