Answer 1

I have faced the same issue with Android Devices of SonyXperia and HTC. I have developing hybrid application where i am validating Amount text field by reading event.keyCode() of the entered char on keydown event from text field, so that i can allow only numbers and dot(.) char to be entered. I tried but it doesn't worked, returning always 0 in these devices. Later i came with other solution with keyup event and char matching through Regular Expression:

$("#AmountField").keyup(function (e) {

    var regex = /^[0-9\.]$/;
    var str = $(this).val();
    var subStr = str.substr(str.length - 1);
    if(!regex.test(subStr)) {

        if(str.length >0){
            $(this).val(str.substr(0, (str.length - 1)));
        }else{ 
            $(this).val();
        }

    }

});

Hope this can help for the people who facing this issue. Good Luck.
