This is not possible I think. You can only call chaincode functions inside the same channel. The function invokeChaincode uses the same transaction context as the original transaction.
Have a look into <a href="https://github.com/hyperledger-archives/fabric/blob/master/core/chaincode/shim/chaincode.go" rel="nofollow noreferrer">https://github.com/hyperledger-archives/fabric/blob/master/core/chaincode/shim/chaincode.go</a>

<pre><code>// InvokeChaincode locally calls the specified chaincode `Invoke` using the
// same transaction context; that is, chaincode calling chaincode doesn't
// create a new transaction message.
func (stub *ChaincodeStub) InvokeChaincode(chaincodeName string, function string, 
args []string) ([]byte, error) {
return handler.handleInvokeChaincode(chaincodeName, function, args, stub.UUID)
}

// QueryChaincode locally calls the specified chaincode `Query` using the
// same transaction context; that is, chaincode calling chaincode doesn't
// create a new transaction message.
func (stub *ChaincodeStub) QueryChaincode(chaincodeName string, function string, args

You can invoke one chaincode from another by using stub.InvokeChaincode method-

<pre><code>response := stub.InvokeChaincode(chaincodeName, invokeArgs, channelName)
if response.Status != shim.OK {
 return nil
}

return response.Payload
</code></pre>

blocks|key|3266315|text|如果您用javascript或typescript编写链码，您可以使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3266316|const+args+=+[functionName,+...]

If you write your chaincode in javascript or typescript you can use the following code:

<pre><code>const args = [functionName, ...]
const result = await ctx.stub.invokeChaincode(chaincodeName, args, channelName)

return result.payload.toString('utf8')
</code></pre>

I have a network of 3 orgs and two channels.

channelone: org1, org2, chaincode- fabcar

channeltwo: org1, org3, chaincode- fabphone

I want to query chaincode- fabphone using fabcar.
