我正在使用带有JsonReader的DataStore来填充ComboBox,但是没有将正确的值标记为已选择。
组合框:
{
fieldLabel: 'Business Unit',
xtype:'combo',
width:167,
name: 'business_Unit',
hiddenName: 'businessUnit',
store: businessUnitStore,
displayField: 'buName',
valueField: 'buId',
mode: 'remote',
triggerAction: 'all',
typeAhead: false,
editable: false
}
我在表单中使用了JsonReader。
var leadReader = new Ext.data.JsonReader({
root: 'data',
totalProperty: 'total',
id: 'leadId'
}, [
{name:'title', type: 'string'},
{name:'firstName', type: 'string'},
{name:'lastName', type: 'string'},
{name:'designation', type: 'string'},
{name:'business_Unit', type: 'string', mapping: 'businessUnit.buName'},
]);
这是JSON响应:
{"data":{"leadId":22,"firstName":"fname","lastName":"lname","designation":"President","businessUnit":{"buId":4,"buName":"US","buDescription":""}},"success":true}
我希望在组合框中选择BusinessUnit = US,并且在加载表单时还可以在组合中选择所有其他选项。
editForm.getForm().load({url:fetchUrl, method: 'GET'});
一切正常,但组合中未选择BusinessUnit = US。
答案 0 :(得分:0)
combo上的name字段与json响应中的字段(business_Unit vs businessUnit)不匹配,但我认为BasicForm.load不适用于嵌套对象。加载调用后,您可能需要手动加载它。
editForm.getForm().load({url: fetchUrl, method: 'GET', success: function(form, action) {
var combo = form.findField('business_Unit');
combo.setValue(action.result.data.businessUnit.buiId);
}
});
