What I understand from your question is - "Before posting the form, you'd like to check if the DOB field has a date that must not be greater than today's date.". If this is correct, then try this, Hope this help -
我从您的问题中了解到 - “在发布表单之前，您想检查 DOB 字段的日期是否不得大于今天的日期。”。如果这是正确的，那么试试这个，希望这有助于 -
<script type="text/javascript">
function checkDOB() {
var dateString = document.getElementById('id_dateOfBirth').value;
var myDate = new Date(dateString);
var today = new Date();
if ( myDate > today ) {
$('#id_dateOfBirth').after('<p>You cannot enter a date in the future!.</p>');
return false;
}
return true;
}
</script>

If you can use php do:
<input type="date" name="date1" max=<?php echo date('Y-m-d'); >
如果您可以使用 php，请执行以下操作：
<input type="date" name="date1" max=<?php echo date('Y-m-d'); >
if only js:
如果只有js：
document.getElementById("id_dateOfBirth").setAttribute("max", today);
where today is eg 2017-03-10 to get this date use eg :
今天是例如 2017-03-10 获得这个日期使用例如：
new Date().toJSON().split('T')[0]
