bootstrap如何设置表单必填-木庄网络博客

在有jquery和bootstrap的页面里引入bootstrapValidator.js和bootstrapValidator.css文件

然后建立一个form表单，添加表单控件，表单控件必须有绝对定位，不然会报错

<form action="" method="POST" role="form" id="form-test">
                <legend>Form title</legend>
  
                <div class="form-group">
                    <label for="">label</label>
                    <input type="text" class="form-control" id="" name="text" placeholder="Input field">
                </div>
  
  
  
                <button id="btn-test" class="btn btn-primary">Submit</button>
            </form>

编写js文件，通过js文件验证表单：

$(function () {
            $("#form-test").bootstrapValidator({
                live: 'disabled',//验证时机，enabled是内容有变化就验证（默认），disabled和submitted是提交再验证
                excluded: [':disabled', ':hidden', ':not(:visible)'],//排除无需验证的控件，比如被禁用的或者被隐藏的
                submitButtons: '#btn-test',//指定提交按钮，如果验证失败则变成disabled，但我没试成功，反而加了这句话非submit按钮也会提交到action指定页面
                message: '通用的验证失败消息',//好像从来没出现过
                feedbackIcons: {//根据验证结果显示的各种图标
                    valid: 'glyphicon glyphicon-ok',
                    invalid: 'glyphicon glyphicon-remove',
                    validating: 'glyphicon glyphicon-refresh'
                },
                fields: {
                    text: {
                        validators: {
                            notEmpty: {//检测非空,radio也可用
                                message: '文本框必须输入'
                            },
                            stringLength: {//检测长度
                                min: 6,
                                max: 30,
                                message: '长度必须在6-30之间'
                            },
                            regexp: {//正则验证
                                regexp: /^[a-zA-Z0-9_\.]+$/,
                                message: '所输入的字符不符要求'
                            },
                            remote: {//将内容发送至指定页面验证，返回验证结果，比如查询用户名是否存在
                                url: '指定页面',
                                message: 'The username is not available'
                            },
                            different: {//与指定文本框比较内容相同
                                field: '指定文本框name',
                                message: '不能与指定文本框内容相同'
                            },
                            emailAddress: {//验证email地址
                                message: '不是正确的email地址'
                            },
                            identical: {//与指定控件内容比较是否相同，比如两次密码不一致
                                field: 'confirmPassword',//指定控件name
                                message: '输入的内容不一致'
                            },
                            date: {//验证指定的日期格式
                                format: 'YYYY/MM/DD',
                                message: '日期格式不正确'
                            },
                            choice: {//check控件选择的数量
                                min: 2,
                                max: 4,
                                message: '必须选择2-4个选项'
                            }
                        }
                    }
                }
            });
            $("#btn-test").click(function () {//非submit按钮点击后进行验证，如果是submit则无需此句直接验证
                $("#form-test").bootstrapValidator('validate');//提交验证
                if ($("#form-test").data('bootstrapValidator').isValid()) {//获取验证结果，如果成功，执行下面代码
                    alert("yes");//验证成功后的操作，如ajax
                }
            });
        });
