 Posted: Fri Jul 29, 2005 9:28 am Post subject: Looping through smarty generated checkboxes with javascript |
 |
|
Hi all, sorry for my newbie-ness.
Ive been looking through the forum but cannot find a solution to my prob as follows:
I have a set of keywords that are generated via smarty code:
| Code: |
<form action="<!--[$action_link]-->" method="post" name="deleteKeywords" onSubmit="return checkSelected()" >
<!--[html_checkboxes name="keywords" options=$keywords separator="<br />"]-->
<input type="submit" value="next">
</form> |
they appear and work fine as expected on the front end.
However my problem is need to loop through these checkboxes because I have to check whether at least one of them is checked in order to proceed.
My javascript code is doing the following which incidentally works for smarty radio buttons, but does not work for the checkboxes:
| Code: | <script>
function checkSelected()
{
form = document.deleteKeywords;
var keywordSelected;
for (i=0;i<form.keywords.length;i++)
{
if (form.keywords[i].checked)
{
keywordSelected = true;
}
}
if (keywordSelected) {
return true;
} else {
alert("<!--[pnml name=_CHKKEYWORD]-->");
return false;
}
}
</script> |
Any ideas anyone? 
Thanks in advance for any response  |

did it a bit of manipulating of some other code i found and got a work around but im sure there is an easier way. here is the updated javascript code i used because i could find out how to get the checkboxes names which smarty generates as "keyword[]".
so i did walk through the form elements instead 
| Code: | <script>
function checkSelected()
{
var theform = document.deleteKeywords, count = 0;
var len = theform.length;
var keywordSelected;
for (count=0; count<len; count++)
{
if (theform[count].type == 'checkbox')
{
if (theform[count].checked)
{
keywordSelected = true;
}
}
}
if (keywordSelected) {
return true;
} else {
alert("<!--[pnml name=_CHKKEYWORD]-->");
return false;
}
}
</script> |
