避免多次保存提交的js脚本

<table class="table-button">
        <tr>
            <td>
                <input name="save" type="button" value="保存" onClick="return doSubmit()">
                <input name="back" type="reset" value="重置">
            </td>
        </tr>
    </table>
     

<script type="text/javascript">

     function doSubmit() {
         if (!check()) return false;
        document.forms[0].action = "<%=rootPath%>/Action.do";
        setAllDisabled(document.forms[0]);
        document.forms[0].submit();
     }
    function check(){
        if(document.getElementById("linkman").value==""){
            alert("请输入联系人！");
 document.getElementById("linkman").focus();
            return false;
        }

  return confirm("是否继续确认?");
 }

     function setAllDisabled(obj) {
        for (var i = 0; i < obj.all.length; i++) {
            if (obj.all[i].type == "button" || obj.all[i].type == "reset" || obj.all[i].type == "submit") {
                obj.all[i].disabled = true;
            }
        }
    }
</script>

 

 

================

button置灰的控制

    document.all.BC.disabled = true;
    document.all.CZ.disabled = true;
