Get width/height of SVG element
What is the proper way to get the dimensions of an svg
element?
http://jsfiddle.net/langdonx/Xkv3X/
Chrome 28:
style x
client 300x100
offset 300x100
IE 10:
stylex
client300x100
offsetundefinedxundefined
FireFox 23:
"style" "x"
"client" "0x0"
"offset" "undefinedxundefined"
There are width and height properties on svg1
, but .width.baseVal.value
is only set if I set the width and height attributes on the element.
The fiddle looks like this:
HTML
<svg id="svg1" xmlns="http://www.w3.org/2000/svg" version="1.1">
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="1" fill="red" />
<circle cx="150" cy="50" r="40" stroke="black" stroke-width="1" fill="green" />
<circle cx="250" cy="50" r="40" stroke="black" stroke-width="1" fill="blue" />
</svg>
JS
var svg1 = document.getElementById('svg1');
console.log(svg1);
console.log('style', svg1.style.width + 'x' + svg1.style.height);
console.log('client', svg1.clientWidth + 'x' + svg1.clientHeight);
console.log('offset', svg1.offsetWidth + 'x' + svg1.offsetHeight);
CSS
#svg1 {
width: 300px;
height: 100px;
}
Use getBBox function
http://jsfiddle.net/Xkv3X/1/
var bBox = svg1.getBBox();
console.log('XxY', bBox.x + 'x' + bBox.y);
console.log('size', bBox.width + 'x' + bBox.height);
FireFox have problemes for getBBox(), i need to do this in vanillaJS.
I've a better Way and is the same result as real svg.getBBox() function !
With this good post : Get the real size of a SVG/G element
var el = document.getElementById("yourElement"); // or other selector like querySelector()
var rect = el.getBoundingClientRect(); // get the bounding rectangle
console.log( rect.width );
console.log( rect.height);
