js部分代码如下：

function address(){
    /*请在此补充代码*/ 
    var proArr = ["Beijing", "Tianjin", "Hebei", "Henan"];
    var cityArr = ["Chaoyang", "Xichengqu", "Shijiazhuang", "Handan", "Qingxiqu", "Wuqingqu", "Zhengzhou", "Kaifeng"];
    var province = document.getElementById("province");
    var city = document.getElementById("city");
    selectAdd(province,proArr,proArr);
    selectAdd(city,cityArr, cityArr);
}
function selectAdd(obj,name,value){
	/*请在此补充代码*/  
	for(var i=0; i<=name.length; i++){
		obj.options.add(new Option(name[i],value[i]));
	}
}

html代码部分如下：

<html>
	<head>
		<title></title>
		<script src="javaScript1.js" type="text/javascript" charset="utf-8" async defer></script>
	</head>
	<body onload = "address()">
		<form>
		     省份：
		     /*请在此补充代码*/ 
		     <select name="province" id="province"></select> 
		     市/区：
		     /*请在此补充代码*/ 
		     <select name="city" id="city"></select>
