wie man Filter von web3.js richtig verwendet

Ich möchte die Blocknummer basierend auf dem Transaktionshash vom Filter erhalten, aber wenn ich die folgenden Codes zu meinem Projekt hinzufüge, fand ich es seltsam, weil es das Geld manchmal automatisch zweimal überweist und manchmal muss ich ein zweites Mal überweisen, um sehen Sie, wie es den Transaktionshash zurückgibt.

Außerdem bekomme ich die Blocknummer nicht zurück in den Filter. Was ist falsch ?

function TransferTest() {
    alert("START TO TRANSFER")
    var Web3 = require('web3');
    var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
    var abiArray=[
        {"constant":true,"inputs":[],"name":"minter","outputs":
            [{"name":"","type":"address"}],"payable":false,"type":"function"},
        {"constant":true,"inputs":[{"name":"","type":"address"}],"name":"balances","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},
        {"constant":false,"inputs":[{"name":"receiver","type":"address"},{"name":"amount","type":"uint256"}],"name":"mint","outputs":[],"payable":false,"type":"function"},
        {"constant":false,"inputs":[{"name":"receiver","type":"address"},{"name":"amount","type":"uint256"}],"name":"send","outputs":[],"payable":false,"type":"function"},{"inputs":[],"payable":false,"type":"constructor"},{"anonymous":false,"inputs":[{"indexed":false,"name":"from","type":"address"},{"indexed":false,"name":"to","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Sent","type":"event"}
    ];
    var object=web3.eth.getTransactionReceipt("0x327fa3ecb7f9312119201995714c6c94a92accfa1643810b2bd3ee6c4f3a038e");
    var conAddress=object.contractAddress;
    var Mycontract=web3.eth.contract(abiArray);
    var MyConIns=Mycontract.at(conAddress);
    var uAddress=document.getElementById("uAddress").value;
    var tarAddress=document.getElementById("tarAddress").value;
    var AKamount=document.getElementById("AKamount").value;
    var success=web3.personal.unlockAccount(uAddress,"carochan123");
    alert(success);
    MyConIns.send(tarAddress,AKamount,{from:uAddress});var filter=web3.eth.filter("pending");
    filter.watch(function(error, result){
        if (!error)
            alert("monitor");
            alert(result);
        var block = web3.eth.getBlock(result, true);
        alert(block.number);
    });

    alert(MyConIns.balances(tarAddress));//50,150,170,260,270,300,320,330,360,370,380,390,410,420
    alert(MyConIns.balances(uAddress));
