我正在尝试设置一个包含 14 种不同模态的页面。我之前对它们进行了设置，以便它们都能正常打开，而且它们已经起作用了。但是我发现了一些东西可以让我在打开时使它们可以拖动。所以我想弄清楚如何做到这一点，并最终让它工作，但只有一种模式。除非我更改代码以反射(reflect)该模态的名称，否则我的其他模态不会打开。然后第一个模态不起作用。请告诉我如何使 JavaScript 代码为我的所有模态通用。
这是我的脚本代码:
<script type="text/javascript">
window.onload=function(){
$('#btn1').click(function() {
// reset modal if it isn't visible
if (!($('.modal.in').length)) {
$('.modal-dialog').css({
top: 110,
left: 500
});
}
$('#modal1').modal({
backdrop: true,
show: true
});
$('.modal-dialog').draggable({
handle: ".modal-header"
});
});
}
</script>
这是我的模态框代码，只有两个模态框而不是全部 14 个:
<button id="btn1" class="btn btn-info btn-lg" data-target="#modal1">Modal 1</button>
<div class="modal fade" id="modal1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" >Modal 1</h4>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
<div class="container">
<button id="btn2" class="btn btn-info btn-lg" data-target="#modal2">Modal 2</button>
<div class="modal fade" id="modal2" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" >Modal 2</h4>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
如果我在带有新“#btn”和/或新“#modal”的脚本之后添加另一个脚本，则后者仅有效。
如果我在第一个“btn”和/或“modal”之后添加一个逗号，这会使两个模态重叠。
有人可以帮忙吗？我做错了什么？
最佳答案
如果您想避免在 JavaScript 中设置所有模态框(并且假设您不想为每个模态框添加额外的编码)，您是否可以通过 HTML 数据属性让它们全部切换？然后你只需要初始化你的可拖动代码。
