php echo statement if screen is a certain size
提问by Sam Skirrow
I have a series of jQuery scripts on my site that I want to only run if the users screen width is greater than 960px. I know that you can't detect screen size using php but is there a way to create something to this effect:
我的网站上有一系列 jQuery 脚本，我只想在用户屏幕宽度大于 960 像素时运行。我知道您无法使用 php 检测屏幕大小，但有没有办法创建这种效果：
<? php
if [METHOD TO DETECT SCREEN SIZE] > 960px {
echo '<script src="js/nbw-parallax.js" type="text/javascript"></script>';
}
?>

Why not use jQuery?

if( $(window).width() > 960 )

$.ajax({
url: 'js/nbw-parallax.js',
dataType: "script",
success: function() {
//success
}
});
}

PHP is server side and can't grab your screen width and height.
PHP 是服务器端，无法获取您的屏幕宽度和高度。
You have to use javascript.

<?php
if ( stristr($ua, "Mobile" )) {
$DEVICE_TYPE="MOBILE";
}
if (isset($DEVICE_TYPE) and $DEVICE_TYPE=="MOBILE") {
echo '<script src="js/nbw-parallax.js" type="text/javascript"></script>';
}
?>
Here's a link to a more detailed script: PHP Mobile Detect

You can have a javascript that sets a cookie containing the user's screen size. (Sure it won't work on the first request, but every subsequent request will work). Then in php you can get the value of the cookie.
您可以使用 javascript 设置包含用户屏幕大小的 cookie。（当然它不会对第一个请求起作用，但每个后续请求都会起作用）。然后在 php 中你可以得到 cookie 的值。

you will have to use a javascript (or jQuery) function to generate the new script tags depending on the screen size. You will probably find this http://api.jquery.com/jQuery.getScript/helpful.
您将不得不使用 javascript（或 jQuery）函数根据屏幕大小生成新的脚本标签。您可能会发现这个http://api.jquery.com/jQuery.getScript/很有帮助。

you should make the JS to detect the resolution and choose by itself whether it should run some code or not.
您应该让 JS 检测分辨率并自行选择是否应该运行某些代码。
