  • v-dialog-drag: Dialog 组件拖拽任意位置
  • v-dialog-drag-width: Dialog 组件拖拽宽度
  • v-dialog-corner: Dialog 组件右下角拖拽宽度高度
  • v-clipboard: 剪切板指令,类似 复制Ctrl + C等复制文本至剪切板

提供原型方法:

  • $clipboard(): 剪切板方法,类似 复制Ctrl + C等复制文本至剪切板

How to use

yarn add vue-element-utils
npm install vue-element-utils

入口文件引入:

import elementUtils from 'vue-element-utils'

Vue.use(elementUtils);

<template>
    <el-select v-model="value" placeholder="请选择" v-el-select-scroll="selectScroll">
        <el-option
            v-for="item in options"
            :key="item.value"
            :label="item.label"
            :value="item.value"
        >
        </el-option>
    </el-select>
</template>

<script>
function createOptions(len, start = 0) {
    return Array(len)
        .fill(0)
        .map((_, index) => ({
            value: `选项${start + index}`,
            label: `我是${start + index}`
        }));
}

export default {
    data() {
        return {
            options: createOptions(10),
            value: '',
            pageIndex: 0,
        };
    },
    mounted() {
        this.options = createOptions(10);
    },
    methods: {
        selectScroll() {
            console.log('selectScroll');
            // Select 滚动到底部 执行该方法
            // 这里可以做一些懒加载之类的事情,eg:
            this.pageIndex++;
            this.options.push(...createOptions(10, 10 * this.pageIndex));
        },
    }
