如何在没有Ajax请求的情况下加载jqGrid？

Question

我发现/看到的每个jsGrid使用示例都显示了通过Ajax请求加载的数据。我想根据已有的数据加载网格;除非技术要求，否则单独的请求是完全不必要的。

我真的希望我的控制器，拉网格中显示所需要的数据，把它传递给我的看法，让jqGrid的做它的事基于本地数据，而不是发起另一个请求。我无法想象这是不可能的，但我甚至没有发现一个不使用url配置的例子来获取JSON格式的数据。

当然，数据装载不是这个窄，但也有人点我到不是AJAX为中心的一个例子吗？

谢谢。

从版本3.7开始，jqgrid拥有全面的本地支持，包括数据排序分页等。

所以哟可以使用data或datastr参数。需要使用localReader可参见documentation。这里是一个简单的例子：

var mydata = [ 
    { id: "1", invdate: "2007-10-01", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "2", invdate: "2007-10-02", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "3", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }, 
    { id: "4", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "5", invdate: "2007-10-05", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "6", invdate: "2007-09-06", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }, 
    { id: "7", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "8", invdate: "2007-10-03", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "9", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }, 
    { id: "10", invdate: "2007-10-01", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "11", invdate: "2007-10-02", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "12", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }, 
    { id: "13", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "14", invdate: "2007-10-05", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "15", invdate: "2007-09-06", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }, 
    { id: "16", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" }, 
    { id: "17", invdate: "2007-10-03", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" }, 
    { id: "18", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" } 
]; 
var grid = $("#list"); 
grid.jqGrid({ 
    data: mydata, 
    datatype: "local", 
    colNames: ['Inv No', 'Date', 'Client', 'Amount', 'Tax', 'Total', 'Notes'], 
    colModel: [ 
     { name: 'id', index: 'id', key: true, width: 70, sorttype: "int" }, 
     { name: 'invdate', index: 'invdate', width: 90, sorttype: "date" }, 
     { name: 'name', index: 'name', width: 100 }, 
     { name: 'amount', index: 'amount', width: 80, align: "right", sorttype: "float" }, 
     { name: 'tax', index: 'tax', width: 80, align: "right", sorttype: "float" }, 
     { name: 'total', index: 'total', width: 80, align: "right", sorttype: "float" }, 
     { name: 'note', index: 'note', width: 150, sortable: false } 
    ], 
    pager: '#pager', 
    rowNum: 10, 
    rowList: [5, 10, 20, 50], 
    sortname: 'id', 
    sortorder: 'asc', 
    viewrecords: true, 
    height: "100%", 
    caption: "Simple loading of local data" 
}); 
grid.jqGrid('navGrid', '#pager', { add: false, edit: false, del: false, search: true, refresh: true });

看那jqGrid的例子here。展开“加载数据”并点击“阵列数据”。
