粘性列中的ag-grid菜單

Question

有沒有辦法為粘性列中的每一行添加菜單（在Ag網格中）？

在官方文件中沒有提到這種功能，所以我不確定它是否可能。 我嘗試了幾種方法，但菜單總是被困在粘性列包裝器中。

我能夠（至少）部分工作的唯一方法是設置：

.ag-body-container .ag-row {
        z-index: 0;
    }

    .ag-ltr .ag-hacked-scroll .ag-pinned-right-cols-viewport {
        overflow: visible !important;
    }

但這完全破壞了垂直滾動。

 var columnDefs = [ {headerName: "ID", width: 50, valueGetter: 'node.id', cellRenderer: 'loadingRenderer' }, {headerName: "Athlete", field: "athlete", width: 150}, {headerName: "Age", field: "age", width: 90}, {headerName: "Country", field: "country", width: 120}, {headerName: "Year", field: "year", width: 90}, {headerName: "Date", field: "date", width: 110}, {headerName: "Sport", field: "sport", width: 210}, {headerName: "Gold", field: "gold", width: 300}, {headerName: "Silver", field: "silver", width: 400}, {headerName: "Bronze", field: "bronze", width: 200}, {headerName: "Menu", field: "", width: 100, pinned: 'right', cellRenderer: 'menuRenderer' } ]; function MenuRenderer( params ) { } MenuRenderer.prototype.init = function(params) { this.eGui = document.createElement('div'); this.eGui.classList.add('menu'); var menuElement = ` <a href="#"> * </a> <div class="menu--list"> </div> `; this.eGui.innerHTML = menuElement; }; MenuRenderer.prototype.getGui = function() { return this.eGui; }; var gridOptions = { components:{ loadingRenderer: function(params) { if (params.value !== undefined) { return params.value; } else { return '<img src="./loading.gif">' } }, 'menuRenderer': MenuRenderer }, columnDefs: columnDefs, rowBuffer: 0, rowModelType: 'infinite', paginationPageSize: 100, cacheOverflowSize: 2, maxConcurrentDatasourceRequests: 2, infiniteInitialRowCount: 0, maxBlocksInCache: 2, //embedFullWidthRows:true, onGridReady: function (params) { params.api.sizeColumnsToFit(); } } // wait for the document to be loaded, otherwise, // ag-Grid will not find the div in the document. document.addEventListener("DOMContentLoaded", function() { // lookup the container we want the Grid to use var eGridDiv = document.querySelector('#myGrid'); // create the grid passing in the div to use together with the columns & data we want to use new agGrid.Grid(eGridDiv, gridOptions); agGrid.simpleHttpRequest({url: 'https://raw.githubusercontent.com/ag-grid/ag-grid-docs/master/src/olympicWinners.json'}).then(function(data) { var dataSource = { rowCount: null, // behave as infinite scroll getRows: function (params) { console.log('asking for ' + params.startRow + ' to ' + params.endRow); // At this point in your code, you would call the server, using $http if in AngularJS 1.x. // To make the demo look real, wait for 500ms before returning setTimeout( function() { // take a slice of the total rows var rowsThisPage = data.slice(params.startRow, params.endRow); // if on or after the last page, work out the last row. var lastRow = -1; if (data.length <= params.endRow) { lastRow = data.length; } // call the success callback params.successCallback(rowsThisPage, lastRow); }, 500); } }; gridOptions.api.setDatasource(dataSource); }); });

Answer 1

我完全放棄了在單元格中添加菜單的想法。

我會做的是：

• 添加網格外的菜單，隱藏，
• 將鏈接保留在單元格中（這會稍后觸發菜單）
• 將click事件添加到此鏈接
• 為菜單創建一個類（可以是全局的，因為只有一個菜單，具有更改的上下文）
  • 這將隱藏/顯示菜單
  • 有參數，存儲上下文（來自網格的數據，或其他）
• 來自網格的鏈接上的點擊事件將具有顯示菜單的代碼

這樣的事情：為簡潔起見，此示例沒有錯誤處理。

var gridMenu = function(selector) {
    var instance = this;
    instance.element = document.querySelector(selector);
    instance.context = null; // this can be any data, depends on your project

    // sender is the link from your cell
    // context is your data (see above)
    instance.open = function(sender, context) {
        instance.context = context;
        // you may even add the sender element to your context

        instance.element.style.display('block');
        // alternatively, you could use instance.element.classList.add('some_class_to_make_menu_visible')
        // you may need to add some positioning code here (sender would contain valuable data for that)
    }

    instance.close = function () {
        instance.context = null;
        instance.element.style.display = 'none';
        // or you may remove visibility class
    }

    // click events for menu items (if you use some Javascript processing, and the menu doesn't use simple links)
    instance.menuItem1Click = function(e) {
         // do whatever you wish here
         instance.close();
         // call this at the end of each of your menu item click event handlers
    }

    // ... more click event handlers for your other menu items (one for each menu item)

    return instance;
}

// Create your menu item somewhere in your document ready code, or even where you initiate your grid (before initializing the grid)
var menu = new gridMenu("#my_awesome_floating_menu");

這是網格內鏈接的示例點擊事件：

function cellLinkClick(event) {
    var context = {}; // whatever data you may want to send to the menu
    menu.open(event, context);
}
