so here's the thing - google maps crashes browsers on slower machines when you try and map too many locations at once. we're allowing users to select real estate listings to map by providing a checkbox beside each of the listings that show up through their search. they can display up to 99 listings on a page and i just know somebody is going to sit there and click all of them (because i haven't let them have a "map all" function).

is there any way for me to have all the checkboxes become inactive after the user selects, say, 20 items?

a better solution would be to allow them to check as many as they want and then only show them 20 - with a next button for the others

that's not a bad strategy - any other alternative ideas

Just let it crash and laugh at them. Just put a little disclaimer by the submit button.

Yes, you 'can' disable them but, javascript is a bitch when dealing with various browsers.

Why are we giving ideas to google?

Just run a counter, when the clicked event happens ++ it, when it hits 20, prevent the checkmark from happening. I believe you can do that by just returning false from the clicked event. I may be wrong. When they click a clicked one, -- the counter, and you're good to go. And show them in a lable the number of items they have left they can check.

just make sure it works in IE. Anything else doesn't really matter.

to do it properly you should probably use JavaScript if it's detected as enabled, and dirty, slow postback if not (probably mentioning in a big red warning box that it's using postback because they have javascript disabled)

If they're using Google Maps, they're going to have to have JavaScript on anyway.

well we all use it, but only 1% of the visitors to our site do

yeah they do, matter of fact it's all the java that winds up crashing it

thanks for the input guys. right now i'm thinking that the "let them crash it" is the right approach to take
