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); } }
