【问题描述】：
我查看了许多其他堆栈问答，但无法到达让我的代码正常工作所需的位置。 我觉得我想做的很简单，显然不适合我。
我有 2 个选择部分，每个部分会产生所需的不同信息。
-first 是 oceanVal
-秒是fishVal
我希望用户选择的值随后被发送到我的 javascript，以用作以下从 JSON var 文件中获取数据的过程中的变量，然后最终将其发送回我在 oceanOutput 中的 HTML（谢谢为您提供帮助）。
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 没有。 因此，如果您想查看它的操作，只需执行提示，这就是我想要它执行的操作，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 - 我要缩小它。）
JSON：
var jsonObject = {"ocean_measure":{"gulf":{"fish":{"dolphin":{"name":"Mahi-mahi","length":"none","limit":"10 per person or 60 per vessel whichever is less"},"blackfin tuna":{"name":"Blackfin Tuna","length":"not regulated","limit":"The default bag limit for all unregulated species is two fish or 100 pounds per day, whichever is more"},"snook":{"name":"Snook","length":"Not less than 28 inches total length (TL) or more than 33 inches TL","closed":"Dec. 1-end of February; May 1-Aug. 31","limit":"1 per harvester per day","remarks":"Snook permit required for harvest when saltwater license required.

此外，JSON 文件目前很小，因此虽然 if(input == option){code...} 等... 并不理想，因为我将获得 JSON 文件每个海湾和大西洋都有多达 40 多条鱼。
