script met class implementeren
Aangezien ik mijn formulieren met de class formhandler maak probeer ik het hier ook werkend in te krijgen, maar dit lukt niet.
ik heb het idee dat het scripje bij onkeyup niet wordt aangeroepen.
maar wat hiervan de oorzaak is daar kan ik niet achter komen.
dit is wat ik werkend heb:

<script type="text/javascript">
function plaatje(e, id){
var dir = "images/";
var ext = ".JPG";
if(e.value.length > 3 && e.value >= 1600 && e.value <= 1605){document.getElementById(id).src = dir + e.value + ext;}
if(e.value.length <= 3 && e.value < 1600 ){document.getElementById(id).src = dir + 'error.gif';}
}
</script>
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje" />
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje2')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje2" />
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje3')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje3" />
function plaatje(e, id){
var dir = "images/";
var ext = ".JPG";
if(e.value.length > 3 && e.value >= 1600 && e.value <= 1605){document.getElementById(id).src = dir + e.value + ext;}
if(e.value.length <= 3 && e.value < 1600 ){document.getElementById(id).src = dir + 'error.gif';}
}
</script>
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje" />
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje2')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje2" />
<input type="text" name="tekst" onkeyup="plaatje(this, 'mijnplaatje3')" size="4" maxlength="4" />
<img src="images/error.gif" id="mijnplaatje3" />
en dit is wat ik met formhandler heb gemaakt maar niet af krijg.
kan iemand misschien kijken wat ik fout heb gedaan? of iets wat ik zou kunnen proberen?

dit scripje laat een aantal divjes zien aan de hand van de input van een selectfield. dus is 1 geslecteerd dan is div 1 te zien, is 2 geselecteerd dan zijn div 1 en 2 te zien. enz enz enz.
dit scripje heb ik zonder formhandler wel aan de praat.
maar in formhandler lukt het me niet helemaal.
dat wil zeggen dat ik geen foutmeldingen krijg maar dat de divjes ook niet worden weergegeven. dit is wat ik werkend heb:

en dit is wat ik in formhandler heb. ik krijg dus geen foutmeldingen.
maar er gebeurt voor de rest ook niks, zit de fout in de div jes? of kan de functie de waardes van het selectfield niet uitlezen?
iemand een idee?

javascript: is net als bijvoorbeeld http:, https: of ssh: de aanduiding voor het protocol in de URL. onchange moet geen URL bevatten, maar geldige javascript-code.
Maar heeft voor de werking voor de rest niks uitgemaakt, of heeft me niet op meer ideen gebracht.
iemand nog meer ideen/suggesties?
dat kan wel maar is wel veel werk denk ik...
ik heb hier wel de url zodat je kan zien hoe het er online uit ziet:
het werkende gedeelte zonder de class:
http://www.vanderwaal.info/test3.php
wat ik tot nu toe heb met de class formhandler maar niet werkend krijg:
http://www.vanderwaal.info/orderinvoer/hide2.php
ik heb hem in IE getest maar zie niks!
welke browser gebruik jij?
iemand een idee hoe ik het dan ook in IE werkend kan krijgen?
http://www.vanderwaal.info/orderinvoer/hide2.php
Vervang:
Code (php)
1
$form -> selectField("numflowers", "numflowers", $numflowers, FH_NOT_EMPTY, 0, 0, 1, 'onChange="javascript: ShowMenu(document.getElementById(\'numflowers\').value,\'divColor\', 2);"');
eens door
Code (php)
1
$form -> selectField("numflowers", "numflowers", $numflowers, FH_NOT_EMPTY, 0, 0, 1, 'onChange="javascript: ShowMenu(this.options[this.selectedIndex].value,\'divColor\', 2);"');
Zie voor meer informatie deze pagina op Quirksmode.
er was een tabel niet goed afgesloten waardoor de de divjes niet konden worden weergegeven.
bedankt voor jullie reacties!!!!
