如果在引导模式上单击“是”按钮，则仅选中复选框答案

【问题标题】：Check only the checkbox if Yes button was clicked on bootstrap modal如果在引导模式上单击“是”按钮，则仅选中复选框

【问题描述】：

如果我想选中一个复选框，那么如果在引导模式上单击“YES”按钮，则必须选中该复选框，如果单击“NO”按钮则保持取消选中状态。

另一方面也是如此，如果要取消选中一个复选框，那么如果在引导模式上单击“是”按钮，则该复选框必须取消选中并保持检查是否单击了“否”按钮。

【解决方案1】：

您可以保存单击的复选框并返回false 以防止其更改状态。然后根据对话框中按下的按钮来勾选或取消勾选：

var clickedCheckox;

$('.status').click(function(){
	clickedCheckbox = $(this);
  if(clickedCheckbox.is(':checked')) {
    $('#activate').modal('show');
  } else {
    $('#deactivate').modal('show');
  }

  return false;
});

$("#activateBtn").click(function() {
	clickedCheckbox.prop("checked", true);
});

$("#deactivateBtn").click(function() {
	clickedCheckbox.prop("checked", false);
});

【解决方案2】：

如果您不希望复选框在单击时更改其状态，则应使用.preventDefault()

// variable will hold a checkbox:
var status_box = null;

$('.status').click(function(event){
  event.preventDefault();
  // set which checkbox has been clicked:
  status_box = this;
  if($(this).is(':checked')) {
    $('#activate').modal('show');
  } else {
    $('#deactivate').modal('show');
  }
});

然后为modal里面的按钮注册click事件处理程序：

$('.btn-yes').click(function(){
    $(status_box).prop('checked', !status_box.checked);
});

JSFiddle Demo

或者，您可以通过将单击的复选框存储在'.btn-yes' 按钮的data-* attribute 中来摆脱 status_box 变量：

$('.status').click(function(event){
  event.preventDefault();
  $('.btn-yes').data('status_box', this);
  $(this.checked ? '#activate' : '#deactivate').modal('show');
});

$('.btn-yes').click(function(){
  var box = $(this).data('status_box');
  box.checked = !box.checked;
});
