keyword highlighting

[jsbinus]

Hi...Can anyone tell me what is the best way to highlight all the "keywords" in a page. Assuming that the keywords are passed through a query string. Can we achieve that by using javscript, if we can, how can we call from the server side script


Thanks

I think it's better to do it in server-side alone, like what this forum does. What's your server-side language?

in vbscript, you'd do it like this:

kw = request.querystring("keyword")
content = replace(content,kw,"<font color=""red"">" & kw & "</font>")
response.write(content)

or use span tag instead since font tag is deprecated

<span style="color:red">keyword</span>

glenngv: Shouldn't the double quotes be escaped? Or just use single-quotes inside replace...

[glenngv]

you mean like this?

<%
kw = request.querystring("keyword")
content = replace(content,kw,"<span style='color:red'>" & kw & "</span>")
response.write(content)
%>

you could do it that way, but to stick to standards, you should use double quotes in HTML attribute values. And to do that inside vbscript string literals, you need to double the quotes to escape it.

<%
kw = request.querystring("keyword")
content = replace(content,kw,"<span style=""color:red"">" & kw & "</span>")
response.write(content)
%>

Oh alright, I was just wondering... Haven't done much coding in VBScript, JavaScript is so much better.
