方案一:
var console = console || { log : function() { return; } };//兼容IE,当IE不支持console.log时,自定义一个包含log方法的对象给他
方案二:HTML5 Boilerplate 也提供了一个处理所有的 Console call 的 fallback
// Avoid `console` errors in browsers that lack a console.
(function() {
var method;
var noop = function () {};
var methods = [
'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
'timeStamp', 'trace', 'warn'
];
var length = methods.length;
var console = (window.console = window.console || {});
while (length--) {
method = methods[length];
// Only stub undefined methods.
if (!console[method]) { //对于不支持的方法用noop函数代替
console[method] = noop;
}
}
}());
// Place any jQuery/helper plugins in here.
方案三:自定义封装个方法调用
function log(msg){
if (window["console"]){
console.log(msg);
}
}
