Question

您好我正在提交调查问卷并尝试使用onSubmit获取结果，但它无效

的JavaScript

function results_addition(){
  var results = total + Details + formElement;

  if(results<30){
    document.submit_form.choice1.value="Low Risk";
  }else{
    if(results>50){
      document.submit_form.choice1.value="High Risk";
    }else{
      document.submit_form.choice1.value="Medium Risk";
    }
  }
}

HTML

<form name="choice1" onSubmit="results_addition()">
<input type="submit" value="Submit">

Answer 1

请尝试onsubmit代替onSubmit，然后添加结束</form>代码

Answer 2

<html>
<body>

<p>When you submit the form, a function is triggered which alerts some text.</p>

<form name="choice1" onSubmit="results_addition()">
<input type="submit" value="Submit">
</form>

<script>
function results_addition(){
alert("hello")
}
</script>

</body>
</html>

我尝试了相同的表单并且正在运行我认为您还没有正确关闭表单。

Answer 3

更改

<form name="choice1" onSubmit="results_addition()">

到

<form name="choice1" onSubmit="return results_addition()">
在函数末尾添加以下内容

return false;

在尝试获得结果时，onSubmit不起作用
