hi guys, can you give me some ideas?

suppose i have a page with the following text:

"Singapore, officially the Republic of Singapore, is an island country off the southern tip of the Malay Peninsula, 137 kilometres (85 mi) north of the equator, in the Southeast Asian region of the Asian continent. It is separated from Malaysia by the Straits of Johor to its north, and from Indonesia's Riau Islands by the Singapore Strait to its south. Singapore is the world's fourth leading financial centre[11] and a cosmopolitan world city, playing a key role in international trade and finance...."

and i want it to show and replace dynamically as the page loads every instance of Singapore, Malaysia, Indonesia, Malay Peninsula with a hyperlink to their specific page.

sample links:
Singapore, Malaysia, Indonesia, Malay Peninsula,
can you please give me some ideas guys? thanks

Ideas:

1. A server side language replace before loading the page.
or
2. A regular Expression replace on the text by accessing the element that holds the text.



Code: 
var link_singapore="<a href='[URL unfurl="true"]http://www.Singapore.com'>Singapore</a>";[/URL]
str.replace(/singapore/gi, link_singapore);
...

Since I don't know what your page looks like its hard to say, but as an example:
Code: 
<html>
<head>
<title></title>
</head>
<body>
<div id="mytext">
Singapore, officially the Republic of Singapore, is an island country off the southern tip of the Malay Peninsula, 137 kilometres (85 mi) north of the equator, in the Southeast Asian region of the Asian continent. It is separated from Malaysia  by the Straits of Johor to its north, and from Indonesia's Riau Islands by the Singapore Strait to its south. Singapore is the world's fourth leading financial centre[11]  and a cosmopolitan world city, playing a key role in international trade and finance....
</div>
</body>
</html>

And you want to replace the places with the links:

Code: 
[gray]
<html>
<head>
<title></title>
[red]<script type="text/javascript">
function replace_links(){
var links=new Array();
links[0]="<a href='[URL unfurl="true"]http://www.Singapore.com'>Singapore</a>";[/URL]
links[1]="<a href='[URL unfurl="true"]http://www.Malaysia.com'>Malaysia</a>";[/URL]
...

var thetext=document.getElementById('mytext');
thetext.innerHTML.replace(/singapore/gi, links[0]);
thetext.innerHTML.replace(/malaysia/gi, links[1]);
}
</script>[/red]
</head>
<body [red]onLoad="replace_links();[/red]>
<div id="mytext">
Singapore, officially the Republic of Singapore, is an island country off the southern tip of the Malay Peninsula, 137 kilometres (85 mi) north of the equator, in the Southeast Asian region of the Asian continent.

</div>

hi vacunita, thanks for that code but i can't seem to make it to show/replace the text with a hyperlink.

Although the java script example should work this is a requirement that would be better suited to a server side solution.
performing the search & replace serverside would ensure the feature worked for all useres including those whose borwsers do not support java script or have java script switched off.

Sorry, I typed that straight into the reply box, and had a few typos. I also hoped you removed the "..." before trying to run it as that would have caused some errors.

This should now work.
Code: 
<html>
<head>
<title></title>
<script type="text/javascript">
function replace_links(){
var links=new Array();
links[0]="<a href='[URL unfurl="true"]http://www.Singapore.com'>Singapore</a>";[/URL]
links[1]="<a href='[URL unfurl="true"]http://www.Malaysia.com'>Malaysia</a>";[/URL]
...
var thetext=document.getElementById('mytext');
var reps="";
alert(thetext.innerHTML);
thetext.innerHTML=thetext.innerHTML.replace(/singapore/gi, links[0]);
thetext.innerHTML=thetext.innerHTML.replace(/malaysia/gi, links[1]);
...
}
</script>
</head>
<body onload="replace_links();">
<div id="mytext">
