html: <input type="text" name="keyword" id="keyword" onkeydown="entersearch()"/> <input type="button" onclick="search()"/> 注意:不要用form js: function search(){ $keyword = $("#keyword").val(); window.location.href = "/list-0-0-0-0-"+$keyword+"-0-0-1.html"; } function entersearch(){ //alert(dd); var event = window.event || arguments.callee.caller.arguments[0]; if (event.keyCode == 13) { search(); } }
