这是我的代码，它不起作用，没有任何警报出现，并且似乎 javascript 不起作用。任何帮助将不胜感激。

function nameCheck()
{

   {
    return true;
   }

我认为这可能与脚本有关，但我不确定。

在第 11 行，您错过了一个).

if(input.firstName.value.length >= 2 && input.lastName.value.length >=2 &&
     input.firstName.value.match(/^[A-Za-z]+$/) && input.lastName.value.match(/     ^[A-Za-z]+$/) )  // <----- HERE

在第 22 行，你也错过了)

在功能ValidateForm 

function ValidateForm()
{
  if(nameCheck() == false)
  {
   alert("Invalid first or last name");
   input.firstName.focus();
  }

  if(emailCheck() == false)
  {
   alert("Invalid email address");
   input.email.focus();
  }

  if(phoneCheck() == false)
  {
   alert("Invalid phone number");
   input.phone.focus();
  }
}
