vue3使用svg图标多种方式

方式1使用在线链接访问
在iconfont找到自己的项目的图标选择Symbol获取在线链接

2：在vue3项目中找到public的index.html进行script进行引入

打开浏览器看：这样就会自动注入到body下

在项目直接使用

//控制图标的大小<svg style="width: 10px; height: 10px"><use href="#icon-shanchu"></use></svg>

显示出了删除的图标

封装的写法(上面的代码写着太重复下面进行封装)
1:新建一个专门获取svg图标的组件

icon.vue (svg/index.vue)

<template><div><svg :style="style"><use :href="names"></use></svg></div></template><script setup>
import { defineProps, withDefaults } from "vue";const props =defineProps({
  name:{
    type: String,default:"",},
  style:{
    type: Object,default:()=>{return{
        width:10,
        height:10,
        color:"",};},},});const names = `#${props.name}`;</script><style lang="scss" scoped></style>

需要显示图标的界面

<template><div class="home"><icon   :style="{ width: 10, height: 10, color: 'red' }"  name="icon-shanchu"></icon><icon   :style="{ width: 10, height: 10, color: 'red' }"  name="icon-shanchu"></icon></div></template><script setup>
import { ref } from "vue";
import icon from "../assets/svg/index.vue";</script><style lang="scss"></style>

假如你既引用了iconfont的图标也自定义了图标：直接放在一起根据传输的name指定使用哪一个图标
icon.vue (svg/index.vue)

<template><div><svg :style="style"><use :href="names"></use></svg>// 自定义的图标<svg width="0" height="0"><defs><symbol id="more" viewBox="0 0 100 100"><circle
            r="5"
            cx="20"
            cy="25"
            fill="transparent"
            stroke="green"></circle><circle r="5" cx="20" cy="50" fill="currentColor"></circle><circle r="5" cx="20" cy="75" fill="currentColor"></circle><line
            x1="40"
            y1="25"
            x2="90"
            y2="25"
            stroke-width="8"
            stroke="currentColor"></line><line
            x1="40"
            y1="50"
            x2="90"
            y2="50"
            stroke-width="8"
            stroke="currentColor"></line><line
            x1="40"
            y1="75"
            x2="90"
            y2="75"
            stroke-width="8"
            stroke="currentColor"></line></symbol></defs></svg></div></template><script setup>
import { defineProps, withDefaults } from "vue";const props =defineProps({
  name:{
    type: String,default:"",},
  style:{
    type: Object,default:()=>{return{
        width:10,
        height:10,
        color:"",};},},});const names = `#${props.name}`;</script><style lang="scss" scoped></style>

使用：

<template><div class="home"><icon  :style="{ width: 10, height: 10, color: 'red' }"   name="icon-shanchu"></icon><icon  :style="{ width: 10, height: 10, color: 'red' }"  name="icon-shanchu1"></icon><icon :style="{ width: 20, height: 20, color: 'red' }" name="more"></icon></div></template><script setup>
import { ref } from "vue";
import icon from "../assets/svg/index.vue";</script><style lang="scss"></style>

假如你是复制的iconfont官网的图标svg的代码：

你直接cv到项目也可以直接使用：

<svg
      t="1673881805558"
      class="icon"
      viewBox="0 0 1024 1024"
      version="1.1"
      xmlns="http://www.w3.org/2000/svg"
      p-id="1076"
      width="200"
      height="200"><path
        d="M658.276045 767.993958 658.276045 274.295l329.126 0L987.402045 219.44 658.276 219.44l0-18.281c0-80.787046-65.492992-146.284032-146.276045-146.284032-80.790016 0-146.276045 65.496986-146.276045 146.284032l0 18.281L36.597 219.44l0 54.855 109.695 0 0 694.83L877.7 969.125l0-548.55-54.855 0L822.845 914.27l-621.69 0L201.155 274.295l164.569 0 0 493.699 54.848 0L420.572 274.295l182.85 0 0 493.699L658.276 767.994zM420.571034 219.440026l0-18.281c0-50.492006 40.932966-91.420979 91.428966-91.420979 50.489037 0 91.420979 40.928973 91.420979 91.420979l0 18.281L420.571 219.440026z"
        p-id="1077"></path></svg>

效果如下：

我们还可以把上面的代码进行改造直接使用在 icon.vue (svg/index.vue)改造

<template><div class="home"><icon
      :style="{ width: 10, height: 10, color: 'red' }"
      name="icon-shanchu"></icon><icon
      :style="{ width: 10, height: 10, color: 'red' }"
      name="icon-shanchu1"></icon><icon :style="{ width: 20, height: 20, color: 'red' }" name="more"></icon><svg
      t="1673881805558"
