Question

我正在使用$ .getJson（）函数返回位于单独的json文件中的数组，并将其存储到本地数组var中。我遇到的问题是我只能从json中取回25个项目中的20个。 $ .getJson是否对退回的项目数有限制？

这就是我使用代码的方式：

使用Javascript：

$.getJSON('data/gridData1.json',function(json){
                console.log("Json length is: " + json.length);
                var grid = json;
                filterGrid(grid, ele);
            });

JSON：

控制台日志显示结果：20。我有什么遗漏吗？

JSON响应的大小没有设置限制，不仅限于此在HTML或XML响应上。你可以拥有非常大的JSON响应而没有问题。 GET与POST将与此无关。那些只是不同的请求发送到服务器的方式; GET和GET的响应格式 POST是完全相同的。

虽然在向服务器请求大量数据的情况下，但首选Post，但服务器的响应在GET和POST中都没有限制

$ .getJson（）响应限制
