通过在线转换,我们将下载下来的 font 文件放入项目中,并新建一个 CSS 文件来声明所有图标。
@font-face { font-family: 'icomoon'; src: url('../assets/fonts/icomoon.eot?vpkwno'); src: url('../assets/fonts/icomoon.eot?vpkwno#iefix') format('embedded-opentype'), url('../assets/fonts/icomoon.ttf?vpkwno') format('truetype'), url('../assets/fonts/icomoon.woff?vpkwno') format('woff'), url('../assets/fonts/icomoon.svg?vpkwno#icomoon') format('svg'); font-weight: normal; font-style: normal; } [class^="icon-"], [class*=" icon-"] { /* use !important to prevent issues with browser extensions that change fonts */ font-family: 'icomoon' !important; speak: none; font-style: normal; font-weight: normal; font-variant: normal; text-transform: none; line-height: 1; vertical-align: sub; /* Better Font Rendering =========== */ -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } .icon-edit:before { content: "\e900"; }
之后就能通过 CSS 类名的方式来引用图标了。
<span class="icon-edit"></span>
为了使主题生效,我们也需要把图标的 CSS 写入 theme.css 文件中
.icon_edit:before { background-image: linear-gradient(-135deg, #879FFF 0%, #B7A3FF 100%); }
图片切换
项目中还存在很多占位图或者其他图片会随着主题的变化而变化。通过引入所有图片,并用文件名来区分不同主题所对应的图片。在点击切换主题时,切换到主题所对应的文件,就能实现图片切换了。为此,我写了一个 mixin,并在组件中引入 mixin。
<img :src="userImg || placeholderWoman">
placeholderMixin
let callback const placeholderMixin = { data () { return { placeholderWoman: '', placeHolderNoReply: '', placeHolderNothing: '' } }, created () { let themeId = localStorage.getItem('themeId') let theme = themeId2Name(themeId) this.setThemeValue(theme) callback = (theme) => { this.setThemeValue(theme) } bus.$on('changeTheme', callback) }, destroyed () { bus.$off('changeTheme', callback) }, methods: { setThemeValue (theme) { this.placeholderWoman = require(`@/assets/placeholder_woman_${theme}.svg`) this.placeHolderNoReply = require(`@/assets/icon_noreply_${theme}.svg`) this.placeHolderNothing = require(`@/assets/icon_nothing_${theme}.svg`) } } }
在点击切换主题时,会发射一个 changeTheme 事件,各组件接收到 changeTheme 事件,就会为图片重新赋值,也就达到了切换图片的效果。
let theme = themeId2Name(this.themeId) bus.$emit('changeTheme', theme)
