Add image to page onclick

由 自古美人都是妖i 提交于 2019-12-11 02:49:18
问题 I want a button to add an image to the current page on each click. For example, the first time you open the page, there is one picture. Then you click the button and the same picture appears on the page and now you have two same pictures. Then you keep on pressing on the button and more and more same pictures appear. This is the code I tried that didn't work: <script type="text/javascript"> function addimage() {<img src="http://bricksplayground.webs.com/brick.PNG" height="50" width="100">} <

BaseExpandableListAdapter - disable onclick for groupitems with no childrens

由 半世苍凉 提交于 2019-12-11 02:47:42
问题 I'm working on implementing an ExpandableListAdapter. Use case: I have group items I want to add to the Expandable list with no children. Problem is that every group item can be clicked on, even if they contain no children. Is there a way to disable/grey out the expandable button to indicate for the user that it contains no children? At the moment I've implemented: public void onGroupExpanded(int groupPosition) { if (!containsChildren(groupPosition)) { Toast.makeText(context, context

问题 I haven't found a proper answer for this yet: Should & (ampersand) be escaped in onclick="..." ? (Or for that matter, in every HTML attribute?) I have tried running both escaped and unescaped tests on jsFiddle and W3C's validator, both are working... http://jsfiddle.net/6LuES <div onclick="if (1==1 && 2==2) alert('hello there');">Without escape</div> <div onclick="if (1==1 && 2==2) alert('hello there');">With escape</div> http://validator.w3.org/#validate_by_input <!DOCTYPE html> <html lang=

Android ListFragment update/refresh and onItemClick

由 岁酱吖の 提交于 2019-12-11 02:28:00
问题 I´ve a problem in my Android Project. It´s a music track player, which shows each track in a ListFragment. Every item has got a Bitmap, where an oscilloscope is drawn on the bitmaps canvas. The items in the Listfragment are refreshed periodically. This is done via notifyDataSetChanged(); I also want to mute one track when I click on the item, but the onItemClick event doesn´t get fired every time. Only sometimes. Can anyone explain this to me? What am I doing wrong here? It works perfect

How to get link URL on onClick in a QWebView?

由 与世无争的帅哥 提交于 2019-12-11 02:19:23
问题 How do I get a link's URL when clicking on the link? If I have a link in the A tag, it's simple: just connect linkClicked(const QUrl&) signal to specific slot. But if I have a table with an "onClick" event on its cell (generated html: "<td onClick=\"window.location.href='" + link_ + "';\" ......blahblahblah"), it's not working. Why? 回答1: As it's name suggests, the linkClicked signal is only emitted whenever a link is activated. But you can intercept all navigation requests by reimplementing

How can I pass a variable through an onclick event when javascript is creating the html?

由 喜你入骨 提交于 2019-12-11 02:18:33
问题 My javascript creates a line of html. That html has an onclick event call to openSingle() . I need to pass a variable into that function. onclick="openSingle('+findID+')" When I check the dev panel when it runs, i get onclick="openSingle(WP0100200-3a)" The only thing that is missing is the quotes around the id . But if i try to code in the quotes, it breaks the html and then puts everything out of order. Here is my line of code and all the pertaining variables. var iconImage = '<img src="../.

Getting text at clicked location in an HTML element

由 拜拜、爱过 提交于 2019-12-11 01:39:39
问题 I have a div element containing some text. When the user clicks a word inside that div I'd like to highlight just that word. In order to do this I need to know what character position in the text the click occurred at, so I can then locate nearby whitespace and insert some formatting around the word. Finding out where the click occurred within the text is the trick here. Is that kind of thing possible? 回答1: If your page is auto-generated, you might consider pre-processing the page by putting

How is the order of event listeners in javascript determined?

由 六月ゝ 毕业季﹏ 提交于 2019-12-11 00:58:00
问题 Suppose there is a div which contains a link ( a href) and there are three event listeners - on-click- 1) for the entire page, 2) on div 3) a tag. If the user clicks on the a tag, how are the listeners triggered? What is the order of them being registered? 回答1: Essentially, it depends. There are 2 phases for events, Capturing (happens first), which goes document down, and Bubbling which goes element up. JS can do both, which is why when creating a custom Event listened you have the third
