//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;
}
