我的html页面

<!--

<!DOCTYPE html>
<html>
    <head>
        <title></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
    <body>
        <h4>Click here to go to <a href="stats">My servlet page</a></h4>

        <h4>Servlet</h4>

        <script type="text/javascript">
    function loadStats() {

        //document.location='stats';
        window.open("stats");

    }
    loadStats.call();


</script>






    </body>
</html>


单击此处转到
Servlet
函数loadStats（）{
//document.location='stats'；
窗口打开（“统计”）；
}
loadStats.call（）；

html页面在一个新窗口中打开servlet数据，但是如何在html页面上显示servlet数据（使用javascript）？

您可以通过多种方式来实现，但大多数推荐

如果您只想向用户显示

stats

，您也可以尝试。

我正在使用。这对我很有用，没问题，很乐意帮忙。当做

jQuery.ajax({
    url: "stats",
}).done(function (msg) {
    jQuery('body').append(jQuery(msg));
});
