Question

我新学到了jqgrid。我希望通过动态数据和列创建网格。我问my question并阅读此link但我需要更多示例

Answer 1

在my answer对您之前回答的评论中，我简要介绍了如何根据服务器返回的数据更改列标题的想法。为了更清楚，我为你准备了一个演示。

我试图使演示大多简短明了，所以它有一些限制：

来自服务器的不同响应中未更改的列数
格式化程序和列的width在来自服务器的不同响应中不会更改。

可以减少或删除所有限制，但在您的情况下，上述限制已经泛滥。此外，我想首先描述实现的主要思想。

The demo在网格上方有树状按钮，允许从服务器重新加载数据，但是来自不同的URL。点击＆＃34;加载俄语标题＆＃34;按钮网格上的标题将使用服务器响应中的文本动态更改，并且将看到以下图片

数据格式如下：

{
    "model": {
        "c1": { "label": "Client" },
        "c2": { "label": "Date" },
        "c3": { "label": "Amount" },
        "c4": { "label": "Tax" },
        "c5": { "label": "Total" },
        "c6": { "label": "Paid" },
        "c7": { "label": "Shipped via" },
        "c8": { "label": "Notes" }
    },
    "data": [
        {"id": "10",  "cell": ["test",   "2007-10-01", "200.00", "10.00", "210.00", "true",  "TN", "note"  ] },
        {"id": "20",  "cell": ["test2",  "2007-10-02", "300.00", "20.00", "320.00", "false", "FE", "note2" ] },
        {"id": "30",  "cell": ["test3",  "2007-09-01", "400.00", "30.00", "430.00", "false", "FE", "note3" ] },
        {"id": "40",  "cell": ["test4",  "2007-10-04", "200.00", "10.00", "210.00", "true",  "TN", "note4" ] },
        {"id": "50",  "cell": ["test5",  "2007-10-31", "300.00", "20.00", "320.00", "false", "FE", "note5" ] },
        {"id": "60",  "cell": ["test6",  "2007-09-06", "400.00", "30.00", "430.00", "false", "FE", "note6" ] },
        {"id": "70",  "cell": ["test7",  "2007-10-04", "200.00", "10.00", "210.00", "true",  "TN", "note7" ] },
        {"id": "80",  "cell": ["test8",  "2007-10-03", "300.00", "20.00", "320.00", "false", "FE", "note8" ] },
        {"id": "90",  "cell": ["test9",  "2007-09-01", "400.00", "30.00", "430.00", "false", "TN", "note9" ] },
        {"id": "100", "cell": ["test10", "2007-09-08", "500.00", "30.00", "530.00", "true",  "TN", "note10"] },
        {"id": "110", "cell": ["test11", "2007-09-08", "500.00", "30.00", "530.00", "false", "FE", "note11"] },
        {"id": "120", "cell": ["test12", "2007-09-10", "500.00", "30.00", "530.00", "false", "FE", "note12"] }
    ]
}

JavaScript代码中最重要的部分是

jsonReader: { root: "data" },
beforeProcessing: function (data) {
    var $self = $(this), model = data.model, name, $colHeader, $sortingIcons;
    if (model) {
        for (name in model) {
            if (model.hasOwnProperty(name)) {
                $colHeader = $("#jqgh_" + $.jgrid.jqID(this.id + "_" + name));
                $sortingIcons = $colHeader.find(">span.s-ico");
                $colHeader.text(model[name].label);
                $colHeader.append($sortingIcons);
            }
        }
    }
}

演示中使用的完整JavaScript位于

之下

var $grid = $("#list");
$grid.jqGrid({
    url: "DynamicHeaderProperties.json",
    datatype: "json",
    colModel: [
        { name: "c1", width: 70 },

                    $colHeader.append($sortingIcons);
                }
            }
        }
    },
    loadonce: true,
    height: "auto"
});
$("#en").button().click(function () {
    $grid.jqGrid("setGridParam", {
        datatype: "json",

$("#ru").button().click(function () {
