ok here is my problem. I want my cooking forum to have a input box like below when you type in how many people you want it to serve and then it changes the amount of ingredients you need:

An Example HERE!!!

Try it out and see what i mean!! I want this to be in my posting area and in when viewing the topic. Thanks!

Oh yeah and here is the code:

Code:

<div class="servings"><input type="text" name="scale" size="1" value="6" />  <input type="hidden" name="mid" value="63990" /><input class="button" type="submit" value="change servings" /> <input type="button" class="button" onclick="location.href = 'http://www.cdkitchen.com/recipes/recs/39/All-Time-Favorite-Puff-Pudding93117.shtml'" value="reset" /></div></form><p><span class="bold red">Ingredients:</span><br /><span style="font-family:arial;" id="nointelliTXT">"ingredients here"</span>

That would be easy in javascript, give all ingredients a special class or id, then you the onchange event in javascript to alter those fields.

Code:

function getElementsByClassName(needle) {
   var my_array = document.getElementsByTagName("*");
   var retvalue = new Array();
   var i;
   var j;

   for (i=0,j=0;i<my_array.length;i++) {
   var c = " " + my_array[i].className + " ";
   if (c.indexOf(" " + needle + " ") != -1) retvalue[j++] = my_array[i];
   }
   return retvalue;
}

Code:

   tests = getElementsByClassName("runningman");
   pos = p*2;
   for (i= 0; i < tests.length; i++)
   {

         tests[i].style.left = pos +"px";

   }

are snippets of how to do bits of this.

It is only a code snippet showing techniques one would use in javaScript. A full javascript program is needed. _________________ Family Friendly Shareware \| \| Web Design/Services \| Free Forums forum.myfreeforum.org

The thing about programs is that with few exceptions they need to be written to fill the need, they are not just available off the shelf. What you are asking for is maybe 2 hours work for a javascript programmer, well less than that for a good one, but it would need installing etc. _________________ Family Friendly Shareware \| \| Web Design/Services \| Free Forums forum.myfreeforum.org

How do you program without programming? What is the sound of one hand clapping? If you need programming done, you are going to have to: 1) Learn programming. 2) Find a forum member prepared to do it for you. 3) Offer to pay a programmer. Not every bit of customization can be done with a portal check box option. _________________ Family Friendly Shareware \| \| Web Design/Services \| Free Forums forum.myfreeforum.org

Can do it? or would do it for free? There may be students on this forum who are learning javascript and would therefore probably charge pocket money rates for a little job where they would learn something. _________________ Family Friendly Shareware \| \| Web Design/Services \| Free Forums forum.myfreeforum.org

I think Symon is just posting a tutorial. You have to be real here. Life in the real world of web sites is not free. People will not build you a programmed site for nothing unless they are a member of your site and keen to do it, or want the experience. _________________ Family Friendly Shareware \| \| Web Design/Services \| Free Forums forum.myfreeforum.org

I realise that. I have a member on another javascript forum helping me at the moment. He has got everything sorted pretty much apart from one problem. I was just wondering how to put a .js file or javascript code onto a forum. I will post the code for the javasript once it is finished. _________________ Click Here--> Cook Like a Pro in a Day!!!
