  • Javascript Help!

    I'm trying to accomplish padding PID3 with zeros when PID3 is less than 8 digits in length. Ultimately the MRN field should always be 8char

    Here's the code that I'm struggling with. When ran the variable "val" is not recognized.

    //Pad with 0's
    function padleft(val, ch, num) {
    var re = new RegExp(".{" + 8 + "}$");
    var pad = "";
    var val = msg['PID']['PID.3']['PID.3.1'].toString();
    }
    if (val.length < 8)
    do {
    pad += 0;
    }while(pad.length < 8);

    return re.exec(pad + val);

    SAMPLE MSG:
    MSH|^~\&|ONLINE_ORDERS|WMH|||20080104171437||ORM^O 01|1|P|2.3|||NE|NE
    PID|||909-2||TEST^JACK|||||B|123 B STREET^^INDIANAPOLIS^IN^46202||()||||||999-99-9999

    Try:

    Code:
    var padleft=function(val, ch, num) {
       var re = new RegExp(".{" + 8 + "}$"«»);
       var pad = "";
       var val = msg['PID']['PID.3']['PID.3.1'].toString();
       if (val.length < 8)
       do {
         pad += 0;
       }while(pad.length < 8);
       return re.exec(pad + val);
    }

      How would you return this padded value to a variable?
