1、 表單中的文件框瀏覽按鈕和text框在IE下顯示錯位,解決方法:
採用textfield,將其input設爲file即可,filefiled在IE下不適用,其他瀏覽器沒問題
2、 Panel中的按鈕位置,可以通過Panel的buttonAlign屬性來配置
3、 Ext中組件的間距可以通過配置組件的style來實現,如:
style: {
marginBottom: '10px',//距底部高度
marginLeft:'10px',//距左邊寬度
marginRight:'50px'//距右邊寬度
}
4、 JsonStore獲取數據時,在需要model時,需要導入高版本的data.model,ext2.2中沒有這個js文件,然後按照高版本的model定義方法定義即可。如:導入ext4.0de model
Ext.define('User', {
extend: 'Ext.data.Model',
fields: [
{name:'id',type:'int'},
{name: 'text', type: 'string'}
]
});
var store1 = new Ext.data.JsonStore({
storeId: 'myStore',
model: User,
pageSize:4,
start:0,
proxy: {
type: 'ajax',
url: 'showDepartments.action',
reader: {
type: 'json',
root: 'results',
totalProperty : 'totalCount'
}
},
//alternatively,a Ext.data.Model name can be given (see Ext.data.Store for an example)
autoLoad: true
});
Model也可以直接通過配置store的fields屬性來實現
5、 grid的行編輯
var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor:1,
autoCancel: false
});
在grid中加入:plugins: [rowEditing]
要給編輯綁定事件,需在rowediting或者panel中綁定事件,如編輯完成事件:grid.on("edit",function(editor,e){//yourcode});
6、 Ext.form提交問題
如果包含有combobox,必須設置hiddenName,不然後臺獲取到的是顯示的文本。
如果含有datefield,需加上format:'Y-m-d',方便後臺獲取。
在struts中如果前臺提交的數據和後臺接收數據部匹配,表單就會提交失敗,出現諸如:編譯錯誤等…
7、datefield時間控件在IE8下面顯示不全,如圖:
這是2.2未對IE8支持,調用如下代碼即可:
Ext.override(Ext.menu.Menu, {//解決2.2時間控件在IE8下顯示不全的問題
autoWidth : function() {
var el = this.el, ul = this.ul;
if (!el) {
return;
}
var w = this.width;
if (w) {
el.setWidth(w);
} else if (Ext.isIE && !Ext.isIE8) {
el.setWidth(this.minWidth);
var t = el.dom.offsetWidth;
el.setWidth(ul.getWidth() + el.getFrameWidth("lr"));
}
}
});
8、時間格式問題
獲取時間控件的值,但一般結果是:這種格式,可以採用時間格式轉換函數轉換,如value爲時間控件獲取到的值,通過value.format(‘Y-m-d’)等就可以轉換,該轉化的結果爲:
9、可編輯表格的問題
點擊可編輯表格出現表格整體行左移
未編輯之前
編輯之後
解決辦法:
Ext.override(Ext.grid.GridView,{//解決可編輯表格中點擊後出現行左移
initTemplates : function(){

加入該代碼即可
10、動態下拉框問題
new Ext.form.ComboBox({
fieldLabel :"部門",
name : "departmentId",
hiddenName : "departmentId",
store : departmentStore,
displayField : 'departmentName',
valueField : 'id',
mode:'remote',
emptyText : "請選擇",
editable:false,
triggerAction:'all' //必須配置此項,否則不會加載數據,代表點擊下拉要出發的動作默認爲query
})
11、可編輯表格中的時間問題
後臺返回時應將時間處理一下
JsonConfig config = new JsonConfig();
config.setIgnoreDefaultExcludes(false);
config.setCycleDetectionStrategy(CycleDetectionStrategy.LENIENT);
config.registerJsonValueProcessor(Date.class,newDateJsonValueProcessor("yyyy-MM-dd"));
DateJsonValueProcessor類的代碼如下:
package util;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import net.sf.json.JsonConfig;
import net.sf.json.processors.JsonValueProcessor;
public class DateJsonValueProcessor implements JsonValueProcessor {
public static final String Default_DATE_PATTERN ="yyyy-MM-dd";
private DateFormat dateFormat ;
public DateJsonValueProcessor(StringdatePattern){
try{
dateFormat = new SimpleDateFormat(datePattern);
}catch(Exception e ){
dateFormat = new SimpleDateFormat(Default_DATE_PATTERN);
}
}
public Object processArrayValue(Object value, JsonConfig jsonConfig) {
return process(value);
}
public Object processObjectValue(String key, Object value,
JsonConfig jsonConfig) {
return process(value);
}
private Object process(Object value){
return dateFormat.format((Date)value);
}
}
這樣可以將時間以”YYYY-MM-dd”的形式返回,在表格中顯示時,如果不使用renderer處理,那麼顯示的時候正常,但是時間控件編輯後的格式就不對如圖:
顯示:
編輯時:
時間控件選擇後:
如果直接加上renderer處理時間格式:會出現NAN-NAN-NAN
正確處理方法:
renderer:function(v){//兼顧處理時間顯示和控件選擇的
if(v instanceof Date)
return new Date(v).format('Y-m-d');
return v;
}
11、右鍵菜單的圖標錯位(IE)
解決辦法:加入css
.ext-ie .x-menu-item-icon {left: -24px; top: 0px;}
.ext-strict .x-menu-item-icon {left: 3px; top: 3px;}
.ext-ie6 .x-menu-item-icon {left: -24px; top: 0px;}
