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"); //Here r1 stores the ad heading with html tags
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 = Strip(r1); //I need a strip html javascript function here
Response.Write("<td valign='top' width=400 rowspan=2>"+r1+"</td>"); //Header
Hope this makes sense.
Thanks

oops...that was kind of sloppy of me. I'm too used to C/C++
This function works and was tested
Call it like this in your code:
r1 = RS("AdHead");
r2 = stripHTML(r1);
Response.Write("<td valign='top' width=400 rowspan=2>"+r2+"</td>");
This is the new function
function stripHTML( oldString )
{
var newString = "";
var inTag = false;
for( var i = 0; i < oldString.length; i++ )
{
if( oldString.charAt(i) == '<' ) inTag = true;
if( oldString.charAt(i) == '>' ) {
inTag = false;
i++;
}
if( !inTag ) newString += oldString.charAt(i);
}
return newString;
}
I'm still getting object expected error.
This is the function code within HTML <head>
<script language="JavaScript" type="text/javascript">
<!--
function stripHTML( oldString )
{
var newString = "";
var inTag = false;
for( var i = 0; i < oldString.length; i++ )
{
if( oldString.charAt(i) == '<' ) inTag = true;
if( oldString.charAt(i) == '>' ) {
inTag = false;
i++;
}
if( !inTag ) newString += oldString.charAt(i);
}
return newString;
}
//-->
</script>
And then I'm calling it like so inside a table within ASP tags
<%
.
.
r1 = Q("AdHead");
r2 = stripHTML(r1); //If I comment out this line I dont get an error but tags are still included.So I'm guessing it's the way the function is being called ??
Response.Write("<td>"+r1+"
.
%>
THANKS FOR ALL THE HELP SO FAR :D
Ok as I'm sure you can guess by my name I'm new to this ASP, javascript stuff. I've been messing around with it but getting now where
Here is my entire page of code can you show me where I should call the function.
Cheers

Like this. As I said, you're trying to call a server-side function in your asp, you had declared the function as a client-side function.
<body TOPMARGIN="0" LEFTMARGIN="0" MARGINWIDTH="0" MARGINHEIGHT="0"">
<%
function stripHTML( oldString )
{
var newString = "";
var inTag = false;
for( var i = 0; i < oldString.length; i++ )
{
if( oldString.charAt(i) == '<' ) inTag = true;
if( oldString.charAt(i) == '>' ) {
inTag = false;
i++;
}
if( !inTag ) newString += oldString.charAt(i);
}
return newString;
}

this function should do the trick:
function stripHTML( oldString )
{
var newString = "";
var inTag = false;
for( var i = 0; i < oldString.length; i++ )
{
if( oldString[i] == '<' ) inTag = true;
if( oldString[i] == '>' ) inTag = false;
if( !inTag ) newString += oldString[i];
}
return newString;
}
