comparison of two variables using match

[newphpcoder]

Hi,Good day!I have problem in checking if the two values of variables is match or like.sample 1:in this sample 1 my condition works fine.

lot_number = LO130227003lot_number_scan = LO130227003if(lot_number === lot_number_scan){alert('correct');}else{alert('wrong');}

sample 2:in this sample 2 my condition did not work.

lot_number = LO130227003-LO130228001lot_number_scan = LO130227003 if(lot_number === lot_number_scan){alert('correct');}else{alert('wrong');}

I tried to find the solution in this problem but I can't find the same problem.I want to happen is:

if(LO130227003-LO130228001 LIKE OR Match LO130227003){alert('correct');}elseif(LO130227003-LO130228001 LIKE OR Match LO130227003LO130228001){alert('correct');}else{alert('wrong');}

I don't know what syntax should I used.here is my code:

function sequence(varid){      var a=  varid.indexOf("/")  var b=  varid.slice(0,a);   b =  parseInt(    c= (b+1)var f = varid.slice(a); if (window.event.keyCode==13 || window.event.keyCode==10) { var lot_number = document.getElementsByName("lot_number")[b].value; var lot_number_scan = document.getElementsByName("lot_number_scan")[b].value;var counting = document.getElementsByName("lot_number_scan");counting = counting.length; var newid = c + f if(c == counting) {  document.getElementById("issued_by").focus();    } else {  //----In this part I need to check if lot_number like lot_number_scan if(lot_number === lot_number_scan)	   {  document.getElementById(newid).focus();	 } else{    document.getElementsByName("lot_number_scan")[b].value = '';    document.getElementsByName("lot_number_scan")[b].focus(); } } }}

I hope someday can help me to fix this problem.Thank you so much.

Work this into your code somewhere:

var lot_number = "LO130227003-LO130228001";var lot_number_scan = "LO130227003";var match = lot_number.match(lot_number_scan)

Notice that you are matching strings. They probably come out of your scanner and DB as strings.

in your second sample, your can't subtract mixed value variables (strings and numbers) and expect it to work like an arithmetic equation.
