Use Below script on change of field value
This script will help you to restrict end user to provide currency value in "$0.00" format
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Type appropriate comment here, and begin script below
var cost_field = g_form.getValue('cost_field');
cost_field = cost_field.trim();
// first character should be dollar sign
var firstChar = cost_field.substring(0, 1);
if (firstChar != '$' || firstChar != 'second' || firstChar != 'third') {
alert("Please enter cost_field in $0.00 format along with the currency symbol");
g_form.setValue("cost_field", oldValue);
return;
}
// characters after the $ sign should be numerics
var cost_fieldType = isNaN(cost_field.substring(1));
if (cost_fieldType == true) {
alert("Please enter cost_field in $0.00 format along with the currency symbol");
g_form.setValue("cost_field", oldValue);
return;
}
// entered value should have a decimal point
var num = cost_field.substring(1);
if (num.indexOf('.') == -1) {
alert("Please enter cost_field in $0.00 format along with the currency symbol");
g_form.setValue("cost_field", oldValue);
return;
}
// there must be 2 digits only after the decimal
var decNum = num.substring(num.indexOf('.') + 1, num.length);
if (decNum.length != 2) {
alert("Please enter cost_field in $0.00 format along with the currency symbol");
g_form.setValue("cost_field", oldValue);
return;
}
}
