我正在研究Twitter源代码,我遇到了以下片段：
window.setTimeout=window.setTimeout;window.setInterval=window.setInterval;
编辑：
要查看代码,请转到任何Twitter用户页面,打开页面源,您将在第二个javascript块中看到该片段.@H_301_5@
解决方法
这是一种以跨浏览器方式全局替换setTimeout和setInterval函数的技术.
window.setTimeout,when used as an lvalue (on the left side of the
assignment),does not walk the prototype chain,but on the right side,
it does. So this will always pull a property out of the prototype
chain and put it right on the object.@H_301_5@
