How to calculate the dimensions of a svg
element consistently between browsers? In fact the only one not responding consistently is Firefox.
It would be interesting to see the reason for getBoundingClientRect
disparities in different browsers as well.
I tried to compare the results using getBoundingClientRect
and getComputedStyle
. getComputedStyle
is consistent but does not exist in IE8.
var svg = document.querySelector('svg');
var gBCR = svg.getBoundingClientRect().width;
var bBox = svg.getBBox().width;
var gCS = window.getComputedStyle(svg, null).width;
console.log('gBCR: ' + Math.round(gBCR) + ' - gCS: ' + gCS + ' - bBox: ' + Math.round(bBox));
// Resultados:
// Firefox: gBCR: 142 - gCS: 400px - bBox: 363
// Chrome: gBCR: 400 - gCS: 400px - bBox: 363
