初始化56个民族下拉框

这里给出两种方式，我比较喜欢第一种

第一种：在js中定义数组

var nations = ["汉族","蒙古族","回族","藏族","维吾尔族","苗族","彝族","壮族","布依族","朝鲜族","满族","侗族","瑶族","白族","土家族",
               "哈尼族","哈萨克族","傣族","黎族","傈僳族","佤族","畲族","高山族","拉祜族","水族","东乡族","纳西族","景颇族","柯尔克孜族",
               "土族","达斡尔族","仫佬族","羌族","布朗族","撒拉族","毛南族","仡佬族","锡伯族","阿昌族","普米族","塔吉克族","怒族", "乌孜别克族",
              "俄罗斯族","鄂温克族","德昂族","保安族","裕固族","京族","塔塔尔族","独龙族","鄂伦春族","赫哲族","门巴族","珞巴族","基诺族"];
function initNations(){
	var staff_nation = document.getElementById("staff_nation");
	for ( var i in nations) {
		staff_nation.add(new Option(nations[i], i));
	}
}

第二种：直接写在html标签内
