问题描述
看看我的小提琴在这里发生了什么:http://jsfiddle.net/tbH5H/
Take a look at what happens in my fiddle here: http://jsfiddle.net/tbH5H/
我正在尝试使用 jgrid 实现适当的渐进增强.一切都很好,除了我不知道如何在第一次加载时为 jqgrid 提供正确的寻呼机信息.我的服务器端脚本为 SEO 机器人转储 JSON 和相应的 HTML 表.但是我怎样才能在第一次本地加载时为 jqgrid 提供正确的总页数?正如您在小提琴中看到的那样,分页器在远程数据拉取后正常工作.
I'm trying to achieve proper progressive enhancement using jgrid. Everything works great, except I don't know how to give jqgrid the correct pager information on first load. My server side script dumps the JSON and a corresponding HTML table for SEO bots. But how can I also give the correct total page count to jqgrid on this first local load? The pager works correctly after a remote data pull as you can see in the fiddle.
HTML
<table id="grid">
<tr><th>ID</th><th>State</th></tr>
<tr><td>1</td><td>Alaska</td></tr>
<!-- etc...server side script dumps this out for SEO... -->
</table>
<div id="pager"></div>
JS
$("#grid").jqGrid({
datatype:'local',
// Server side script dumps this JSON out for first load only,
// other requests will come from remote source, see further down...
data: [{"id":1,"state":"Alabama"},
{"id":2,"state":"Alaska"},
{"id":3,"state":"Arizona"},
{"id":4,"state":"Arkansas"},
{"id":5,"state":"California"},
{"id":6,"state":"Colorado"},
{"id":7,"state":"Connecticut"},
{"id":8,"state":"Delaware"},
{"id":9,"state":"Florida"},
{"id":10,"state":"Georgia"}],
height: 250,
width: 450,
rowNum:10,
colNames:['ID','State'],
colModel:[
{name:'id', index:'id', width:50},
{name:'state', index:'state', width:100}
],
caption: "States of the USA",
pager: '#pager'
});
$("#grid").jqGrid('navGrid', '#pager',{edit: false, add: false, del: false, search: false, refresh: true});
// Convert the grid to read remotely, but don't trigger a unnecessary reload...
// (because queries are expensive! We shouldn't need to run them twice!)
$('#grid').jqGrid("setGridParam",{datatype:"json", mtype:"POST", url:"/some/url/here"});
$('#grid').jqGrid("setGridParam",{postData:data});
推荐答案
知道了!
我需要使用 localReader
.查看新小提琴:http://jsfiddle.net/2UCk6/
I needed to use localReader
. See new fiddle: http://jsfiddle.net/2UCk6/
localReader: {
// These values would be inserted on first page load from server-side script
page: function(obj) { return 1; },
total: function(obj) { return 5; },
records: function(obj) { return 50; }
},
