Soluzione per il problema di non poter selezionare il checkbox (casella di controllo) in Extjs gridpanel in base alle condizioni di una riga

具体代码如下所示：

Ext.define('AM.view.test.ReceiptList', { 
  extend: 'Ext.grid.Panel', 
  alias: 'widget.receiptlist', 
  id : 'receiptlist', 
  selModel : {}} 
    selType : 'checkboxmodel', 
    mode : 'SIMPLE', 
    checkOnly : true, 
    renderer : function(v,p,record) { 
      if (record.data.XR0003 == '0') { 
        return '<div class="x-grid-row-checker"> </div>'; 
      }else{ 
        return ''; 
      } 
    } 
  , 
  listeners: { 
    beforeselect: function(grid, record, index, eOpts) { 
      if (record.get('XR0003')!=0) { 
        return false; 
      } 
    } 
  } 
}); 

Code Explanation:

1. The red标注 (annotation) is the key code;

2. The code in renderer indicates that the checkbox is displayed only when the conditions are met during rendering;

3. The code in listeners indicates that a condition judgment is made before selection, and it is not selected if it is not equal to 0;

4. You can combine the two methods according to your own needs.
