bootstrap 切换和 if 语句

bootstrap toggle and if statements

我正在尝试使用 bootstrap 创建 3 个切换,我添加了一些 if 语句,其中一些有效但其余的无效

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">

<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>

if 语句清晰易懂我的观点

有什么建议吗?

谢谢

当我尝试 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。在深入了解插件的文档后,我遇到了这个问题 #31。基本上,当您调用 .bootstrapToggle() 方法时,会触发 change 事件。但是在您的代码中,您有 change 调用 .bootstrapToggle() 的事件处理程序——所以您基本上是一遍又一遍地递归地触发 change() 事件——这会产生不需要的行为。

使用 one of the commenters' solutions,您可以:

$(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,我在围绕 input 元素创建的包装器上附加了一个 click 事件处理程序(因此我使用 event delegation)并使用它进行更改.
