Question

我有两个元素和它们之间的联系。建立连接后，我为此连接设置参数：

private async void WaitForIncomingMessagesAsync()
{
    var buffer = new byte[8192];
    var stringBuilder = new StringBuilder();
    while (IsRunning)
    {
        using (var responseStream = WebRequest.Create("some url").GetResponse().GetResponseStream())
        {
            int receivedDataCount;
            do
            {
                receivedDataCount = await responseStream.ReadAsync(buffer, 0, buffer.Length);
                if (receivedDataCount != 0)
                {
                    stringBuilder.Append(Encoding.ASCII.GetString(buffer, 0, receivedDataCount));
                }
            } while (receivedDataCount > 0);
        }
        var receivedDataJson = stringBuilder.ToString();
        Array.Clear(buffer, 0, buffer.Length);
        stringBuilder.Clear();
    }
}

一切正常。

如何通过点击按钮以编程方式获取参数'isNo'？

jsPlumb.bind("connection", function(e) {

	........

	jsPlumb.select(e).setParameter('isNo','1');

	........

});

<script>
$( "#getparam" ).on("click", function() {
	// How to get the connection parameter?
});
</script>

OP解决方案。

我用这种方式解决了问题：

var getConn = jsPlumb.getConnections();

if(getConn.length > 0){
	$.each(getConn, function (e,s) {
		var parameters = s.getParameters();
		console.log(parameters.isNo);
	});
}
