function() {
var address = $("#postcode").val();
var postcode = address.split(' ');
postcode = "Postcode:"+postcode[(postcode.length-2)];
return postcode;
}
This JavaScript function extracts a postcode from an online form when a user submits a query. I am looking to modify it to retrieve the postcode without the last 2 characters. For instance, if the postcode is "SP10 2RB", the function should return "SP102".
To cut out specific parts of a string in JavaScript, you can utilize the functions substring(), substr(), or slice().
To achieve your desired result, simply slice the string:
return address.slice(0, -2);
// For example
address = "example";
// Expected output
"exam"
Here is a helpful function for extracting postal codes:
function extractPostalCode(address)
{
var formattedAddress = address.replace(' ','');
formattedAddress = formattedAddress.substr(0, formattedAddress.length-2);
return formattedAddress;
}
alert(extractPostalCode('SP10 2RB'));
