javascript - Angular.js googlemap 信息窗口按钮单击未传递值？

Question

这里我用信息窗口展示了一些城市，一切正常，但在该信息窗口中我有一个按钮。如果我单击该按钮(获取)，它应该将值传递给函数。任何人都可以帮助我

现在，当我单击该按钮时，我的演示控制台中没有显示任何内容 demo

我想这应该是这样

小解释:问题是，您正在尝试从自定义 html 调用 Angular 函数，该函数从未链接到 Angular ，因此您必须先编译它。

基本上$compile(marker.content)($scope);

<html>

<head>
    <script src="https://maps.googleapis.com/maps/api/js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
    <style>
    #map {
        height: 420px;
        width: 600px;
    }
    
    .infoWindowContent {
        font-size: 14px !important;
        border-top: 1px solid #ccc;
        padding-top: 10px;
    }
    
    h2 {
        margin-bottom: 0;
        margin-top: 0;
    }
    </style>
    <script>
    //Angular App Module and Controller
