如何将日期/文本传递给<input type="date"> ?

Question

I'm trying to set text in input date but nothing shows there.我正在尝试在输入日期中设置文本，但没有显示任何内容。 Is it something wrong with data type?数据类型有问题吗？

<!DOCTYPE html>
<html>
<body>

<table>
    <tr>
        <td id="invoice">
        2020-09-22
        </td>
    </tr>
</table>    

<select id="decisionList">
  <option></option>
  <option>Payment date</option>
</select>

<div id="choice">
</div>



<script>

document.addEventListener("change", function () {

  var decisionList = document.getElementById("decisionList");
  var selectedOptionIndex = decisionList.options[decisionList.selectedIndex].index;  
  
  var invoiceDate = document.getElementById("invoice");
  var invoiceDateText = invoiceDate.textContent;
  
  var finalChoice = document.getElementById("choice");

  switch(selectedOptionIndex) {
    
    case 0:
        finalChoice.innerHTML='<input type="date">'
    break;
   
    case 1:
        finalChoice.innerHTML='<input type="date" value="' + invoiceDateText + '">' //here is a problem
    break;

    default:
    
    finalChoice.innerHTML=''
    
  }
  
})

</script>

</body>
</html>

I also tried to create new Date based on text I'm passing:我还尝试根据我传递的文本创建新日期：

  var newDate = new Date(invoiceDateText);

but also doesn't work.但也不起作用。 As you can see I'm passing 2020-09-22 (from td) so where is the problem?如您所见，我正在通过 2020-09-22（来自 td）那么问题出在哪里？

Answer 1

The variable invoiceDateText contains white spaces and therefore is not parsed correctly.变量 invoiceDateText 包含空格，因此无法正确解析。

You can update that part to the following.您可以将该部分更新为以下内容。

 var invoiceDateText = invoiceDate.textContent.trim();

Answer 2

日期应该是一个字符串，格式为YYYY-MM-DD
