alb*_*rto 5 javascript jquery resize image
考虑到导航栏的可用空间,我创建了此代码以调整照片/图像的大小以适应屏幕.
该脚本将在图像加载和导航点击时触发.
有没有人建议改善这一点并确保浏览器兼容性?
$(document).ready(function(){
$("#photo").load(function(){
resize();
});
$(".navigation img").click(function(){
var imgPath = $(this).attr("src");
$("#photo").attr({ src: imgPath });
resize();
return false;
});
});

resize = function() {
var borderVt=150; //value based on css style. bottom bar + padding of photoContain
var borderHz=40; //value based on css style photoContain padding
$("#photo").css("width", "auto").css("height", "auto"); // Remove existing CSS
$("#photo").removeAttr("width").removeAttr("height"); // Remove HTML attributes
var origSizeW = $("#photo").width();
var origSizeH = $("#photo").height();
var ratioVt=(origSizeW/origSizeH);
var ratioHz=(origSizeH/origSizeW);
var winW = $(window).width();
var winH = $(window).height();
var screenSizeW=Math.round(winW-borderHz);
var screenSizeH=Math.round(winH-borderVt);
if (origSizeW>=origSizeH){
var newHeight = Math.round(screenSizeW*ratioHz);
if (newHeight <= screenSizeH){
$("#photo").css("width", screenSizeW); // Set new width
$("#photo").css("height", newHeight);
}
else{
$("#photo").css("height", screenSizeH);
}
}
else{
$("#photo").css("height", screenSizeH); // Set new height
}
};

我知道这个问题已经过时了,但这里有一个解决方案(虽然我确信OP的工作正常):
这个jQuery插件似乎完全符合您的需求:http: //code.google.com/p/jquery-imagefit-plugin/
如果你在100%高度,100%宽度元素上执行它:http: //www.tutwow.com/htmlcss/quick-tip-css-100-height/
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="http://jquery-imagefit-plugin.googlecode.com/svn/trunk/jquery.imagefit-0.2.js"></script>
<div style="width: 100%; height: 100%">
<img id="h5" src="http://www.w3.org/html/logo/downloads/HTML5_Logo_512.png"/>
</div>
<script>
jQuery('#h5').bind('load', function() {
jQuery('div').imagefit();
});
</script>

尝试使用jQuery-Backgrounder插件.您可以调整它来做您需要的事情.这是一个例子:
<script src="jquery.backgrounder.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
$(function() {
$('#my_background').backgrounder({element : 'body'});
});
</script>
[...]
<div id="my_background"><img src="birthday.jpg" alt="Birthday party" /></div>
