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 🙏

基于 element-ui 2.x 扩展下拉带树的组件 下拉树状菜单

Demo

在线API
在线测试

Image text

如果本地启动API需要全局安装:npm install -g @vuese/cli

需在main.js注册组件:

import ElTreeSelect from 'el-tree-select';
vue.use(ElTreeSelect);
内部直接使用 :  <el-tree-select v-model="id"/>

API:

特殊点(屏蔽 el-select、el-tree 的几个参数):

el-select 取消参数:
multiple                       改为内置,通过v-model类型判断是否多选
:filterable="false"            搜索从弹出框里面执行
:filterable="false"            搜索从弹出框里面执行
el-tree 取消参数:
:show-checkbox="selectParams.multiple"  使用下拉框参数multiple 判断是否对树进行多项 取消对el-tree的人为传参show-checkbox
:node-key="propsValue"  自动获取treeParams.props.value
:draggable="false"      屏蔽拖动

支持的参数:

el-select 参数:

selectParams  :     支持el-select 相关参数

#### styles参数:
styles 对el-select设置style,类型:Object

#### selectClass参数:
selectClass  对el-select设置class,类型:String

el-tree 参数:

treeParams  :     支持el-tree 相关参数
增加:'clickParent'
treeParams.clickParent 类型:Boolean 默认:false
在selectParams.multiple=false单选情况下点击节点,判断是否关闭弹出框
clickParent: true 允许点击父级关闭弹出框 false 只能点击子级关闭弹出框

popover 参数:

popperClass  对应:popper-class,类型:String

搜索框参数:

treeParams.filterable   Boolean 考虑是显示在弹出框内的,因此放到treeParams参数内

事件:

select-clear
select-clear 下拉框清空事件   this.$emit('select-clear');
removeTag
removeTag 移除单个标签,返回所有勾选的ids,以及当前移除的tag(可能为中文)标签   this.$emit('removeTag',ids,tag);
node-click
树点击,和el-tree参数一致: this.$emit('node-click', data, node, vm);
check
勾选触发,和el-tree参数一致: this.$emit('check',data, node, vm);
treeDataUpdateFun
treeDataUpdateFun 树更新数据

this.post(url,postobj,response=>{
    this.$refs.treeSelect.treeDataUpdateFun(response.data);
});
searchFun 参数: keywords
searchFun(value){
    // 如果是本地过滤:
    this.$refs.treeSelect.$refs.tree.filter(value);
    // 可以直接访问方法,也可以拿到 $refs.tree
    this.$refs.treeSelect.filterFun(val);
    // 如果是请求后台:
    this.post(url,postobj:{
        keywords:value
    },response=>{
        this.$refs.treeSelect.treeDataUpdateFun(response.data);
    });
}
filterFun 参数: 本地过滤树
this.$refs.treeSelect.filterFun(val);
