Zero infront of zipcode getting cut off, need help

Question

Not showing full zip code – I put in 07753 and it shows 7753 (missing the 0). Thank you for your help!
Here is my code:
var v7 = this.getField("ShipTo");
var v1 = this.getField("ZipPostal Code").value;
var v2 = this.getField("ZipPostal Code_2").value;
if(v7.value == "0")
    if(v1.length === 0)
      v1 = "";
    else
      v1 = this.getField("ZipPostal Code").value;
event.value = v1;
else if(v7.value == "1")
     if(v2.length === 0)
            v2 = "";
     else
            v2 = this.getField("ZipPostal Code_2").value;
event.value = v2;

You need to get the value of the field using the valueAsString field property:
var v1 = this.getField("ZipPostal Code").valueAsString;
var v2 = this.getField("ZipPostal Code_2").valueAsString;
