How To Create an External JS File?

[laura]

Hi,

Can anyone give instructions, or know where I can find instructions, on creating an external java script file? Plain, precise, non-techy language would be best in my case, but any help at all will be appreciated.

Thanks!

Do you mean write an external javascript from scratch or adapt an existing internal one to be used as an external one? From scratch is easy,


alert('Done!');Simply save the above code to a file and name it 'alertdone.js'
Add this code to the head of your html page:


<script src="alertdone.js" type="text/javascript"></script>Adapting an internal script is similar but can get tricky depending upon the script. Many can be adapted simply by removing the '<script>' and '</script>' tags from the code, saving that code to a file and giving that file a name say, 'myscript.js', then putting this in the head or body (depending upon where the script was originally meant to go) of your page:

<script src="myscript.js" type="text/javascript"></script>

Many can be adapted simply by removing the '<script>' and '</script>' tags from the code [...]It should also be noted that SGML comments (<!-- ... -->), should be removed. So, given:


<script type="text/javascript">
<!-- Hide from browsers

/* Script content */

// -->
</script>only


/* Script content */should be saved. The SGML comments shouldn't be present anyway, but many old scripts haven't been updated to omit them.
