Bind element and its children in jQuery

由 走远了吗. 提交于 2019-12-10 09:19:30
问题 I'd like to bind an event to an element and its children. What is the best way to do this? $(element).bind('click', function(event) { doSomething(); }); 回答1: $(element).bind('click', function(event) { doSomething(); }).children().bind("click",function(event){ // code to handle children click here event.stopPropagation(); // if you don't want event to bubble up }); 回答2: The code you have will do just that. Look in the event's target field to find out which actual child node saw the event. 来源：

Kill bash script foreground children when a signal comes

由 南笙酒味 提交于 2019-12-10 01:24:04
问题 I am wrapping a fastcgi app in a bash script like this: #!/bin/bash # stuff ./fastcgi_bin # stuff As bash only executes traps for signals when the foreground script ends I can't just kill -TERM scriptpid because the fastcgi app will be kept alive. I've tried sending the binary to the background: #!/bin/bash # stuff ./fastcgi_bin & PID=$! trap "kill $PID" TERM # stuff But if I do it like this, apparently the stdin and stdout aren't properly redirected because it does not connect with lighttpds

Which HTML elements can't contain child nodes?

由 本秂侑毒 提交于 2019-12-08 15:13:36
问题 I've been looking for an exhaustive list, but can't find one anywhere. To avoid having to trawl through the specs, does anyone know what they are (and I suppose a complementary list of elements that can contain children would be useful too). And how much does this list vary between XHTML 1 and HTML5? 回答1: You can find a list of void elements (elements that cannot have any child conents) in the HTML5 spec. With the exception of the new elements introduced in HTML5, the list of void elements in

问题 I am creating a ReactJS Component with an unknown number of children and ancestors, and when a certain event occurs on one of the ancestors I the parent component should know of it. my first approach is to use redux and send the child component with a redux action, and then main parent componetnts will be alerted and will check if the Componetnt sent was one of its ancestors. but, can a parent reactJS component know in someway if another component is one of its ancestors? 回答1: The parent can

jQuery's multiple selector + find() vs children()

由 落花浮王杯 提交于 2019-12-08 03:02:20
问题 <select id="select1"> <option value="11">11</option> <option value="12">12</option> </select> <select id="select2"> <option value="21">21</option> <option value="22">22</option> </select>​ Behavior of the find() and the children() methods: find() : $('#select1, #select2').find('option:not(:first)').remove();​​​​​​ Works as expected: select1 has only option 11 and select2 has only option 21 children() : $('#select1, #select2').children('option:not(:first)').remove(); Works weirdly: select1 has

Android Development: How To Get All EditText Children of a ViewGroup?

由 徘徊边缘 提交于 2019-12-08 01:31:58
问题 Basically, I have a LinearLayout that holds a random amount of horizontal LinearLayouts, and in each of the horizontal LinearLayouts there's a TextView and an EditText. I want to be able to get the value of each EditText children of the master LinearLayout. Sorry if it's confusing, I'm no good at explaining things! Could I just set the same ID for each of the EditTexts then use findViewById, or would that only return the first instance of an EditText? Thanks, Alex. 回答1: You would need to call

Javascript Get Child Element by Name

由 一笑奈何 提交于 2019-12-07 15:37:53
问题 I'm passing a var el into a function. el contains previously grabbed element (using getElementById) and when I console.log el in the function I get the following: The problem comes in when I try to grab an element inside of the el using: el.getElementsByName('fname'); I get the error: Uncaught TypeError: Object #<HTMLDivElement> has no method 'getElementsByName' 回答1: The getElementsByName() API is at the document object level. It's not an HTMLElement method. You could use querySelectorAll()

Adding delay to jquery event on mouseover

由 北慕城南 提交于 2019-12-07 11:41:34
问题 I am trying to add a simple delay to a mouseover event of a child and having difficulties. (Still learning!) This enables me to show the popup after a delay, but shows all of them simultaneously: onmouseover='setTimeout(function() { $(\".skinnyPopup\").show(); }, 600)' and this works to show only the popup I want with no delay: onmouseover='$(this).children(\".skinnyPopup\").show()' but the combination does not: onmouseover='setTimeout(function() { $(this).children(\".skinnyPopup\").show(); }
