是否可以在同一页面上显示两个 ag-grid 实例？就像我正在尝试这样做:

<html style="height: 100%;">

    <head lang="en">
     <meta charset="UTF-8">
        <title>Data Platform - Real Time Monitor </title>
        <script src="../dist/ag-grid-enterprise.js?ignore=notused30"></script>
        <script src="loadingGrid.js"></script>
        <script src="sortGrid.js"></script>

    </head>
<body style="height: 100%; margin: 0px;">


<div style="width: 100%; height: 100%; overflow-x:auto; overflow-y:hidden">
<div id="myGrid2" style="width: 70%; height: 50%;" class="ag-fresh">


        </div>
<div id="myGrid" style="width: 100%; height: 90%; overflow-x:scroll;" class="ag-fresh">


        </div>  
</div>      




  </body>

</html>

然后我使用此链接中的加载数据教程: https://www.ag-grid.com/ag-grid-tutorials/index.php即 loadingGrid.js使用 div id myGrid2和 sortGrid.js使用 div id myGrid .两者都有不同的表。但是只显示一个包含所有数据的表，第二个表显示空表，还有第二个表的列名。如何在同一页面上显示两个 ag-grid 表？

更新:好的，我也用 ag-grid 示例进行了尝试(尝试在同一页面上创建两个 ag-grid 表，但获得相同的输出。您可以使用所有代码: tutorial1.js : 
var columnDefs = [
    {headerName: "Athlete", field: "athlete", width: 150, sort: 'desc'},
    {headerName: "Age", field: "age", width: 90}

];


var gridOptions = {
    columnDefs: columnDefs,
    rowData: null,
    enableSorting: true,
    enableFilter: true,
    enableColResize: true
};


// setup the grid after the page has finished loading
document.addEventListener('DOMContentLoaded', function() {
    var gridDiv = document.querySelector('#myGrid1');
    new agGrid.Grid(gridDiv, gridOptions);

    // do http request to get our sample data - not using any framework to keep the example self contained.
    // you will probably use a framework like JQuery, Angular or something else to do your HTTP calls.
    var httpRequest = new XMLHttpRequest();
    httpRequest.open('GET', '../dist/olympicWinners.json');
    httpRequest.send();
    httpRequest.onreadystatechange = function() {
        if (httpRequest.readyState == 4 && httpRequest.status == 200) {
            var httpResult = JSON.parse(httpRequest.responseText);
            gridOptions.api.setRowData(httpResult);
            console.log(httpResult);
        }
    };
});

教程.js 
var columnDefs = [

    {headerName: "Country", field: "country", width: 120},
    {headerName: "Year", field: "year", width: 90, unSortIcon: true},
    {headerName: "Date", field: "date", width: 110},
    {headerName: "Sport", field: "sport", width: 110},
    {headerName: "Gold", field: "gold", width: 100},
    {headerName: "Silver", field: "silver", width: 100},
    {headerName: "Bronze", field: "bronze", width: 100},
    {headerName: "Total", field: "total", width: 100}
];


var gridOptions = {
    columnDefs: columnDefs,
    rowData: null,
    enableSorting: true,
    enableFilter: true,
    enableColResize: true
};


// setup the grid after the page has finished loading
document.addEventListener('DOMContentLoaded', function() {
    var gridDiv = document.querySelector('#myGrid');
    new agGrid.Grid(gridDiv, gridOptions);

    // do http request to get our sample data - not using any framework to keep the example self contained.
    // you will probably use a framework like JQuery, Angular or something else to do your HTTP calls.
    var httpRequest = new XMLHttpRequest();
    httpRequest.open('GET', '../dist/olympicWinners.json');
    httpRequest.send();
    httpRequest.onreadystatechange = function() {
        if (httpRequest.readyState == 4 && httpRequest.status == 200) {
            var httpResult = JSON.parse(httpRequest.responseText);
            gridOptions.api.setRowData(httpResult);
            console.log(httpResult);
        }
    };
});

索引.html: 
<!DOCTYPE html>
<html style="height: 100%;">

    <head lang="en">
        <meta charset="UTF-8">

        <script src="../dist/ag-grid.js"></script>

        <script src="tutorial.js"></script>
        <script src="tutorial1.js"></script>
    </head>

    <body style="height: 100%; margin: 0px;">

        <div id="myGrid" style="width: 100%; height: 100%;" class="ag-fresh"></div>
        <div id="myGrid1" style="width: 100%; height: 100%;" class="ag-fresh"></div>
    </body>
</html>

您可以从以下位置获取 olympicWinner.json: https://raw.githubusercontent.com/vadimtsushko/ag-grid/master/web/olympicWinners.json

更新1:
我在 tutorial.js 中添加了以下内容: 
function buyside() {
    var filterApi = gridOptions.api.getFilterApi('Sport');
    filterApi.selectNothing();
    filterApi.selectValue('Swimming');
    //filterApi.selectValue('Great Britain');
    gridOptions.api.onFilterChanged();
}

function sellside() {
    var filterApi = gridOptions.api.getFilterApi('Sport');
    filterApi.selectNothing();
    filterApi.selectValue('Gymnastics');
    //filterApi.selectValue('Great Britain');
    gridOptions.api.onFilterChanged();
}


function clearFilters() {
    gridOptions.api.setFilterModel(null);
    gridOptions.api.onFilterChanged();
}

以及 index.html 中的以下行: 
<center><span style="padding-bottom: 4px; display: inline-block;">


            <button onclick="buyside()">Swimming</button>
            <button onclick="sellside()">Gymnastics</button>
            <button onclick="clearFilters()">Clear Filters</button>

        </span></center>

但是单击按钮时没有任何 react 。当页面上只有一个 ag-grid 时，它工作正常。

最佳答案

您遇到了范围界定问题，类似于 this answer explains .由于您全局定义了所有变量，因此当您不希望它们被覆盖时，它们会被覆盖。您有两个选项可以解决此问题:

1 - 在 tutorial1.js 中重命名所有全局命名的变量以在它们之后包含数字 1(或任何你想要的)，这样你就不会意外地再次重写它们。

var columnDefs1 = [
        ...
    ];


var gridOptions1 = {
    columnDefs: columnDefs1,
    ...
};


// setup the grid after the page has finished loading
document.addEventListener('DOMContentLoaded', function() {
    var gridDiv = document.querySelector('#myGrid1');
    new agGrid.Grid(gridDiv, gridOptions1);

    ....
});

2 - 将您的整个代码包装在每个文件中的自调用匿名函数中。这是它的样子: 
(function(){
    var columnDefs = [
        {headerName: "Athlete", field: "athlete", width: 150, sort: 'desc'},
        {headerName: "Age", field: "age", width: 90}

    ];

    ...
})()
