Seat Selection

Hello, This is my first post here!

I'm trying to create a bit of Ajax which will allow people select tables on my picture by clicking on the tables allowing them to table of their choice. I am thinking of using image maps for table selection. I am not sure how to write the ajax in order to have the selected tables change color, indicating that they are taken. Does anyone have any recommendations for the image manipulation. I would rather not create a server side script to edit the image and have the user reload the picture every time they make a selection, I expect most people will change their table selections a few times before selecting the table of their choice.

Thanks a lot,
James

hi ...

welcome to TSDN ...

do you have some coding done already, that you could post here? the general idea would be to pass something to the server that identifies the selection the user made onclick on the imagemap ... i think you know how the ajax-call works with a query-string? ... you may use an attribute to store something at the area which is clicked and pass that value wth the ajax-call's query-string ...

kind regards

I am not worried about getting the information into the ajax, but how do I use ajax to alter the image so that when a seat is taken the table's color turns black instead of white.

Thank you!
James

hmm ... i would recommend to experiment with css-divs and some transparent styles to achieve your goal, in case you want to avoid image-replacing ...

Thank you, you more/less answered my question. I was curious if their was a simple technique that I simply missed. Since their is not one, I can do an image replace, but not use a new image for their selection.

Thank you,
James

glad to hear that your are on a track for your problem ... javascript has very, very poor image-handling-abilities ... you may replace the src-attributes or set some style properties, use transitions or something ... but it has no 'real' image-manipulation-abilities ...

post back to the forum anytime you have more questions ...

kind regards
