bootstrap模式中的Twitter共享按钮在firefox上不起作用

Twitter share button inside bootstrap modal not working on firefox

本文关键字：firefox 不起作用 按钮 共享 模式 Twitter bootstrap      更新时间：2023-09-26

我有两个twitter共享按钮，一个在主体上，另一个在引导模式中。

两个"共享"按钮都适用于chrome，但不适用于Firefox。在Firefox上，第一个外部模式的共享按钮正在工作，但当我打开模式时，我看不到共享按钮。

是虫子吗？这个问题有什么解决办法吗？

这是我的代码

      </div>
    </div>
</body>
</html>

这看起来像一个bug，因为小部件按钮隐藏在Firefox和Twitter提供的css中。然而，我已经找到了解决方法——基本上你可以自己创建丢失的按钮。

1） 更改modal-bodydiv的内容如下：

<div class="modal-body">
    <a href="https://twitter.com/intent/tweet">
        <i class="btn-icon"></i>
        <span class="btn-text">Tweet</span>
    </a>
</div>

2） 将以下样式添加到您的页面：

.modal-body a .btn-icon{
    position: relative;
    width:60px;
    height: 20px;
    padding: 1px 10px 1px 7px;
    font-weight: 500;
    color: #fff;
    cursor: pointer;
    background-color: #1b95e0;
    border-radius: 3px;
    box-sizing: border-box;
    background-image:url("data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%2072%2072%22%3E%3Cpath%20fill%3D%22none%22%20d%3D%22M0%200h72v72H0z%22%2F%3E%3Cpath%20class%3D%22icon%22%20fill%3D%22%23fff%22%20d%3D%22M68.812%2015.14c-2.348%201.04-4.87%201.744-7.52%202.06%202.704-1.62%204.78-4.186%205.757-7.243-2.53%201.5-5.33%202.592-8.314%203.176C56.35%2010.59%2052.948%209%2049.182%209c-7.23%200-13.092%205.86-13.092%2013.093%200%201.026.118%202.02.338%202.98C25.543%2024.527%2015.9%2019.318%209.44%2011.396c-1.125%201.936-1.77%204.184-1.77%206.58%200%204.543%202.312%208.552%205.824%2010.9-2.146-.07-4.165-.658-5.93-1.64-.002.056-.002.11-.002.163%200%206.345%204.513%2011.638%2010.504%2012.84-1.1.298-2.256.457-3.45.457-.845%200-1.666-.078-2.464-.23%201.667%205.2%206.5%208.985%2012.23%209.09-4.482%203.51-10.13%205.605-16.26%205.605-1.055%200-2.096-.06-3.122-.184%205.794%203.717%2012.676%205.882%2020.067%205.882%2024.083%200%2037.25-19.95%2037.25-37.25%200-.565-.013-1.133-.038-1.693%202.558-1.847%204.778-4.15%206.532-6.774z%22%2F%3E%3C%2Fsvg%3E");
}
.modal-body a .btn-icon:hover{
    background-color:#0c7abf;
}
.btn-text{
    display: inline-block;
    vertical-align: top;
    margin-left: 3px;
}
.modal-body a{
    position: relative;
    height: 20px;
    padding: 5px 14px 5px 6px;
    font-weight: 500;
    color: #fff;
    cursor: pointer;
    background-color: #1b95e0;
    border-radius: 3px;
    box-sizing: border-box;
}
.modal-body a:hover{
    background-color:#0c7abf;
}

3） 添加jQuery事件处理程序

$(document).ready(function(){
    $('.modal-body a .btn-icon, .modal-body a').hover(function(){
        $('.modal-body a .btn-icon, .modal-body a')
        .css('background-color', '#0c7abf');
    },
    function(){
        $('.modal-body a .btn-icon, .modal-body a')
        .css('background-color', '#1b95e0');
    })
})

就是这样。所以现在你在弹出窗口中有FF和Chrome中的按钮。如果需要，可以调整按钮和图标的样式，使其看起来更好。

希望这能有所帮助。

或者直接使用jQuery:克隆按钮

$(function() {
  $('#myModal').on('shown.bs.modal', function(e) {
    if ($(".modal-body").find('.twitter-share-button').size())
        return;
    $('.twitter-share-button:first').clone().appendTo('.modal-body');
  });
});
