Hey web masters you guys have done a great job answering my web site building questions I have another one?

Question

I since starting my own first web site, have been right clicking on ever web site I go to and hitting view source to check out the code and tags used to make great well known site. This in an attempt to learn html. What I have noticed is a lot of tags with java script. What is java script.. it was my understanding that websites on the www is written in html. Is Java script better than html or does it work with html? Perhaps Java script is used for special effects?

Also Does anyone the html code I can use to place and image on my website as thumb nail and write it so that when clicked on the image opens up bigger.

Also what is a mouse over?

Answer 1

Javascript is a language that can be used in or with HTML for client side scripting in the browser. It requires some programming skill and lots of research and patience to use it, but it can be very powerful in manipulating the objects on your page.

You can do the thumbnail thing with javascript by using an onclick event and writing the code to display a larger image if clicked.

Mouse over is an event that occurs or is called when you pass your mouse over the object for which the mouseover method is defined. You could use this to do the larger image thumbnail when the mouse hovers over the thumbnail instead of clicking.

Answer 2

I am feeling the same way - often. So just this morning I zeroed in on News and Events. I could have picked another topic instead. It doesn't filter out all the "does he like me?" and "homework help" questions... but I get a better slice than just the general, most recent questions. An alternative to Yahoo Answers? I don't know of any. Make the most of this. Or go to a very specific newsgroup that is just about your specialized topic.

Answer 3

JavaScript works on the client-side. In other words, it is something that your browser does and not necessarily the web server. JavaScript is used heavily in the interactive content on web pages.

Companies like Google use a method called AJAX that allows interactivity without the expense of server output unless needed.

Answer 5

Javascript works with HTML to provide some added functionality - popup boxes (annoying) and a lot of other pretty clever uses. Search around on the net for some JS tutorials to give you a good idea.

It would be something like this:



A mouseover is a JS event that happens when the user's mouse hovers over an element on your page.

Answer 6

I don't know a ton about JavaScript, but it is very useful in web design for certain things. However, it's by no means better than HTML. HTML and JavaScript are different languages and are used for different things. To set an image to a certain size, you can use . Of course, there may be an easier way to do this, I just always seem to do it the hard way

A mouse over is when a image, or text, changes its apperance when the viewer moves thier cursor over the object.

Answer 7

I'm sure you'll get some more detailed ("better" ) answers than mine downstairs. But basically, Javascript is it's own programming language (unrelated to "Java") which can be embedded in HTML or have it's own file which is "called" from HTML (for example from a form). It is used (as you suggested) to do things "dynamically" which would be hard or impossible to do just from HTML alone. Again, others have more experience than I, but basically from Java script the entire web page is one object with "pieces" that you can "call methods on" (do things with). This object model can respond to "events" (typing a key, clicking the mouse, moving the cursor somewhere). The neat thing is this can all be done by the browser, which is good, because you may not have access to the server to execute scripts. Someone will explain the mouse over better than I, but it is one of the "events", passing a mouse of a certain element in your web page.

if you want to learn about javascript, go to www.w3schools.com and click "Learn JavaScript". Remember, Javascript and JAVA are two different things.
