只需要在 vue 中引入即可:文章来源:https://www.toymoban.com/news/detail-691022.html
import graceChecker from "../../../common/graceChecker.js"
使用方式如下:文章来源地址https://www.toymoban.com/news/detail-691022.html
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" });
}
}
