vue3使用svg圖標的多種方式總結(jié)

svg圖片在項目中使用的非常廣泛,下面這篇文章主要給大家介紹了關(guān)于vue3使用svg圖標的多種方式,文中通過實例代碼介紹的非常詳細,需要的朋友可以參考下

方式1使用在線鏈接訪問

在iconfont找到自己的項目的圖標選擇Symbol獲取在線鏈接

2：在vue3項目中找到public的index.html進行script進行引入

打開瀏覽器看：這樣就會自動注入到body下

在項目直接使用

   //控制圖標的大小
   <svg style="width: 10px; height: 10px">
      <use href="#icon-shanchu" rel="external nofollow" ></use>
    </svg>

顯示出了刪除的圖標

封裝的寫法(上面的代碼寫著太重復下面進行封裝)

1:新建一個專門獲取svg圖標的組件

icon.vue (svg/index.vue)

 <template>
  <div>
    <svg :style="style">
      <use :href="names" rel="external nofollow"  rel="external nofollow" ></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>

需要顯示圖標的界面

<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的圖標也自定義了圖標：直接放在一起根據(jù)傳輸?shù)膎ame指定使用哪一個圖標

icon.vue (svg/index.vue)

<template>
  <div>
    <svg :style="style">
      <use :href="names" rel="external nofollow"  rel="external nofollow" ></use>
    </svg>
   // 自定義的圖標
    <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>

假如你是復制的iconfont官網(wǎng)的圖標svg的代碼：

你直接cv到項目也可以直接使用：

<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：

我們還可以把上面的代碼進行改造直接使用在 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"
      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>
    //改造好了直接使用
    <icon :style="{ width: 20, height: 20, color: 'red' }" name="icon"></icon>
  </div>
</template>

<script setup>
import { ref } from "vue";
import icon from "../assets/svg/index.vue";
</script>
<style lang="scss">
 
</style>
