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()
}
