How to set form required in bootstrap

Introduce bootstrapValidator.js and bootstrapValidator.css files into the page with jquery and bootstrap

Then create a form form and add form controls. The form controls must have absolute Positioning, otherwise an error will be reported

<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>
Copy after login

Write a js file and verify the form through the js file:

$(function () {
            $("#form-test").bootstrapValidator({
                live: &#39;disabled&#39;,//验证时机,enabled是内容有变化就验证(默认),disabled和submitted是提交再验证
                excluded: [&#39;:disabled&#39;, &#39;:hidden&#39;, &#39;:not(:visible)&#39;],//排除无需验证的控件,比如被禁用的或者被隐藏的
                submitButtons: &#39;#btn-test&#39;,//指定提交按钮,如果验证失败则变成disabled,但我没试成功,反而加了这句话非submit按钮也会提交到action指定页面
                message: &#39;通用的验证失败消息&#39;,//好像从来没出现过
                feedbackIcons: {//根据验证结果显示的各种图标
                    valid: &#39;glyphicon glyphicon-ok&#39;,
                    invalid: &#39;glyphicon glyphicon-remove&#39;,
                    validating: &#39;glyphicon glyphicon-refresh&#39;
                },
                fields: {
                    text: {
                        validators: {
                            notEmpty: {//检测非空,radio也可用
                                message: &#39;文本框必须输入&#39;
                            },
                            stringLength: {//检测长度
                                min: 6,
                                max: 30,
                                message: &#39;长度必须在6-30之间&#39;
                            },
                            regexp: {//正则验证
                                regexp: /^[a-zA-Z0-9_\.]+$/,
                                message: &#39;所输入的字符不符要求&#39;
                            },
                            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: &#39;指定页面&#39;,
                                message: &#39;The username is not available&#39;
                            },
                            different: {//与指定文本框比较内容相同
                                field: &#39;指定文本框name&#39;,
                                message: &#39;不能与指定文本框内容相同&#39;
                            },
                            emailAddress: {//验证email地址
                                message: &#39;不是正确的email地址&#39;
                            },
                            identical: {//与指定控件内容比较是否相同,比如两次密码不一致
                                field: &#39;confirmPassword&#39;,//指定控件name
                                message: &#39;输入的内容不一致&#39;
                            },
                            date: {//验证指定的日期格式
                                format: &#39;YYYY/MM/DD&#39;,
                                message: &#39;日期格式不正确&#39;
                            },
                            choice: {//check控件选择的数量
                                min: 2,
                                max: 4,
                                message: &#39;必须选择2-4个选项&#39;
                            }
                        }
                    }
                }
            });
            $("#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
                $("#form-test").bootstrapValidator(&#39;validate&#39;);//提交验证
                if ($("#form-test").data(&#39;bootstrapValidator&#39;).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
                }
            });
        });
