Button调用的模式对话框:单击按钮时,将触发事件,结果事件引用e.relatedTarget未定义.那么,如何从处理程序中获取调用按钮？e似乎不包含对调用按钮的任何引用.

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

<!-- 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>

jQuery的:

$('#myModal').on('show.bs.modal', function (e) {
  console.log(e.relatedTarget) // do something...
})

我正在command not found...使用我在 package.json 中定义的 bin模块。为什么？ 我认为它应该自动将本地命令映射到路径中。

在我的模块的 package.json 中：

  "bin": {
    "testme": "./misc/testme"
  },

./misc/testme 脚本：

#!/usr/bin/env node
console.log("this is a test");

它出现在node_modules/.bin目录中

$ ls node_modules/.bin

但是， …

我似乎无法使用npm install更新npm：

$ npm -v
5.6.0
$ sudo npm install -g npm@latest
/usr/bin/npm -> /usr/lib/node_modules/npm/bin/npm-cli.js
/usr/bin/npx -> /usr/lib/node_modules/npm/bin/npx-cli.js
+ npm@5.7.1
updated 1 package in 11.905s
$ npm -v
5.6.0
