所以我有这个功能，创造了月份的textareas。因此，如果它是三月，那么就是四月份的31 textareas，然后是30 textareas等等。当用户单击一个textarea然后单击提交按钮时，应将textarea的值提交给db。因此，如果用户标记为2018-02-04，则应将该日期插入到数据库中。但是，我现在的问题是，提交的唯一值是每个月的最后一个日期。不知道为什么，也不知道如何解决它。认为它可能是ID的东西。
功能：
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("textarea");
textarea.setAttribute("placeholder", day1 );
//textarea.setAttribute("id", some_value); does not work
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 );
}
HTML：
<form class="" action="index.php" method="post">
<table id="table" cellspacing="0" cellpadding="0" border-collapse="collapse";>
<br>
<input id="btn" type="submit" name="" value="Send">
</form>
PHP：
<?php
include ("connection.php");
$day = mysqli_real_escape_string($conn, $_REQUEST['day']);
$stmt = "INSERT INTO table (day) VALUES('$day')";
if(empty($day)){
$_SESSION['error'] = "Please fill in required fields";
header('Location: index.php', true, 303);
exit();
} else {
if (mysqli_query($conn, $stmt)) {
header('Location: index.php', true, 303);
exit;
}else {
$error= "Error: " .mysqli_error($conn);
echo "$error";
}
}
?>
所有帮助都是适当的！ :)

首先，我建议您始终检查输出...这就是您的javascript创建的内容。
$("#other").select2({
tags: true,
data: data,
escapeMarkup: function(markup) {
return markup;
},
createTag: function(params) {
var obj = {
id: 'new_' + params.term,
text: '<div style="font-size: 1.2em; color:blue">' + params.term + '</div><div><b>Select2</b> supports custom themes using the theme option so you can style Select2 to match the rest of your application.</div>',
title: params.term,
isNew : true
};
return obj;
}
}).on('select2:select', function (e) {
if(e.params.data.isNew) {
data.push({id: e.params.data.id, text: '<div style="font-size: 1.2em; color:blue">' + e.params.data.text + '</div><div><b>Select2</b> supports custom themes using the theme option so you can style Select2 to match the rest of your application.</div>', title: e.params.data.text});
}
});
正如您所看到的，您将始终获得最后一个textarea的“日期”值，因为您的表单没有“day”属性的唯一值
您应该为每个textarea添加一个带有提交按钮的表单，或者完全重写您的代码..
快速解决方案：

<textarea placeholder="03" name="day" day="2018-02-03">2018-02-03</textarea>
<textarea placeholder="04" name="day" day="2018-02-04">2018-02-04</textarea>
<textarea placeholder="05" name="day" day="2018-02-05">2018-02-05</textarea>
<textarea placeholder="06" name="day" day="2018-02-06">2018-02-06</textarea>

<textarea placeholder="14" name="day" day="2018-02-14">2018-02-14</textarea>

<textarea placeholder="19" name="day" day="2018-02-19">2018-02-19</textarea>
<textarea placeholder="20" name="day" day="2018-02-20">2018-02-20</textarea>
<textarea placeholder="21" name="day" day="2018-02-21">2018-02-21</textarea>
<textarea placeholder="22" name="day" day="2018-02-22">2018-02-22</textarea>
<textarea placeholder="23" name="day" day="2018-02-23">2018-02-23</textarea>
<textarea placeholder="24" name="day" day="2018-02-24">2018-02-24</textarea>
<textarea placeholder="25" name="day" day="2018-02-25">2018-02-25</textarea>
<textarea placeholder="26" name="day" day="2018-02-26">2018-02-26</textarea>
<textarea placeholder="27" name="day" day="2018-02-27">2018-02-27</textarea>
<textarea placeholder="28" name="day" day="2018-02-28">2018-02-28</textarea>
</tr>
<tr></tr>
<tr></tr>
<tr></tr>
</table>
</form>
js，从textarea中删除“名称”。在drawTable中添加事件监听器“onchange”
<form class="" action="index.php" method="post">
<input id="day" type="hidden" name="day" value="">
<table id="table" cellspacing="0" cellpadding="0" border-collapse="collapse";>
<br>
<input id="btn" type="submit" name="" value="Send">
</form>
PHP文件应该是好的
