在几个合并的页面中定义一个全局的变量，我在别页面中怎么获取到全局变量的值？

$(function(){

	load();

});

	var actionEntityListObj;//定义全局变量 活动

	function load() {

		$.ajax({

			url : "${pageContext['request'].contextPath}/web/ajax/queryNewReq",

			type : "POST",

			dataType : "json",

			success : function(data) {

				if (data != "" && data != null) {

					actionEntityListObj = data;

					var options = "";

					$("#reqSelect").html("");

					if (actionEntityListObj[0].isBegin == 1) {//已经采集过的入口

						queryPageFrameInfo(actionEntityListObj[0].id);

					}

					for (var i = 0; i < actionEntityListObj.length; i++) {

						var actionEntity = actionEntityListObj[i];

						var reqaction = actionEntity.host

								+ actionEntity.applyName;//请求URL

						options += "<option value=\""+actionEntity.id+"\">"

								+ reqaction + "</option>";

					}

					$("#reqSelect").append(options);

				}

				t = setTimeout(load, 1000);

			}

		});

	}

$(function(){

	window.setInterval('getRequestAction()', 1000);

	

	$("#butId").click(function(){

		var val = jQuery("#reqJSON option:selected").val();

		window.open("/SimBox/rule/toRulePage?id="+val);

	});

});

function getRequestAction(){

	

	var url = "${pageContext['request'].contextPath}/web/ajax/queryNewReq";

	var args = {'dateTime' : new Date()};

	

	$.post(url,args,function(data){

		

		if (data != "" && data != null) {

			

			var options = "";

			for (var i = 0; i < data.length; i++) {

				var actionEntity = data[i];

				var reqaction = actionEntity.host

						+ actionEntity.applyName;//请求URL

				options += "<option value=\""+actionEntity.id+"\">"

						+ reqaction + "</option>";

			}

			$("#reqJSON").append(options);

		}

	},'JSON');

}

alert(actionEntityListObj.length);//Undefined
