How I discovered and solved the problem of project page rendering efficiency (use of IE debugging tool profiler)_html/css_WEB-ITnose
#我是怎么发现并解决项目页面渲染效率问题的（IE调试工具探查器的使用）##背景之前的项目中，有很多的登记页面，一般都有100-200甚至更加多的字段，而且还涉及到字典、日期及其他效果的显示，载入时很慢，而且会有卡死的现象，IE下特别明显##IE调试工具探查器的使用当时找了不少资料，不过最后还是把目光聚焦到IE自带的调试工具了目前我电脑里面的是IE10，当时分析时用的是IE9，里面有一页**探查器**引起了我的注意，经过一轮的折腾，掌握了其分析方法如下：1. 打开要分析的页面，F12进入开发人员工具，并切换到**探查器**页面2. 在点击`开始采样`后进行一系列的操作（由于我的问题是载入页面的效率，自然是刷新页面），结束后再次点击该按钮3. 则会有结果，把视图切换成` 调用树`，则最耗时的函数调用就会一目了然##找到问题用这个方法分析了一下 [示范页面](http://p2227.github.io/demo/applyLayout/elayout.html)，对于结果层层展开（抽丝剥茧）后，终于发现罪魁祸首了：原来是easyui的下拉框、日期框及布局组件最耗时。知道问题所在，就可以针对地解决了。##解决结果于是经过一翻的调整，重新定义了页面和HTML结构，使得效率有了大的提升[调整后的页面](http://p2227.github.io/demo/applyLayout/playout.html)##解决过程小结* [详细方案](http://www.cnblogs.com/p2227/p/3541162.html)
