javascript - Console.log in IE8 - Stack Overflow

文章数量:1356549

I have below piece of code, which, when tested, does not work in IE8. I have it running on IE11 and Chrome and it runs perfectly. I have debugged the code in IE8 which points at "console.log as a problem area. The most interesting thing is that when I start debugging JS in IE8 - it kicks it and this piece of code start working. Then again, on leaving debugging, closing and re-opening file - same story until you get into debugging))).

jQuery(function () {
    $('.Response input[type=radio]').change(function () {
        console.log(this.value)
        if (this.value == 'Y' || this.value == 'NA' || this.value == 'NS') {
            $(this).closest('.ui-accordion-content').prev().css("background", "#AADDB2"); 
        } else if (this.value == 'N') {
            $(this).closest('.ui-accordion-content').prev().css("background", "#FFC5C5"); 
        }
    });
});

Any ideas? Would appreciate yr help. PS. Unfortunately, user kind of "must" use IE8 and upgrading is not an option(((. Thank you in advance)))

you can prevent ie8 errors on console.log with

if (!window.console){ console = {log: function() {}} };

You can add some safety code to define console if it doesn't exist:

if (typeof console === "undefined" || typeof console.log === "undefined") {
    console.log = function(log_message) {
        alert(log_message);
    };
}
