Question

你可以帮我找出我遇到这些错误的原因

    TypeError: Error #2007: 
    Parameter text must be non-null.
    at flash.text::TextField/set text()
    at Perdigana_Scene3_fla::MainTimeline/completeHandler()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at flash.net::URLLoader/onComplete()

这是我在AS3.0中的代码

import flash.net.URLVariables;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.events.Event;
import flash.events.MouseEvent;

//hide processing text
processing_mc.visible = false;

var variables:URLVariables = new URLVariables  ;

//build submit button
var varSend:URLRequest = new URLRequest("form_parse.php");
varSend.method = URLRequestMethod.POST;
varSend.data = variables;

//Build the loading variables
var varLoader:URLLoader = new URLLoader  ;
varLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader.addEventListener(Event.COMPLETE, completeHandler);

//handler for the PHP Script completion and status;
function completeHandler(event:Event):void
{
    //remove processing clip
    processing_mc.visible = false;
    name_txt.text = "";
    password_txt.text = "";
    email_txt.text = "";

    //Load the response from php
    status_txt.text = event.target.data.return_msg;

}

//Add event listener for submit button
submit_btn.addEventListener(MouseEvent.CLICK, ValidateAndSend);

//function ValidateAndSend;
function ValidateAndSend(event:MouseEvent):void
{

    //validate fields
    if (! name_txt.length)
    {
        status_txt.text = "Please enter your username";
    }
    else if (name_txt.length<=5)
    {
        status_txt.text = "Username must be at least 6 characters";
    }
    else if (password_txt.length<=5)
    {
        status_txt.text = "Password must be at least 6 characters";
    }
    else if (!password_txt.length)
    {
        status_txt.text = "Please enter your password";
    }
    else if (!email_txt.length)
    {
        status_txt.text = "Please enter your email";
    }
    else
    {
        //send the data to PHP
        processing_mc.visible = true;

        //ready the variables in the form for sending
        variables.userName = name_txt.text;
        variables.userPassword = password_txt.text;
        variables.userEmail = email_txt.text;

        //send the data to PHP now
        varLoader.load(varSend);

    }
}

当我在ActionScript 3.0场景中按下提交按钮时，它会输出上面提到的错误请帮助！..提前致谢：）

您应该在发送之前将变量设置为 varSend ：

varSend.data = variables;
varLoader.load(varSend);

需要帮助 - Actionscript 3 - PHP
