EXTJS中grid的数据特殊显示，不同窗口的数据传递

//EXTJS中grid的数据特殊显示
renderer : function(value, metaData, record, rowIndex, colIndex, store, view) {
                    var USED_AMOUNT_ = 0;
                    for (var i = 0; i < matMonthPlanHisList.length; i++) {
                        if(matMonthPlanHisList[i].MAT_NO_ == record.get('MAT_NO_')){
                            USED_AMOUNT_ = matMonthPlanHisList[i].USED_AMOUNT_;
                            break;
                        }
                    }
                    return record.get('AMOUNT_') - USED_AMOUNT_;
                }

不同窗口的数据传递

        var success = window.showModalDialog('preImportMatYearPlan.do?YEAR_=' + Ext.getCmp('YEAR_').getValue() + '&MAT_TYPE_=' + Ext.getCmp('MAT_TYPE_').getValue() + '&random=' + Math.random(), window, 'resizable=yes; dialogWidth=960px; dialogHeight=500px');

var MAT_YEAR_PLN_BATCH_ID_ = '';
    var YEAR_ = '';
    var MAT_TYPE_ = '';if (location.href.split('?')[1] != undefined) {
        var parameters = Ext.urlDecode(location.href.split('?')[1]);
        (parameters.YEAR_ == undefined) ? YEAR_ = '' : YEAR_ = parameters.YEAR_;
        (parameters.MAT_TYPE_ == undefined) ? MAT_TYPE_ = '' : MAT_TYPE_ = parameters.MAT_TYPE_;
    }

常用监听，函数：

Ext.panel.Table
view source
cellclick( Ext.view.Table this, HTMLElement td, Number cellIndex, Ext.data.Model record, HTMLElement tr, Number rowIndex, Ext.EventObject e, Object eOpts )

单击表格单元格时触发。

celldblclick( Ext.view.Table this, HTMLElement td, Number cellIndex, Ext.data.Model record, HTMLElement tr, Number rowIndex, Ext.EventObject e, Object eOpts )

双击表格单元格时触发。

callback : function(options, success, response) {
｝

listeners : {
                load : function(store, records) {
                }
            }

listeners : {
                    'select' : function(combo, records, eOpts) {
    ｝
｝

格式化Double数据处理

renderer : function(value, metaData, record, rowIndex, colIndex, store, view) {
                    return Ext.util.Format.number(value, '0.00');
                }

//不允许为空，需要和类似与Panel的控件的items下的allowBlank : false,一起使用做判断
function _validate(obj) {
        var valid = true;
        for (var i = 0; i < obj.items.length; i++) {
            if (obj.items.getAt(i).xtype != 'button' && obj.items.getAt(i).xtype != 'panel' && !obj.items.getAt(i).validate()) {
                valid = false;
            }
        }
        return valid;
    }
