The following code creates a list, which is done by loops, and parts of it should be manipulated by javascript. Therefore I need an individual ID with every loop, so that only some parts are manipulated. That ID comes from the variable "OptionTopID". The "OptionTopID" is concatenated with the variable "optionTopNumber", so that I get a combination of text and number. The concatenated "OptionTopID" then is transmitted to the javascript function "Write Value". But now I have a strange problem with the transmission. The alert in the "WriteValue" function only displays the none-concatenated value "optionTop" without the number. Why? If the number isn't transmitted to the javascript function, the whole thing doesn't work. Do you have any idea why ID is transmitted in the none-concatenated version?



HTML with Smarty:
Code:


{block name="frontend_index_header_javascript_jquery" append}
   <script type="text/javascript" src="{link file='frontend/_resources/javascript/project.js'}"></script>
{/block}

   {assign var='optionTopNumber' value=1}
   

   {foreach from=$sArticle.sConfigurator item=sConfigurator}
      
      {assign var='optionTopID' value='optionTop'}
      {$optionTopID|cat:$optionTopNumber}
         
         
      
         <div {if $configValue.selected}selected="selected"{/if} value="{$configValue.optionID}" class="option_config_top" id="{$optionTopID}">
                  {$configValue.optionname}{if $configValue.upprice} {if $configValue.upprice > 0}{/if}{/if}
         </div>
         
         
         
         {foreach from=$sConfigurator.values item=configValue}
               <option value="{$configValue.optionID}" class="option_config" onclick="WriteValue('{$configValue.optionname}', '{$optionTopID}')">
                  {$configValue.optionname}{if $configValue.upprice} {if $configValue.upprice > 0}{/if}{/if}
               </option>
         {/foreach}
         
         {assign var='optionTopNumber' value=$optionTopNumber+1}
         
   
   {/foreach}



javascript:
Code:

function WriteValue (obj, id) {
   
   alert(id);
   $("#" + id).text(obj);
   $("#" + id).slideUp("slow");
};

Quote:
{$optionTopID|cat:$optionTopNumber}

does not assign the appended version to optionTopID

Use
Code:
{assign var='optionTopID' value="optionTop`$optionTopNumber`"}


See http://www.smarty.net/docs/en/language.syntax.quotes.tpl

Thanks. But when I use that solution, then the javascript function doesn't work. There's no alert anymore. I don't know why.

Update: If I change the javascript function like you can see below, than there's the alert "undefined".

Code:

function WriteValue (obj, id) {
   
   alert(id);
   $("#" + id).text(obj);
   $(".option_config").slideUp("slow");
};

I solved the problem. I shouldn't have used "id" for a javascript-variable. If I change it to something else, it works.
