Implementing Angularjs version 1.xx
var processedInput = text.replace(/[^0-9.]/g, '')
.replace(/\B(?=(\d{3})+(?!\d))/g, ",");
if(processedInput!="")
processedInput="$"+processedInput;
Input = 123456789, Desired Output = $123,456,789
However, I am looking for the following desired output:
Input = 20.56, Desired Output = $20.5600
Input = 20, Desired Output = $20.0000
Input = 20.567, Desired Output = $20.5670
Transforming strings into floats without the use of filters.
Utilize the parseFloat function to convert a string to a float value, then apply the toFixed(4) method.
var text = "20";
var transformedInput = text.replace(/[^0-9.]/g, '')
.replace(/\B(?=(\d{3})+(?!\d))/g, ",");
if(transformedInput!="")
transformedInput="$"+parseFloat(transformedInput).toFixed(4);
console.log(transformedInput);Implement Angular currency filter
<span data-ng-bind="'987654321'| currency : '€' : 2 "></span>
I hope this code snippet works effectively for your needs.
var input = document.getElementById('myInputBox'),
btn = document.getElementById('formatButton');
btn.addEventListener('click', formatData);
function removeCurrencySymbols(str) {
return str.replace(/\,|\$/g, '');
}
Number.prototype.format = function() {
return this.toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");
};
function formatData() {
var num = removeCurrencySymbols(input.value),
val = (Number(num).toFixed(4)).toString().split('.'),
decimal = '';
if (num.indexOf('.') > -1) {
decimal = '.' + val[1];
}
input.value = '$' + Number(val[0]).format() + decimal;
}<input type="text" id='myInputBox' value="" />
<input type="button" id="formatButton" value='Get Output'>If you're looking to format numbers in JavaScript, the Number#toLocaleString method is a perfect option for you:
var numbers = [20.56, 20, 20.567];
var formattedNumbers = numbers.map(number =>
number.toLocaleString('en-US', {
style: 'currency', // this represents money
currency: 'USD', // for US dollars
// calculating the digits before the decimal point
minimumSignificantDigits: ((~~number) + '').length + 4
})
);
