Question

我不明白我在这里做错了什么....尝试了几乎所有的表格仍然没有经过验证提交。我不知道造成问题的原因是这里过去4个小时一直在研究这个问题，每次我点击提交按钮就会直接进入提交成功页面......有人可以帮我这个吗？

<script type ="text/javascript">
function validate(){
if(document.orderForm.firstName.value=="" ){
document.getElementById('errors').innerHTML = "Please Enter a First Name";
document.orderForm.fistName.focus();
return (false);
}
if(document.orderForm.lastName.value == "" ){
document.getElementById('errors').innerHTML = "Please Enter a Last Name";
document.orderForm.lastName.focus();
return (false);
}
if(document.orderForm.address.value == "" ){
document.getElementById('errors').innerHTML = "Please Enter a address");
document.orderForm.address.focus();
return (false);
}
if(document.orderForm.city.value == "" ){
document.getElementById('errors').innerHTML = "Please Enter a City");
document.orderForm.city.focus();
return (false);
}
if(document.orderForm.postalCode.value == "" ||
document.orderForm.postalCode.value.length != 6 ){
document.getElementById('errors').innerHTML = "Please Enter a correct PostalCode");
document.orderForm.postalCode.focus(); 
return (false);
}
if(document.orderForm.province.value == "Select" ){
document.getElementById('errors').innerHTML = "Please Select your province")
return (false);
}
if(document.orderForm.widget1qty.value == "0" || document.orderForm.widget1qty.value == "" &&
document.orderForm.widget2qty.value == "0" || document.orderForm.widget2qty.value == "" &&
document.orderForm.widget2qty.value == "0" || document.orderForm.widget2qty.value == "" ){
document.getElementById('errors').innerHTML = "Please Select at least one item")
return (false);
}
else
{
return(true);
}
}
</script>

请使用以下代码。它工作正常。

function validate() {
  if (document.orderForm.firstName.value=="" ) {
    document.getElementById("errors").innerHTML = `Please enter first name`;
    document.getElementById("firstName").focus();
    return (false);
  }
}


<form name="orderForm"  onSubmit="return validate();">
  <input type="text" id="firstName" />
  <input type="submit" id="btnSubmit" value="submit" />
  <div id="errors"></div>
</form>
