call javascript function with parameter from code behind

Question

hii, i have to call a function to display a google map. the code is in .aspx page and i have to call the function from the corresponding .aspx.cs page. my problem is that when i call the function without any parameter it works fine and the map is displayed. however as soon as i try to send a string as argument the map doesnt get displayed. !!

Page.ClientScript.RegisterStartupScript(Type.GetType("System.String"), "addScript", "initialize()", true);

when i use this statement the map gets displayed. but when i write

Page.ClientScript.RegisterStartupScript(Type.GetType("System.String"), "addScript", "initialize('" + finaladd + "','" + name_and_add + "')", true);

its not worknig.. finaladd and name_and_add are two strings. they are however quite long ones.

its a string of name and address of employees and they are seperated by '~' . in the javascript function the string is split using .split method. — scooby

You'll have to debug it. Ignore how you generate the Javascript for now, and see if the Javascript itself is OK. Do the values look correct, and very important in Javascript, a single line? Use "\n" (backslash n, not a newline) if you need a newline. — bart

And, most importantly: does it work with manually entered Javascript? — bart

Make sure that both finaladd and name_and_add are properly escaped. In this case you need to make sure that the strings don't contain any single quote ' character.

The easiest way to accomplish this is a simple .Replace("'", @"\'") on both variables.

Backslashes need to be escaped, too.
