1. 字符串格式化
var hot_li_template = ‘<li><div class="li-out"><span class="last"><i>{0}</i></span><span class="name"><a href="{1}">{2}</a></span><span class="nums">{3}</span></div></li>‘
jQuery.format(hot_li_template, i + 1, url, data.title, numberScale(data.views));
ƒ (num) { var ret = num; if (num > 1000) { ret = (num / 1000).toFixed(1) + ‘k‘; } return ret; }
toFixed() 方法可把 Number 四舍五入为指定小数位数的数字。
