在 jquery 插件中它应该能够直接验证，但我找不到解决方案。

我检查： http: //jqueryvalidation.org/documentation但在那里找不到答案。

如果字段为空，则应显示“必填”。但在我的情况下，我必须填写一些文本，转到另一个字段并返回到原始字段，然后一旦我删除仍然存在的文本，我就会得到“必填”。

这是默认情况还是我可以更改此行为？

这是我的代码：

<?php include("osb.php");?>
<script type = "text/javascript">
 $(function(){




$('#submit').click(function(){



$.ajax({

        url: 'osb.php',
        type: 'POST',
        data: $('#form1').serialize(),
        success: function(result){
             $('#response').remove();
             $('#container').append('<p id = "response">' + result + '</p>');
             $('#loading').fadeOut(500);

           }

     });         

});
});

</script>

您可以使用onfocusout参数来实现这一点。

基于jQuery 验证插件文档：

onfocusout
在模糊时验证元素（复选框/单选按钮除外）。如果未输入任何内容，则跳过所有规则，除非该字段已被标记为无效。

只需添加onfocusout: true到您的验证参数。

$("#form1").validate({
    rules: {
        'name':         {required: true},
        'country':      {required: true,},
        'email':        {required: true, email: true},
        'website':      {url: true},
        'nameorg':      {required: true,},
        'price':        {required: true, number: true},
        'description':  {required: true,},
        'wanted':       {required: true,},
        'expectation':  {required: true}
    },
    messages: {
        'name': "Required",
    },
    submitHandler: function (form) {
        alert('is good');
        return false;
    },
    onfocusout: true
 });
