对于一个我在Web设计课程中正在做的项目来说，我已经为这个错误而苦苦挣扎了大约一天，而我还远远没有弄清楚如何解决它。对于该项目，我使用两种API的组合来读取用户指定的位置，使用Google GeoCoding API获取该位置的纬度和经度，然后使用该纬度和经度显示该位置的当前天气。问题是，无论我做什么，我将位置对象（名称，纬度和经度）返回到主要index.html文件脚本的函数永远不会正确返回，我相信这可能是因为它异步运行。我对javascript有点陌生，所以如果我对您的答案提出很多问题，请提前道歉。 这是我的location.js文件中的代码：

这是我的index.html中的代码
$(document).ready(function() {
var winWidth = $(window).width();
if (winWidth < 790){
$(".accordContent").hide();
}
$(".accord").click(function() {
$(this).next(".accordContent").slideToggle("fast");
});
});
Andddd，这是我得到的答复： Sample Response Image
答案 0 :(得分：0)
params: {
address: location,
key: googleAPIKey(paste your apikey here)
}
从google获取api密钥，然后将其粘贴到密钥的位置。否则它将无法正常工作。
