推荐答案

您好，

您可以使用PreSaveAction验证结束日期必须大于7天的开始日期，如下所示：

You could use PreSaveAction to validate the end date must greater than start date with 7 days like this:

<script type="text/javascript" src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script type="text/javascript">

function PreSaveAction()
{
  var start=new Date(

（" input [title ='start date'] "）VAL（））。

var end = new Date（

("input[title='start date']").val()); var end=new Date(

（" input [title ='end date']"）。val（））;
var diff = end-start;
var diffdays = parseInt（diff / 1000/60/60/24）;
if（diffdays> 7）
{
return true;
}
其他
{
提醒（"请确保结束日期比开始日期至少大7天"）;
返回false;
}
}

< / script>

("input[title='end date']").val()); var diff=end-start; var diffdays=parseInt(diff / 1000 / 60 / 60 / 24); if(diffdays > 7) { return true; } else { alert("please make sure the end date is at least 7 days greater than start date"); return false; } } </script>

将代码添加到内容编辑器Web部件中以使列表新表单生效，单击保存按钮时会弹出警告消息并阻止保存数据：

Add the code into the Content Editor Web Part for the list new form to make it work, when clicking saving button it will pop up the warning message and prevent saving data:

谢谢
