问题 I've just recently discovered the power of jQuery. Just a quick question though. What is a replacement for onclick="DeleteSomething('THE ID NUMBER LOADED IN BY SERVER SIDE')" ? Is there even a way somehow to pass custom information such as an ID to a jquery onclick? Or do i have to stay with the old fashioned way? Thanks a lot! Adam 回答1: I usually use a rel="" for some extra data i might need attached to the button or whatnot. for example <input class="btnDelete" rel="34" value="Delete" />

问题 Greetings I am using the jquery disable on submit plug-in but I have a problem. If I disable the submit buttons they dont get passed back to the server so I cant tell which button was pressed.

问题 I want to pass over parameters in the click function. var albums = document.getElementsByClassName("album"); for(var i = 0; i<albums.length; i++){ document.getElementById(albums[i].id).addEventListener("click", goAlbum(albums[i].id), false); } however, the function "goAlbum" gets excecuted when it is created, and then the function won't excecute anymore. what am I doing wrong? 回答1: goAlbum was getting executed because you called the function.
