Question

–In the variable line below I declared a variable (xwid) as 690. But when I try the code by using the variable of $xwid, the width never updates. Any ideas?

$xwid=690;  // my var

// my code
$('.iframe-link').html( '<iframe src="reasons.html" frameborder="0" width=$xwid height="305" scrolling="auto">

Answer 1

Variables in Javascript are not declared this way

$xwid=690;     // wrong
alert($xwid);  // wrong

var xwid = 690;  // right
xwid = 690;      // right
alert(xwid);     // right

EDIT: Your code should look like thiis

var xwid=690;  // my var

// my code
$('.iframe-link').html('<iframe src="reasons.html" frameborder="0" width="'+xwid+'" height="305" scrolling="auto">');
