在链接点击时显示/隐藏元素（表单）-通过Ajax提交表单

Question

我正在尝试使用jquery播种和隐藏表单。这是通过链接完成的...

我想隐藏所有带有data-action="edit"的链接，但是只显示链接旁边的表单，因为我在此站点上还有更多框。

我只想显示第一个框的形式（单击链接即可）

我还需要a（"box box-primary"）位于的类data-action="save"的div的ID。

$(document).ready(function() {
  $('a[data-action=edit').on('click', function() {
    $('div .box-tools').addClass('hide');
    $(this).next('div .spinner').removeClass('hide');
    $(this).next('dl.view-data').addClass('hide');
    $(this).next('form.form-data').removeClass('hide');
  });

  $('a[data-action=cancel').on('click', function() {
    $('div .box-tools').removeClass('hide');
    $('div .spinner').first().addClass('hide');
    $('dl.view-data').first().removeClass('hide');
    $('form.form-data').first().addClass('hide');
  });

  $('a[data-action=save').on('click', function() {
    alert($(this).closest('form.form-data').serialize());
  });
});

.box.box-primary {
  border-top-color: #00acd6;
}

.box {
  -webkit-border-radius: 0;
  -moz-border-radius: 0;
  border-radius: 0;
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
  -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
  box-shadow: 0 0 2px rgba(0, 0, 0, 0.25);
  border-top: 3px solid #dddddd;
}

.box {
  position: relative;
  background: #ffffff;
  border-top: 2px solid #c1c1c1;
  margin-bottom: 20px;
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  width: 100%;
  box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
}

.hide {
  visibility: hidden;
}

Answer 1

您需要阅读.next()的工作原理，

但这是您的代码的有效示例：

$(document).ready(function() {
  $('a[data-action=edit').on('click', function() {
    $(this).closest(".box-primary").find('dl.view-data, .box-tools').addClass('hide');
    $(this).closest(".box-primary").find('.spinner, form.form-data').removeClass('hide');
  });

  $('a[data-action=cancel').on('click', function() {
    $(this).closest(".box-primary").find('.box-tools, dl.view-data').removeClass('hide');
    $(this).closest(".box-primary").find('.spinner, form.form-data').addClass('hide');
  });

  $('a[data-action=save').on('click', function() {
    alert($(this).closest('form.form-data').serialize());
  });
});

示例您的edit按钮没有$(this).next('div .spinner')，因为如果您查看html，则a没有兄弟姐妹，因此next()不起作用在这里。

演示

$(document).ready(function() {
  $('a[data-action=edit').on('click', function() {
    $(this).closest(".box-primary").find('dl.view-data, .box-tools').addClass('hide');
    $(this).closest(".box-primary").find('.spinner, form.form-data').removeClass('hide');
  });

  $('a[data-action=cancel').on('click', function() {
    $(this).closest(".box-primary").find('.box-tools, dl.view-data').removeClass('hide');
    $(this).closest(".box-primary").find('.spinner, form.form-data').addClass('hide');
  });

  $('a[data-action=save').on('click', function() {
    alert($(this).closest('form.form-data').serialize());
  });
});

.box.box-primary {
  border-top-color: #00acd6;
}

.box {
  -webkit-border-radius: 0;
  -moz-border-radius: 0;
  border-radius: 0;
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
  -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
  box-shadow: 0 0 2px rgba(0, 0, 0, 0.25);
  border-top: 3px solid #dddddd;
}

.box {
  position: relative;
  background: #ffffff;
  border-top: 2px solid #c1c1c1;
  margin-bottom: 20px;
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  width: 100%;
  box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
}

.hide {
  visibility: hidden;
