得到ExtJS的網格面板隱藏列的列索引

Question

我需要隱藏列的列索引extjs grid面板

columnhide: function() { 
      var cell = this.getEl().query('.x-grid-cell-inner'); 

      for(var i = 0; i < cell.length; i++) { 
      if (i%2 != 0){ // Instead of this i, want to change the style to none for the hide column, so i need to get the column index of hide column in grid panel 
        cell[i].style.display= "none"; 
       } 
      } 

Answer 1

使用columnhide聽衆：

columnhide: function(ct, column, eOpts) { 
    alert(column.getIndex()); 
}, 

或者，您可以遍歷網格列並檢查每列的isHidden（）屬性：

Ext.each(grid.columns, function(column, index) { 
    if (column.isHidden()) { 
     alert('column at index ' + index + ' is hidden'); 
    } 
});
