How to autofill 0(zero) at the back after the decimal point in jquery? Like if user insert not enough digit then it will auto fill with zero(0) at the back.
Example:
User Insert - 0.12345
Then it must add to - 0.12345000

What I have tried:

This is what I try but I just know how to set the dot symbol can insert only once in the text field.

$("#Lat").on("keypress keyup blur",function (event) {
    $(this).val($(this).val().replace(/[^0-9\.]/g,''));
           if ((event.which != 46 || $(this).val().indexOf('.') != -1) && (event.which < 48 || event.which > 57)) {
               event.preventDefault();
           }
       });

$("#Lng").on("keypress keyup blur",function (event) {
    $(this).val($(this).val().replace(/[^0-9\.]/g,''));
           if ((event.which != 46 || $(this).val().indexOf('.') != -1) && (event.which < 48 || event.which > 57)) {
               event.preventDefault();
           }
       });

JavaScript

var val = $(this).val(); // the decimal entered
var desired_length = 12; // the length it should 'pad' to - that's the correct term

for (var i = val.length; i < desired_length; i++)
{
    val += '0';
}

Be aware that if you then set the textbox's value to val, using $(this).val(val); then it will alter the caret position.
