我已经查看了许多其他堆栈问答，但无法到达我需要让我的代码正常工作的地方。
我觉得我想做的事情很简单，显然不适合我。
我有两个选择部分，每个部分产生所需的不同信息。
-首先是 oceanVal
-第二个是fishVal
我希望用户选择的值发送到我的 javascript，在以下从 JSON var 文件获取数据的过程中用作变量，然后最终将其发送回 oceanOutput 中的 HTML（感谢您的帮助） ）。
html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>OceanMeasure</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<h1>Ocean Measure</h1>
<div>
<p>Where will you be fishing?</p>
<form>
<select name="oceanVal" id="oceanVal">
<option value="" disabled="disabled" selected="selected">Please select</option>
<option value="gulf">Gulf</option>
<option value="atlantic">Atlantic</option>
</select>
</div>
<div>
<p>What fish would you like to look up?</p>
<select name="fishVal" id="fishVal">
<option value="" disabled="disabled" selected="selected">Please select</option>
<option value="dolphin">Dolphin</option>
<option value="blackfin tuna">Blackfin Tuna</option>
<option value="snook">Snook</option>
</select>
</div>
<button>Get Info</button>
</form>
<div id="oceanOutput"></div>
<script type="text/javascript" src="js/jquery-3.1.0.min.js"></script>
<script type="text/javascript" src="js/data.json"></script>
<script type="text/javascript" src="js/main.js"></script>
</body>
</html>
javascript:
(function(){
// var userOcean = prompt("What ocean will you be fishing in?");
// var userFish = prompt("What fish would you like to look up?");
var userOcean = document.getElementById("oceanVal");
var userFish = document.getElementById("fishVal");
console.log(
"\n\nfish: "+jsonObject.ocean_measure[userOcean].fish[userFish].name+
"\n\nlength: "+jsonObject.ocean_measure[userOcean].fish[userFish].length+
"\n\nclosed: "+jsonObject.ocean_measure[userOcean].fish[userFish].closed+
"\n\nlimit: "+jsonObject.ocean_measure[userOcean].fish[userFish].limit+
"\n\nremarks: "+jsonObject.ocean_measure[userOcean].fish[userFish].remarks
);
})();
我的提示有效，但我的 html 不行。
因此，如果您想看到它的运行，只需按照提示操作，这就是我想要它做的事情，但在单击时使用我的表单。
我还没有到达输出部分。
（不确定是否需要，但这是我的 JSON - 我将缩小它。）
