推荐答案
我通常做一个这样的包装函数:
i usually make a wrapper function like so:
function log(obj) {
if (window.console && console.log) console.log(obj);
}
或者你可以在你的脚本文件/元素的开头做这样的事情:
or you could do something like this at the beginning of your script file/element:
if (!window.console) {
window.console = {
log: function(obj){ /* define own logging function here, or leave empty */ }
};
}
