给form标签加 οnkeydοwn=“if(event.keyCode==13)return false;”
进止input回车，提交表单
给input标签添加 οnkeydοwn=“BindEnter(event)”
或者给body添加 οnkeydοwn=“BindEnter(event)”
就会执行 BindEnter()方法了
<body onkeydown="BindEnter(event)" ><form class="form-x" onkeydown="if(event.keyCode==13)return false;" ><input onkeydown="BindEnter(event)" type="text" id="card_no" name="card_no" class="infos" /><input type="button" onclick="subform()" value="提交" /></form><script>function BindEnter(obj) {if(obj.keyCode == 13){var str=$('.form-x').serialize()window.location.href="{:url('qcwap/gamecontinue/memlists')}?"+str}}</script>
</body>
