使用element-UI的項(xiàng)目，打包部署以后，偶爾會(huì)出現(xiàn)iconfont顯示亂碼

iconfont顯示為亂碼

但是刷新以后就變成正常了。

經(jīng)過研究以后發(fā)現(xiàn)，圖標(biāo)字體的content經(jīng)過scss編譯以后變成了這樣：

content變成問號(hào)

不過正常情況下圖標(biāo)還是會(huì)顯示的，但是偶爾進(jìn)入頁(yè)面后，所有的iconfont圖標(biāo)會(huì)變成亂碼。

我解決這個(gè)問題的辦法就是直接引入iconfont的css文件，不經(jīng)過scss的編譯，圖標(biāo)的content的就會(huì)是原來的內(nèi)容，一個(gè)轉(zhuǎn)義字符加上數(shù)字字母。像這樣：

content正常

具體做法就是
1.找到項(xiàng)目里自定義element-ui主題的文件element-variables.scss
在這個(gè)文件里本來有一個(gè)引入所有element組件scss文件的一行

@import '~element-ui/packages/theme-chalk/src/index';

把這一行去掉，然后直接element-variables.scss在引入組件的scss文件，當(dāng)然要去掉iconfont的scss
這里是所有組件，你也可以按需引入：

@import '~element-ui/packages/theme-chalk/src/pagination.scss';
@import '~element-ui/packages/theme-chalk/src/dialog.scss';
@import '~element-ui/packages/theme-chalk/src/autocomplete.scss';

@import '~element-ui/packages/theme-chalk/src/popconfirm.scss';
@import '~element-ui/packages/theme-chalk/src/common/transition.scss';

這些就是對(duì)element-variables.scss文件的修改，

2.然后就是重新引入iconfont的css文件，
在element-UI里找到已經(jīng)編譯好的iconfont的文件

.\node_modules\element-ui\lib\theme-chalk

在main.js里引入這個(gè)文件夾下的icon.css就行了。

import 'element-ui/lib/theme-chalk/icon.css'

這樣content里面就是正常內(nèi)容了，字體圖標(biāo)也不會(huì)亂碼了。
