How can I catch console.log messages?
你可以给真正的 console.log 方法打猴子补丁,然后对输入做任何你喜欢的事情:
You can monkey-patch the real console.log method and do whatever you like with the input:
var realConsoleLog = console.log; console.log = function () { var message = [].join.call(arguments, " "); // Display the message somewhere... (jQuery example) $(".output").text(message); realConsoleLog.apply(console, arguments); };
这是一个工作示例.它记录对 .output 元素中的 console.log 的调用,以及像往常一样在控制台中的调用.
Here's a working example. It logs calls to console.log in the .output element, as well as in the console like usual.
