How to help (function calls)

Copy linkTweet thisAlerts:

Since I am not a full time programmer, I need a little help in find a way to call a javascript from a function. Here is an example of what I am trying to do:

function update_info()
{
<script> language=”JavaScript” type=”text/JavaScript” src=”infobar1.js” </script>
}

Is this correct? Looks like it should work but does not.

document.write(<script> language="JavaScript" type="text/JavaScript" src="infobar1.js" </script>)

[CODE]
<html>
<head>
<title>My Page</title>
<script language="JavaScript" type="text/JavaScript" src="infobar1.js">
</script>
</head>
<body>
<!-- content goes here -->
</body>
</html>
[/CODE]

Then you can call a function when you need it
[CODE]
 <input type="button" name="btnButton" id="btnButton" onclick="update_info();" />
[/CODE]

There are other ways of calling a function. It depends on what you are doing.

@mrhooNov 28.2006 — [CODE]function update_info(srcpath){
var pa= document.getElementsByTagName('head')[0];
var el= document.createElement('script');
el.setAttribute('type','text/javascript');
el.setAttribute('src',srcpath);
pa.appendChild(el);
return el;
}[/CODE]

This appends a new script with src=srcpath to the document head.

The first time you need to use something from that script you will

need to set up a polling timer to check for its availability- it may take a second or more to download. I'd set an upper limit, in case of network troubles.

Alternatively, you could use AJAX...

@ashbrookauthorNov 28.2006 — Thanks all for the current replies. The reason for using a function call is that I need to update the information once a minute using the "window.settimeout" parameter. I was calling the function from the "onload" command. If there is a better way, I am open for suggestions.

@mrhooNov 28.2006 — The better way is to use a database and call the query with AJAX,

with a php (or asp) fallback

Success!
