vue2 自定义svgicon

此次的目的：自定义两个icon

实现方式有好几种，此次用svg     

 这是目标效果：

这是官方社区文档中的原代码：

  1. <template>
  2.   <div class="custom-icons-list">
  3.     <heart-icon :style="{ color: 'hotpink' }" />
  4.     <panda-icon :style="{ fontSize: '32px' }" />
  5.   </div>
  6. </template>
  7. <script>
  8. const HeartSvg = {
  9.   template: `
  10.     <svg width="1em" height="1em" fill="currentColor" viewBox="0 0 1024 1024">

在vue2项目中直接复制粘贴这一块代码肯定是运行不了的，会报警告：

[Vue warn]: You are using the runtime-only build of Vue where the template compiler is not available. Either pre-compile the templates into render functions, or use the compiler-included build.

概括起来就是 “模式不对，编译不了”

具体原因：

        vue2有两种形式的代码 compiler（模板）模式和runtime模式（运行时），Vue2默认为runtime模式（具体原因是因为引入的文件），而官方社区文档中的原代码属于compiler模式的，匹配不上所以就会出现上面的错误信息

解决办法：

解决办法有好几个，我推荐就是直接别写成compiler模式的代码。直接自定义俩组件就行，很简单

demo:

文件结构：

 DiyIcon:

  1. <template>
  2.   <div>
  3.     <PandaIcon :style="{ fontSize: '32px' }"></PandaIcon>
