Text reversed on input

There is a email field where in if we access the site using chrome/IE/Firefox browser it works as expected, But if I access it using IPhone Safari browser the email field reverse the text I entered.
Example image here-
The code for the field Email is
<input
id="emal"
required
type="text"
maxlength="40"
onclick="this.focus();"
onfocus="if(this.value == this.dflt) { this.value='' }; this.onchange();"
onblur="if(this.value.length < 1) { this.value = this.dflt };"
onchange="this.ffoc = true; validate_email();"
onpaste="this.onchange();" oninput="this.onchange();"
onkeypress="this.onchange();">
Validation part of code -
function validate_email() {
if (document.loaded) {
$form[0].$emal.value = "";
$form[0].$emal.valid = null;
updateField($form[1].$emal, $form[1].$emal.value.replace(/\s/ig, ""));
if (isValidEmail($form[1].$emal.value) && $form[1].$emal.value != $form[
1].$emal.dflt) {
$form[0].$emal.value = $form[1].$emal.value;
$form[0].$emal.valid = true;
$form[1].$emal.setAttribute("valid", "true");
} else {
$form[1].$emal.setAttribute("valid", ($form[1].$emal.clik) ? ($form[
1].$emal.required) ? "false" : "warn" : "");
$form[0].$emal.valid = ($form[1].$emal.clik && !$form[1].$emal
.required) ? true : null;
}
$form[1].$emal.$wbox.style.display = ((/false|warn/i).test($form[1]
.$emal.getAttribute("valid"))) ? "block" : "none";
refresh();
}
}
function isValidEmail(str) {
var val = false;
if (str != null) {
var ddStr =
"aero%asia%biz%cat%com%coop%edu%gov%info%int%jobs%mil%mobi%museum%name%net%org%pro%tel%travel%ac%ad%ae%af%ag%cf%cg%ai%al%am%an%ao%aq%ar%as%at%au%aw%ax%az%ba%bb%bd%be%bf%bg%bh%bi%bj%bm%bn%bo%br%bs%bt%bv%bw%by%bz%ca%cc%cd%ch%ci%ck%cl%cm%cn%co%cr%cs%cu%cv%cx%cy%cz%dd%de%dj%dk%dm%do%dz%ec%ee%eg%eh%er%es%et%eu%fi%fj%fk%fm%fo%fr%ga%gb%gd%ge%gf%gg%gh%gi%gl%gm%gn%gp%gq%gr%gs%gt%gu%gw%gy%hk%hm%hn%hr%ht%hu%id%ie%il%im%in%io%iq%ir%is%it%je%jm%jo%jp%ke%kg%kh%ki%km%kn%kp%kr%kw%ky%kz%la%lb%lc%li%lk%lr%ls%lt%lu%lv%ly%ma%mc%md%me%mg%mh%mk%ml%mm%mn%mo%mp%mq%mr%ms%mt%mu%mv%mw%mx%my%mz%na%nc%ne%nf%ng%ni%nl%no%np%nr%nu%nz%om%pa%pe%pf%pg%ph%pk%pl%pm%pn%pr%ps%pt%pw%py%qa%re%ro%rs%ru%tw%tz%ua%ug%uk%us%uy%uz%va%vc%ve%vg%vi%vn%vu%wf%ws%ye%yt%yu%za%zm%zw",
ckStr = (ddStr).split("%");
if (str.length > 5 && (
/^\w+([\.\-\'\+]?\w+)*#\w+([\.\-]?\w+)*(\.\w+)+$/i).test(str)) {
for (var i = 0; i < ckStr.length; i++) {
if (str.substring(str.lastIndexOf(".") + 1) == ckStr[i]) {
val = true;
break;
}
}
}
}
return val
}
I really appreciate helping me sorting this or providing any references.

Divide two Inputs and multiply 100

I have the two functions match and and total working properly. I want the function total project match to divide the first function over the second function multiply times 100. the last function isn't working!
Here is my code so far :
matchContribution.subscribe(function (newValue) {
if (newValue != undefined && newValue != '') {
matchContribution(formatInt(newValue));
var dataValue = Number(matchContribution().replace(/\,/g, ''));
if (dataValue > 999999999999.99 || dataValue < 0) {
matchContribution('');
}
if (loading == false) {
sendCommand('SAVE');
}
}
});
var totalProjectCost = ko.computed(function () {
var total = 0;
var hasUserInput = false;
if (grantRequest() != '' && grantRequest() != undefined) {
hasUserInput = true;
total = total + Number(String(grantRequest()).replace(/\,/g, ''));
}
if (matchContribution() != '' && matchContribution() != undefined) {
hasUserInput = true;
total = total + Number(String(matchContribution()).replace(/\,/g, ''));
}
if (total == 0) {
if (!hasUserInput)
return '';
else
return formatInt('0');
}
else {
if (loading == false) {
sendCommand('SAVE');
}
return formatInt(total);
}
});
var totalProjectMatch = matchContribution()/totalProjectCost();
if(totalProjectMatch>=0)
totalProjectMatch = Math.floor(totalProjectMatch);
else
totalProjectMatch = Math.ceil(totalProjectMatch);

var totalProjectMatch = ko.computed(function () {
var total = 0;
var hasUserInput = false;
if ((grantRequest() != '' && grantRequest() != undefined) && (matchContribution() != '' && matchContribution() != undefined) && (totalProjectCost() != '' && totalProjectCost() != undefined)) {
hasUserInput = true;
total = Number(String(matchContribution()).replace(/\,/g, '')) / Number(String(totalProjectCost()).replace(/\,/g, ''));
total = total * 100;
}
if (total == 0) {
if (!hasUserInput)
return '';
else
return formatInt('0');
}
else {
if (loading == false) {
sendCommand('SAVE');
}
return formatNumber(total);
}
});
I solved the problem! Thanks a lot! Hope that helps other people.

KnockoutJs binding for input tag to format number with comma

Is there available binding to format an input value from 123456789 to 123,456,789. The binding should work on every keypress and validate the value if it is a valid number. I found this solution but it is not formatting on keypress.

I ended up creating custom binding. It only works on IE10 and above for the usage of event input.
Here's the code. See fiddle here.
String.prototype.countOccurence = function(char){
return (this).split(char).length - 1;
}
$.fn.selectRange = function(start, end){
if(end === undefined)
end = start;
return this.each(function() {
if("selectionStart" in this){
this.selectionStart = start;
this.selectionEnd = end;
} else if(this.setSelectionRange)
this.setSelectionRange(start, end);
else if(this.createTextRange){
var range = this.createTextRange();
range.collapse(true);
range.moveEnd("character", end);
range.moveStart("character", start);
range.select();
}
});
};

Allow to enter only 2 decimal points number

I have a condition to allow user to input only 2 decimal points number and restrict the alphabets and other characters. I used the following function:
function isNumberKeyOnlyWithDecimalFormat(event,value,id){
var val = value;
if (event.shiftKey === true) {
event.preventDefault();
}
if ((event.keyCode >= 48 && event.keyCode <= 57) ||
(event.keyCode >= 96 && event.keyCode <= 105) ||
event.keyCode == 8 ||
event.keyCode == 9 ||
event.keyCode == 37 ||
event.keyCode == 39 ||
event.keyCode == 46 ||
event.keyCode == 190) {
} else {
event.preventDefault();
}
if(val.indexOf('.') !== -1 && event.keyCode == 190){
event.preventDefault();
}
if ((pointPos = $('#'+id).val().indexOf('.')) >= 0){
$('#'+id).attr("maxLength", pointPos+3);
}
else
$('#'+id).removeAttr("maxLength");
}
It is working fine while first time adding. But it restricts the if i want to edit the digits if it has already 2 decimal place. Can anyone help with this?

Try this. It will check the value each time the focus is gone from the input field, but you can use any event you like. It will parse the value as a float, and then round it to 2 decimal points.
Here is the fiddle: http://jsfiddle.net/sAp9D/
HTML:
<input type="text" id="the_id" />
JavaScript:
var input_field = document.getElementById('the_id');
input_field.addEventListener('change', function() {
var v = parseFloat(this.value);
if (isNaN(v)) {
this.value = '';
} else {
this.value = v.toFixed(2);
}
});

Your question is very hard to understand but if you want to check that a string has only 2 decimals then you can just do this
if( value.match(/\./g).length === 2 ) {
// Number has 2 decimals eg. 1.2.3
} else {
// Number is incorrect eg. 1.2.3.4
}
or if you want 1.2 then
if( value.match(/\./g).length === 1 ) {
// Code....
}

I use the following
// This function will only allow digits
function numericFormat( fld , e , extraStrCheck )
{
var sep = 0;
var key = '';
var i = j = 0;
var len = len2 = 0;
var strCheck = '0123456789';
if ( extraStrCheck )
strCheck += extraStrCheck;
var aux = aux2 = '';
var whichCode = (window.Event) ? e.which : e.keyCode;
if (whichCode == 13) return true; // Enter
if (whichCode == 8) return true; // Backspace
if (whichCode == 0) return true; // Null
if (whichCode == 9) return true; // Tab
key = String.fromCharCode(whichCode); // Get key value from key code
if ( strCheck.indexOf(key) == -1 ) return false; // Not a valid key
var x = new String(fld.value);
if ( key == '.' )
{
var exp = /\./;
var a = x.search(exp);
if ( a != -1 ) return false;
}
}
// samer code on change or on blur event
function allow2decimal(obj){
var v = parseFloat($(obj).val());
if (isNaN(v)) {
$(obj).value = '';
} else {
newVal = v.toFixed(2);
if(newVal >= 100){
$(obj).val( 100 );
}else{
$(obj).val(newVal);
}
}
}
//usage

For Loop in JavaScript - Lottery Website

I am trying to turn this code into a correct for loop statement, so that I can save my repetitions. I have tried my best to get it done, but I just don't know how I can write it correctly:
function myProg() {
var luckyNumber = 3;
var luckyNumber2 = 5;
var luckyNumber3 = 8;
var firstInput = document.luckForm.numberBox.value;
var secondInput = document.luckForm.numberBox2.value;
var thirdInput = document.luckForm.numberBox3.value;
var temp = '';
if (firstInput == luckyNumber && secondInput == luckyNumber2 && thirdInput == luckyNumber3 || firstInput == luckyNumber && secondInput == luckyNumber3 && thirdInput == luckyNumber2 || firstInput == luckyNumber2 && secondInput == luckyNumber3 && thirdInput == luckyNumber || firstInput == luckyNumber2 && secondInput == luckyNumber && thirdInput == luckyNumber3 || firstInput == luckyNumber3 && secondInput == luckyNumber && thirdInput == luckyNumber2 || firstInput == luckyNumber3 && secondInput == luckyNumber2 && thirdInput == luckyNumber)
{
alert('Congratulations! You got all 3 numbers correct. You\'ve won £1000!');
}
}

try something like this:
Array.prototype.getDuplicates = function() {
var cache = {}, results = [], that = this;
that.forEach(function(item, index) {
if(!cache.hasOwnProperty(item) && that.lastIndexOf(item) > index) {
results.push(item);
}
cache[item] = true;
});
return results;
}
var answers = [luckyNumber, luckyNumber2, luckyNumber3];
var indexes = [answers.indexOf(firstInput), answers.indexOf(secondInput), answers.indexOf(thirdInput)];
if(indexes.indexOf(-1) === -1 && indexes.getDuplicates().length === 0) {
// alert("Whatever");
}

Here's an example without using array. Input check was added.
function myProg() {
var numbersToMatch = 3;
var luckyNumbers = {n1: 3, n2: 5, n3: 8};
var firstInput = parseInt(document.luckForm.numberBox.value);
var secondInput = parseInt(document.luckForm.numberBox2.value);
var thirdInput = parseInt(document.luckForm.numberBox3.value);
if (isNaN(firstInput) || isNaN(secondInput) || isNaN(thirdInput)) {
alert('All inputs must be numbers!');
return;
}
var inputs = {n1: firstInput, n2: secondInput, n3: thirdInput};
var matches = {n1: false, n2: false, n3: false};
for (var i in inputs) {
for (var j in luckyNumbers) {
if ((!matches[j]) && (luckyNumbers[j] == inputs[i])) {
matches[j] = true;
numbersToMatch--;
break;
}
}
}
if (numbersToMatch == 0) {
alert('Congratulations! You got all 3 numbers correct. You\'ve won £1000!');
}
}
