parent & child with position fixed, parent overflow:hidden bug

由 我只是一个虾纸丫 提交于 2019-11-26 11:46:52
I don't know if there is an issue, but I was wondering why the overflow:hidden does not function on fixed parent/children element. Here's an example: CSS and HTML: .parent{ position:fixed; overflow:hidden; width:300px; height:300px; background:#555; } .children{ position:fixed; top:200px; left:200px; width:150px; height:150px; background:#333; } <div class="parent"> <div class="children"> </div> </div> Live demo: jsFiddle Because a fixed position element is fixed with respect to the viewport, not another element. Therefore since the viewport isn't cutting it off, the overflow becomes

PHP - Find parent key of array

由 瘦欲@ 提交于 2019-11-26 11:34:58
问题 I\'m trying to find a way to return the value of an array\'s parent key. For example, from the array below I\'d like to find out the parent\'s key where $array[\'id\'] == \"0002\". The parent key is obvious because it\'s defined here (it would be \'products\'), but normally it\'d be dynamic, hence the problem. The \'id\' and value of \'id\' is known though. [0] => Array ( [data] => [id] => 0000 [name] => Swirl [categories] => Array ( [0] => Array ( [id] => 0001 [name] => Whirl [products] =>

问题 I have some list item tags in my jsp. Each list item has some elements inside, including a link (\"a\" tag) called delete. All that I want is to delete the entire list item when I click the link. Here is the structure of my code: $(\"a\").click(function(event) { event.preventDefault(); $(this).parent(\'.li\').remove(); }); <script src=\"https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js\"></script> <li id=\"191\" class=\"li\"> <div class=\"text\">Some text</div> <h4><a href=\

Select parent element of known element in Selenium

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-11-26 06:30:03
问题 I have a certain element that I can select with Selenium 1. Unfortunately I need to click the parent element to get the desired behaviour. The element I can easily locate has attribute unselectable, making it dead for clicking. How do I navigate upwards with XPath? 回答1: There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward. JavaScript: WebElement myElement = driver.findElement(By.id("myDiv")); WebElement parent = (WebElement)

由 假装没事ソ 提交于 2019-11-26 05:55:54
问题 http://jsfiddle.net/S8g4E/ I have a container div with two children. The first child has a given height. How can I make the second child to occupy the \"free space\" of the container div without giving a specific height? In the example, the pink div should occupy also the white space. Similar to this question: How to make div occupy remaining height? But I don\'t want to give position absolute . 回答1: Expanding the #down child to fill the remaining space of #container can be accomplished in

Why does appending a <script> to a dynamically created <iframe> seem to run the script in the parent page?

由 喜你入骨 提交于 2019-11-26 04:41:16
问题 I\'m attempting to create an <iframe> using JavaScript, then append a <script> element to that <iframe>, which I want to run in the context of the <iframe>d document. Unfortunately, it seems I\'m doing something wrong - my JavaScript appears to execute successfully, but the context of the <script> is the parent page, not the <iframe>d document. I also get a 301 Error in Firebug\'s \"Net\" tab when the browser requests iframe_test.js , though it then requests it again (not sure why?)
