按钮调用模态对话框：当单击按钮时,事件触发生成的事件引用e.relatedTarget未定义.那么,如何从处理程序中获取调用按钮？ e似乎没有包含对调用按钮的引用.
<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>@H_403_3@
jQuery的：
$('#myModal').on('show.bs.modal',function (e) {
console.log(e.relatedTarget) // do something...
})@H_403_3@
解决方法
看看下面的
Bootply example.
当运行show事件似乎包括对e.relatedTarget的适当引用.
$('#myModal').on('show.bs.modal',function (e) {
var button = e.relatedTarget;
if (button != null)
{
alert("Launch Button ID='" + button.id + "'");
}
})@H_403_3@
看看Bootply example,看看你自己的代码是否偏离了它. (我从您提供的link直接复制了原始的Bootstrap示例代码片段.)
我希望这有帮助.祝你好运.
