有一组json数据在进行for循环插入到dom时，
var tt = data.serach_house_price;//json数据 var html3 = ''; for(var i in tt) { html3 +='
输出结果如图所示，最后一个key循环到第一个位置了，如何对它们按大小进行重新排序呢？

var tt = { '0-40': '40万以下', '40-60': '40-60万', '60-80': '60-80万', '80-100': '80-100万', '100-150': '100-150万', '150-200': '150-200万', '200-300': '200-300万', '300-400': '300-400万', '400': '400万以上', } var sortKeys = Object.keys(tt).sort(function(i1,i2){ return i2.split('-')[0] - i1.split('-')[0] }); var html3 = ''; for(var i=0, len=sortKeys.length; i'+tt[sortKeys[i]]+'\n'; } console.log(html3);
这样看看满足吗？
