阅读更多关于 Is there any way to make onbeforeunload work in Opera?

问题 I know, that Opera doesnt support JS onbeforeunload message and will not support it. But is there any way to make it work somehow? Or maybe some jQuery plugins can make it work and let script know if window is going to close? I found only way to make onclick for every a tag, but this is not the complete solution. 回答1: Upgrade to Opera 15. onbeforeunload is now supported in that version because they moved to the WebKit engine. It is still not supported in 12.x because that version and all

Detect left mouse button press

阅读更多关于 Detect left mouse button press

I hate this mess with the mouse buttons created by W3C an MS! I want to know if the left mouse button is pressed when I get a mousedown event. I use this code // Return true if evt carries left mouse button press function detectLeftButton(evt) { // W3C if (window.event == null) { return (evt.button == 0) } // IE else { return (evt.button == 1); } } However, it does not work in Opera and Chrome, because it so happens that window.event exists there too. So what do I do? I have some browser detection, but we all know it cannot be relied upon with all the masking some browsers do lately. How do I

Selenium WebDriver and Opera Driver

问题 I would like to run my Selenium WebDriver tests on Opera, but when I had a look at the Opera driver at Selenium HQ and GitHub page, it says: Opera Driver requires Opera 12.x and older versions Note that OperaDriver is only compatible with Presto-based Operas up until 12.16. Blink-based Operas (15 and onwards) are not supported. Opera is now up to version 22.0, so far beyond the maximum supported version of 12. So, my questions are: - If there is no Opera driver for Selenium, then how does one

How can I zoom an HTML element in Firefox and Opera? The zoom property is working in IE, Google Chrome and Safari, but it’s not working in Firefox and Opera. Is there any method for adding this property to Firefox and Opera? Mubeen Try this code, this’ll work: -moz-transform: scale(2); You can refer to this .

The result of this is if you take a div with width/height = 100% nested inside of another div, with fixed size, if you apply zoom,
