Javascript onclick提交按鈕問題
[英]Javascript onclick submit button issues
問題描述
我正在通過表單驗證用戶信息。 我做了一個簡單的用戶信息表格，但無法獲取提交按鈕來調用頭部的javascript功能。 我不知道我的結構是否不正確。 我看了一下頭上的腳本，但找不到問題。 有人可以通過提交按鈕幫助我找到問題嗎？ 下面，為清楚起見，我粘貼了整個網頁。

var gender = document.getElementById("gender").value;
var age = document.myform.age.option[document.myform.age.selectedIndex].value;
var state = document.myform.state.option[document.myform.state.selectedIndex].value;
var checkboxes = document.getElementsByName('box');
var selected = [];
for (var i=0; i<checkboxes.length; i++) {
if (checkboxes[i].checked) {
selected.push(checkboxes[i].value);
}
}

你有我錯字錯誤定義函數getResults
只需修復函數定義，我想一切都會好的
問候
是的，您還有其他幾個錯誤：
- 設置表單字段名稱
- 通過各自的名稱訪問它們。
你可以在這里查看我的修復

您將function fucntion拼為fucntion 。 希望能解決它。

將type =“ button”更改為type =“ submit”。
如果啟用了Javascript，則使用onclick事件替換提交按鈕
[英]Replace submit button with onclick event if Javascript enabled
