按钮上的Jquery打开弹出窗口，用于引导程序

Question

当我点击下面的按钮

   <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
        Launch demo modal
    </button>

我打开弹出窗口（模态）

<!-- 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">&times;</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>

我参考下面的例子，

我的问题：

如何使用javascript / jquery在按钮单击时打开#myModal？

任何帮助将不胜感激。

谢谢。

Answer 1

给一个ID来唯一地标识按钮，让我们说myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

来自同一链接的代码

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/jquery-ui.js" type="text/javascript"></script>
<link href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/themes/blitzer/jquery-ui.css"
    rel="stylesheet" type="text/css" />
<script type="text/javascript">
    $(function () {
        $("#dialog").dialog({
            modal: true,
            autoOpen: false,
            title: "jQuery Dialog",
            width: 300,
            height: 150
        });
        $("#btnShow").click(function () {
            $('#dialog').dialog('open');
        });
    });
</script>
<input type="button" id="btnShow" value="Show Popup" />
<div id="dialog" style="display: none" align = "center">
    This is a jQuery Dialog.
</div>

答案取决于您提供的示例链接：

即

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal('show');
