ExtJs GridFilter 操作

表格列小箭头下拉下来的GridFilter 筛选操作

grid.getFilterPlugin().clearFilters();
grid.getFilterPlugin().getFilter('dataindex').setValue("value"); //string filter
grid.getFilterPlugin().getFilter('dataindex').setValue(true); //bool filter
grid.getFilterPlugin().getFilter('dataindex').setValue({gt:2, lt:9, eq:5}); //numeric filter
grid.getFilterPlugin().getFilter('dataindex').setValue({before: new Date(2008,0,1), after:..., on:...}); //date filter
grid.getFilterPlugin().getFilter('dataindex').setValue(['item1', item2]); //list filter

grid.getFilterPlugin().getFilter('dataindex').setActive(false); //turn off filter

grid.filterHeader.clearFilter();

Ext.encode(this.up('grid').filterHeader.getFilterValues());

loadFilter(this.up('grid').filterHeader);

var loadFilter = function (plugin) {
            plugin.setValue({
                Id : ">5",
                Company: "!Inc.",
                Price: ">50<70",
                Visible: 1
            });
        };
