Question

这是RESTful数据格式

{"user":[
           {"id":"aupres","passwd":"aaa","age":45,"name":"father"},
           {"id":"hwa5383","passwd":"bbb","age":40,"name":"mother"},
           {"id":"julian","passwd":"ccc","age":15,"name":"son"}

我的jqGrid客户端成功调用上述数据。下图显示了结果：

但是这段代码无法显示对jqGrid的响应。这是我的客户代码

也会忽略不存在的参数datatype: "xml"。如果将其解释为XML数据，则返回错误。
您包含的输出来自contentType而非来自onloadError。 onloadComplete的参数为onloadError，jqXHR，textStatus。您包含了jqXHR对象的控制台输出。见the answer。
您应该在JavaScript中声明变量：使用errorThrown代替var $Grid = $("#grid");。在顶部函数的开头包含$Grid = $("#grid");指令有助于检测此类错误（请参阅here）。同样地，我建议您在每个语句后添加分号（请参阅"use strict"和console.log(status)）。
您应该在所有问题中包含您使用的jqGrid版本以及哪个fork（free jqGrid - 我的fork，商业Guriddo jqGrid JS或版本中的旧jqGrid＆lt; = 4.7）。叉子的可能性将越来越不同。因此，使用（或可以使用）哪一个很重要。
