检测放大Firefox [英] Detect Zoom in Firefox
问题描述
我想检测浏览器是否放大或缩小(不要真正关心的值,但我认为它将需要在决策过程中找到)。我已经阅读了很多关于这个话题的其他SO的帖子,但没有一个解决方案给定工作在FF(虽然有一个IE7 / 8和chrome解决方案)。
哦,我不能使用闪存,所以闪存解决方案是没有问题的。
编辑:我必须能够在初始页面加载时检测到这一点。
现代版本的FireFox现在可以执行以下操作:
DPR = window.devicePixelRatio;
/ pre>
if(DPR< = 0.999 || DPR> = 1.001){
//用户放大或缩小
}
I want to detect if the browser is zoomed in or out (don't really care to know the value, but I assume it will need to be found anyway in the decision process). I have read a lot of other SO posts on the topic, but none of the solutions given work on FF (although there is an IE7/8 and chrome solution).
Oh, and I can't use flash, so the flash solution is out of the question.
Edit: And I must be able to detect this on the initial page load
解决方案With modern versions of FireFox, you can now do the following:
DPR = window.devicePixelRatio; if ( DPR <= 0.999 || DPR >= 1.001 ){ // User has zoomed in or zoomed out }
