<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8" /><script type="text/javascript"> function save() { var form1 = document.getElementById('form1'); var query = ""; var hash = {}; for (var i = 0; i != form1.length; ++ i) { var obj = form1.elements[i]; var type = obj.type; var name = obj.name; var value = obj.value; if (type == "text") { if (query != "") { query += "&"; } query += encodeURIComponent(name) + "=" + encodeURIComponent(value); } else if (type == "radio") { if (!hash[name] && obj.checked) { hash[name] = true; if (query != "") { query += "&"; } query += encodeURIComponent(name) + "=" + encodeURIComponent(value); } } } alert(query); }</script></head><body><form id="form1"> <input name="textName1" type="text" id="textName1" /> <input name="textName2" type="text" id="textName2" /> <input type="radio" name="r1"value="测试1" checked>测试1<br> <input type="radio" name="r1"value="测试2" checked>测试2<br> <input type="button" name="Submit" value="Submit" onclick="save()" /></form></body>
