Question

In my javascript file I have the following line:

<div id="mygraph" style="width:200px;height:100px;"></div>

I’d like to set the width and height values in the style tag from two variables that take their values from the corresponding functions:

var my_width = getWidth();
var my_height = getHeight();

How can I accomplish that? I’m missing the correct syntax. Thank you in advance…

Answer 1

The following assumes that my_height and my_width returned by your functions are plain numbers:

document.getElementById('mygraph').style.height = my_height + "px";
document.getElementById('mygraph').style.width = my_width + "px";
