我正在使用EaselJS,出於某種原因,我的畫布並未將圖像顯示爲背景,即使這是教程如何操作。我的HTML文件是這樣:畫布不顯示背景?
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Requiescat in Pace</title>
...lots of .js imports for EaselJS
<script type="text/javascript" src="RIPwitheasel.js"></script>
<style>
canvas {
position: absolute;
left: 0;
right: 0;
top: 10%;
padding-left: 0;
padding-right: 0;
margin-left: auto;
margin-right: auto;
display: block;
width: 800px;
background: transparent;
}
</style>
<link rel="stylesheet" type="text/css" href="style_2.css">

<body onload="init()">
<font color = white>
<img alt = "full screen bg img" src = "images/backgrounds/pagebackground.jpg" id = "full-screen-background-image"/>
<div style="position: relative">
<h1 style="position: fixed; width:100%; text-align: center"> <strong> Requiescat In Pace </strong> </h1>
<p style = "text-align: center"> Prototype 1 </p>
</div>
<form action="" style = "position: fixed; top: 0; width: 100% text-align: center" >
<input type="button" value="Donate!!!">
</form>
<div style="position: relative">
<p style="position: fixed; bottom: 0; width:100%; text-align: center"> Credits: To be added</p>
</div>
<canvas id="gameCanvas" width="1000" height="736">
Your browser does not support canvas. Please try again with a different browser.
</canvas>
</font>
</body>
</html>
而且我RIPwitheasel.js是這樣的:
var stage;
function init()
{
var canvas = document.getElementById("gameCanvas");
stage = new createjs.Stage(canvas);
var background = new createjs.Bitmap("images/backgrounds/grass-tiled.png");
stage.addChild(background);
createjs.Ticker.setFPS(60);
stage.update();
}
function tick()
{
stage.update();
}
它是什麼,定義不正確?所有頁面都正確顯示,但畫布不顯示圖像。我在js文件的瀏覽器控制檯中得到零運行時錯誤。
編輯:我只是意識到,如果我使用.jpg文件而不是.png文件,它會加載它。爲什麼是這樣?
我使用PNG文件,第一次,也不會加載它,它加載後完美 –
