  20. //======说明=======
  21. /*
  22. 如果觉得卡顿
  23. 请修改配置参数项
  24.  
  25. config.isAnimate:GM_getValue("isAnimate",false) 		关闭CSS3动画(默认开启)
  26. config.mixRequireMod:false 								关闭混合请求(默认开启)
  27.  
  28.  
  29. 不懂代码就不用管
  30.  
  31. 混合请求说明：存在两种请求方式
  32. 1，把所有跳转链接请求个遍，类似于图片的延迟加载。页面滚动到哪里请求到哪里。
  33. 2，把当前页面的href的参数&fn=baiduhome_pg修改成&fn=baidulocal，得到一个全新的页面。也没的链接没有跳转，然后替换到当前页面的链接。
  34.  
  35. 如果关闭混合请求，那么执行第一种，第二种不执行。
  36.  
  37. 为什么关闭第二种方式：(不推荐关闭，理论上是好的)
  38. 存在缺陷，替换的链接不全。
  39. 请求的文件比第一种大，可能造成性能的问题。(chrome下和firefox下测试均没问题，当然，其他脚本\扩展也是用这种方法)。
  40. 请求方式的统一性。
