引导开关单击事件未在表单向导中触发答案

【问题标题】：Bootstrap Switch Click Event Not Firing In Form Wizard引导开关单击事件未在表单向导中触发
【发布时间】：2016-03-18 14:36:33
【问题描述】：

我有一个表单向导，其中有一个复选框。我正在使用引导开关向用户显示切换按钮。每次用户单击按钮时，它应该显示 YES 或 NO（用于选中/取消选中）。但是，除非我执行以下操作之一，否则单击事件不起作用：

删除向导，引导开关按钮将按预期工作。
注释引导开关代码

$("[type='checkbox']").bootstrapSwitch();
使用委托添加点击事件

$('#UserForm').on('click', '#checkbox1', function () { console.log('你点击我'); });

$(document).ready(function() {
  //  $("[type='checkbox']").bootstrapSwitch();
  //comment out the above line code.
});

var form = $("#UserForm").show();

form.steps({
  headerTag: "h3",
  bodyTag: "fieldset",
  transitionEffect: "slideLeft",
  onStepChanging: function(event, currentIndex, newIndex) {
    // Allways allow previous action even if the current form is not valid!
    if (currentIndex > newIndex) {
      return true;
    }
    // Forbid next action on "Warning" step if the user is to young
    if (newIndex === 3 && Number($("#age-2").val()) < 18) {
      return false;
    }
    // Needed in some cases if the user went back (clean up)
    if (currentIndex < newIndex) {
      // To remove error styles
      form.find(".body:eq(" + newIndex + ") label.error").remove();
      form.find(".body:eq(" + newIndex + ") .error").removeClass("error");
    }
    form.validate().settings.ignore = ":disabled,:hidden";
    /// return form.valid();
    return ValidForm(this, currentIndex);
  },
  onStepChanged: function(event, currentIndex, priorIndex) {
    // Used to skip the "Warning" step if the user is old enough.
    if (currentIndex === 2 && Number($("#age-2").val()) >= 18) {
      form.steps("next");
    }
    // Used to skip the "Warning" step if the user is old enough and wants to the previous step.
    if (currentIndex === 2 && priorIndex === 3) {
      form.steps("previous");
    }
  },
  onFinishing: function(event, currentIndex) {
    return ValidForm(this, currentIndex);
    //  return form.valid();
  },
  onFinished: function(event, currentIndex) {
    submitForm();
  }
}).validate({
  errorPlacement: function errorPlacement(error, element) {
    element.before(error);
  },
  rules: {
    confirm: {
      equalTo: "#password-2"
    }
  }
});

如果我删除下面的代码，点击事件触发没有问题。

$("[type='checkbox']").bootstrapSwitch();

【问题讨论】：

你检查你的控制台了吗？我收到此错误：TypeError: form.steps(...).validate is not a function
我的控制台上没有错误。如果您没有 jquery 验证参考，您可能会收到此错误。我更新了文件并添加了对 jquery validate 的引用。

【解决方案1】：

好的，我终于找到了一些解决方案。

而不是

$('#UserForm').on('click', '#checkbox1', function () { console.log('you click me'); });

添加此代码，您将在更改时收到一个事件。

$('#checkbox1').on('switchChange.bootstrapSwitch', function (e, state) {

            if(state){
                        alert("Checked");
                        // Your Code Here

            }else{
                        alert("Not Checked");
                        // Your Code Here

            }

        });
