在表单中获取选项值，然后在 url 中使用它 - Get option value in form, then use it in a url

我有一个表格，你可以选择一个国家，国家包含一个值。
例如，使用该值34，<br>如果您将其放在类似 'http://packarmy.nl/img/nation/' . $_GET['nationvalue'] . '.png' 的 url 中，我可以得到一个图像

但我希望它立即更新，我尝试使用此代码：

$(function() {
    var update = function() {
        $('#photoans').text(        
            $.map($('#photo').serializeArray(),function(a) {
                    return a.value;
                    }).join(", ")
        );
    };
    update();
    $('#photo').change(update);
})

这当然会让你 http://futhead.cursecdn.com/static/img/16/clubs/"<div id=photoans>34</div>".png"，所以这不起作用。我希望有人能帮助我。谢谢！

如果我理解正确，我想这就是你想要的：

$("#country").change(function(){
	var curSelection = $(this).val();
  var urlOfImage = "http://ariellarestaurant.com/Scripts/Widgets/Timer/odometer/" + curSelection + ".png";
	$("img").attr("src",urlOfImage);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<img src="http://ariellarestaurant.com/Scripts/Widgets/Timer/odometer/0.png" />
<br>
<select id="country">
  <option value="0">0</option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
</select>

更新： 使用输入字段

$("#countryInput").keyup(function(){
	var curInput = $(this).val(); // Current Input URL
	$("#img2").attr("src",curInput);  
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<img id="img2" src="http://ariellarestaurant.com/Scripts/Widgets/Timer/odometer/0.png" />
<br>
URL : <input type="text" id="countryInput" />
<p>  
  To understand copy and paste this url: <b>http://ariellarestaurant.com/Scripts/Widgets/Timer/odometer/1.png</b>
</p>

你需要开始 php 和结束 php 标签来回显 $_GET 内容值nation_id

<img src='http://futhead.cursecdn.com/static/img/16/clubs/"<?php echo  $_GET['nation_id'] ?>"' >

如果您设置 PHP 交互器
