Hopefully simple solution

[sylunt1]

Hello...

I am trying to do some basic js stuff and need a little help. I have the following code;

[code]
<script LANGUAGE="JavaScript">
<!-- HIDE FROM OTHER BROWSERS

var side = new Array("Oki 590-88", "Oki 590-79", "Oki 473C");
var top = new Array("Manufacturer", "Description", "OEM Price", "HDC Price");
                            

var manu = new Array("IBM", "IBM", "Okidata", "Okidata");
var part = new Array(976, 726, 590, 473);
var fits = new Array("2380, 2381, 2390, 2391", "3262, 5262", "590, 591", 120);
var price = new Array("6.00", "6.25", "16.50", "10.75");

document.write("<table border=1 width=95% cellspacing=0 height=1 cellpadding=1><tr><th>Manufacturer</th><th>Part</th><th>Fits Model</th><th>Price</th></tr>");

for (i=0; i<manu.length; i++){

  
document.write("<tr><td>", manu[i], "</td>",
"<td>", part[i], "</td>",
"<td>", fits[i], "</td>",
"<td>", price[i], "</td></tr>")


}
document.write("</table>");

// STOP HIDING FROM OTHER BROWSERS -->
</SCRIPT>
[/code]

It does what it is supposed to do, but what I want is this:
on the left column - if the item repeats I only want the word to show up one time - like this...

item 1 product info price
[empty] product info price
item 2 product info price
[empty] product info price

How can I make it do that?


Thanks,
Chris

try this in your for loop...

[code]
var last = "";
var display = "";
for (i=0; i<manu.length; i++){
if (last == manu[i]) {
  display = manu[i];
  last = manu[i];
}
else {
  display = "";
}
  
document.write("<tr><td>", display, "</td>",
"<td>", part[i], "</td>",
"<td>", fits[i], "</td>",
"<td>", price[i], "</td></tr>")


}
[/code]

All I added was a variable to track the last product shown and then an if statement to see if the next product is the same as the last product shown. If it is, then no product name is printed.

Almost... now none of the manufacturers show up... its all blank...

yes the solution is simple (i hope it works for ya :)

if(i !=0 && part[i-1] != part[i]){
display part[i]
}else{
display nothing
}
