同上按钮实现

• 页面实现同上功能
  上面是一个下拉框和一个输入框
  下面同样也是需要实现一键同步，无需重复操作！

1 按钮 
<button id="butwar1" type="button" style="background-color: #ff9e08; color: #FFFFFF;font-size: 16px;margin-left: 0.4rem;">同注册地址</button>
2 js

/*同注册地址*/
    $("#butwar1").click(function () {
       // alert("de");
        var obj1 = document.getElementById("regAddressProvince");
        var obj1value = obj1.options[obj1.selectedIndex].value;
        var obj1name = obj1.options[obj1.selectedIndex].text;
        //  alert(obj1value+"hjh"+obj1name);

        if(obj1value != null || obj1name != null){
            var shengtext = document.getElementById("sheng");
            shengtext[0].value = obj1value;
            shengtext[0].text = obj1name;
        }

        var obj22 = document.getElementById("regAddressCity");
        var obj22value = obj22.options[obj22.selectedIndex].value;
        var obj22name = obj22.options[obj22.selectedIndex].text;

        if(obj22value != null && obj22name != null){
            var shitext = document.getElementById("shi");
            shitext[0].value = obj22value;
            shitext[0].text = obj22name;
        }
        var obj33 = document.getElementById("regAddressCountry");
        var obj33value = obj33.options[obj33.selectedIndex].value;
        var obj33name = obj33.options[obj33.selectedIndex].text;
        if(obj22value != null && obj22name != null){
            var xianqvtext = document.getElementById("xianqv");
            xianqvtext[0].value = obj33value;
            xianqvtext[0].text = obj33name;
        }
        var registeredAddress = $("#registeredAddress").val();
        if(registeredAddress != null && registeredAddress != null){
            $("#postaddress").val(registeredAddress);
        }
