我想在网格的列中显示另一个商店的值,但是在显示网格之后可以加载商店,因为它的大小。我想要这样的东西:
renderer: function(value, metaData, record, rowIndex, colIndex, gridStore, view) {
var store = Ext.getStore('someBigStore');
if (store.getCount() > 0) {
return store.getById(value).get('name'); // If store is already loaded show value immediately
} else {
store.on('load', function(){
var displayValue = store.getById(value).get('name');
// -> how to insert the displayValue into the right place of the grid ?
});
return 'loading...' // show waiting message
}
}
我如何存档?

好吧,我明白了,框架中没有任何功能可以做到这一点,但是有一点DOM浏览:
store.on('load', function () {
var row = Ext.fly(view.getNode(rowIndex));
var cell = row.down('td:nth-child(' + (colIndex + 1) + ') .x-grid-cell-inner');
cell.setHTML(getDisplayValue());
}, null, { single: true });
