Question

我有一个如下所示的PHP。该页面有一些javascript验证。我正在使用网站found here上找到的gen_validatorv4.js。

此脚本完美无缺，但无法对日期时间字段进行比较验证。为此，我从另一个stackoverflow帖子found here获得了帮助。感谢@RobG给了我一个工作日期时间比较验证脚本。

我的问题是，当我将两个脚本添加到页面时，只有一个工作，禁用另一个。如何在提交表单时获取两组代码？

我的完整代码ii如下所示，感谢提前帮助和节日祝福所有人！莱恩

Answer 1

您需要CUSTOM验证程序，因为无法直接比较这两个值

这未经过测试 - 我认为我们需要创建日期或访问datpicker getTime（）值而不是输入字段中的字符串值：

frmvalidator.setAddnlValidationFunction("DoCustomValidation");

function DoCustomValidation() {
  var form = document.forms["myform"];
  if (form.collectdatetime.value >= form.deliverdatetime.value) { 
    alert('Collection time must be after deliver time'); 
    return false; 
  } 
  return true;
}

javascript表单验证 - 在表单提交上调用两个脚本
