Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

vue 表单验证

npm安装

npm install vue-va --save

引入

import validate from 'vue-va'
 Vue.use(validate);

用法

 <input type='text' name='cs' v-va.border.msg="'/[0-9]$/'" data-va-msg="最后一位必须是数字"  />
修改全局默认配置 main.js
validate.option({

  raise:'',   触发表单验证的方式  如keyup,blur,focus,change等事件  默认keyup

  sColor:'',  成功时,border和msg的颜色     默认#67c23a

  eColor:''   失败时,border和msg的颜色     默认#f56c6c

});
全局扩展规则 main.js
validate.extend({   扩展rules
  number(){
   return  /[0-9]/.test(this.value)
  }
})

######自带rules:{email, mobile, tel, cardId, integer}

submit 提交表单触发事件

       this.$validator.validate()
              .then()     //所有v-va绑定的input已经成功通过检测,返回success
              .catch((errMsg)=>{}) //返回errMsg 当前最早data-va-msg触发的错误信息

v-va使用注意

1.使用元素,必须是input 否则抛出错误
2.必须存在name 否则抛出错误
3.如果验证规则不存在或者正则格式错误 则抛出错误

参数规范

#####data-va-raise 更改当前input触发表单验证的方式

#####data-va-msg 自定义错误说明,若不自定义则采用 the field ${name} has error

#####v-va.border 是否开启边框

#####v-va.msg 会在input下方输出data-va-msg的错误说明,若data-va-msg不存在,则使用 the field ${name} has error

#####v-va.disable 关闭空值验证,如不加disable,则默认开启空值验证

#####data-va-validator 自定义验证规则

例:


 <input type='text' name='cs' :data-va-validator="va" v-va.border.msg="'/[0-9]$/'" data-va-msg="长度需大于五位,且最后一位必须是数字"  />

   const validatePassword = function (value) {
     return value.length > 5
   }
   export default {
       data(){
         return {
             va:validatePassword
         }
       }
   }
