JQuery可以使用jQuery.browser方法来判断浏览器类型,返回值可以为::safari、opera、msie、mozilla。若返回值为msie说明浏览器是ie。 JQuery可以使用jQuery.browser方法来判断浏览器类型,返回值可以为::safari、opera、msie、mozilla。 当然有时候我们还需要区分版本 这就要用到 jQuery.browser.version 示例: function JudgeBroswer() { if($.browser.msie) { alert("this is msie!"); //IE } else if($.browser.safari) { alert("this is safari!"); //Safari } else if($.browser.mozilla) { alert("this is mozilla!"); //Firefox } else if($.browser.opera) { alert("this is opera"); //Opera } }   JQuery 源码: var userAgent = navigator.userAgent.toLowerCase(); // Figure out what browser is being used jQuery.browser

CSS Dynamic Navigation with Hover - How Do I make it work in iOS Safari?

半世苍凉 提交于 2020-01-30 23:14:58
问题 In my site I use a CSS only dynamic menu. This is fine in desktop browsers, but not on iOS (iphone, ipad, etc) because the touch interface does not support the :hover selector. My question is: what is the best way of supporting this on iOS? (Ideally either by patching with some CSS, or Javascript that will make the existing code work, rather than doing the whole thing over just to support iOS) My html looks like this <ul id="nav"> <li> Item 1 <ul> <li><a href=''>sub nav 1.1</a></li> <li><a

(PHP) How to detect that user's computer/browser is in Dark Mode?

↘锁芯ラ 提交于 2020-01-30 09:01:06
问题 Lately I am updating my software to support dark mode, in response to research that looking at a paper-white background display is bad for the eyes and for sleep rhythms. Is there a way to detect from PHP that a user's browser and/or OS are set to Dark Mode? How about detecting that it is set to nighttime mode (reduction of blue colors)? 回答1: Since PHP executes on the server without any knowledge of the client, there is no direct way of finding this out. If it is possible to detect the color

问题 I have a web app. I'm trying to disable/prevent the scrolling that occurs when you focus on different form inputs (i.e. the scrolling that occurs as you advance through input elements in a form). I've already disabled scrolling with this: <script type="text/javascript"> $(document).ready(function() { document.ontouchmove = function(e){ e.preventDefault(); } }); </script> To add a little more info - I have a few "slides" that my page consists of. Each are 768x1024 and they are "stacked" on the

问题 I want to catch the mouse leaving a select box with the code below. In Chrome this works great, but in Safari the event fires also when moving from the box to the options inside. How can I get the onmouseleave event to fire only when leaving the select element ? thx! var s=document.getElementById("myselect"); s.onmouseleave=function(e) { alert("mouseleave"); } <select id="myselect" size=4> <option>first</option> <option>second</option> <option>third</option> <option>forth</option> </select>
