要通过AJAX调用传递JavaScript变量，请替换以下内容-
var page = parseInt(getUrlParameter('page'));与-
var page = +getUrlParameter("page") || 100;尝试以下代码以通过AJAX调用正确传递变量-
<html>
<script>
function getUrlParameter ( param ) {
return param === "page" ? 500 : false;
}
var page = +getUrlParameter("Demo") || 100;
alert(page);
page = +getUrlParameter("page") || 100;
alert(page);
</script>
<body>
</body>
</html>
