click

The engine I use calls the jquery tabs.js script to handle the tab functions. Problem is that anytime the tabs are at the top of the page and you click on a link, they quickly scroll back down towards the bottom of the page. I've been trying to solve this problem for hours and all solutions point to similar answers, but none work for me. $.fn.tabs = function() { var selector = this; this.each(function() { var obj = $(this); $(obj.attr('href')).hide(); $(obj).click(function() { $(selector).removeClass('selected'); $(selector).each(function(i, element) { $($(element).attr('href')).hide(); }); $

I have an IBAction of when the button is clicked to change my view. How can I handle multiple clicks for example if I click the button a second time to cause another action? Or do I need to delete the button after it has been clicked and then create a new one in its place? If so how do I handle the click event? You can check the clickCount of the mouseDown event: if ([event clickCount] > 1) { // ... do double-click action } else { // ... do single-click action } 来源： https://stackoverflow.com/questions/8997522/nsbutton-multiple-clicks

I'm new here. I'm french so maybe my english is not very good, sorry for that. I'm a beginner in Android development, I got to create an app for finish my study. I have an activity number 1 called VoeuxActivity.java with 8 buttons (and 8 TextViews), they are all VISIBLEs at the beginning, when an user click on one of them button change by INVISIBLE (user can't see the button after clicked on it), when I quit the app and I come back again on my app, the button is always invisible thanks to the SharedPreferences and a member of this forum. But I want now when I clicked on this button named

I only want a method to activate if the pixel that is clicked is white. How would I implement this? Trying to look for a method that returns the colour at a coord, but I can't find one. Depends. If you have got a BufferedImage (or some other Image) you can use its getRGB methods (or getRaster().getPixel ). If you haven't, you can use JPanel's createImage methods and use the returned image to get the pixel data. 来源： https://stackoverflow.com/questions/2623351/getting-the-colour-of-where-you-have-clicked-on-a-jpanel

I have the following code : HTML: <input type='text' class='a' /> <div class='inst' tag='a'></div> <input type='text' class='b' /> <div class='inst' tag='b'></div> <input type='text' class='c' /> <div class='inst' tag='c'></div> JS: $(function() { $('.inst').click(function() { alert($(this).attr('tag') + ' clicked'); }); $('[type=text]').focus(function() { show_inst($(this).attr('class')); }).blur(function() { //hide_inst($(this).attr('class')); }); function show_inst(tag) { $('div.inst[tag=' + tag + ']').html(tag + ' instructions'); } function hide_inst(tag) { $('div.inst[tag=' + tag + ']')

Let us assume that I have a page with a CAPTCHA image. I want to let the user try to enter the code for three times, otherwise he is not allowed to do it anymore. How can I keep track of the number of times the "Confirm" button has been clicked. The "Confirm" button has to perform a postback to the server every time it is clicked. Using JavaScript is not good since if the user reloads the page, the counter would be set to zero. How can this be done please? This should be pretty straight forward. First set the counter to zero, and then update it on subsequent post backs: if (!this.IsPostBack) {
