toggle

问题 That just could be very simple, but it's about 2AM and getting quite sleepy :) I have short script which "slideToggle" div from being non-displayed. $('#cmnt_add').click(function () { $('.dark_div_add').slideToggle(1100); }); Is there a chance to make it workout once, so if non-displayed DIV is opened, clicking same link won't do a thing? Thank you in advance! 回答1: Use .one() : $('#cmnt_add').one("click", function () { $('.dark_div_add').slideToggle(1100); }); From jQuery's documentation:

问题 I am trying to set up a group of keybinds that I can toggle on and off with a single button press but haven't been able to find any examples anywhere.

问题 So I've got a div that should expand to reveal a list when toggled. The before and after states can be seen here http://reversl.net/box/ but what do I need to add to my styling to make this happen? I'd like to use css transitions for added effect. I'm not worried about browser compatibility because it's just for learning purposes. Any tips? <div class="box"><img src="http://www.placehold.it/250x300" alt="" /> <div class="section progress"> <h4> <a href="#">Div Before</a> </h4> <div class=

问题 So what I want to do is to make a dynamic little script for selecting countys and then cities. Well I have all the countys and citys in a mysql database. If I choose a county in a <select> tag the cities related to the county should appear in the next <select> tag. So basically maybe I could do something like $(document).ready(function() { $('.county').click(function(){ $(this.name).toggle(); }); }); where the option for countys maybe look something like this: <option value="This County" name

问题 I know that there is the possibility of Matlab of pausing a Matlab function or script by using input() thus when I have a for-loop and want to pause it every iteration: for i = 1:N reply = input(sprintf('Pausing in iteration %d! Continue with Enter!', i), 's'); % Calculations end but how to get the following working: Usually it runs without pausing (as if the input() wouldn't be there) but when the user does something (perhaps press a key, a button, or something similar in matlab), the script

问题 Looking for a way to implement a "full-screen" action reversible with double tap but I did not succeed! More in detail, there are 2 UIView : - topViewContainer - bottomViewContainer When I double-tap on the superview, the view "bottomViewContainer" extends to full-screen, and I re-double tap, the view returns to its original size. It should work in portrait mode and Landscape Mode! This is what I've done until now: -(void)handleDoubleTap:(UITapGestureRecognizer *)sender { if ([[UIApplication

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago .

问题 Building a tree menu with jQuery, and I want it to be accessible, so I'm using aria attributes. What I want to do is toggle the "aria-expanded" attribute from true to false on click/enter. I've tried this, but it's obviously not correct: $(this).closest('ul').find('> li.tree-parent').toggleAttr( 'aria-expanded', 'true false' ); 回答1: You can use .attr() to manually write the toggle logic $(this).closest('ul').find('> li.tree-parent').attr('aria-expanded', function (i, attr) { return attr ==

问题 I know, it's not supported by IE, but I found a cool script online that someone was generous enough to provide for free, but I can't figure out why it's not working. I've been staring at this for hours, please point me in the right direction! My code: <script language="javascript" type="text/javascript" src="getbyclass.js"></script> <script type="text/javascript" language="javascript"> function editToggle(toggle){ if (toggle == "off"){ getElementsByClassName("editp").style.display ="none";
