基本上，我想按下一个按钮（与某个人匹配），该按钮会弹出另一个页面的弹出式窗口（现在使用模式），该页面将根据哪个人就是这样。我使用的是w3school的基本模板，我可以得到一个按钮，但是当我尝试将一个按钮添加到列表中以匹配某个人时，该模式不会打开。显然，每个按钮分配给一个人，他们将需要有自己的元素ID，但为什么我甚至不能让一个按钮工作？ 它是下面片段中的“在地图上显示”按钮。 最上方的“在地图上显示”按钮的作用在于它会显示模式，但列表中的相同按钮不起作用。Javascript按钮打开模式;按钮在列表中不起作用
预先感谢您。

奇妙的......那么什么是var btn，现在是btns，它是一个名为myBtn的所有按钮的数组？ –
这是正确的。您可以使用btn变量为每个名为“myBtn”的按钮执行任何操作。 –
非常感谢！所以假设如果我希望模式为每个按钮显示不同的东西，我是否会将它引用为btn [i]？ 理想情况下，每个显示地图按钮都会突出显示地图上的表格，该地图是另一个.html文档，并且使用数组添加了表格，我正在制作这些表格，但是我能否使用btn [i ]引用给定的按钮？ –
