Question

jQuery Cide：

function modal(this) {
        alert($(this).data("id"));
    }

HTML代码：

<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-id="<?php echo $state['ID']?>" onclick='modal(this)'>Open Modal</button>

Bootstrap Modal

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

错误：

Uncaught ReferenceError: modal is not defined at HTMLButtonElement.onclick

我已经在文档就绪函数之外定义了模态，但它显示的模态未定义错误如何解决此错误？

Answer 1

这是工作片段。

function modal(ref) {
	alert($(ref).data("id"));
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-id="1" onclick='modal(this)'>Open Modal</button>

Answer 2

阅读本文：Why can't I use onClick to execute a function inside a jQuery $(document).ready function?

为按钮添加ID：id="btnModal"
删除此内容：onclick='modal(this)'

把它放在document.ready之外）：

$('#btnModal' ).click(function() 
 {
    $('#myModal').modal('show');
 });

模态未定义错误
