"Javascript", How to use the passed arguement in the function

fazthegreat · 15-Feb-2006, 05:08 AM #1

Hi, I'm trying to write a little function that will accept an arguement as follows:

function FloorPlan(plan)

{
FloorPlanWindow= window.open("","FWin1","width=550,height=550,left=100,top=0");
FloorPlanWindow.document.write("<HTML><HEAD><\/HEAD><BODY BGCOLOR='e0d9aa'><center><IMG SRC='plan'><\/center><br><center><a href='javascript:window.close()''>Close Window<\/a><\/center><\/BODY><\/HTML>");

FloorPlanWindow.focus();
}

I'm calling this function from this link:
<a href="javascript:FloorPlan('images/A1_1br-1ba.jpg')">C1</a>

What am i doing wrong coz the passed arguement does not work.How do i use "plan" (passed arguement) in the code to write html to the window.

Please someone help!
Thanks

Hi,
The mistake you are making is that you are placing the variable "plan" directly inside the quotes, so it is interpreted as a string literal (not as a variable)

Example:

Code:

var Test="fazthegreat";
document.write("Hello 'Test' !");

Will output:
Hello 'Test' !

but this on the other hand:

Code:

var Test="fazthegreat";
document.write("Hello '" + Test + "' !");

will output:
Hello 'fazthegreat' !

ie: If you are going to use a variable inside a string in a Javascript function you must split the string at this variable and add the variable as a separate value (without quotes) within the string then add the rest of the string as another separate value with...

"Hello " + variable + " !" is correct
"Hello variable !" will make javascript think that variable is part of the literal string...

Hope that helps you

and use the code tags next time as they really help to differentiate code from the rest of the post
