vue开发：如何避免用户多次点击

在产品页面上，有一些按钮经常会被用户重复点击，尤其是网络慢的时候，经常会出现，所以开发的时候如何避免用户多次点击呢？

方法

在点击事件的方法最前面加上定义变量hasRemind来控制是否执行点击事件里的相应操作

当用户第一次点击的时候，hasRemind = false，此时，进入到第二个if语句，讲hasRemind的值改变为true，并且在3秒后再将hasRemind的值改为false，这是情况下，用户可以正常进入到点击事件里的所有流程

当用户第二次点击的时候，hasRemind=true，此时直接跳出点击事件，等待hasRemind的值为false的时候才能继续进行该点击方法里的系列流程 

//默认可以触发登录的点击事件
hasRemind:false,

//防止连续多次点击
let vm = this;
if(this.hasRemind === true)  return;
if(this.hasRemind === false){
    this.hasRemind = true;
    setTimeout(function(){
       vm.hasRemind = false;
    },3000)
}

这里就是将上述代码段放在了登录的点击事件里，以防止用户多次点此，出现很多条提示信息的情况。

 // "个人登录点击事件"
            registerBtn() {
                //防止连续多次点击
                let vm = this;
                if(this.hasRemind === true)  return;
                if(this.hasRemind === false){
                    this.hasRemind = true;
                    setTimeout(function(){
                        vm.hasRemind = false;
                    },3000)
                }
                var qs = Qs;
                if (this.logintype == 1) {
                    //账号密码登录
                    if (this.username == "") {
                        this.$message({
                            message: '请输入账号',
                            type: 'warning'
                        });
                        return false;
                    }
                    else if (this.password == "") {
                        this.$message({
                            message: '请输入密码',
                            type: 'warning'
                        });
                        return false;
                    } else {
                        request_POST('/login', qs.stringify({
                            identity: this.username,
                            desStr: this.password,
