Question
Strip HTML tags from data in database rows
Hi,
I'm trying to do something like this, but I need help.
I have a table which contains Adverts for a magazine, there is a column cotaining Ad Headings. I have also stored HTML tags around the ad headings in the table. Each advert is displayed on many pages on my site.
But I want to display an ad on some pages without the HTML tags. How do I strip the html tags from the database for this page without changing the ad in each other page. All my code is ASP and javascript.
This is my code that outputs the adverts, where html tags are included.
r1 = Q("AdHead")
Response.Write("<td valign='top' width=400 rowspan=2>"+r1+"</td>"); //Header ok but tags included
But when I do this
r1 = Q("AdHead")
r1 = Replace(r1, " ","")
Response.Write("<td valign='top' width=400 rowspan=2>"+r1+"</td>"); //Header
I get this error
Microsoft JScript runtime error '800a138f'
Object expected
?
Hope this makes sense.
Thanks

NB: javascript, Jscript and java are all totally different from each other.
Don't store the HTML in the table. Reverse the logic and add the HTML to the pages it's needed on. It's a rule of thumb for me not to store formating in the database, or in my com objects. Might be a bit of extra typing in the beggining to update those pages but worth it in the end as your db data will be more flexible.

you need to use Regular expressions to remove html tags.

Removing All HTML Tags from a String Using Regular Expressions
--------------------------
If you need to remove all HTML tags from a file e.g. to display all HTML tags on a Web page, but as the raw HTML tags (like showing <B>bold</B> as opposed to bold). The script presented in this artcle will accomplish these tasks with ease!
To accomplish this, included in this article is the code to a function, ClearHTMLTags, which has the following definition:
function ClearHTMLTags(strHTML, intWorkFlow)
Where strHTML is the string to be cleared of HTML tags and intWorkFlow determines how to clear the HTML tag... a value of 0 simply strips the HTML tags while a value of 1 displays the HTML tags as text in the document (like showing <B>bold</B> as opposed to bold).
The code for ClearHTMLTags is presented below... there is also a live demo to give the script a run. Note that the ClearHTMLTags function uses regular expressions to ease the hunt and removal of HTML tags...
