    String sql_jqgrid="SELECT g.org_id,g.title,g.date_reg,g.em_name, g.view_count,s.filename, g.download_count FROM org g,orgpds s WHERE g.org_id=s.org_id(+)";

我得到了这个值

{＆＃34; currpage＆＃34;：1，＆＃34;总记录＆＃34;：45，＆＃34;总页数＆＃34;：5，＆＃34; invdata＆＃34;：[{＆＃ 34; org_id＆＃34;：＆＃34; 4＆＃34;＆＃34;标题＆＃34;：＆＃34; dfdfdfdff＆＃34;＆＃34; date_reg＆＃34;：＆＃34; 2009-10 -05 00：00：00.0＆＃34;＆＃34; DOWNLOAD_COUNT＆＃34;：＆＃34; 0＆＃34;＆＃34; VIEW_COUNT＆＃34;：＆＃34; 9＆＃34;}，{＆＃ 34; org_id＆＃34;：＆＃34; 5＆＃34;＆＃34;标题＆＃34;：＆＃34; AAA＆＃34;＆＃34;文件名＆＃34;：＆＃34; aa1.zip＆＃34;＆＃34; date_reg＆＃34;：＆＃34; 2010-09-29 00：00：00.0＆＃34;＆＃34; DOWNLOAD_COUNT＆＃34;：＆＃34; 2＆＃34;＆＃34; VIEW_COUNT＆＃34;：＆＃34; 26＆＃34;＆＃34; em_name＆＃34;：＆＃34;管理＆＃34;}]}

它的jqGrid来源

$("#list").jqGrid({

                       rowList: [5, 10, 20, 50],
                       autowidth:true, 
                       width: function(){$("#list").setGridWidth($(this).width(), true);}, 
                       height: '100%',

                       });

readyState = 4，responseText为right，status = 200，statusText = ok！但是我得到了一个错误信息＆＃34; syntaxError意外的令牌＆＃34; ＆LT; （在铬中）

Answer 1

我已经解决了自己的问题。

我只需添加＆＃34; out.close（）; ＆＃34; org_list_json.jsp的底部。之后jqGrid运作良好。

但我不知道为什么。

如果有人知道，你能告诉我吗？

jqgrid readyState = 4，responseText是对的，status = 200，statusText = ok！但它不起作用
