經常使用jQuery 方法

//強制給數字補全小數點
function toDecimal2(x) {
    var f = parseFloat(x);
    if(isNaN(f)) {
        return false;
    }
    var f = Math.round(x * 100) / 100;
    var s = f.toString();
    var rs = s.indexOf('.');
    if(rs < 0) {
        rs = s.length;
        s += '.';
    }
    while(s.length <= rs + 2) {
        s += '0';
    }
    return s;
}

//查詢全部列表並追加到div中
    var list = data.doctorList;
    var html = '';
    for(var i = 0; i < list.length; i++) {
        var imgUrl = list[i].doctorImg;
        var docName = list[i].doctorName;
        var docDev = list[i].doctorDevlement;
        var hosName = list[i].hospitalName;
        console.log("圖片地址" + imgUrl);
        console.log("醫生名稱" + docName);
        console.log("科室" + docDev);
        console.log("醫院名稱" + hosName);

        html += '<div class="weui-jiaj-panel">' +
            '<a href="department/change_doctor_info.html" class="weui-jiaj-a-color" data-id="doctorInfo">' +
            '<div class="weui-media-box weui-media-box_appmsg">' +
            '<div class="weui-media-box__hd">' +
            '<img class="weui-media-box__thumb" src="' + imgUrl + '" />' +
            '</div>' +
            '<div class="weui-media-box__bd">' +
            '<h4 class="weui-media-box__title">' + docName + '</h4>' +
            '<p class="weui-media-box__desc">' + docDev + '</p>' +
            '<p class="weui-media-box__desc">' + hosName + '</p>' +
            '</div>' +
            '<div class="weui_jia_cell_ft"></div>' +
            '</div>' +
            '</a>' +
            '</div>';
    }

    $('#tab1').append(html);

//點擊button，獲取每一個按鈕的名稱
    $('.depart-btn').click(function(){
        var value = $(this).attr('name');  //$(this)表示獲取當前被點擊元素的name值
        console.log("當前button的名稱爲" + value);
    })

//獲取URL中參數的方法
function getQueryString(name) {
    var reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');
    var r = window.location.search.substr(1).match(reg);
    if (r != null) {
        //return unescape(r[2]);  註釋：ECMAScript v3 已從標準中刪除了 unescape() 函數，並反對使用它，所以應該用 decodeURI() 和 decodeURIComponent() 取而代之。若是繼續使用unescape函數,則在獲取中文參數時會致使獲致              到的參數亂碼，所以下面是改
      return decodeURI(r[2]);
    }
    return null;
}

//若是url中的參數是toutiaoForwardId與shareShortCode
//下面的方法是調用getQueryString獲取Name
//http://127.0.0.1:8020/wx/admin/department/change_doctor_info.html?toutiaoForwardId=121f1a


var toutiaoForwardId = getQueryString('toutiaoForwardId');
var shareShortCode = getQueryString('shareShortCode');

//點擊按鈕，獲取input的值，並經過url傳遞給下一個頁面
$('#saveHospitalName').click(function(){
        var hospitalName = $('#hospitalName').val();
        console.log("醫院名稱" + hospitalName);
        window.location.href = "/wx/admin/department/change_doctor_info.html?hospitalName=" + hospitalName;
    });

//彈框，點擊保存按鈕，把彈框中的數據保存在當前頁面
$('#saveDoctorName').click(function(){
        var doctorName = $('#doctorName').val();  //input的值
        $('#doctorNameShow').html(doctorName);  //當前頁面值的保存位置
    })

//在一個div中動態添加BTN

var doctorTitelListData = doctorTitel.doctorTitelList;
    var $titleHtml = '';
    for(var a = 0; a < doctorTitelListData.length; a++){
        var titleName = doctorTitelListData[a].doctorTitelName;
        $titleHtml += '<button class="weui-btn weui-btn_mini weui-btn_default title-btn"' + 'name=' + titleName + '>' + titleName + '</button>';
    }
    
    $('#doctorTitleBox').append($titleHtml);
