Jquery is designed so that you don't have to add JavaScript into you html(I think their aim is like css). its a module that you have to initialize first to use. here is a link to the tutorial instead of adding a onclick to each tag you just use "$("#whole").click(function () {" and it runs the code inside that function. where "#whole" is the ID of the html tag. well you'll get the picture after going through the tutorial. I suggest you browse through the "API Reference". just one tip when you initialize it use this kind of code. "var variable_name = jQuery.noConflict();" you could use any name for the variable_name and use that instead of the $ symbol. it prevents you code from having conflicts with other jquery codes. just in case you use it with other jquery codes made by other people. 2. since its not inside any function it should be accessable any where in the code. |
