推荐答案

假设您要检查文本框的输入是有效日期，则可以请参阅以下文章
JavaScript日期验证 [

Assuming that you want to check the input to textbox is a valid date, you can refer the below article
JavaScript Date Validation[^]

创建一个javascript函数，并在表单提交事件中调用它.
试试这个:
Javascript:

Create a javascript function and call that on form submit event.
Try this:
Javascript:

<script type="text/javascript">
function checkdate(input){
    var validformat=/^\d{2}\/\d{2}\/\d{4}

/基本检查格式有效性 var returnval = false 如果(！validformat.test(input.value)) alert(" ) 其他 {// 详细检查有效日期范围 var monthfield = input.value.split(" )[ 0 ] var dayfield = input.value.split(" )[ 1 ] var yearfield = input.value.split(" )[ 2 ] var dayobj = 新 日期(年份， monthfield-1，dayfield) 如果((dayobj.getMonth()+ 1！= monthfield)||(dayobj.getDate()！= dayfield)|||(dayobj.getFullYear()！=年)) alert(" ) 其他 returnval = true } 如果(returnval == < false ) input.select() 返回 returnval } </script>

/ //Basic check for format validity var returnval=false if (!validformat.test(input.value)) alert("Invalid Date Format. Please correct and submit again.") else{ //Detailed check for valid date ranges var monthfield=input.value.split("/")[0] var dayfield=input.value.split("/")[1] var yearfield=input.value.split("/")[2] var dayobj = new Date(yearfield, monthfield-1, dayfield) if ((dayobj.getMonth()+1!=monthfield)||(dayobj.getDate()!=dayfield)||(dayobj.getFullYear()!=yearfield)) alert("Invalid Day, Month, or Year range detected. Please correct and submit again.") else returnval=true } if (returnval==false) input.select() return returnval } </script>

HTML:

HTML:

<form onSubmit="return checkdate(this.mydate)">
<input type="text" name="mydate" />
<input type="submit" value="submit" /><br />
Valid date format: mm/dd/yyyy<br />
<input type="submit" value="submit" />
</form>
