如果行具有非常量的高度，则角度 ui-grid 自动高度 [英] angular ui-grid auto height if rows have non-constant height

问题描述

我正在尝试使 angular ui-grid 自动调整高度，以便在不需要滚动条的情况下显示所有行，但如果网格中只有几行，则不会浪费空间.有人问过类似的问题(Angular ui-grid 动态计算网格的高度)，但问题的前提是行高是恒定的.如果行高不同(例如，因为您启用了自动换行)，则该问题的公认解决方案 (https://stackoverflow.com/a/28706349/877570) 将不起作用，因为该问题的解决方案假定行高不变.如果我有一个包含大量文本的单元格，并且文本换行到下一行，则行高不同.

I'm trying to make angular ui-grid automatically resize the height so that all rows are shown without the need of its scrollbar, but without wasting space if there are only a couple rows in the grid. Someone has asked a similar question (Angular ui-grid dynamically calculate height of the grid), but the question presupposes that the row heights are constant. If the row heights are different (for example, because you have word-wrap enabled), then the accepted solution to the problem (https://stackoverflow.com/a/28706349/877570) won't work, because the solution as does the question assumes constant row height. If I have a cell with a large amount of text in it, and the text wraps to the next line, then that rows height is different.

我在这里找到了用户 anhkind 的可能解决方案:(https://github.com/angular-ui/ui-grid/issues/1735)

I found a possible solution by the user anhkind here: (https://github.com/angular-ui/ui-grid/issues/1735)

.ui-grid, .ui-grid-viewport {
  height: auto !important;
}

当然，minRowsToShow 和virtualizationThreshold 应该设置为列表的大小."

"And of course minRowsToShow and virtualizationThreshold should be set to the size of the list."

但是，当我部署他的解决方案时，网格需要更长的时间来呈现.

However, when I deploy his solution, it takes a much longer time for the grid to render.

有人知道如何解决这个问题或有其他解决方案吗?

Does anyone know how to address this or have an alternative solution?

推荐答案

    $scope._minRows = 10;
    $scope._maxRows = 10;

   // Lots of Grid Options, plus data setting going on here.

    $scope.agendaItemsGridOptions.onRegisterApi = function(gridApi) {
        //set gridApi on scope
        $scope.gridApi = gridApi;
    });

    var setMinRowsLogic = function() {
        $scope.gridApi.grid.options.minRowsToShow = $scope._minRows;
        if (!_.isUndefined($scope.agendaItemsGridOptions.data)) {
            var len = $scope.agendaItemsGridOptions.data.length;
            if (len > $scope._maxRows) {

                $scope.gridApi.grid.options.minRowsToShow = $scope._maxRows;
            } else
            if (len < $scope._minRows) {
                $scope.gridApi.grid.options.minRowsToShow = $scope._minRows;
            } else {
                $scope.gridApi.grid.options.minRowsToShow = len;
            }
        }
    };
