[SOLVED] Need help javascript posting vars

[Rodis]

Hello,

 

I am stuck for a few weeks now. i have a form that gets categorie's out of a database when i fill in the form and change the categorie the subcategorie changes to This is done by a javascript onchange and refresh the url so i can use the get to define which subcategorie belong to the categorie

 

<SCRIPT language=JavaScript>
<!--
function changecat(newcat) {
    exit=false;
    site = "index.php?option=link_toevoegen&cat="+(newcat);
    if (newcat!=0) {
    document.newlink.submit();
	top.location.href=site;
    } else {
    document.newlink.submit();
	top.location.href="index.php?option=link_toevoegen";
    }
}
-->	
</SCRIPT>

 

The problem here is that all the fields i filled in are empty again.

 

I thought this could be solved by adding a submit to the script so i can retreive the posted info into the fields again except nothing gets posted. Can someone help me and tell me how to keep the values in the form when i change categorie

Below my full test code.

 

<SCRIPT language=JavaScript>
<!--
function changecat(newcat) {
    exit=false;
    site = "index.php?option=link_toevoegen&cat="+(newcat);
    if (newcat!=0) {
    document.newlink.submit();
	top.location.href=site;
    } else {
    document.newlink.submit();
	top.location.href="index.php?option=link_toevoegen";
    }
}
-->

Fixed code:

 

function changecat(newcat) {
       exit=false;
       site = "index.php?option=link_toevoegen&cat="+(newcat);
       if (newcat!==0) {
       document.newlink.submit();
      top.location.href=site;
       } else {
       document.newlink.submit();
      top.location.href="index.php?option=link_toevoegen";
       }
   }

Hey thanks for your reply's but i can't see any difference in the fixed code except for the fact that there are less spaces in the 2 lines. Anyways this still doesn't work my script only changes the url on the onchange effect which is good cause it makes me get the right subcategories from the cats but i need it to submit my values already filled in and post them to the new url to so i can keep the values in the texterea's before submitting them to the database. each time i change the categorie the fields are emptied since the page is refreshed to. If i can get the script to post i can retreive the values and problem would be solved

[darkfreaks]

so the category thing is fixed but the submit thing dont work ???

 

ok halfway there. anyhow i just checked your JS on 3 different debuggers and nothing came up, got a link so i can test it out? otherwise i would say its out of my league i would have to let the regulars in here like rhodesea or MAQ help you out  :-\

[Rodis]

Whell thanks anyway if you can't help me.

 

I have tried several things and if i loose the location bit values do get submitted , but then i won't be able to get the categorie out of the url so the subcategories are displayed right. since it won't be dericted to the new url. it seems that only one is working at a time.

 

i have tried to change the submit part in hope it wil submit to site url but no luck and can't seem to find anything about in on the internet they eiterh submit or change url not both in one :-( I don't know how else is should do it

[Rodis]

Woowie i have found it i tried all weird things and combos like top.submit.location.href=site(); and so on turns out to be simple.

 

2 object in a fucntion only works foor the last one it seems but for since this may be usefull for others i got it working with this.

function changecat(newcat) {
    exit=false;
    site = "index.php?option=link_toevoegen&cat="+(newcat);
    if (newcat!=0) {
    document.newlink.action=site;
	document.newlink.submit();	
    } else {
	document.newlink.action="index.php?option=link_toevoegen";
	document.newlink.submit();
    }
}
