JS驼峰与下划线互转

1.下划线转驼峰

function underlineToHump(s){
    var a = s.split("_"); var result = a[0]; for(var i=1;i<a.length;i++){ result = result + a[i].slice(0,1).toUpperCase() + a[i].slice(1); } return result }

调用后 underlineToHump('anshd_cdjop')结果是anshdCdjop

2.驼峰转下划线

function humpToUnderline(str){
    return str.replace(/([A-Z])/g,"_$1").toLowerCase() }
