如何在javascript函数中使用html标记建立列表

我已经编写了用javascript显示日期（月、日、日、年）的代码，并将其放在ul中

我的问题是如何在javascript函数中建立一个带有html标记的li（这样我就可以在函数中放置分隔符），因为现在如果我想执行以下操作

var output = "<li>" + month_full[monthFull] + "<br/>" +  weekDay[day] + "</li>";
return output;

var output=“
”+月整[月整]+”
“+工作日[日]+”
”；
返回输出；

它将准确地输出其显示方式->

你可以水平滚动我的月份。现在，我想这样构建它：

要查看我的JSFIDLE以查看我现在拥有的内容：

我的javascript代码如下所示：

<script>
// Get today's current date.
var now = new Date();
console.log(now);

// Calculates the number of the week
var weekNumber = ((now.getDate()<10) ? "0" : "")+ now.getDate();
console.log("The current week number is: " + weekNumber);

// Array list of months.
var month_full = new Array(12);
month_full[0] = "January";
month_full[1] = "February";
month_full[2] = "March";
month_full[3] = "April";
month_full[4] = "May";
month_full[5] = "June";
month_full[6] = "July";
month_full[7] = "August";
month_full[8] = "September";
month_full[9] = "October";
month_full[10] = "November";
month_full[11] = "December";
//console.log(month[3]);

var weekDay = new Array(7);
weekDay[0]=  "Su";
weekDay[1] = "Mo";
weekDay[2] = "Tu";
weekDay[3] = "We";
weekDay[4] = "Th";
weekDay[5] = "Fr";
weekDay[6] = "Sa";

function weekNr_Month(date){
    var month = date.getUTCMonth(); 
    return month[month];
}

function formatDate(date) {
    var month = date.getUTCMonth() +1;
    var dayNumber = date.getUTCDate();
    var year = date.getUTCFullYear();
    var day = date.getUTCDay();
    var monthFull = date.getUTCMonth(); 

    return month_full[monthFull] + " " +  weekDay[day] + ": " + dayNumber + "-" + month + "-" + year + ";  ";
}
console.log(formatDate(new Date()));

var today

function addListItem(){
    var createListItem = document.createElement("li");
    var outputListItem = document.createTextNode(today);

    createListItem.appendChild(outputListItem);
    var createUl = document.getElementsByTagName("ul");
    createUl[0].appendChild(createListItem);
}

// loop starting from may up untill for months from the set date
for (var i = 1; i < 122; i++){
    today = formatDate(new Date(2015, 05, i));
    //document.write(today + "<br />");
    addListItem();
}

document.getElementById('timeline').
getElementsByTagName('li')[(new Date()).getDate() + 1].className += ' currentDate';

</script>

//获取今天的当前日期。
var now=新日期（）；
console.log（现在）；
//计算周数
var weekNumber=（（now.getDate（）这是因为您正在创建一个文本节点而不是html内容。
试试这个：

var createListItem = document.createElement("li");
    createListItem.innerHTML = today;

标记后添加列表。请注意，您可能不希望
中已经存在的
ul
，这可能会打乱您的样式：-）
