请帮助解决这个非常烦人的问题。我正在使用 for 循环遍历数据数组并创建多个网格。它运行良好，但过滤器功能未正确绑定（它仅绑定到创建的最后一个网格）这是代码：
// this function iterates over the data to build the grids
function buildTables() {
// "domain" contains the dataset array
for (i = 0; i < domains.length; i++) {
var dataView;
dataView = new Slick.Data.DataView();
var d = domains[i];
grid = new Slick.Grid('#' + d.name, dataView, d.columns, grids.options);
var data = d.data;
// create a column filter collection for each grid - this works fine
var columnFilters = columnFilters[d.name];
// this seems to be working just fine
// Chrome console confirms it is is processed when rendering the filters
grid.onHeaderRowCellRendered.subscribe(function (e, args) {
$(args.node).empty();
$("<input type='text'>")
.data("columnId", args.column.id)
.val(columnFilters[args.column.id])
.appendTo(args.node);
});
// respond to changes in filter inputs
$(grid.getHeaderRow()).delegate(":input", "change keyup", function (e) {
var columnID = $(this).data("columnId");
if (columnID != null) {
// this works fine - when the user enters text into the input - it
// adds the filter term to the filter obj appropriately
// I have tested this extensively and it works appropriately on
// all grids (ie each grid has a distinct columnFilters object
var gridID = $(this).parents('.grid').attr('id');
columnFilters[gridID][columnID] = $.trim($(this).val());
dataView.refresh();
}
});
//##### FAIL #####
// this is where things seem to go wrong
// The row item always provides data from the LAST grid populated!!
// For example, if I have three grids, and I enter a filter term for
// grids 1 or 2 or 3 the row item below always belongs to grid 3!!
function filter(row) {
var gridID = $(this).parents('.grid').attr('id');
for (var columnId in grids.columnFilters[gridID]) {
if (columnId !== undefined && columnFilters[columnId] !== "") {
var header = grid.getColumns()[grid.getColumnIndex(columnId)];
//console.log(header.name);
}
}
return true;
}
grid.init();
dataView.beginUpdate();
dataView.setItems(data);
dataView.setFilter(filter); // does it matter than I only have one dataView instance?
dataView.endUpdate();
grid.invalidate();
grid.render();
总而言之，除了过滤器功能之外，每个功能似乎都适当地绑定到每个网格。当我在任何网格中输入过滤条件时，它只返回最后一个网格中的行。
我花了几个小时试图找出错误，但不得不承认失败。非常感激任何的帮助。
