let body = document.querySelector('body')
        body.width = '100%'
        for (let i = 1; i < 10000; i++) {
            let str = '&#'+i+';'
            let sm = str.big()
            let st = document.createElement('span')
            st.innerHTML = sm
            st.style.fontSize = '30px'
            body.appendChild(st)
        }

结果如下
