hahaha, all good manits hard to impart context sometimes, and if you were in front of me, you'd a been laughing while i asked the question. the reason being, i had been debugging my VERY FIRST ajax stuff for ~7 hrs, and you shouldnt try to pen an email at that point. hennyway.
i am using ajaxCfc to update the innerHtml value for a div. i have it jacked into my cfc which returns the data perfectly, displays it perfectly and all is well! however :) i want to setInterval()-ize it. and the way i work on things, i was going to try to pull it off myself with little tidbits of help. i understand and can read *most* javascript, i can write SOME, but its limited. i can usually hack multiple things together and come up with a perfect situation, or i resort to the list (charlie griefer) ahhaah anyway, i was working on getting the # of elements that i had so that i could do the - for loop - to start all of the setInterval() ping's to the cfc to update the divs at which point i emailed the list since i was stuck at ground zero on the update to my currently working schtuff. i realize that i could do two columns of radio buttons, a on/off column if you will on the page, and have the user click from "no" to "yes" but id rather just use checkboxes and name/id them all the same value and have the form.field value come back as a comma delimited list of values, i dont care about the order of them, just the inclusion of them is all i need. anyway, i can do it all in coldfusion with a mix of javascript for the ajax stuff, but id rather try to make it all javascript. you know, i could: 1. get the count, by the record set that comes back (supplant the value in the for loop with cf) 2. build a javascript array with cf code that does the iterating (clunky but it works) 3. and then do the setinterval() etc all that would be fine, but id rather do it with javascript :) tw On Mon, Feb 9, 2009 at 5:47 PM, Michael Grant <[email protected]> wrote: > > Yw rasta, > > I mean no offence by over explaining.
