1.根据时间生成m位随机数,最大13位随机数,并且不能保证首位不为0. 例子: function ran(m) { m = m > 13 ? 13 : m; var num = new Date().getTime(); return num.toString().substring(13 - m); } console.log(ran(5)); 2.根据Math的random函数生成的随机数截取m位,生成随机数最大不超过16位,能保证首位不为0. 例子 function rand(m) { m
1. 最笨的办法 function get() { var s = 22.127456 + ""; var str = s.substring(0,s.indexOf(".") + 3); alert(str); } 2. 正则表达式效果不错 <script type="text/javascript"> onload = function(){ var a = "23.456322"; var aNew; var
