最近项目中一直在用 Jquery validation 做校验,结合bootstrap 和 jquery form 感觉效果不错。但是remote验证的缓存问题让我头痛了很久,几乎就像放弃这款插件了。

基于Bootstrap jQuery.validate Form表单验证实践项目结构 :

举例说明:

现有学校,年级,班级实体

github 上源码地址:

在同一学校下不能有相同的年级,在同一年级下不能有相同的班级

1、form 表单代码[html]

以同一学校下不能有相同年级为例,在验证的时候用remote方式:

复制代码 代码如下:

JS

<!DOCTYPE html> 
<html> 
    <head> 
        <title>Bootstrap Form Template</title> 
        <meta charset="utf-8" /> 
        <meta name="viewport" content="width=device-width, initial-scale=1.0"> 
        <link rel="stylesheet" type="text/css" href="plugins/bootstrap/css/bootstrap.css"/> 
    </head> 
    <body> 
        <div class="container"> 
            <h1 class="text-center text-danger">Form 示例</h1> 
            <form role="form" class="form-horizontal" action="javascript:alert('验证成功,可以提交.');" method="post">

                    </div> 
                </div> 
                <div class="form-group"> 
                    <label class="control-label col-md-2">Gender</label> 
                    <div class="col-md-10">

                            gril </label> 
                    </div> 
                </div> 
                <div class="form-group"> 
                    <label for="hobby" class="control-label col-md-2">Hobby</label> 
                    <div class="col-md-10"> 
                        <div class="checkbox"> 
                            <label> 
                                <input type="checkbox" name="hobby" value="Music">

                </div> 
                <div class="form-group"> 
                    <label for="sel" class="control-label col-md-2">Select</label> 
                    <div class="col-md-10"> 
                        <select multiple="" id="sel" name="sel" class="form-control"> 
                            <option value="1">1</option>

                </div> 
            </form> 
        </div> 
        <script src="plugins/jquery-1.11.1.js" type="text/javascript" charset="utf-8"></script> 
        <script src="plugins/bootstrap/js/bootstrap.js" type="text/javascript" charset="utf-8"></script> 
        <script src="plugins/jquery-validation/dist/jquery.validate.js" type="text/javascript" charset="utf-8"></script>

        <script type="text/javascript" charset="utf-8"> 
            MyValidator.init(); 
        </script> 
    </body> 
</html> 

复制代码 代码如下:

需要引用jquery.js,bootstrap.js,jquery.validate.js 库

"gradeId" : {
required : true,
min : 0,
remote: {
url: "gradeManager-checkGrade.action",
type: "post",
dataType: "json",
data: {
'gradeId' : function() {
return $("#gradeId").val();
},
'schoolId' : function() {
return $("#schoolId").val();
}
}
}
}

2、form.js 代码[javascript]

HTML

复制代码 代码如下:

复制代码 代码如下:

var MyValidator = function() { 
    var handleSubmit = function() { 
        $('.form-horizontal').validate({ 
            errorElement : 'span', 
            errorClass : 'help-block', 
            focusInvalid : false, 
            rules : { 
                name : { 
                    required : true 
                }, 
                password : { 
                    required : true 
                }, 
                intro : { 
                    required : true 
                } 
            }, 
            messages : { 
                name : { 
                    required : "Username is required." 
                }, 
                password : { 
                    required : "Password is required." 
                }, 
                intro : { 
                    required : "Intro is required." 
                } 
            }, 
            highlight : function(element) { 
                $(element).closest('.form-group').addClass('has-error'); 
            }, 
            success : function(label) { 
                label.closest('.form-group').removeClass('has-error'); 
                label.remove(); 
            }, 
            errorPlacement : function(error, element) { 
                element.parent('div').append(error); 
            }, 
            submitHandler : function(form) { 
                form.submit(); 
            } 
        }); 
        $('.form-horizontal input').keypress(function(e) { 
            if (e.which == 13) { 
                if ($('.form-horizontal').validate().form()) { 
                    $('.form-horizontal').submit(); 
                } 
                return false; 
            } 
        }); 
    } 
    return { 
        init : function() { 
            handleSubmit(); 
        } 
    }; 
}(); 

<div class="control-group">
<label class="control-label" for="schoolId">学校</label>
<div class="controls">
<s:select name="schoolId" list="schools" listKey="schoolId"
listValue="schoolName" headerKey="-1" headerValue="请选择学校"></s:select>
</div>
</div>

效果 :

<div class="control-group">
<label class="control-label" for="gradeId">年级</label>
<div class="controls">
<s:select name="gradeId" list="grades" listKey="gradeId"
listValue="gradeName" headerKey="-1" headerValue="请选择年级"></s:select>
</div>
</div>
