我正在尝试创建一个10x10图像的网格.这些是从javascript(对象)加载并使用onload方法将其添加到画布.添加工作,但画布图像似乎调整大小.currentSizes.cellSize的结果是80.然而,即使drawImage参数的宽度和高度值为80,所以添加的图像似乎大于80定义的图像.
我的目标是将画布游戏构建为jQuery插件.我想显示一个带有岛屿的javascript动态创建的网格(就像网络浏览器征服类型的游戏一样).所以我想创建一个100%宽度(和高度)的画布,其中javascript动态测量每个单元格(10x10)的大小.
所以我有以下内容:
for( var i = 0 ; i < totalTiles ; i++ ) {
// go to first column in next row
if( x >= 10 ) {
x = x - 10;
y = y + 1;
}
// build the world
tiles[i] = new Image();
tiles[i].x = x;
tiles[i].y = y;
tiles[i].towidth = currentSizes.cellSize;
tiles[i].toheight = currentSizes.cellSize;
tiles[i].coordx = ( x * currentSizes.cellSize );
tiles[i].coordy = ( y * currentSizes.cellSize );
//tiles[i].onload = function() { canvas2d.drawImage( tiles[i] , 0 , 0 ); }
//tiles[i].onLoad = dibaMethods.drawTile( tiles[i] , ( x * currentSizes.cellSize ) , ( y * currentSizes.cellSize ) , canvas2d );
tiles[i].src = "/images/world/tiles/card5.png";
lastIndex = i;
console.log( "looping at: " + i + " with x/y: " + x + "/" + y + " and coordinates: " + tiles[i].coordx + "/" + tiles[i].coordy );
x++;
}
console.log( "Canvas tiles entered, loaded on DOM load, tiles added: " + tiles.length );
tiles[lastIndex].onload = function() {
for( var i = 0; i < totalTiles ; i++ ) {
canvas2d.drawImage( tiles[i] , tiles[i].coordx , tiles[i].coordy );
//canvas2d.drawImage( tiles[i] , tiles[i].coordx , tiles[i].coordy , tiles[i].towidth , tiles[i].toheight );
}
}

任何建议都非常感谢!如果问题需要详细说明,请评论!
该问题源自没有width或height属性的canvas元素.
在编辑html以包含这些属性并删除样式表条目后,它最终起作用.
所以底线,总是向canvas元素添加width和height属性.
