UI-Grid

Question

在UI-grid "select All"复选框中，选中后，select显示当前页面以及其他页面可见的所有记录。

问题 - 怎样才能select行只显示在当前页面。

笨蛋 http://plnkr.co/edit/gHiER0A2Oaia4HMWChcG?p=preview

尝试了 api $scope.gridApi.selection.selectAllVisibleRows(); 但它没有 select 仅显示在当前页面中的行。如果您单击 "Select Visible Rows" 按钮并移至下一页，则那里的记录也会 selected.

其他详情apiselectAllVisibleRows

在 ui-grid 函数中检查时 selectAllVisibleRows。 row.visible returns true 为 all the rows across all pages。

selectAllVisibleRows: function (evt) {
    if (grid.options.multiSelect === false) {
        return;
     }

    var changedRows = [];
        grid.rows.forEach(function (row) {
        if (row.visible) {
           if (!row.isSelected && row.enableSelection !== false){
              row.setSelected(true);
              service.decideRaiseSelectionEvent( grid, row, changedRows, evt );
           }
        } else {
          if (row.isSelected){
             row.setSelected(false);
             service.decideRaiseSelectionEvent( grid, row, changedRows, evt );
          }
        }});
    service.decideRaiseSelectionBatchEvent( grid, changedRows, evt );
    grid.selection.selectAll = true;
},

尝试使用 for 循环 这里是 plunker link!

Answer 2

为了 select 当前网格页面中的行，您必须在注册其 API 时为 ui-grid v4.4.9 rowSelectionChangedBatch 事件添加一个处理程序。方法。正如您所指出的，它认为所有未过滤的行都是可见的。它不排除未在当前网格页面上呈现的行。因此，我们不得不自己动手：

        onRegisterApi: function (gridApi) {

            gridApi.selection.on.rowSelectionChangedBatch(null, function (rows) {
                var grid = this.grid;
                // you'll need ui-grid v4.4.9 or better 
                // otherwise you'll need to invert getSelectAllState()
                // as explained at https://github.com/angular-ui/ui-grid/issues/5411
                var isAllSelected = grid.api.selection.getSelectAllState();
                // when select all is checked, the default behavior is to select all grid rows on all pages
                // so we have to deselect them all first before we select just the ones on the visible page
                grid.api.selection.clearSelectedRows(null);
                if (isAllSelected) {
                    // select only the rows displayed in the current grid page
                    var startIndex = (grid.options.paginationCurrentPage - 1) * grid.options.paginationPageSize;
                    var endIndex = startIndex + grid.options.paginationPageSize;
                    for (let i = startIndex; i < endIndex; i++) {
                        let row = grid.rows[i];
                        row.isSelected = true;
                    }
                }
            });
        },

onRegisterApi: function(gridApi) {
    gridApi.selection.on.rowSelectionChangedBatch($scope, function() {

        // check for ui-grid version to revert opposite value
        var isAllSelected = gridApi.selection.getSelectAllState();

        if (isAllSelected) { 

            // unselect all rows as select all button selects all rows by default
            gridApi.selection.clearSelectedRows();

            /* Will fetch only grid rows visible on page. It will fetch the correct 
               rows even if you have applied sorting, pagination and filters. */
            var gridRows = this.grid.getVisibleRows();


            // function to set Selected to only visible rows
            angular.forEach(gridRows, function(gridRow) { 
                gridRow.setSelected(true);
            });
        }
        $scope.selectedRows = gridApi.selection.getSelectedRows();
   });
}
