使用 JavaScript 更改 SVG 对象的高度和宽度

Question

I want to change height and width of an svg object on a button click. I tried it but it doesn't work:

function modify() {
    document.getElementById('circle1').style.height = "10px";
    document.getElementById('circle1').style.width = "10px";        
}

Answer 1

In SVG width and height of <rect> elements are attributes and not CSS properties so you'd need to write

document.getElementById('cercle1').setAttribute("height", "10px");

similarly for the width.
