手里的项目,登录页面在IE下首次进入页面非常的慢,应该不只是登录页面,因为项目我也是半路接手的.开始以为是js的问题,后台把所有的代码都去掉,就一个空白的页面,然后慢慢的试试,最后才发现是一个CSS文件引起的,

在common.css中引用了一个在线的字体路径 'https://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700',罪魁祸首就是这个

/* Include variables for LESS */

/* Import file styles */

@import'https://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700';

@import url(../fonts/font-awesome/css/font-awesome.min.css);

@import url(../plugin/bootstrap/css/bootstrap.min.css);

@import url(../plugin/nprogress/nprogress.css);

body,

html {

    position: relative;

    height: 100%;

    background: #f5f7fa;

    color: #505458;

    font-family: "微软雅黑";

    font-size: 14px

}

那个在线练级打开是这些代码,应该是字体图标,我用不到.

去掉这个就不那么慢了,这是半路接手项目的坑,之前的前端已经离职,然后我来接手
