How to prevent JavaScript conflict in custom server control (when added more than once to a page)Ie. unless the JavaScript, included with the server control (which might reference ID's in the generated HTML), somehow knows which control it belongs to - A problem will occur if two or more of the same control are included on the same page. It's no problem ensuring that unique ID's are generated for each use of a particular control - But then what with the JavaScript referencing those ID's? Are there any general Pattern&Practice for solving this? I've searched high and low on the net without much luck. Would very much appriciate some pointers to some links that dig into this subject.. /MGKR Well, you can always generate a separate function for each instance of the
control and give the function a name like <CONTROLID>_myfunction(). However, if the JavaScript is being used with instances of the same control there is usually a way to write it so that the same JavaScript can be used for all instances, often by passing a few extra parameters. If you tell us exactly what your control's JavaScript is supposed to do we may be able to make a few suggestions. Good Luck!

(http://msdn.microsoft.com/en-us/library/system.web.ui.clientscriptmanager.aspx) It allows to manage client side scripts and in particular to register a script once (using http://msdn.microsoft.com/en-us/library/system.web.ui.clientscriptmanager.aspx or other registration checking methods)... If this is not a script registration problem please be a bit more specific about the exact problem... -- Patrice "MGKR" <no-reply@spam.com> a écrit dans le message de groupe de discussion : #I5UC4siJHA.1***@TK2MSFTNGP05.phx.gbl...Show quoteHide quote > How do you go about solving this? > > Ie. unless the JavaScript, included with the server control (which might > reference ID's in the generated HTML), somehow knows which control it > belongs to - A problem will occur if two or more of the same control are > included on the same page. > > It's no problem ensuring that unique ID's are generated for each use of a > particular control - But then what with the JavaScript referencing those > ID's? > > Are there any general Pattern&Practice for solving this? > > I've searched high and low on the net without much luck. > > Would very much appriciate some pointers to some links that dig into this > subject.. > > > /MGKR >
