Question

我有两个twitter分享按钮，一个在主体上，另一个在一个bootstrap模式中。

“共享”按钮均适用于Chrome，但不适用于Firefox。在Firefox上，第一个分享按钮是外侧模态工作但是当我打开模态时我无法看到分享按钮。

这是一个错误吗？这个问题有解决办法吗？

这是我的代码

Answer 1

它看起来像一个bug，因为小部件按钮隐藏在Firefox中，而这个css由Twitter提供。但是，我找到了解决方法 - 基本上你可以自己创建缺失的按钮。

1）改变modal-body div的内容，如下所示：

<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）在页面中添加以下样式：

.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');
    })
})

那就是它。所以现在你在弹出窗口里面有FF和Chrome的按钮。您可以调整按钮和图标的样式，以便在必要时使其看起来更好。

希望这有帮助。

Answer 2

或者继续使用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');
  });
});
