I need to remove fractional addresses from a street address input line. I need to allow for people who enter strings like the following:

• 1600 1/2 Main St
• 1600 3/4 Main Street
• 1600.5 Main St
• 1600.75 3rd Street

The above examples should be output as follows:

• 1600 Main St
• 1600 Main Street
• 1600 Main St
• 1600 3rd Street

Here's what I've started with:

var ele = document.getElementById('billing_address_1');

if (typeof(ele) != 'undefined' && ele != null) {
    function fractionalAddress() {
        originalStreet = ele.value;

        //
        //var punctuationless = originalStreet.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"");
        //var finalStreet = punctuationless.replace(/\s{2,}/g," ");

        finalStreet = originalStreet.replace(/\s.*\//, '');          

        ele.value = finalStreet;
        console.log(originalStreet);
        console.log(finalStreet);
    };

    ele.addEventListener("change", fractionalAddress);
}

I haven't quite figured out how to grab the character after the slash but before the space. So, the above converts "1600 3/4 Main Street" into "16004 Main Street." Close, but not quite there!

What am I missing? Would it be better to split this into an array?

This works for me with the help of regex101.

var addresses = `1600 1/2 Main St
1600 3/4 Main Street
1600.5 Main St
1600.75 3rd Street`

console.log(
addresses.replace(/ ?\d\/\d?|\.\d{1,}/g,"")
)

breakdown:

This regex seems to work.

finalStreet = originalStreet.replace(/\s*(\d+\/\d+|\.\d+)\s/g, '');   

A tip for the future, you can use a site like regex101. to test and edit your regex
