gridPanel添加按钮
在实际开发中有的时候需要一些下图这样的功能,为了实现下图方法,需要做很多事情!当然有一种很好的方法,但是不安全,不容易维护!为了方便维护所以写了下面的方法!
///添加列单击事件,方便在列内添加功能按钮
Ext.grid.GridPanel.prototype.processEvent = function(name, e){
this.fireEvent(name, e);
var t = e.getTarget();
var v = this.view;
var header = v.findHeaderIndex(t);
if(header !== false){
this.fireEvent("header" + name, this, header, e);
}else{
var row = v.findRowIndex(t);
var cell = v.findCellIndex(t);
if(row !== false){
this.fireEvent("row" + name, this, row, e);
if(cell !== false){
var col =this.colModel.config;
var record= this.store.getAt(row);
if(typeof col.onColumnCilck == "function")
{
col.onColumnCilck(this,record,row,cell,e);
}
this.fireEvent("cell" + name, this, row, cell, e);
}
}
}}
//按钮列
Ext.grid.ButtonColumn =function(text){
var a={
text:text
}
returnfunction(v, p, record){
var tpl= new Ext.Template('<button type="button">{text}</button>');
return tpl.apply(a);
}
}
///添加列单击事件,方便在列内添加功能按钮
Ext.grid.GridPanel.prototype.processEvent = function(name, e){
this.fireEvent(name, e);
var t = e.getTarget();
var v = this.view;
var header = v.findHeaderIndex(t);
if(header !== false){
this.fireEvent("header" + name, this, header, e);
}else{
var row = v.findRowIndex(t);
var cell = v.findCellIndex(t);
if(row !== false){
this.fireEvent("row" + name, this, row, e);
if(cell !== false){
var col =this.colModel.config;
var record= this.store.getAt(row);
if(typeof col.onColumnCilck == "function")
{
col.onColumnCilck(this,record,row,cell,e);
}
this.fireEvent("cell" + name, this, row, cell, e);
}
}
}}
//按钮列
Ext.grid.ButtonColumn =function(text){
var a={
text:text
}
return function(v, p, record){
var tpl= new Ext.Template('<button type="button">{text}</button>');
return tpl.apply(a);
}
}
用法如下:

var sm = new Ext.grid.CheckboxSelectionModel();

},

},{

要问我ColumnPropert是什么?是我自己写的一个方便开发的东西!因为store和grid之间的列写发,不同所以搞了一个这个东西!
代码如下:
// / <reference path="../../extjs2.0/adapter/ext/ext-base.js" />
// / <reference path="../../extjs2.0/ext-all-debug.js" />
// / <reference path="namespace.js" />
/*
* Config= [ {Caption:'', Name:'', Type:'' } ],
*/
ColumnPropert = function(config) {
this.Columns = config;
// Columns:[{Caption:'',Name:'',Type:'',ColumnModelConfig:[],StoreConfig:[]}],
// this.Columns.Caption=
// 获取数据源的字段描述
// VorP是显示,还是打印
this.GetJsonStoreFields = function(VorP) {
var fields = [], ln = this.Columns.length, j = 0;
for (var i = 0;i < ln; i++) {
var column = this.Columns;
var field = {};
// for(var o in column)
// {
// field=column;
// }
// 显示
if (VorP == 'V' && column.IsView == 1 || VorP == null) {
if (column.Name != null) {
field.name = column.Name;
field.type = column.Type;
fields = field;
j++;
}
}
// 打印
if (VorP == 'P' && column.IsPrint == 1) {
if (column.Name != null) {
field.name = column.Name;
field.type = column.Type;
fields = field;
j++;
}
}
}
return fields;
};
// 获取数据源的字段描述
this.GetColumnModel = function(VorP) {
var ColumnModels = [], ln = this.Columns.length, j = 0;
for (var i = 0;i < ln; i++) {
var column = this.Columns;
var ColumnModel = {};
if (column.Type == 'date') {
ColumnModel.renderer = Ext.util.Format.dateRenderer("Y-m-d");// 默认的日期渲染方式
}
if (VorP == 'V' && column.IsView == 1 || VorP == null) {
for (var o in column) {
ColumnModel = column;
}
ColumnModel.header = column.Caption;
ColumnModel.dataIndex = column.Name;
ColumnModel.type = column.Type;
ColumnModels = ColumnModel;
j++;
} else if (VorP == 'P' && column.IsPrint == 1) {
for (var o in column) {

}
ColumnModel.header = column.Caption;
ColumnModel.dataIndex = column.Name;
ColumnModel.type = column.Type;
ColumnModels = ColumnModel;

return ColumnModels;

// 单条记录

j++;
}
} else if (VorP == 'P' && column.IsPrint == 1) {
if (column.Name != null) {
field.name = column.Name;
// field.type=column.Type;
fields = field;
j++;
}
}
}
return fields;
}
// 返回一条新的空记录
this.GetNewRecord = function(VorP) {
var newObj = {}, ln = this.Columns.length;

return newObj;
}
};
/*根据store来渲染grid的列,不需要自己再写额外的渲染方法
* Examples
*
storeConfig:{
store:infoStore,
valueField:'Id',
DisplayField:'Name'
}
*/
ColumnPropert.getStoreRenderer = function(storeConfig) {
return function(value) {
var ln = storeConfig.store.getCount();
var record;
for (var i = 0;i < ln; i++) {
record = storeConfig.store.getAt(i);
if (record.get(storeConfig.valueField) == value) {
return record.get(storeConfig.DisplayField);
}
}
}
