在分页页脚中，不是应该将0的页面[1]说成"0的页面[0]"；如果没有找到记录? [英] In the Paging footer, aren't the Page [1 ] of 0 supposed to say "Page [0 ] of 0" if no record is found?
本文介绍了在分页页脚中，不是应该将0的页面[1]说成"0的页面[0]"；如果没有找到记录?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我注意到，如果没有记录要返回，那么分页页脚是否应该说"0之0"而不是"0之1"?
I noticed if there's no records to be returned then shouldn't the Paging footer say "0 of 0" instead of "1 of 0"??
此外，也不应该禁用分页"文本框.
Also, shouldn't the Paging textbox be disabled as well.
这是我发回jqGrid的JSON响应
This is the JSON response I sent back to jqGrid
{ "total":0, "page":0, "records":0, "rows":[] }
我正在使用jqGrid 4.5.0版

这是使用Firefox firebug的快照.如您所见，json结果就是您要我执行的操作，请使用"page":"0"而不是"page":0.网页中的jqGrid显示为1而不是0.
Here's the snapshot using Firefox firebug. As you can see the json result is what you asked me to do, use "page":"0" instead of "page":0 . The jqGrid in the webpage showed 1 instead of 0.
推荐答案
我认为问题出在您应将page的整数值更改为 string 值:
You should change integer value of page to the string value:
{ "total":0, "page":"0", "records":0, "rows":[] }
或
{ "total":"0", "page":"0", "records":"0", "rows":[] }
大部分与文档.
更新:演示复制您的问题，并且另一个演示使用固定的JSON数据(而"page":"0" "page":0).您如何查看修复工作.
UPDATED: The demo reproduce your problem and another demo uses the fixed JSON data ("page":"0" instead of "page":0). How you can see the fix work.
更新2 :我现在看到问题在于使用loadonce: true.要解决此问题，可以使用
UPDATED 2: I see now that the problem is in usage of loadonce: true. To fix the problem one can use
localReader: {
page: function (obj) {
return obj.page !== undefined ? obj.page : "0";
}
}
请参见更多演示.
更新3 :我发布了完整请求将解决问题.该修补程序已经合并到github上jqGrid的主要代码中(请参见此处).
UPDATED 3: I posted the full request which would fix the problems. The fix is already merged (see here) to the main code of jqGrid on the github.
