Question

我正在尝试拦截并处理引导程序复选框中的更改，并且我添加了一个“onchange＆amp; fn;事件。不幸的是，我没有成功。目前，我有一个按钮，可以更改复选框的状态，这是有效的。

任何提示都会非常感激。

Answer 1

文档说使用jQuery change。

<强>演示：

＆＃13;

$('#chk1').change(function() {
  alert($(this).prop('checked'))
})

＆＃13;

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/css/bootstrap.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/js/bootstrap.min.js"></script>
<link href="https://gitcdn.github.io/bootstrap-toggle/2.2.2/css/bootstrap-toggle.min.css" rel="stylesheet">
<script src="https://gitcdn.github.io/bootstrap-toggle/2.2.2/js/bootstrap-toggle.min.js"></script>

<input id="chk1" type="checkbox" checked data-toggle="toggle">

＆＃13;

Answer 2

它适用于所有复选框，如下例所示：

＆＃13;

$('input:checkbox').change(function() {
  $('#console-event').html('Toggle: ' + $(this).prop('checked'));
  console.log("Change event: " + this.id);
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/js/bootstrap.min.js"></script>
<link href="https://gitcdn.github.io/bootstrap-toggle/2.2.2/css/bootstrap-toggle.min.css" rel="stylesheet">
<script src="https://gitcdn.github.io/bootstrap-toggle/2.2.2/js/bootstrap-toggle.min.js"></script>
<input id="chk1" type="checkbox" data-toggle="toggle">                
<input id="chk2" type="checkbox" data-toggle="toggle">
<input id="chk3" type="checkbox" data-toggle="toggle">
<input id="chk4" type="checkbox" data-toggle="toggle">
<div id="console-event"></div>

＆＃13;

修改

添加如下代码：

<script> $(function() { $('input:checkbox').change(function() { $('#console-event').html('Toggle: ' + $(this).prop('checked')) }) }) </script>

Answer 3

<input id="chk1" type="checkbox" data-toggle="toggle" onclick="fonctionTest()"> 

function fonctionTest(){
  if (document.getElementById('chk1').checked) 
  {
      alert("Checked")
  } else 
  {
      alert("Not Checked")
  }
}
