我使用缩放图像以适应父级div的代码,它被称为“aspectcorrect”。 问题发生在移动版本上:我的父div具有100%宽度,并且当用户将屏幕的方向更改为横向时,图像不会调整大小以适应新div的宽度。当屏幕方向发生变化时重新运行javascript函数
当用户改变屏幕的方向时,有一种方法可以重新运行onload事件(缩放图像)?
这是我的网站:www.mcsoftware.com.br/sitemc 我仍在努力。
(要明白我在说什么,打开你的手机,当您更改屏幕方向只需点击“Continuar mesmo assim”导航)
谢谢!
aspectcorrect.js
function ScaleImage(srcwidth, srcheight, targetwidth, targetheight, fLetterBox) {
var result = { width: 0, height: 0, fScaleToTargetWidth: true };
if ((srcwidth <= 0) || (srcheight <= 0) || (targetwidth <= 0) || (targetheight <= 0)) {
return result;
}
// scale to the target width
var scaleX1 = targetwidth;
var scaleY1 = (srcheight * targetwidth)/srcwidth;
// scale to the target height
var scaleX2 = (srcwidth * targetheight)/srcheight;
var scaleY2 = targetheight;
// now figure out which one we should use
var fScaleOnWidth = (scaleX2 > targetwidth);
if (fScaleOnWidth) {
fScaleOnWidth = fLetterBox;
}
else {
fScaleOnWidth = !fLetterBox;
}
if (fScaleOnWidth) {
result.width = Math.floor(scaleX1);
result.height = Math.floor(scaleY1);
result.fScaleToTargetWidth = true;
}
else {
result.width = Math.floor(scaleX2);
result.height = Math.floor(scaleY2);
result.fScaleToTargetWidth = false;
}
result.targetleft = Math.floor((targetwidth - result.width)/2);
result.targettop = Math.floor((targetheight - result.height)/2);
return result;
}
onimageload.js
function OnImageLoad(evt) {
var img = evt.currentTarget;
// what's the size of this image and it's parent
var w = $(img).width();
var h = $(img).height();
var tw = $(img).parent().width();
var th = $(img).parent().height();
// compute the new size and offsets
var result = ScaleImage(w, h, tw, th, false);
// adjust the image coordinates and size
img.width = result.width;
img.height = result.height;
$(img).css("left", result.targetleft);
$(img).css("top", result.targettop);
}
哪里的onload功能发生
<img onload="OnImageLoad(event);" />
