onkeypress与submit问题
<input name= "aa " type= "text " style= "width:30px " onKeyPress= "return event.keyCode> =48&&event.keyCode <=57 " value= "0 "/>
<input type= "submit " name= "Submit " value= "提交登记信息 " onkeypress= "form_in.submit " />
现在问题是这样的
在input aa中我加了onkeypress来验证输入数字，可为什么我在input aa中输入完毕后直接敲回车不能自动提交，而是要手动呢
------解决方案--------------------
<input name= "aa " type= "text " style= "width:30px " onKeyPress= "return event.keyCode> =48&&event.keyCode <=57||event.keyCode=13 " value= "0 "/>
