我正在Superblocks中开发一个Dapp，它可以将Eht从一个地址转移到另一个地址，因为Superblocks中的教程太少了。 我的智能合约代码：
contract Transfer {
address owner ;
function Transfer() public {
owner = msg.sender;
}
function transferTokens (address add) payable public {
add.transfer(msg.value);
}
function getBalance () public returns ( uint){
return add.balance;
}
}
我的js。文件代码：
function waitForReceipt (txHash , cb){
alert("wait for receipt function");
web3_instance.eth.getTransactionReceipt(txHash, function(error, receipt){
if (error){
alert(error);
}
else if (receipt != null){
alert("receipt arrived successful");
cb(receipt);
}
else (setTimeout(function(){
alert(" timeout function ");
waitForReceipt(txHash, cb);
}, 5000));
});
}
function transfer (){
alert("transfer function ");
let val = parseInt($("#numOfTokens").val());
let Address = $("#address").val();
instance.transferTokens.sendTransaction(Address ,{from: accounts[0],
gas:100000, value: val}, function(error, result){
if(error){
alert("error");
}
else{
instance.getBalance(function (err, result){
if(!err){
alert(result);
}
})
alert("transaction success, sending txhash to wait for receipt
function ");
waitForReceipt(result, function(receipt){
alert("passed receipt trough cb function to wfr function ");
if(receipt.status === "0x1"){
}
else {
alert("receipt error...");
}
});
}
});
}
$(document).ready(function () {
init(function () {
});
$("#submit").click (function(){
transfer();
});
});
})(Contracts['Transfer']);
我输入的地址没有得到我想转移到该地址的金额，有人收到建议吗？
