The following code is used for validating the numbers with digit grouping(ie. Convert the digits into like Currency $) using Javascript.
For ex,
1. If you given the input 20000, it generates the output $20,000.00
2. If you given the input 2555, it generates the output $2,555.00
And also it is having some validation, whether if the input is number or not
function digitGrouping(digit) {
var obj = document.getElementById(digit);
var digit = document.getElementById(digit).value;
var isGroup = "1234567890,.$";
var chk;
for(var i = 0; i <= digit.length-1; i++) {
if(isGroup.indexOf(digit.substring(i, i+1)) != -1) {
chk = true;
} else {
chk = false;
alert("Not a valid number \nNumber format should be like this 1,000,000.00");
return;
}
}
if(chk == true) {
var newDigit = digit.split(".");
var newDigit1 = newDigit[0];
var newDigit2 = newDigit.length > 1 ? '.' + newDigit[1] : '00';
var commas = /\,/g
var isDigit = /^[1-9]/;
var isDollor = /^\$/;
if(isDigit.test(newDigit1) || isDollor.test(newDigit1)) {
if(commas.test(newDigit1)) {
newDigit1 = replaceCommas(newDigit1.replace(/\,/g, ""));
newDigit1 = replaceCommas(newDigit1.replace(/\$/g, ""));
} else {
newDigit1 = replaceCommas(newDigit1);
newDigit1 = replaceCommas(newDigit1.replace(/\$/g, ""));
}
if (newDigit[1]) {
obj.value = "$" + newDigit1 + newDigit2;
} else {
obj.value = "$" + newDigit1 + "." + newDigit2;
}
} else {
alert("Not a valid number, All number cannot be Zero \nNumber format should be like this 1,000,000.00");
}
} else {
alert("Not a valid number \nNumber format should be like this 1,000,000.00");
}
}
function replaceCommas(digit) {
var regExp = /(\d+)(\d{3})/;
while(regExp.test(digit)) {
digit= digit.replace(regExp, '$1' + ',' + '$2');
}
return digit;
