function cssStyle2DomStyle(sName) {
        if(sName.charAt(0) === '-'){
            sName = sName.substring(1);
        }
        var str = sName.split("-");
        console.log(str);
        var result = '';
        var temp = ''
        if(str.length === 2){
        result  = str[0]+str[1].charAt(0).toUpperCase()+str[1].substring(1);
        }else{
            var res = str[0];
            console.log(res,99);
            for(let i = 1;i<str.length;i++){
                temp  += str[i].charAt(0).toUpperCase()+str[i].substring(1);
            }
            result = res + temp;
        }
        return result;
    }

先判断字符串 之后再做处理
