ajax提交表单

     $.ajax({
                type: "POST",//方法类型
                dataType: "json",//预期服务器返回的数据类型
                url: "../json/importAction_Pro.action" ,
                data: $('#fom').serialize(),
                success: function (result) {
                	debugger
                    if (result.hrefResult == 'job') {
                    	window.location.href = "../userManage/job.jsp" ;
                    }else if(result.hrefResult == 'timerJob'){
                    	window.location.href = "../userManage/timerTaskList.jsp" ;
                    }else{
                    	alert("异常！");
                    }
                },
                error : function() {debugger
                    alert("异常！");
                }
            });

下面提供一个自定义alert框，基于bootstrap的

<link rel="stylesheet" href="../css/global-theme/bootstrap/3.0.1/css/bootstrap.css">
<script type="text/javascript" src="../js/jquery/jquery-1.8.3.min.js"></script>
<script src="../css/global-theme/bootstrap/3.0.1/js/bootstrap.min.js"></script>

<!-------------------------- 模态框用于alert 和confirm -------------------------->
<!-- 模态框（Modal） -->
<div class="modal fade" id="alert" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
	<div class="modal-dialog">
		<div class="modal-content">
			<div class="modal-header">
				<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
				<h4 class="modal-title" id="myModalLabel">提示</h4>
			</div>
			<div class="modal-body"></div>
			<div class="modal-footer">
				<!-- <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button> -->
			</div>
		</div>
		<!-- /.modal-content -->
	</div>
	<!-- /.modal -->
</div>

<script  type="text/javascript">
function closeAlert(){
	$('#alert').modal("hide");
	location.reload();
}
function myAlert(Msg){
	$('#alert .modal-body').html(Msg);
	$('#alert .modal-footer').empty().append("<button type='button' class='btn btn-default' data-dismiss='modal'>关闭</button>");
	$('#alert').modal({keyboard: true});
}
function myConfirm(title,Msg ,nofunc,yesfunc,noText,yesText){
	$("#alert #myModalLabel").html(title ? title : "提示");
	$('#alert .modal-body').html(Msg);
	$("#alert .modal-footer").empty().append("<button type='button' class='btn btn-default' data-dismiss='modal' onclick='"+nofunc+";'>"+(!noText ? '否':noText)+"</button><button type='button' class='btn btn-danger' data-dismiss='modal' onclick='"+yesfunc+";'>"+(!yesText ? '是':yesText)+"</button>");
	$('#alert').modal({keyboard: true});
}
</script>
