ag-grid 无法读取属性“setRowData”，因为 gridOptions.api 未定义答案

【问题标题】：ag-grid Cannot read property 'setRowData' because gridOptions.api undefinedag-grid 无法读取属性“setRowData”，因为 gridOptions.api 未定义

【问题描述】：

我有一个在项目中工作的 ag-grid。但是现在当我将相同的内容移植到另一个页面时，我遇到了一些错误.. 我试图避免其间的 http 调用，并直接尝试通过

设置 ROW 数据

 $scope.gridOptions.api.setRowData(RowDatas);

但错误是“TypeError: Cannot read property 'setRowData' of undefined”

所以在调试时我意识到 api 是 Undefined 。这是我的完整代码。请检查我错过了什么..

【解决方案1】：

同样的问题似乎是由于方法被调用两次引起的。在第一次定义api之前，使得内部代码会崩溃。在第二遍中，定义了 api。

OnGridReady 对我不起作用，使用 vue 的 nextTick 或超时也不起作用。

最终通过使用 if 解决了它：

if (this.gridOptions.api) {
    this.gridOptions.api.setFilterModel(null);
}

这允许它第一次越过它而不崩溃，然后第二次抓住它并完成工作。

（希望这对某人有所帮助。让我很沮丧。）

【解决方案2】：

只有在网格初始化后，网格 api 才会准备就绪。您可以为此使用 gridReady 事件：

$scope.gridOptions = {
    onGridReady: function() {
        $scope.gridOptions.api.setRowData(...your data);
    }

【解决方案3】：

试试这个：

 onGridReady: function(params) {
            params.api.setRowData(...your data);
        }
