【原创】关于回车直接执行事件的方法

1.form表单实现

<html>
<form name="f1" method="post" action="login.asp">
用户名:<input type="text" name="fuser"><br>
密 码:<input type="password" name="fpwd"><br>
<input type="submit" name="b1" value="提交">
</html>

2.jQuery触发事件

<div><input type="text" id="search" name="search" size="28"/><button id="go">GO</button></div> 
<div id="result" class="result"></div>
<script type="text/javascript">
$(document).ready(function(){
    var txt = $(":text");
    $(this).keyup(function(e){      
        if(e.keyCode == 13){
            txt.focus();
        }   
    });
     
    txt.keyup(function(e){
    if(e.keyCode == 13){
        $("#go").click();
    }    
    });
});

$(document).ready(function() { 
    $("#go").bind('click',function(){ 
        var search = $("#search").val();        
        var resultmsg = "Your are searching text"+"<b>"+'"'+search+'"'+"</b>";    
        $("#result").html(resultmsg);
        $("#search").val(""); //clear search text    
    }); 
});
</script>
