只需要在 vue 中引入即可：

import graceChecker from "../../../common/graceChecker.js"

使用方式如下：

			formSubmit: function(e) {
				console.log('e = ', e);
				console.log('form发生了submit事件，携带数据为：' + JSON.stringify(e.detail.value))
                //定义表单规则
                var rule = [
                    {name:"nickname", checkType : "string", checkRule:"1,3",  errorMsg:"姓名应为1-3个字符"},
                    {name:"gender", checkType : "in", checkRule:"男,女",  errorMsg:"请选择性别"},
                    {name:"loves", checkType : "notnull", checkRule:"",  errorMsg:"请选择爱好"}
                ];
                //进行表单检查
                var formData = e.detail.value;
                var checkRes = graceChecker.check(formData, rule);
                if(checkRes){
                    uni.showToast({title:"验证通过!", icon:"none"});
                }else{
                    uni.showToast({ title: graceChecker.error, icon: "none" });
                }
			}
