Need syntax help  -    Cell.Text = <script Language = 'JavaScript'.........

I have a C# server control that contains a footer. The footer code is HTML w javascript rollover events. (The HTML code also calls an exernal js file for it's functions). This code works fine from a  regular aspx page, so the actual code should not be the problem, just the syntax of trying to embed javascript this way. Because of using the HTML in this manner, I have to take out all inside double quotes("). This is causing a proplem when trying to insert the javascript code because 1 line of it already has embeded quotes, and in javascript you cannot embed the same type of quotes. Is there any work around for this? Here is the code:


The HTML part of the code below works as intented, but here is the original JavaScript(aspx) page code:
<td width="103"><a href="../pages/ContactUs.aspx" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Contact US','','../images/controls/footer/contact_on.gif',1)"><img name="Contact US" border="0" src="../images/controls/footer/contact_off.gif" width="119" height="43"></a></td>

                  
Here is what I am trying to do: The problem is probably with this line that already had embeded quotes- see original code above:       +"onMouseOver='MM_swapImage('Contact US','','../images/controls/footer/contact_on.gif' ,1)'>"            

this.Rows[0].Cells.Add(new TableCell());      
            
this.Rows[0].Cells[0].Text="<script language='JavaScript' src='http://localhost/PLTP/Scripts/ContactMeRollover.js'></script>"            
 +"<TABLE WIDTH='751' BORDER='0' CELLPADDING='0' CELLSPACING='0' background='../images/controls/footer/AIS_49.gif'>"
+"<TR>"
+"<TD COLSPAN='2' vAlign='baseline' rowSpan='1'>&nbsp;"
+"</TD>"
+"<TD COLSPAN='18' bgcolor='#ffffff' background='../images/controls/footer/AIS_49.gif' width='659'><table width='98%' border='0' cellspacing='0' cellpadding='0' align='center' height='67'><tr>"
+"<td colspan='3'><FONT face='Verdana' size='2'>Simply click on the Contact Us button and a licensed AIS representative will help you with your quote.&nbsp; We can communicate with you either over the phone or via email.</FONT></td>"
+"<td width='103'><a href='../pages/ContactUs.aspx' onMouseOut='MM_swapImgRestore()'"
+"onMouseOver='MM_swapImage('Contact US','','../images/controls/footer/contact_on.gif' ,1)'>"
+"<img name='Contact US' border='0' src='../images/controls/footer/contact_off.gif' width='119' height='43'>"
+"</a>"
+"</td>"
+"</tr>"
+"</table>"
+"</TD>"
+"</TR>"
+"</TABLE>";
Again, the overall code and the HTML code work as designed..the Javascript doesn't work. I have gotten javqscript to work in this manner before but I did not have to deal with double embeded quotes.

you need to escape if you want to go below " and '

you can do \" and \\'

For example

string script = " alert(\"foobar\"); "

" -- will be interperted first
\" , ' -- will be interperted second
\\\", \\' -- will be interperted third

To fix your code:

+"<td width='103'><a href='../pages/ContactUs.aspx' onMouseOut='MM_swapImgRestore()'"
+"onMouseOver=\"MM_swapImage('Contact US','','../images/controls/footer/contact_on.gif' ,1)\">"
+"<img name='Contact US' border='0' src='../images/controls/footer/contact_off.gif' width='119'
