    <body background="" onkeypress="return validationOnEnter(event);" onload="self.focus();document.getElementById('').focus()">
    <form method="post" action="" name="welcome" id="welcome" >
....
<input type="hidden" name="submit_flag" id="submit_flag" value="">
....
<a tabindex=""  name="next" id="next" href="javascript:processEnter();" onkeypress="document.getElementById('submit_flag').value='false';document.getElementById('next').focus();">...</a>

以下是js文件部分

function validationOnEnter(event) {
    var browser=navigator.appName;
    var value = false;
    if(browser=='Microsoft Internet Explorer') {
        if (window.event && window.event.keyCode == 13) {
             if(document.getElementById('submit_flag').value != 'false') {
                 processEnter();
                 value= true;
             } else {
                value= true;
             }
          } else {
             value = true;
          }
    }
   if (browser=='Netscape') {
       if (event && event.which == 13) {
          if(document.getElementById('submit_flag').value != 'false') {
             value = processEnter();
          } else {
            value = true;
          }
        } else {
          value = true;
        }
    }
    return value;
}


function processEnter() 
{

    document.welcome.xxd1.datatype    = "numberic";
    document.welcome.xxd1.mandatory   = "no";
    document.welcome.xxd1.description = "xxd1";
    document.welcome.xxd1.minimumlength = "1";
    document.welcome.xxd1.maximumlength = "4";
    document.welcome.xxd1.value = document.welcome.xxd1.value.replace(/^\s+|\s+$/g, '');
    ......
    ......
    ......

    var doSubmitForm = false; 

    doSubmitForm = validate(document.welcome,errorMessages,errorIndex);
    if(doSubmitForm) {
        doSubmitForm = otherFunction1();
    }

    if(doSubmitForm) {
        doSubmitForm = otherFunction2();
    }
    ......

    if(doSubmitForm)
    {  

        document.welcome.submit(); 
    } 
    else {
        document.welcome.submit_flag.value = 'true';
        showAllErrors(errorMessages,errorIndex); 
    }
}


var errorMessages = new Array(10);

var errorIndex = new Object;

var pattern = new Object();
var text = new Object();

pattern.numeric      = /^[0-9]+$/;
text.numeric         = " should only contain numbers";
