vue中如何给DOM元素添加属性

Question

attr () {var r = ('<canvas>您的浏览器暂时不支持canvas，请选用现代浏览器！</canvas>').attributes('width', a).attributes('height', n)cvs.empty().append(r)}这样会报错

Answer 1

var r = document.createElement('canvas')

r.setAttribute('width', a)

r.setAttribute('height', n)

r.textContent = "您的浏览器暂时不支持canvas，请选用现代浏览器！"

cvs.empty().append(r)
