才學JS不久，剛好項目需要一個京東地址選擇器，所以嘗試著寫了一個，dom獲取較為復雜，純粹使用自己了解到的東西

依賴

//css是用rem寫的


//mui提供的城市js

           地址
        

頁面內JS

mui.init();
mui(".mui-scroll-wrapper").scroll({
    scrollY: true, //是否豎向滾動
    bounce: true //是否啟用回彈
});


var p = "";  //文字
var num = "";  //value值

var address = document.getElementById("address")
address.addEventListener("tap",function(){
    mui("#addSelect").popover("show");
    addS();
})
function giveValue(){
    address.innerHTML = p;
    mui("#addSelect").popover("hide");
    console.log(p);
    console.log(num);
}

調用函數

function addS(){
    
    
    var slider = mui("#slider").slider();
    var selectNav = document.getElementById("selectNav");
    var selectNavLi = selectNav.getElementsByTagName("li");
    var oneUl = document.getElementById("select-con-1");
    var twoUl = document.getElementById("select-con-2");
    var threeUl = document.getElementById("select-con-3");
    var item1 = document.getElementById("item1");
    var item2 = document.getElementById("item2");
    var item3 = document.getElementById("item3");
    var index1 , index2 , index3;
    for( i=0 ; i1){
                    p = active[0].innerText + active[1].innerText + "多個區域";
                }else{
                    p += text;
                }
            }
        }
        
        
//        賦值
        giveValue();
    })
}
