在Sencha Touch 2中,我有一个控制器,可以调用自定义' prepopulate'按钮上的方法:
Ext.Ajax.request
({
method: 'GET',
url: myurl, //defined outside
withCredentials: true,
headers:{Authorization : auth},
success: function(response){
var data;
if(response.responseText.length > 0)
data = Ext.JSON.decode(response.responseText.trim());
console.log(data);
var fv = me.getFiscal();
console.log(fv);
fv.prepopulate(data);
Ext.Viewport.animateActiveItem('fiscal', me.getSlideLeftTransition());
},
failure: function(response){
Ext.Msg.alert('Server Error', 'Server down :( please try again later');
}
}
);
查看代码:
prepopulate : function (data) {
var me = this;
var companyTextField = me.down('#fiscalForm').down('#companyTextField');
var vatField = me.down('#fiscalForm').down('#vatField');
var fiscalCodeTextField = me.down('#fiscalForm').down('#fiscalCodeTextField');
var addressTextField = me.down('#fiscalForm').down('#addressTextField');
var cityTextField = me.down('#fiscalForm').down('#cityTextField');
var zipTextField = me.down('#fiscalForm').down('#zipTextField');
var countryTextField = me.down('#fiscalForm').down('#countryTextField');
console.log(vatField);
console.log((data.vat));
if(data){
if(data.company_name)
companyTextField.setValue(data.company_name);
if(data.vat)
vatField.setValue(data.vat);
if(data.fiscal_code)
fiscalCodeTextField.setValue(data.fiscal_code);
if(data.address)
addressTextField.setValue(data.address);
if(data.city)
cityTextField.setValue(data.city);
if(data.zip)
zipTextField.setValue(data.zip);
if(data.country)
countryTextField.setValue(data.country);
}
console.log(vatField);
}
AJAX调用工作正常,并且成功调用prepopulate方法传递从服务器检索的数据。 我尝试使用setValue()初始化TextFields,但表单看起来是全新的'当我用浏览器打开它时 console.log()告诉我,_value私有字段已经正确设置了......我现在正在黑暗中摸索......有什么见解?
提前谢谢你。

正如您所建议的那样,我正确地检索并使用console.log在控制台中显示数据,但是当调用setValue()时,浏览器找不到任何可见字段来修改该值。
到目前为止,解决方案是修改ajax请求,如下所示:
Ext.Ajax.request
({
....
....
success: function(response){
....
Ext.Viewport.animateActiveItem('fiscal', me.getSlideLeftTransition());
//view must be in the viewport before modifying data:
var task = Ext.create('Ext.util.DelayedTask', function () {
var fv = me.getFiscal();
fv.prepopulate(data);
});
task.delay(1000);
.....
....
...
..
