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 🙏

vue-layer-af

为了满足其它场景需求,本组件在 vue-layer 的基础上进行修改

更新功能

#####1、iframe弹窗关闭时允许在子组件中重载beforeLayerClose(layerid)方法,返回true则继续关闭流程,返回false则由组件自己控制 #####2、iframe增加slots插槽传值,允许组件定义插槽

install

npm install vue-layer-af
  // "eslint:recommended"

Quick Start

在程序入口添加

import Vue from 'vue';
import layer from 'vue-layer'
import 'vue-layer/lib/vue-layer.css';

Vue.prototype.$layer = layer(Vue);

全局参数重置

import Vue from 'vue';
import layer from 'vue-layer'
Vue.prototype.$layer = layer({
    msgtime: 3,//目前只有一项,即msg方法的默认消失时间,单位:秒
});

调用

this.$layer.alert("找不到对象!");

Attribut

{
  type: 0, //0(信息框,默认)1(页面层)2(iframe层)3(加载层)4(tips层)
  title: '信息',
  content: '',
  area: 'auto',
  offset: 'auto',
  icon: -1,
  btn: '确定',
  time: 0,
  shade: true,//是否显示遮罩
  yes: '',
  cancel: '',
  tips: [0,{}],//支持上右下左四个方向,通过1-4进行方向设定,可以设定tips: [1, '#c00']
  tipsMore: false,//是否允许多个tips
  shadeClose: true,//点击遮罩是否关闭
  maxmin: true,//开启最大化最小化
  scrollbar: true, //是否允许浏览器出现滚动条:默认是允许
  resize: false //是否允许拉伸,默认是不允许
}

Method

 layer.alert(content, [options, yes]);
 // options和yes可以省略, 如果您不愿意写options,则可以直接写确定按钮的函数,即yes
 // content 可以为html
 //yes如果是个function,这会自动添加参数layerid,
 (layerid)=>{
   this.$layer.close(layerid);
 }
 layer.confirm(content, [options, yes, cancel]);
  // options,yes和cancel可以省略, 如果您不愿意写options,则可以直接写确定按钮的函数,即yes,或者覆盖默认的cancel方法。PS:yes和cancel方法不能互换
  //content 可以为html
   //yes,cancel如果是个function,这会自动添加参数layerid,
 (layerid)=>{
   this.$layer.close(layerid);
 }
 layer.loadding(option);
  // options ={time:3},3秒自动关闭
  //options = {content:'请等待'} //可传入文字
 layer.msg(content, [options, end]);
 // options和end可以省略, 如果您不愿意写options,则可以直接写时间到期的回调即可,即end方法
 // 默认msg的关闭时间为1.5秒
 // content 可以为html
 layer.prompt(options, yes);
 //特殊参数: value 要回显的值
 //formType: 1text,2password,3textarea
layer.tips(content, follow, options);
//content 可以为html
//follow对css选择器,用来定位目标
layer.iframe({
  content: {
    content: componentName, //传递的组件对象
    parent: this,//当前的vue对象
    data:{},//props
    slots:{ //插槽
      default: function (slotProps) {
        return h('div',null,'default slot' + slotProps.tname)
      },
      test: function () {
        return ['test named slot']
      }
    }
  },
  area:['800px','600px'],
  title: 'title',
  beforeLayerClose (layerid) { 
    //弹窗关闭前拦截事件,返回false,则弹窗不关闭
    return true;
  },
  cancel:()=>{//关闭事件
     alert('关闭iframe');
  }
});
// data参数可认为是componentName的props,同时 该方法会自动添加一个key为layerid的值, 该值为创建层的id, 可以直接用来关闭该层
// options参数直接写到json里即可,比如title
layer.close(id);
layer.closeAll(type);
//弹窗最大化
layer.full(layerid);
//弹窗最小化
layer.min(layerid);
//还原弹窗
layer.restore(layerid);

关于this.$layer.iframe

其实使用iframe层,除了操作方便外,主要的目的是隔离代码, 降低代码复杂度。而在vue中,组件就是功能块的基本单位了,所以vue-layer中并不存在iframe的DOM元素,这里用的都是组件。 这里的content有三个参数:

content:

此参数为组件对象, 比如

 import editFrom from './edir-form.vue';

此处content就为editFrom即可。

parent:

此参数其实就是当前调用layer的vue对象, 即this即可。在editForm中可以直接使用, this.$parent来获取调用layer的vue对象,然后父子传值神马的,就很easy,当然也可以直接使用vuex,就不用this.$parent了,另外自动注入了原始数据的浅拷贝lydata,也可以直接赋值这个数据来同步父对象的数据

data:

此参数可认为是editForm的props,传递到iframe后是这个数据的深拷贝,改变数据不会影响来源数据,然后你懂得。

  • 该方法会自动添加一个key为layerid的值, 该值为创建层的id, 可以直接使用
  • 该方法会自动添加一个key为lydata的值, 该值为data的浅拷贝, 当iframe要更改父窗口传递的数据的时候,可以直接使用lydata来修改,对于表单使用非常方便

结果即为:

methods:{
   eidt() {
	  this.$layer.iframe({
		content: {
		  content: editForm, //传递的组件对象
		  parent: this,//当前的vue对象
		  data:{
        info:{a:1}
      }//props
		},
		area:['800px','600px'],
		title:"editForm"
	  });
  }
}

iframe组件中

export default {
  data() {
    return {
      form: {
      }
    };
  },
  props: {
    info: {
      type: Object,
      default: () => {
        return {};
      }
    },
    layerid: {
      type: String,
      default: ""
    },
    lydata: {
      type: Object,
      default: () => {
        return {};
      }
    },
    lyoption: {
      type: Object,
      default: () => {
        return {};
      }
    }
  },
  methods: {
    onSubmit() {
      this.$layer.msg("提交成功", () => {
        this.lydata.info.name = this.form.name;
        this.$layer.close(this.layerid);
      });
    },
    cancel() {
      this.$layer.close(this.layerid);
    }
  },
  mounted() {
    this.form = this.info
  }
};
