我正在创建一个Extjs网格。其中大部分列都是可编辑的。我需要的是,如果用户更改模糊的任何列值,我将调用我的方法根据其他列值进行一些计算。并将列值替换为计算值.code就在这里。
var incomeTaxOverrideModel = new Ext.grid.ColumnModel([{
id : 'fromDate',
header : "From Date",
dataIndex : 'fromDate',
width : 80,
renderer : drenderer,
editor : this.fromDateEditor
}, {
id : 'toDate',
header : "To Date",
dataIndex : 'toDate',
width : 80,
renderer : drenderer,
editor : this.toDateEditor
}, {
id : 'rawTax',
header : "Raw Tax",
dataIndex : 'rawTax',
width : 80,
align : 'right',
selectOnFocus : true,
editor : new Ext.form.NumberField({"blur":this.calculateTaxForword}),
renderer : Gts.payItemRenderer()
}, {
id : 'surcharge',
header : "Surcharge",
dataIndex : 'surcharge',
width : 80,
align : 'right',
selectOnFocus : true,
editor : new Ext.form.NumberField({}),
renderer : Gts.payItemRenderer()
}, {
id : 'cess',
header : "Cess",
dataIndex : 'cess',
width : 80,
align : 'right',
selectOnFocus : true,
editor : new Ext.form.NumberField({}),
renderer : Gts.payItemRenderer()
}, {
id : 'totalTax',
header : "Total Tax",
dataIndex : 'totalTax',
width : 80,
align : 'right',
selectOnFocus : true,
editor : new Ext.form.NumberField({}),
renderer : Gts.payItemRenderer()
}, {
id : 'taxAmount',
header : "Taxable Income",
dataIndex : 'taxAmount',
width : 100,
align : 'right',
selectOnFocus : true,
editor : new Ext.form.NumberField({}),
renderer : Gts.payItemRenderer()
}, {
id : 'remarks',
header : "Remarks",
dataIndex : 'remarks',
width : 250,
editor : new Ext.form.TextField({})
}, {
id : 'modifiedDate',
header : "Modified On",
dataIndex : 'modifiedDate',
width : 100,
renderer : Ext.util.Format.dateRenderer('d M Y h:i:s A'),
width : 150
}
]);
this.itoGrid = new Ext.grid.EditorGridPanel({
store : this.itoStore,
cm : incomeTaxOverrideModel,
autoExpandColumn : 'remarks',
autoScroll : true,
containerScroll : true,
frame : false,
stripeRows : true,
width : 830,
height : 233,
clicksToEdit : 1,
layout : 'fit',
loadMask : true,
tbar : [this.addAction, this.deleteAction],
trackMouseOver : true
});
我在方法
上创建calculateTaxForword :function(){
console.log(this.itoGrid)
//console.log(this.itoGrid.getStore().getModifiedRecords())
}
但它不会出现任何东西。我必须根据原始tax.surcharge和cess来计算价值所以我需要我方法中的所有价值。如果有任何一个请帮助
