回车提交事件,和阻止回车提交

阻止回车提交
  <form runat="server" id="form1" onkeypress="javascript:return SAASkeyDown(event)" >
回车提交
 <script>
        function getKeyCode(evt) {
            if (typeof (evt) == 'string') return evt.charCodeAt(0);
            return document.all ? event.keyCode : (evt && evt.which) ? evt.which : 0;
        }

        function SAASkeyDown(event) {
            if (getKeyCode(event) == 13) {
                return false;
            }
        }
        function SearchEnter(event){
             if (getKeyCode(event) == 13) {
                newsSearch();
            }
        }
        function newsSearch()
        {   
          var key=document.getElementById("newsSearchKey").value;
          if(key=="输入关键字")
          {
            alert("请输入关键字");
          }else
          {
            window.location.href="http://search.soufun.com/search?dir=news&q="+escape(key);
          }
        }
       </script>
      
        <input type="hidden" name="dir" value="news">
        <div class="left kuang">
          <input name="q" size="20" type="text" class="kuang" id="newsSearchKey" value="输入关键字" onfocus="if(this.value=='输入关键字')this.value='';" onblur="if(this.value=='')this.value='输入关键字';"  onkeydown="SearchEnter(event);"/>
        </div>
        <div class="left">
          <input type="button" value=" " class="subBut" onclick="newsSearch()"/>
        </div>

所以我总结了一下,用Javascript提交表单大概有两种写法(根据我目前的理解)

1. document.formName.submit();

2.  var form = document.getElementById(id);
    form.submit();

button调用form.submit()方法时不触发onSubmit事件的解决办法(转)
<input   type="button"   value="test"   onclick="if(document.myForm.onsubmit()!=false)document.myForm.submit();">
