jquery 捕获回车事件的实现代码

用jquery捕获回车事件，记得引入jquery类库文件。

1，js代码：

function getEnter(obj,evt){
if(evt.keyCode == 13){
var target = $(":input").not(":radio,select,:reset");
for(var i=0;i<target.length;i++){
if(target.get(i).name==obj.name){
i++;
if(i==target.length-1){
$(target.get(i)).focus();
// 表单提交
$("form").submit(function(){
formSubmit();
return false;
});
}
$(target.get(i)).focus();
return false;
}
}
}
}

2，html代码：

<form name="consignBillForm"
action="consignBill/addConsignBillUIAction.action" method="post" >
