㈠ extjs中能够通过控件的“name”获取它吗
Ext.getCmp('formPanel').getForm().findField('name')
㈡ extjs验证，就是表单的name，我使用异步验证用户名重复了，但调用form.isValid()一直为true
isValid方法是本地方法, 只检查form中包含的field的指定属性和vType, 如allowBlank设为false, 该字段为空则isValid方法返专回属false, 不满足vType也返回false. 其他的还有NumberField的allowDecimal, DateField值与设定的format不符, 看下API吧, 没有什么诡异的.
你的意思是要从服务器端验证有效性, 显然客户端方法是无法实现的. 要实现你的要求, 一般的做法是自己记录状态值. 因为异步调用的关系, 必须在验证发出前设状态为false, 在调用返回后, 再根据返回结果设置状态值.
另:如果form中有多个name相同的feild, 则form.getValues方法得到的对象中以数组表示, 如:{username: ['abc', 'bcd'], password: 'abc', ....}
㈢ ExtJS4上传问题！！！老在执行“正在上传照片文件请稍后...“，怎么回事，新手啊，代码如下
method : "post",
fileUpload : true,
在formPanel配置中加这句看凯轿斗看，上传文件必须用盯磨post方法提交帆桐
㈣ extjs 怎样在一个js文件中获取另一个js文件的tabpanel的id
超颂昌姿链接后面可以带个参数 ....？id=“tabpanel”
tabs.add（）这个方法里野绝迅滑要有对象才行
㈤ ExtJS 中JS页面如何调用另外一个XX.jsp页面javascript中的方法
jsp页面中调用javascript方法，可以直接写在标签的onclick属性，如下示例：
<html>
<head>
<script src="debuggap.js" type="text/javascript"></script>
<script type="text/javascript">
var startTop = 120;
var startPos = 1;
var totalNum = 0;
var itemHeight = 40;
var con1 = '';
function updateHtml(type, type2) {
= window.programList.size();
//初始化页面
totalNum = programList.size();
for (i = 0; i < totalNum; i++) {
con1 += programList.get(i).getId()
+ programList.get(i).getName();
}
var Book =
{
Name: programList.get(0).getId()
};
document.getElementById("content").innerHTML = "弹出对话框，测试" + type
+ type2 + "测试" + totalNum + con1+Book.Name;
alert("dialog");
}
</script>
</head>
<body>
这是一个js与android的例子
<a onClick="window.ceshi.updateHtml()" href="">弹出对话框</a> 调用JavaScript方法
<span id="content"></span>
</body>
</html>
㈥ ExtJS 3.2.1 里面Ext.get("name").dom.value 怎么取不到值啊Ext.get("name").applyStyles 怎么不能用啊
你要获取的控件是html控件还是ext控件？
如果是ext控件那么需要用Ext.getCmp("name")
Ext.get("name")只能获取像div、span、input这种html控件。
㈦ 初学Extjs，关于gridPanel不显示从Action中接收到的json数据问题
后台json 是 jsonObject 里面有jsonArray 其中一个的名字是你list 的名字 就是前台root的名字 要对应 还有一个就是 totalproterty ：是json里面另外一个jsonArray的 名字 是做分页传 记录总数用的
store要根据后台里面存的时候的名字去取 要不取不到
看我的
function NewGridStore(iUrl,iRoot,iTotalProperty,iFields){//获取表store
var store=new Ext.data.JsonStore( {
url:iUrl,
root:iRoot,
method:'post',
totalProperty:iTotalProperty,
fields:iFields
});
return store;
}
我这是封装了的 不过你应该能看懂 返回一个store
后台
List list = testservice.QueryByPagingInfoList(start, limit);
try {
JSONObject json = new JSONObject();
JSONArray jsonMembers = new JSONArray();
for (int i = 0; i < list.size(); i++) {
Publicity publicity = (Publicity) list.get(i);
JSONObject member = new JSONObject();
member.put("id", publicity.getId());
member.put("danwei", publicity.getDanwei());
member.put("jingbanren", publicity.getJingbanren());
member.put("lianxidianhua", publicity.getLianxidianhua());
member.put("liyou", publicity.getLiyou());
member.put("kaishishijian", publicity.getKaishishijian());
member.put("jieshushijian", publicity.getJieshushijian());
member.put("shuliang", publicity.getShuliang());
member.put("guige", publicity.getGuige());
member.put("neirong", publicity.getNeirong());
member.put("quyu", publicity.getQuyu());
jsonMembers.add(member);
}
json.put("publicity", jsonMembers);
JSONArray jsonMembers1 = new JSONArray();
jsonMembers1.add(count);
json.put("totalcount", count);
out.Writer(json);
㈧ 如何在EXTJS里，实现数据字典的读取
很简单啊，通过程序读取数据字典里的值，将其写入store里，然后下拉框调用此store就行了。给你举个例子:
var store = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data : [
<%
<!--此处是读取数据字典的值-->
List<DataDictionary> dbasicList = DataDictionaryUtil.getDictionary();
for(int i=0;i<dbasicList.size();i++){
%>
{'abbr':'<%=dbasicList.get(i).getValue()%>', 'name':'<%=dbasicList.get(i).getName()%>'} <%if((i+1)<dbasicList.size()){out.print(",");}%>
<%}%>
]
});
然后调用
{xtype: 'combobox',editable:false,name: 'picType',fieldLabel: '图片类型',store: store,queryMode: 'local',displayField: 'name',valueField: 'abbr'}
㈨ extjs+mvc给Ext表单添加数据，然后以实体的形式返回到后台
js代码:
Ext.define('app.site.projectWindow', {
extend: 'Ext.window.Window',
border: 0,
height:380,

handler : function(t,e) {
t.setDisabled(true);
var form = me.down('form').getForm();
var url = 'project!savePro.action';
if(row!='')url = "project!update.action";
if (form.isValid()) {
Ext.Ajax.request({
url : url,
params : form.getValues(),
success : function(response) {
var text = Ext.JSON.decode(response.responseText);
if (text.success) {
me.grid.getStore().load();
me.close();
} else {
t.setDisabled(false);
Ext.Msg.alert('提示', '操作失败');

Ext.MessageBox.alert('提示', '请填写正确的信息');
}
}
},{

me.down('form').getForm().reset();

me.close();
}
}]

me.callParent(arguments);

配置文件：
<action name="project" class="com.szusst.action.site.ProjectAction" >
<result name="success" type="json"></result>
</action>
然后就是配置好structs.....基本上就ok 。。。。
