ie8不支持console.log()的解决方法

1、在ie8(其他版本没测）下用console.log('abc') 在控制台调试会报错，如下图：

2.解决方法

window.console = window.console || (function () {
    var c ={}; 
　　 c.log = c.warn = c.debug = c.info = c.error = c.time = c.dir = c.profile= c.clear = c.exception = c.trace = c.assert = function(){};
    return c;
})();
