E.预防更改模式文本后打开A模式时,默认设置不起作用。模式是在不更改内容的情况下打开的
单击模式触发器按钮时,我正在尝试更改模式正文文本。但情态是开放的,但情态正文文本并没有改变。 这是MODEL的代码
<button type="button" class="btn btn-info open-modal" data-remote="false" data-toggle="modal" data-target="#myModal">Register</button>
<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
然后是防止默认事件的来源
$('.open-modal').click(function(e)
{
e.preventDefault();
alert('hello i am jquery');
$('#myModal').modal('show');
});
为什么警告(‘hello,我是jQuery’);行没有执行?
解决方案
当您的Html优先于jQuery时可能会发生这种情况,因为您的按钮指定要使用以下属性打开的目标模式
data-remote="false" data-toggle="modal" data-target="#myModal"
删除它们,jQuery就会正常
$('.open-modal').click(function(e)
{
e.preventDefault();
alert('hello i am jquery');
$('#myModal').modal('show');
});
