Expression to match jsonobject based of value

[Kurukshetran]

{
    "userName": "test"
    "customer": {
		"mode": "BANK",
		"modeDetails": {
		    "accountNo": "12345678901001",
			"walletId": "11324354@paypal"
		}
	}
}

I am using jsonpath to select accountNo if mode="BANK" or else if mode=WALLET then walletId should be selected. I tried expression $.customer.modeDetails[$.customer.mode=='BANK'].accountNo but it doesn't work. Please help me on this.

Please, at least provide a valid JSON (you're missing a , after "test"):

{
   "userName" : "test",
   "customer" : {
      "mode" : "BANK",
      "modeDetails" : {
         "accountNo" : "12345678901001",
         "walletId" : "11324354@paypal"
      }
   }
}

and

{
   "userName" : "test2",
   "customer" : {
      "mode" : "WALLET",
      "modeDetails" : {
         "accountNo" : "123124124123",
         "walletId" : "somethingelse@notpaypal"
      }
   }
}

How about:

$.customer[?(@.mode=="BANK")].modeDetails.accountNo

or

$.customer[?(@.mode=="WALLET")].modeDetails.walletId
