ElementUI表单验证validate和validateField的使用及区别
作者：roouzenn
Element-UI作为前端框架,最常使用到的就是表单验证,下面这篇文章主要给大家介绍了关于ElementUI表单验证validate和validateField的使用及区别,文中通过实例代码介绍的非常详细,需要的朋友可以参考下

传参及一些具体的直接点上边官网连接
这里我主要说一下实际项目中的使用
validate 会校验表单的整个属性,只要你给这个字段设置上了rule
this.$refs.表单名称.validate(async (valid) => {
if (!valid) {
//检验不通过走这里
return;
}
//校验通过走这里
}validateField 有些时候我们只需要验证表单中的部分字段,其他字段不需要，这时候我们就需要用validateField函数了,注意,这里有几个坑大家别踩了
首先，我们得知道，使用validateField部分校验数组的时候，数组有几位，就会回调几次。当也就是空的时候，表示验证通过，回调返回为“ ”，所以就是，你校验几个规则，就会返回几个结果，如果通过就为“”（空）。
validateField跟validate的区别: 在这两个代码段中已经展示的很清晰了,自己上手跑一跑逻辑就通了
let validateFieldList = [];
this.$refs.loginForm.validateField(
//这里要放数组,数组中写上要校验的字段
["userName", "password", "mobilePhone"],
async (valid) => {
if (!valid) {
//校验通过走这里,每通过一次,会往这个数组里加一个""
validateFieldList.push(valid);
//因为我这里总共校验了三个字段,所有最终三个字段都校验成功之后,数组中会有三个""
if (
validateFieldList.length == 3 &&
validateFieldList.every((item) => item === "")
) {
//这里写校验通过的业务逻辑
}
//校验不通过走这里
return;
}
}补充：validateField方法对部分表单字段进行校验

对于表单中部分字段的校验看如下的代码，当校验不通过时phoneError返回值为校验的提示信息，当通过时phoneError的值为空，所以if语句中用(！phoneError）表示校验通过，完整代码及页面展示图如上。
sendMsg(phoneNum) {
this.$refs.thirdForm.validateField('phone', (phoneError) => {
if(!phoneError){
//当校验通过时，这里面写逻辑代码
}
})
};总结
