我需要在单击extjs网格操作列中的图标时更改该图标的背景色。
handler: function(grid, rowIndex, colIndex) {
//Need to change the background color of the delete icon
}

这样做:
handler: function(grid, rowIndex, colIndex) {
Ext.query('td.x-action-col-cell img',grid.getNode(rowIndex))[0].style.setProperty('background-color','#000')
}
