如果/ Else语句不正常（Else语句特别胜出）

时间：2016-08-23 22:21:31

标签： javascript jquery

我正在尝试创建一个脚本，根据是否选择了某个选项来管理内容的可见性。我遇到的问题是我的if / else语句无法正常运行。

当选中最后一个.provider-info单选按钮时显示div .radial-container（即＆＃34;我想保留我的号码＆＃34;）。

当从父容器中删除类slideUp时，它应该.select，但它不会。

我进行了一些实验，并且能够通过不同的代码获得我正在寻找的功能：

 $(function() {
  $('.radial-container').on('click', function() {
    $(this).addClass('select').siblings().removeClass('select');
    if($('.radial-container').last().hasClass('select')) {
      $(this).children('.provider-info').slideDown(300);
    } else {
      $('.provider-info').slideUp(300);
    }
  })
})

但上述细分市场的问题在于它仅适用于Unlimited Line 2.无限制的Line 1基本上失去了功能。

如何修复此代码以使if / else语句正常运行？我只希望在选择第二个单选按钮时可以看到div .provider-info。

谢谢，

你想用吗？ $（this）。孩子们在else块中也是？

 $(this).children('.provider-info').slideDown(300);
} else {
  $(this).children('.provider-info').slideUp(300);

答案 1 :(得分：0)

这应该做的工作：

$('.radial-container').on('click', function() {
    $(this).addClass('select')
           .siblings('.radial-container')
           .removeClass('select')
           .find('.provider-info')
           .slideUp(300);
    $('.provider-info', this).slideDown(300);
});

修正演示：

＆＃13;
＆＃13; 
$(function() {
    $('.radial-container').on('click', function() {
        $(this).addClass('select')
               .siblings('.radial-container')
               .removeClass('select')
               .find('.provider-info')
               .slideUp(300);
        $('.provider-info', this).slideDown(300);
    });
});
