在表单输入后附加URL
[英]Append URL with form input
问题描述
This is my first attempt to write anything in javascript, although this does exactly as intended, I am sure it can be done simpler. 
这是我第一次尝试用javascript编写任何东西，尽管这样做确实符合预期，但我相信它可以更简单地完成。 Not that this script is all that useful, just an exercise in learning something new. 并不是说这个脚本很有用，只是一个学习新知识的练习。 I was also trying not to use the evil document write. 我也试图不使用邪恶的文件写。
So what is the more elegant way of doing this? 那么，这样做的更优雅的方法是什么？
<html>
<body>
<input name="abc" type="text" id="foo">
<button onclick="AddInputValue()">Submit</button>
<p id="displayURL"></p>
<script>
function AddInputValue(){
var domain = "http://site.com?abc="
var qstring = document.getElementById("foo").value;
document.getElementById("displayURL").innerHTML=domain + qstring;
}
</script>
</body>
</html>

If you use jQuery : 如果您使用jQuery ：
<html>
<!-- Include jQuery! -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<body>
<form id="form1">
<input name="abc" type="text" id="foo">
<button type="submit">Submit</button>
</form>
<p id="displayURL"></p>
<script>
$(document).ready(function () {
var form = document.getElementById("form1");
$(form).submit(function () {
var domain = "http://site.com/?";
var data = $(this).serialize();
document.getElementById("displayURL").innerHTML = domain + data;
return false;
});
});
</script>
</body>
</html>
You can even add more form elements and the name of the element will match the query string. 您甚至可以添加更多表单元素，并且该元素的name将与查询字符串匹配。 http://jsfiddle.net/3muu6/ http://jsfiddle.net/3muu6/

Just posting the example in http://jsfiddle.net/3muu6/ . 只需将示例发布在http://jsfiddle.net/3muu6/中 。
Increased the number of inputs. 增加了输入数量。 This is basically what Google Analytics URL Builder does, and was the inspiration for this exercise. 这基本上就是Google Analytics（分析）URL Builder的工作，并且是本练习的灵感。
<html>
<head>
<!-- Include jQuery! -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
</head>
<body>
<form id="form1">
<input name="abc" type="text" id="foo" /><br />
<input name="def" type="text" id="bar" /><br />
<input name="ghi" type="text" id="tar" /><br />
<input name="jkl" type="text" id="boo" /><br />
<button type="submit">Submit</button>
</form>
<p id="displayURL"></p>
<script>
$(document).ready(function () {
var form = document.getElementById("form1");
$(form).submit(function () {
var domain = "http://example.com/?";
var data = $(this).serialize();
document.getElementById("displayURL").innerHTML = domain + data;
return false;
});
});
</script>
</body></html>
Now how to omit a query-string pair when the user leaves an input value blank? 现在，当用户将输入值留空时，如何省略查询字符串对？ Hmm. 嗯。
