常用jQuery 方法

//强制给数字补全小数点
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;
}

//查询所有列表并追加到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("图片地址" + imgUrl);
        console.log("医生名称" + docName);
        console.log("科室" + docDev);
        console.log("医院名称" + 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);

//点击button，获取每个按钮的名称
    $(‘.depart-btn‘).click(function(){
        var value = $(this).attr(‘name‘);  //$(this)表示获取当前被点击元素的name值
        console.log("当前button的名称为" + value);
    })

//获取URL中参数的方法
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]);  注释：ECMAScript v3 已从标准中删除了 unescape() 函数，并反对使用它，因此应该用 decodeURI() 和 decodeURIComponent() 取而代之。如果继续使用unescape函数,则在获取中文参数时会导致获致              到的参数乱码，因此下面是改
      return decodeURI(r[2]);
    }
    return null;
}

//如果url中的参数是toutiaoForwardId与shareShortCode
//下面的方法是调用getQueryString获取Name
//http://127.0.0.1:8020/wx/admin/department/change_doctor_info.html?toutiaoForwardId=121f1a

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

//点击按钮，获取input的值，并通过url传递给下一个页面
$(‘#saveHospitalName‘).click(function(){
        var hospitalName = $(‘#hospitalName‘).val();
        console.log("医院名称" + hospitalName);
        window.location.href = "/wx/admin/department/change_doctor_info.html?hospitalName=" + hospitalName;
    });

//弹框，点击保存按钮，把弹框中的数据保存在当前页面
$(‘#saveDoctorName‘).click(function(){
        var doctorName = $(‘#doctorName‘).val();  //input的值
        $(‘#doctorNameShow‘).html(doctorName);  //当前页面值的保存位置
    })

//在一个div中动态添加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);
