Question

EXTJS中text中怎么得到后台回来数据，用if判断，combo值等于2003,就取出address=2003这条记录中number值

{"total":0,"number":[{"address":"2003","number":"6.00"},{"address":"2008","number":"20.00"},{"address":"2012","number":"20.00"},{"address":"2013","number":"20.00"},{"address":"2014","number":"20.00"}]}
请贴码

感觉你这说的好乱啊，又是text又是combo的，到底啥玩意儿，如果你这是下拉框的话，不就是valueField与displayField为的设置问题嘛，设置下就可以了，取值嘛getValue或者getRawValue，如果是其他控件事件触发的， 可以对store进行循环遍历啊
