Question

我在这里的代码中看不出有什么问题。如果输入'new horizon gurukul'，我希望它去NHGSignin.php。在单击Next按钮时，它应该重定向我，但它没有。我不明白为什么？提前谢谢！

这是我的代码：

var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();

function displaySignInError() {
  switch (schoolName) {
    case 'new horizon gurukul':
      document.getElementById("schoolName").action = 'NHGLogin.php';
      break;
    default:
      console.log('ajlsdfba');
  }
}

Answer 1

从你的回答中我猜你正试图改变表格的动作。

当你这样做时：

var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();

在函数外部，只有在呈现html时才会获得schoolName，如果你想在用户点击按钮时获取schoolName，你应该这样做：

function displaySignInError() {
  var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();
  switch (schoolName) {
    case 'new horizon gurukul':
      document.getElementById("schoolName").action = 'NHGLogin.php';
      break;
    default:
      console.log('ajlsdfba');
  }
}

检查下面的更新代码段。

function displaySignInError() {
  var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();
  switch (schoolName) {
    case 'new horizon gurukul':
      document.getElementById("schoolName").action = 'NHGLogin.php';
      break;
    default:
      console.log('ajlsdfba');
  }
}

Answer 2

而不是

document.getElementById("schoolName").action = 'NHGLogin.php';

用这个：

window.location = "NHGLogin.php";

如何在点击提交时重定向我的页面？
