Code is taking effect when it shouldn't be

Question

I have a function where if the user clicks on a button, it will display a value in the textbox and it will perform a trigger to another function after a \'#btn\' button is click

Answer 1

The problem comes from the fact taht you're setting the data-attribute to false on the $('#mainNumberAnswerTxt') but you're checking against the inputs (this in the click).

One solution would be to do the following test if ($('#mainNumberAnswerTxt').attr('data-ignore') != true)

EDIT

To ensure that the ignore process execute only once (when the grid is reloaded after the modal), you'll have to change what's inside the block after the test:

if ($('#mainNumberAnswerTxt').data('ignore') != true) {
    $('.answertxt', context).val(context.find('.answerBtnsOn').length > 0 ? context.find('.answerBtnsOn').length : 0);
} else {
    /*reset the ignore flag*/
    $('#mainNumberAnswerTxt').data('ignore',false);
}

EDIT2

The main problem is that your reaffecting the $('#mainNumberAnswerTxt').val(numberAnswer) after setting it. Your trying to ignore it through the ignoreattribute.

What i would adivse, would be to remove every occurence to that attribute and to change the following function

function addwindow(questionText,textWeight,numberAnswer,gridValues,reply,btn) {
    var answers = $.map(btn.split(''),function(chr){ return "#answer"+chr; }).join(', ');
    if($(plusbutton_clicked).attr('id')=='mainPlusbutton') {
        var myNumbers = {};
        myNumbers["A-C"] = "3";
        myNumbers["A-D"] = "4";
        myNumbers["A-E"] = "5";
        myNumbers["A-F"] = "6";
        myNumbers["A-G"] = "7";
        gridValues = myNumbers[gridValues];
        $('#mainNumberAnswerTxt').show();
        $('#mainNumberAnswerTxt').val(numberAnswer).data('ignore',true);
        $('#mainGridTxt').val(gridValues).parent().append($('.optionTypeTbl'));
        $('#btn'+gridValues).trigger('click');
        $('.answers.answerBtnsOn').removeClass('answerBtnsOn').addClass('answerBtnsOff');
        $(answers).addClass("answerBtnsOn").siblings().addClass('answerBtnsOff');
    }
    $.modal.close();
    return false;
} 

to :

function addwindow(questionText,textWeight,numberAnswer,gridValues,reply,btn) {
    var answers = $.map(btn.split(''),function(chr){ return "#answer"+chr; }).join(', ');
    if($(plusbutton_clicked).attr('id')=='mainPlusbutton') {
        var myNumbers = {};
        myNumbers["A-C"] = "3";
        myNumbers["A-D"] = "4";
        myNumbers["A-E"] = "5";
        myNumbers["A-F"] = "6";
        myNumbers["A-G"] = "7";
        gridValues = myNumbers[gridValues];
        $('#mainNumberAnswerTxt').show();
        $('#mainGridTxt').val(gridValues).parent().append($('.optionTypeTbl'));
        $('#btn'+gridValues).trigger('click');
        /* moved the following line below the click simulation, 
           hence its value will be changed regardless of what happened during the click simulation*/
        $('#mainNumberAnswerTxt').val(numberAnswer);
        $('.answers.answerBtnsOn').removeClass('answerBtnsOn').addClass('answerBtnsOff');
        $(answers).addClass("answerBtnsOn").siblings().addClass('answerBtnsOff');
    }
    $.modal.close();
    return false;
} 

In order to modify the value after the visual changes took place.
