Question

我有这个样本：

代码HTML：

<form class="add-patient">
  <fieldset style="display: block;">
          <label for="new_exam">New exam</label>
          <input type="text" name="new_exam" id="new_exam" value="">
  </fieldset>
  <fieldset style="display: block;">
          <label for="x_ray">X ray</label>
          <input type="text" name="x_ray" id="x_ray"  value="">
  </fieldset>
  <input type="button" class="btn btn-submit" onclick="sendForm();" value="Create report">
</form>

CODE JS：

 function sendForm() {
        var status_form = false;
        $(".add-patient input").each(function(){
           if($(this).val() == ""){
             status_form = true;
           }
        });
        console.log(status_form);
        var createdBy = jQuery('#created_by').val();

        if( status_form )
        {
            alert('Fill at least one field');
        }else{
            alert("now it's ok");
        }
 }

我想检查一下...如果输入完成后显示消息＆＃34;它;好的＆＃34; ...否则显示另一条消息可能意味着代码清楚他们想做什么。

你可以帮我解决一下这个问题吗？

提前致谢！

的输入元素的长度

试试这个：

''

function sendForm() {
  var elem = $(".add-patient input[type='text']");
  var count = elem.filter(function() {
    return !$(this).val();
  }).length;
  if (count == elem.length) {
    alert('Fill at least one field');
  } else {
    alert("now it's ok");
  }
}

如何检查至少一个输入是否完成？
