如何在其处理程序中删除此操作列项中的图标?
{
header: 'Activate',
xtype: 'actioncolumn',
align: 'center',
width: 30,
sortable: false,
items: [{
icon: './Scripts/extjs/examples/shared/icons/fam/accept.png',
tooltip: '',
handler: function (grid, rowIndex, colIndex) {
var rec = grid.getStore().getAt(rowIndex);
if (rec.get('status') == '1') { // if active, don't show icon
this.up('actioncolumn').icon = '';
}
}
...
