vue简单封装button和modal

封装button

<template>
  <button :class="'button button-'+type" @click="handleClick"><slot></slot></button>
</template>

<script lang="ts">
import { defineComponent, PropType } from "vue";

export default defineComponent({
  props: {
    type: String as PropType<"primary" | "default">,
  },
  emits: ["click"],
  methods: {
    handleClick: function () {
      this.$emit("click");
    },
  }
});
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.button {
  background: #fff;
  color: #333;
  border: 1px solid #d9d9d9;
  cursor: pointer;
  outline: none;
  font-size: 14px;
  height: 32px;
  display: inline-flex;
  align-items: center;
  box-sizing: border-box;
  padding: 4px 15px;
  transition: all 0.3s ease-in-out;
}
.button-default:hover {
  color: #40a9ff;
  border-color: #40a9ff;
}
.button-primary {
  background: #1890ff;
  color: #fff;
  border-color: #1890ff;
}
.button-primary:hover {
  background: #40a9ff;
  border-color: #40a9ff;
}
</style>

使用：

 <Button>默认按钮</Button>
 <Button type="primary">主按钮</Button>

modal

封装

<template>
  <div :class="visible ? 'modal modal-visible' : 'modal'">
    <div class="modal-mask" @click="handleClose" />
    <div class="modal-box">
      <div class="modal-head">
        <span>{{title}}</span>
        <svg

          focusable="false"
          data-icon="close"
          width="1em"
          height="1em"
          fill="currentColor"
          aria-hidden="true"
