I use a classifieds script. This script uses tpl files. In one of the tpl files, I created a javascript function at the top between {literal} ... {/literal} tags. My function has too many lines (1700 so far). I used lots of document.getElementById( functions and lots of if controls like below :

I know I shouldn't use so many lines. But I am not good at coding and it worked nice until it reached 1700 lines. After 1700 lines (file size 180 kb), even I add one more line containing document.getElementById(.. it started not to work, doesn't display the form in the browser although there are no error messages or warnings. If I remove the line, it works again and displays the form. There is no error in the last line. Because I used hundreds of before.
What I am trying to do is to use a search form with nested select boxes. When a select box is clicked, I make the others hidden.

Does usage of document.getElementById so much cause this result? Or is there a limitation about the max lines or characters for a javascript function, or is there a limitation for these in a tpl or literal tags? Or should I change something in php.ini? This 1700 lines function is called in several select boxes in a search form.

I know it is very difficult to answer such a question but I am trying my chance in case the answer may be simple. Smile

<script type="text/javascript">
function optionCheck(){
var option = document.getElementById("maincategories").value;
var option1 = document.getElementById("estate1").value;
var option2 = document.getElementById("estate2").value;
var option3 = document.getElementById("estate3").value;
var option4 = document.getElementById("estate4").value;
var option5 = document.getElementById("estate5").value;
var option6 = document.getElementById("estate6").value;

if(option == "6"){
document.getElementById("estate0").style.display = 'block';
document.getElementById("estate").style.display = 'block';
document.getElementById("cars0").style.display = 'none';

if ...

if ...




<div class="containertable">
<form action="search.php" ondblclick="submit()" name="itemForm" id="itemForm" method="get">
<script language="javascript">
<input name="do_search" type="hidden" value="Search" />
<table cellspacing="3" border="0">
<td><span style="text">{$smarty.const.LA_SEARCH}</span> </td>
<td><input id="searchword" name="searchword" size="25" class="txt" value="{$searchword}" /></td>

<td><span style="text">{$smarty.const.LA_S_CATEGORY}</span> </td>

<div style="float:left" id="main">
<select id="maincategories" name="catid_search" onchange="optionCheck()" class="regionselect" size="14">
<option value='0'>{$smarty.const.LA_ALL}</option>
<option value="6">Real Estate</option>
<option value="7">Cars</option>
<option value="8">Computers/option>
<option value="9">Electronics</option>
<option value="10">Internet</option>
<option value="11">Services</option>
<option value="15">Pets</option>
<option value="18">Goods</option>
<option value="19">Other</option>


Thank you for your help.

I'm not shure into which sort of limit you are running.

You could try not to use {literal} but replace the javascript {,} by {ldelim},{rdelim} and see if it helps
