如果声明放错了地方

问题描述 投票:0回答:2

为了对TweenMax进行一些测试,我正在做一个简单的“抓颜色”游戏,但是看起来我在我的代码中做了一些错误,因为一切都很好,但是一个if语句应该结束游戏。我想问题不在于换色器本身,而在于我放置if语句的地方。我对编程很陌生,所以我很有可能犯了一些愚蠢的错误。

您可以在这里查看整个页面:https://codepen.io/IvanRoselli/pen/vbqjoo

这是我使用的Javascript

var colorCircle = document.getElementById('circle');
var startBtn = document.getElementById('start-btn');
var catchBtn = document.getElementById('catch-btn');
var mainTitle = document.getElementById('main-title');
var colorChange = new TimelineMax({repeat: -1});
var circleBackgroundColor = document.getElementById('circle').style.backgroundColor;
var colorCircle = document.getElementById('circle');
var startBtn = document.getElementById('start-btn');
var catchBtn = document.getElementById('catch-btn');
var mainTitle = document.getElementById('main-title');
var colorChange = new TimelineMax({repeat: -1});
var circleBackgroundColor = 
document.getElementById('circle').style.backgroundColor;

function playPause(){
    colorChange.paused(!colorChange.paused()); 
}

function getIt(){
     $('#catch-btn').click(function(){
        if(circleBackgroundColor === 'blue'){
            mainTitle.innerHTML = "YOU WON!";
            return;
        } else {
            mainTitle.innerHTML = "Try again pressing CATCH"; 
            playPause();
        }
    })
}

function startGame(){
    getIt();
    $('#start-btn').css("display", "none");
    $('#catch-btn').css("display", "inline");
    $(colorCircle).css("cursor", "pointer");
    colorChange.from(colorCircle, .5, {backgroundColor: 'orange', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'red', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'pink', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'yellow', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'blue', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'green', ease: SteppedEase.config(1)});
    colorChange.to(colorCircle, .5, {backgroundColor: 'cyan', ease: SteppedEase.config(1)});


};


$('#start-btn').click(function() {
    startGame();
});

基本上H1应该在“You Won”之间改变,如果你抓住蓝色或“再试一次”其他颜色。

在此先感谢您的帮助和建议。

问题是它给rgb值和app也没有停止赢也改变了if条件。

if((document.getElementById('circle').style.backgroundColor) === 'rgb(0, 0, 255)'){
            mainTitle.innerHTML = "YOU WON!";
          playPause();
            return;
        } else {
            mainTitle.innerHTML = "Try again pressing CATCH"; 
            playPause();
        }

请看下面的功能。您必须在onclick事件期间捕获元素的颜色,这意味着在单击按钮时捕获颜色,而在您的情况下,颜色在加载期间被捕获并且永远不会更改。我已经使用rgb格式进行条件检查。

function getIt(){
    $('#catch-btn').click(function(){
       circleBackgroundColor = document.getElementById('circle').style.backgroundColor;
        if(circleBackgroundColor == 'rgb(0, 0, 255)'){
            mainTitle.innerHTML = "YOU WON!";
            return;
        } else {
            mainTitle.innerHTML = "Try again pressing CATCH"; 
            playPause();
        }
    })
}
