我有这个功能可以创建按钮,它取决于它的月份。如果是二月,那么28个按钮,三月,那么31个按钮等等。然后我有这个创造手风琴的功能。但是,我的问题是我无法连接它们。我希望javascript创建的按钮可以作为手风琴使用。不太确定如何做到这一点。所以我的问题是如何将我的函数用于根据月份创建的按钮的手风琴? 下面的代码片段和按钮的jsfiddle:https://jsfiddle.net/20psfauc/6/
按钮的功能和html:
var showDate = new Date();
var months = ["Januari", "Februari", "March", "April", "May", "June",
"July", "Augusti", "September", "October", "November", "December"];
var weeks = ["Sunday","Monday","Tuseday","Wednesday","Thursday","Friday","Saturday"];
function drawTable(forDate) {
var daysInMonth = new Date(forDate.getFullYear(),forDate.getMonth()+1,0).getDate();
var cellsToDraw = daysInMonth;
var newdate = forDate.getFullYear() +"-"+ ("0"+ (forDate.getMonth() + 1)).slice(-2);
var table = document.getElementById("table");
table.innerHTML = "";
for (var r = 0; r < (daysInMonth / 7); r++) {
var newRow = document.createElement("tr");
table.appendChild(newRow);
for (var c = 0; c < 31 && cellsToDraw > 0; c++) {
var day1 = ("0" + (c + 1)).slice(-2);
var textarea = document.createElement('button')
textarea.setAttribute("placeholder", day1 );
textarea.setAttribute("class", "row");
//textarea.setAttribute("id", some_value);
newRow.appendChild(textarea);
textarea.setAttribute("name", "day");
textarea.setAttribute("day", newdate + "-" + day1 );
textarea.innerHTML = newdate + "-" + day1;
cellsToDraw--;
}
}
}
window.onload = function() {
document.getElementById("displayingMonth").innerHTML = months[showDate.getMonth()];
drawTable(showDate );
};
function next() {
if (showDate.getMonth() == 11) {
showDate.setMonth( 0 );
showDate.setFullYear( showDate.getFullYear()+1 );
} else {
showDate.setMonth( showDate.getMonth()+1 );
}
document.getElementById("displayingMonth").innerHTML = months[showDate.getMonth()];
drawTable( showDate );
}
function daysInMonth(month, year) {
var days;
switch (month) {
case 1: // Feb, our problem child
var leapYear = ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
days = leapYear ? 29 : 28;
break;
case 3:
case 5:
case 8:
case 10:
days = 30;
break;
default:
days = 31;
}
return days;
}

我不确定我是否完全理解你想要在页面上看到什么 - 我尝试将你的代码放在一个jsfiddle中我没有看到根据月份创建的任何按钮,它似乎遗漏了一些代码。
但是 - 如果您希望您的手风琴功能对于为每月的每一天创建的按钮有用,他们需要具有与您当前使用手风琴功能的其他按钮相同的结构。他们需要classname&#34; row&#34;,因为那样做手风琴工作的事件监听器如何附加。由于您的函数调用this.nextElementSibling
,因此每个按钮还需要一个兄弟元素。
更新
感谢小提琴!
因此,在您的代码中,您需要创建按钮并在其上设置属性,而不是要创建&#34;面板&#34;单击日期按钮时手风琴会上升或下降的元素?我认为重命名&#34; textarea&#34;更有意义。到&#34;按钮&#34;并创建一个单独的textarea元素:
var button = document.createElement("button");
var textarea = document.createElement("div");
textarea.setAttribute("class", "panel");
newRow.appendChild(textarea);
然后你可以在按钮上添加一个事件监听器来修改&#34;面板&#34;。这对我来说不是100%的工作,而是玩弄它:
button.addEventListener("click", function() {
var panel = this.nextElementSibling;
if (panel.style.maxHeight) {
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = "50px";
}
});
在css中,我将height: 100px;
添加到.panel {}
块。
不过,你仍然需要弄清楚如何在日期之下获得黄色块。我希望这有帮助!
另一个更新: 如果你把按钮和textarea放在一个父div中,它们会在另一个下面排成一行,虽然这确实意味着每个按钮都排在另一个之下:
var button = document.createElement("button");
var textarea = document.createElement("div");
var container = document.createElement("div");
button.setAttribute("placeholder", day1 );
button.setAttribute("class", "row");
textarea.setAttribute("class", "panel");
container.setAttribute("class", "container");
newRow.appendChild(container);
container.appendChild(button);
container.appendChild(textarea);
作为旁注,我认为通过查看您的代码,您会尝试创建一个表格,其中表格中的每一行代表一周。现在,所有按钮都在第一行结束。如果检查表,可以看到这个。要解决此问题,您需要将此处的计数器更改为小于7而不是31:for (var c = 0; c < 7 && cellsToDraw > 0; c++) {
当你有它工作时,你可能想要考虑从表中切换并在div中重新创建它。通常情况下,如果我们使用的是表格,我们也会使用<td>
,但我不确定这是否可行,因为您希望在每个td
下面放置文字。有一个带有按钮和div的桌子感觉有点不对劲。

我结合了这个功能并做了一些小的调整。这是你的意思吗?

编辑:当用户点击按钮时添加了一个基本表单 - 正如您在评论时要求的那样。
EDIT2:点击另一个按钮时切换。
