accessing errors thrown in console using javascript/jquery

Question

is there a way in which we can get the list of errors in the console using pure javascript or jquery or any other client side script?

console.error("params")

just creates error, but I am not able to access the list of errors in console with it

There's no build in function in javascript to get a list of all errors but you may use window.onerror to append the error message to an array each time you get one.

var myErrors = [];
startTrackingErrors = true;

window.onerror = function (errorMessage, url, lineNumber) {
    if (!startTrackingErrors) { return false; }
    myErrors.push({
      errorMessage : errorMessage,
      url : url,
      lineNumber : lineNumber
    });
    return true;
};

Here's a working demo (with error :P)
