If possible, I'd like to display JavaScript console output in a log window that I developed for my application. There's a lot of solutions for posting messages to the console, but I couldn't find any that let you capture the console output.
I'm not even sure if this is possible. Is console output stored in an object at some level of the DOM?
Thanks in advance for any hints/suggestions.
you can overwrite the console function(s) that you want to use
if(window.console && console.log){
console.log = function(){
var args = arguments;
/* process args to your app */
}
}
console.log before overwriting it.You can overload console.log with a function like the one below, and that function can save the messages in whatever form you'd like, as well as outputting to the console. This particular implementation is a little simplistic though as it only takes one argument, bu can google other examples pretty easily.
var myLog = [];
console.log = function (text) {
console.info(text)
myLog.push(text);
}
console.log("abc")
console.info(myLog);
