创建按钮添加删除编辑jqgrid

Question

我已经创建了一个 jqgrid，并且通过启用属于 jqgrid 库的这些功能，我成功地创建了添加、删除、编辑功能。我想在 table 之外创建按钮添加、删除、编辑功能，这是我的代码：

    <table id="list47"></table>
<div id="plist47"></div>

<script>

    var mydata = JSON.parse('@DATA_QUERIED'),
        editSettings = {
            checkOnUpdate: true,
            reloadAfterSubmit: false,
            closeOnEscape: true,
            savekey: [true, 13],
            closeAfterEdit: true
        },
        addSettings = {
            checkOnUpdate: true,
            reloadAfterSubmit: false,
            savekey: [true, 13],
            closeOnEscape: true,
            closeAfterAdd: true
        },
        delSettings = {
            onclickSubmit: function () {
                var $this = $(this), p = $this.jqGrid("getGridParam"), newPage = p.page;

                if (p.lastpage > 1) {// on the multipage grid reload the grid
                    if (p.reccount === 1 && newPage === p.lastpage) {
                        // if after deliting there are no rows on the current page
                        // which is the last page of the grid
                        newPage--; // go to the previous page
                    }
                    // reload grid to make the row from the next page visable.
                    setTimeout(function () {
                        $this.trigger("reloadGrid", [{ page: newPage }]);
                    }, 50);
                }

                return true;
            }
        },
        removeTheOptionAll = function (elem) {
            // We use "value" in the searchoption property of some columns of the colModel.
            // The option {"": "All"} neams "No filter" and should be displayed only
            // in the searching toolbar and not in the searching dialog.
            // So we use dataInit:removeTheOptionAll inside of searchoptions to remove
            // the option {"": "All"} in case of the searching dialog
            if (elem != null && typeof elem.id === "string" && elem.id.substr(0, 3) !== "gs_") {
                // we are NOT in the searching bar
                $(elem).find("option[value=\"\"]").remove(); // remove "All" option
            }
        };


    $(document).ready(function () {

        jQuery("#list47").jqGrid({
            data: mydata,
            datatype: "local",
            autowidth: true,
            height: 'auto',
            rowNum: 15,
            rowList: [5, 10, 20],
            colNames: ['USER_ID', 'USER_NAME', 'LOGIN_NAME', 'PASSWORD', 'DESCRIPTION', 'GROUP_ID', 'EMAIL', 'ACTIVE', 'ORGANIZATION_ID'],
            colModel: [
                { name: 'USER_ID', index: 'USER_ID', width: 100, },
                { name: 'USER_NAME', index: 'USER_NAME', width: 140,edittype: "textarea" },
                { name: 'LOGIN_NAME', index: 'LOGIN_NAME', width: 140,edittype: "textarea" },
                { name: 'PASSWORD', index: 'PASSWORD', width: 140,edittype: "textarea" },
                { name: 'DESCRIPTION', index: 'DESCRIPTION', width: 140,edittype: "textarea" },
                { name: 'GROUP_ID', index: 'GROUP_ID', width: 140,edittype: "textarea" },
                { name: 'EMAIL', index: 'EMAIL', width: 200,edittype: "textarea" },
                { name: 'ACTIVE', index: 'ACTIVE', width: 70, sorttype: "float",formatter: "number", editable: true },
                { name: 'ORGANIZATION_ID', index: 'RGANIZATION_IDz', width: 140, sorttype: "float",formatter: "number", editable: true }
            ],
            cmTemplate: {editable: true, searchoptions: {clearSearch: false }},
            pager: "#plist47",
            viewrecords: true,
            sortname: 'USER_ID',
            gridview: true,
            grouping: true,
            rownumbers: true,
            autoencode: true,
            viewrecords: true,
            ignoreCase: true,
            caption: "Đây là ví dụ mẫu về Grid",
            ondblClickRow: function (rowid) {
                    var $this = $(this), selRowId = $this.jqGrid("getGridParam", "selrow");
                    if (selRowId !== rowid) {
                        // prevent the row from be unselected on double-click
                        // the implementation is for "multiselect:false" which we use,
                        // but one can easy modify the code for "multiselect:true"
                        $this.jqGrid("setSelection", rowid);
                    }
                    $this.jqGrid("editGridRow", rowid, editSettings);
                }
        }).jqGrid("navGrid", "#plist47", {}, editSettings, addSettings, delSettings, {
                multipleSearch: true,
                overlay: false,
                onClose: function () {
                    // if we close the search dialog during the datapicker are opened
                    // the datepicker will stay opened. To fix this we have to hide
                    // the div used by datepicker
                    $("div#ui-datepicker-div.ui-datepicker").hide();
                }
            }).jqGrid("filterToolbar", { defaultSearch: "cn" });

    });
</script>

这是该代码的图片：picture 1 所以我在 jqgrid 的底部添加了 del edit，现在我想在 jqgrid 之外创建一个按钮，如：

您可以使用插入、更新删除的方法来完成此操作。对于更新或删除，您需要获取选定的 ID 并调用该方法。例如，编辑行的代码如下所示。

$("#button_edit").click( function() {
    var selcted_row = $("#grid").jqGrid('getGridParam', 'selrow');
    if(selected_row) {
        $("#grid").jqGrid("editGridRow",selected_row, editSettings);
    } else {
        alert("please select row");
    }
});

执行与删除和添加行类似的操作。查看方法的文档。
