Javascript function called from code behind file

[moni]

Hi..

I am trying to use javascript for google maps display.


If I call the javascript function from my aspx file I use:


<input type="text" id="addresstext" value="Huntington Avenue,
Boston, MA" name="yourName" style="width: 287px" />
<input type="button" id="addressclick" value="Display Map"
onclick="showAddress(addresstext.value)" /><br />


and it works.


But using the Response.Write from the aspx.cs file it
does not display it. I need to pass an argument to the function
call.Am I passing the value wrongly??


I am calling it this way:


Response.Write("<script
language='javascript'>showAddress("+getAddress+");</script>");


where, getAddress is the comma-seperated Address string.


This is not displaying the map, I am creating using Javascript.

I have also tried all combinations of singel quotes, and double quotes
wrt calling the javascript function


Thx

Most likely that Response.Write has rendered your JavaScript block outside
HTML-tag.
Best way to add JavaScripts from codebehind is to use
RegisterClientScriptBlock

this.RegisterClientScriptBlock("jsGoogleMap","<script

language='javascript'>showAddress("+getAddress+"</script>");

Oh....yeah, don't inject javascript into your ASPX page using
Response.Write, there are much better methods for doing this. Have a look at
RegisterStartupScript, etc. Those are going to work with your ASP.net page
infrastructure. What you're doing is going to place script *outside* HTML
blocks and will probably never work - and if it does, it's by chance.

Note that in ASP.Net 2.0, this method (and related) has been superceded by
the ClientScriptManager's methods for doing the same things. The
ClientScriptManager is a property of the System.Web.UI.Page class, and is
exposed in the Page.ClientScript property. See:
