javascript - 为什么BootstrapValidator不起作用？

我是Web开发的新手，在这里我知道这个问题很小，但是即使过了两天，我仍然找不到它。大家可以看看这段代码并指出我的错误吗？

我的代码ID here @ JSFiddle
谢谢

的HTML

<form id="registerForm" action="\register" method="post">
    <div class="form-group">
        <input class="form-control" type="text" name="email" placeholder="Email">
    </div>
    <div class="form-group">
        <input class="form-control" type="password" name="pass1" placeholder="Password">
    </div>
    <div class="form-group">
        <input class="form-control" type="password" name="pass2" placeholder="Confirm Password">
    </div>
    <button class="btn btn-primary" type="submit">Signup</button>
</form>

JS

$(document).ready(function () {
    $('.registerForm').bootstrapValidator({
        message: 'This value is not valid',
        feedbackIcons: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            email: {
                validators: {
                    notEmpty: {
                        message: 'The email is required and cannot be empty'
                    },
                    emailAddress: {
                        message: 'The input is not a valid email address'
                    }
                }
            },
            pass1: {
                validators: {
                    identical: {
                        field: 'pass2',
                        message: 'The password and its confirm are not the same'
                    }
                }
            },
            pass2: {
                validators: {
                    identical: {
                        field: 'pass1',
                        message: 'The password and its confirm are not the same'
                    }
                }
            }
        }

    });
});

最佳答案

要通过ID获取节点，请使用：$('#registerForm')。如果通过$('.registerForm')获取，则JS将在registerForm标记中查找类<form>。

阅读jQuery API是防止此类错误的好方法。
