我正在尝试使用引导程序创建 3 个切换,并添加了一些 if 语句,其中一些有效,但其余无效

这是我的完整代码

<html>
  <head>
    <title>Bootstrap Form Helpers Basic Template</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">

  </head>
  <body>
    <h1>Hello, world!</h1>

<input id="toggle-email" checked type="checkbox" data-toggle="toggle" data-on="<i class='glyphicon glyphicon-ok'></i> Email On" data-off="<i class='glyphicon glyphicon-remove'></i> Email OFF" data-onstyle="success" data-offstyle="danger" data-width="150">

<input id="toggle-both" type="checkbox" data-toggle="toggle" data-on="<i class='glyphicon glyphicon-ok'></i> Email & Phone On" data-off="<i class='glyphicon glyphicon-remove'></i> Email & Phone OFF" data-onstyle="success" data-offstyle="danger" data-width="300">



<script>
	
	
	
	$(function() {
		
		
		$("#toggle-email").on("change", function () {
			if (this.checked) {
				$('#toggle-phone').bootstrapToggle('off');
				$('#toggle-both').bootstrapToggle('off');
			}
			else{
				$('#toggle-phone').bootstrapToggle('on');
				$('#toggle-both').bootstrapToggle('off');
			}
		})
		
		$("#toggle-phone").on("change", function () {
			if (this.checked) {
				$('#toggle-email').bootstrapToggle('off');
				$('#toggle-both').bootstrapToggle('off');
			}
			else{
				$('#toggle-email').bootstrapToggle('on');
				$('#toggle-both').bootstrapToggle('off');
			}
		})
		
		$("#toggle-both").on("change", function () {
			if (this.checked) {
				$('#toggle-email').bootstrapToggle('on');
				$('#toggle-phone').bootstrapToggle('on');
			}
			else{
				$('#toggle-email').bootstrapToggle('on');
				$('#toggle-phone').bootstrapToggle('off');
				
			}
		})
		
		
		
		
	});
	
	
</script>

<script src="https://gitcdn.github.io/bootstrap-toggle/2.2.2/js/bootstrap-toggle.min.js"></script>

  </body>
</html>

if 语句清晰易懂

有什么建议么?

谢谢你

当我试图运行你的代码片段时,我一直想知道为什么我会收到这个奇怪的错误。在浏览了插件的文档后,我遇到了这个问题#31。基本上,当您调用该方法change时会触发该事件。.bootstrapToggle()但是在你的代码中,你有change事件处理程序调用.bootstrapToggle()——所以你基本上是change()一遍又一遍地递归地触发事件——这会产生不希望的行为。

使用评论者的解决方案之一,您可以执行以下操作:

$(document).on('click', '[data-toggle=toggle]', function() {
  var input = $(this).find('input')[0]; 
  switch (input.id) {
    case 'toggle-email':
      $('#toggle-phone').bootstrapToggle(!input.checked ? 'on' : 'off');
      $('#toggle-both').bootstrapToggle('off');
      break;
    case 'toggle-phone':
      $('#toggle-email').bootstrapToggle(!input.checked ? 'on' : 'off');
      $('#toggle-both').bootstrapToggle('off');
      break;
    case 'toggle-both':
      $('#toggle-email').bootstrapToggle('on');
      $('#toggle-phone').bootstrapToggle(input.checked ? 'on' : 'off');
      break;
  }
});

<input id="toggle-email" checked type="checkbox" data-toggle="toggle" data-on="<i class='glyphicon glyphicon-ok'></i> Email On" data-off="<i class='glyphicon glyphicon-remove'></i> Email OFF" data-onstyle="success" data-offstyle="danger" data-width="150">


<input id="toggle-phone" type="checkbox" data-toggle="toggle" data-on="<i class='glyphicon glyphicon-ok'></i> Phone On" data-off="<i class='glyphicon glyphicon-remove'></i> Phone OFF" data-onstyle="success" data-offstyle="danger" data-width="150">

<input id="toggle-both" type="checkbox" data-toggle="toggle" data-on="<i class='glyphicon glyphicon-ok'></i> Email & Phone On" data-off="<i class='glyphicon glyphicon-remove'></i> Email & Phone OFF" data-onstyle="success" data-offstyle="danger" data-width="300">

基本上,我click在围绕input元素创建的包装器上附加了一个事件处理程序(因此我使用事件委托)并使用它来进行更改。
