Question

使用twitter bootstrap框架进行Web应用程序。我正在使用一个模态，其中我称之为另一个模态，在另一个模态上有1个模态。目前，如果单击关闭“x”按钮，它将关闭两个模态窗口。我只想关闭顶级模态。

Modal类定义从bootstrap.js中的第750行开始。

模态HTML

<div class="modal fade hide modal-creator" id="myModal_crop_image" style="display: none;height:600px;" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" data-target="#myModal_crop_image">×</button>
        <h3>Create New Gallery</h3>
    </div>
    <div class="modal-body">
        <img style="height:50%;" src="<?php echo base_url(); ?>data/001/images/album/014.jpg" alt="" />
    </div><!-- /modal-body -->

    <div class="modal-footer">

</div>

BootStrap JS

!function ($) {

  "use strict"; // jshint ;_;


 /* MODAL CLASS DEFINITION

关于我如何解决这个问题的任何想法？

Answer 1

在您拥有data-dismiss="modal"的模态定义中，添加data-target="#theIdOfTheModal"

这将告诉它只关闭那个特定的模态

我创建了一个演示这个的小提琴，它实际上有或没有数据目标： Fiddle!

Answer 2

添加到模态隐藏方法（最顶层的行）

e & e.stopPropogation();

这将阻止冒泡活动给父母和其他孩子。

另外，在hide()中传递事件参数（以便它变为hide(e)）在escape方法中。

Answer 3

在取消和关闭按钮中删除此：data-dismiss =“modal”;
然后添加一个类，例如：“close_modal”;
在javascript中创建一个委托函数，如下所示：

使用Javascript：

$(document).on('click', 'button:button.close_modal', function ( event ) {
  event.preventDefault();
  var $this = $(event.currentTarget);
  var modalId = $this.closest('div.modal').attr('id');
  $('#'+modalId+'').modal('hide');
});

Answer 4

替代

$('#myModal .close').click();
