我已经创建了一个动态生成表单的脚本,但是我在加载嵌套模型的数据时遇到了问题.我已经尝试加载整个记录,我已经尝试加载每个子商店,但都不起作用.
我已经完成了使用form.load(),但是从我的理解需要代理连接,并且还需要将json数据存储在’data’数组中.
有没有人对我如何处理这个问题有任何建议？

更新
对不起,我可能没说得很清楚.我在将商店数据加载到表单字段时遇到问题.对于静态的形式我通常使用loadRecord到嵌套模型加载到一种形式,但在这种情况下,所有的字段嵌套在自己的小模型,所以会有每个嵌套模型数值装入与loadRecord自己的领域呢？
HeaderModel存储字段集信息.
ColumnModel的目的是创建将围绕一组字段的容器,用于样式目的.它只创建两列字段.
FieldModel存储特定于字段的属性和数据.
这是响应json数据的一个例子……
{
"HeaderSequence":1,
"Columns":[{
"ColumnWidth":0.5,"Fields":[
{"XType":"textfield","FieldLabel":"FieldA","Name":"NameA","Data":"A","FieldSpecify":true},
{"XType":"textfield","FieldLabel":"FieldB","Name":"NameA","Data":"B","FieldSpecify":true}]
},{
"ColumnWidth":0.5,"Fields":[
{"XType":"textfield","FieldLabel":"FieldA2","Name":"NameA2","Data":"A2","FieldSpecify":true},
{"XType":"textfield","FieldLabel":"FieldB2","Name":"NameB2","Data":"B2","FieldSpecify":true}]
}
]
}
谢谢
解决方法:
我已经弄清楚如何将嵌套模型加载到表单中.我们不能简单地使用load或loadRecord,因为默认情况下该方法尝试获取模型的数据并遍历数据对象并调用setValues.
我要做的是手动获取基本表单元素并自己调用setValues来分配值.
// loop through each field store to load the data into the form by field id
Ext.each(record.ColumnsStore.data.items, function(item) {
Ext.each(item.FieldsStore.data.items, function(fields) {
form.getForm().setValues([{ id: fields.data['Id'], value: fields.data['DisplayName'] }]);
});
});
要跟进这一点,还需要设置自定义提交处理程序.
在商店同步之前,它会遍历商店并设置要存储的提交值.
// define form submit button
var submitButton = new Ext.widget({
xtype: 'toolbar',
dock: 'bottom',
items:[{
xtype: 'button',
text: 'Save',
handler: function(button) {
// get basic form for button
var basic = button.up('form').form;
// get form submit values
var formSubmitValues = basic.getValues();
// get header store
var store = Ext.StoreMgr.get('HeaderStore');
// loop through each field store and update the data values by id from the form
store.each(function(record) {
Ext.each(record.ColumnsStore.data.items, function(item) {
Ext.each(item.FieldsStore.data.items, function(fields) {
fields.data['Data'] = formSubmitValues[fields.data['Id']];
});
});
// mark the record as dirty to be sync
record.dirty = true;
});
// sync store object with the database
store.sync();
}
}]
});
