扩展jQuery easyui datagrid增加动态改变列编辑的类型
$.extend($.fn.datagrid.methods, { addEditor : function(jq, param) { if (param instanceof Array) { $.each(param, function(index, item) { var e = $(jq).datagrid('getColumnOption', item.field); e.editor = item.editor; }); } else { var e = $(jq).datagrid('getColumnOption', param.field); e.editor = param.editor; } }, removeEditor : function(jq, param) { if (param instanceof Array) { $.each(param, function(index, item) { var e = $(jq).datagrid('getColumnOption', item); e.editor = {}; }); } else { var e = $(jq).datagrid('getColumnOption', param); e.editor = {}; } } });
使用方式：
为itemid字段添加一个editor
function test_add(){ $("#tt").datagrid('addEditor', { field : 'itemid', editor : { type : 'validatebox', options : { required : true } } }); }
删除itemid字段的editor: function test_remove(){ $("#tt").datagrid('removeEditor', 'itemid'); }
注：两个方法，第二个参数都可以传递数组。
