Question

In my jquery validation I hve below, if multiple validation errors occur, I want all validations to appear in the alert at once, rather than what it is doing at more which is displaying one validation at a time in the alert. How can I display all messages in one alert?

    function validation() {

    var alertValidation = "";
    var _qid = "";
    var _msg = "";

    $("input[data-type='qmark']").each(function(i) {
        var questions = $(this).attr("data-qnum");
        var marks = parseInt($("[class*=q" + i + "_ans_text]").text());
        var txtinput = $(this).val();
        _qid = questions;
        _msg = "You have errors on Question Number: " + _qid + "\n";


        if (txtinput == '') {
            alertValidation += "\n\u2022 You have not entered in a value in all the Indivdiaul Marks textbox\n";
        }


        if (marks < '0') {

            alertValidation += "Your Total Marks Remaining does not equal 0 \n\n\u2022 You Need To Remove " + Math.abs(marks) + " Marks";
        }

        if (marks > '0') {

            alertValidation += "Your Total Marks Remaining does not equal 0 \n\n\u2022 You Have " + marks + " Marks Remaining";
        }

        if (alertValidation != "") {
            return false; //Stop the each loop 
        }

    });


    if (alertValidation != "") {
        alert(_msg + alertValidation);
        return false;
    }

    return true;
}​

Remove this Block of code

if (alertValidation != "") {
    return false; //Stop the each loop 
}

You are already concatenating your error messages , the above line of code breaks your loop when it encounters an error. So removing this should solve your problem..
