旧系统网页性能收集,兼容IE5,低侵入收集网页脚本
开发背景[*]短时间内完成网页性能统计上传,考虑到企业内实际环境,很多网页/系统需要运行在IE 5 兼容模式下,开发一个脚本,在不影响原网页的情况下,收集相应 用户电脑 打开网页的性能指标。
收集要素
[*]进入页面时间,加载Js时间
[*]页面所有元素加载完成时间
[*]因为在原网页将该脚本放到最前面,故两者时间差为用户实际等待页面Ready时间(白屏),实际体验可能与渲染引擎相关(现代浏览器 大大快于IE,故该指标可作参考)
[*]IE 打开页面默认弹窗,会影响结束时间,会以用户点击弹窗作为结束
[*]浏览器信息等可自行拓展
# 使用方法
- 引入代码文件,并给特定`id`, 相应标签属性可追加自定义值,用于辅助统计
- 涉及js 回调,所以需要提前赋值
# 技术特点
- 浏览器兼容(主要是IE 5、低侵入)
- 无三方库,考虑方便快速拓展(function () {
