如果未定义,js 会覆盖 console.log
您推荐哪种解决方案,第二种更简单(代码更少),但使用它有缺点?
Which solution do you recommend, the second is simpler ( less code ), but there are drawbacks on using it ?
首先:(设置全局调试标志)
// the first line of code
var debug = true;
try {
console.log
} catch(e) {
if(e) {
debug=false;
}
};
// Then later in the code
if(debug) {
console.log(something);
}
第二:覆盖console.log
Second: override console.log
try {
console.log
} catch(e) {
if (e) {
console.log = function() {}
}
};
// And all you need to do in the code is
console.log(something);
推荐答案
不是,而是第二种的变体.丢失 try...catch
并正确检查控制台对象是否存在:
Neither, but a variation of the second. Lose the try...catch
and check for existence of the console object properly:
if (typeof console == "undefined") {
window.console = {
log: function () {}
};
}
console.log("whatever");
