Jsp in Javascript || Javascript in Jsp

[Samer, qc]

Hello,
I'm VERY new in JSP. I have a javascript function that dynamically creates new rows in a table already defined in the html. I want to put a variable defined in jsp into the javascript function, how do i do that? Here is the javascript function:

function newRow(){
if (Txt_Barcode.value == ""){
alert("Please enter a barcode");
}else if (getValue(Loc) == ""){
alert("Please choose a location");
} else {
// Declare variables and creates a row.
var oRow, oCell;
var i, j, k;
var stock = new Array;
  // in the below quote marks is where the JSP variable 
  //is going to be for example: <%= variable %>
  stock["0,0"] = "";
  stock["0,1"] = "";
  stock["0,2"] = "";
  stock["0,3"] = "";
  stock["0,4"] = "";
  stock["0,5"] = "";
// Insert rows and cells into the first body.
oRow = oTBody1.insertRow();
  oCell = oRow.insertCell();
  oCell.innerText = stock[0 + "," + 0];
  //if barcode variable.length == 12 then red else black
  //don't know if this code will work
  if (oCell.innerText.length == 12) {
   oCell.style.color = "red";
  } else {
   oCell.style.color = "black";
  }
  
 for (j=1; j<5; j++){
  oCell = oRow.insertCell();
  oCell.innerText = stock[0 + "," + j];
  }
  oCell = oRow.insertCell();
  oCell.innerHTML = stock["0,5"]; 
}
}

thanx,
Samer

If you want to display the value of any jsp variable (assuming a proper toString() conversion) just type <%= variable %> inline to the javaScript code.
ie.
var javascriptVar = '<%= jspVariable %>';
