What's the difference between addEventListener and onclick ? var h = document.getElementById("a"); h.onclick = dothing1; h.addEventListener("click", dothing2); The code above resides together in a separate .js file, and they both work perfectly. Both are correct, but none of them are "best" per se, and there may be a reason the developer chose to use both approaches. Event Lis
addEventListener和onclick什么区别？ var h = document.getElementById("a"); h.onclick = dothing1; h.addEventListener("click", dothing2); 上面的代码一起存放在一个单独的.js文件中，并且它们都可以很好地工作。 两者都是正确的，但它们本身都不是“最好的”，开发人员可能会选择使用这两种方法。 事件监听器（addEventListener和IE的attachEvent） 早期版本的Internet Explorer与其他几乎所有浏览器的JavaScript都
I have made some custom functionality to the CKEditor. In short, it shows a div tag with 5 links, for Small, Medium, Large X-Large and Original size. When I click the links, it changes the SRC attribute of the image to the correct size. It works, but it doesn't persist back to the editor. It's like the Image i get through the click event target, is not part of the Source code. How
我已经为CKEditor制作了一些自定义功能。 总之，它显示了一个带有5个链接的div标签，用于小型，中型，大型X大型和原始大小。 当我点击链接时，它会将图像的SRC属性更改为正确的大小。 它可以工作，但不会持续到编辑器。 这就像我通过点击事件目标获得的图像，不是源代码的一部分。 如何在编辑器中操作元素时更改源代码？ 我的代码如下所示： $(target).ckeditor(function (editor) { $(this.document.$).bind("cli
As you can see a blocking kind of function like alert() produce its output not in order when is filled in event queue of Google Chrome's by setTimeout() function, based on this code. for (var i = 1; i <= 6; i++) { (function(index){ setTimeout(function() { alert(index) }, 100); })(i); } Why is that? Is it considered as a Google Chrome's bug? There should be an explanat
正如你所看到的，像alert（）这样的阻塞类型的函数在通过setTimeout（）函数填充Google Chrome的事件队列时根据此代码生成其输出的顺序不正确 。 for (var i = 1; i <= 6; i++) { (function(index){ setTimeout(function() { alert(index) }, 100); })(i); } 这是为什么？ 它是否被视为Google Chrome的错误？ 应该有一个解释。 一般来说，期望在任何特定时刻（比如说，以毫秒为精度）只有一个执行时隙，

I am using an AJAX call to to get the response from the server. I can see that in our logs, server is responding the proper data, eg: " <xmltag> " + result + " </xmltag>" After we get the result we are using below snippet: if (null != result && result.indexOf('<xmltag>') > -1) { var temp = result.split(' '); ppdTime = temp[1]; } Most of the time (almost 9

Is it possible to identify visitors to a site who are running a development browser, like Chrome Canary, using JavaScript? Using the User Agent String, it is obviously possible to check out the version of a browser, but as that increments I assume the dev version eventually becomes the standard version and then eventually a legacy version; so targeting a version number would need constantly up
是否可以使用JavaScript来识别正在运行开发浏览器的网站的访问者，如Chrome Canary？ 使用用户代理字符串，显然可以检查浏览器的版本，但是随着增量的增加，我认为开发版本最终会成为标准版本，最终成为旧版本; 因此定位版本号需要不断更新。 例如，目前这些是Chrome的开发和股票版本： 加纳利（17/07/15） Mozilla / 5.0（Windows NT 6.1; Win64; x64）AppleWebKit / 537.36（KHTML，如Gecko）Chrome / 46.0.2457.0 Safa
