jquery-events

I want to check if user changes the value of a textbox. If the user changes the value, then I want to display the changed value in a different textbox. jquery has an event for this, .change() , this event will detect content changes when the textbox looses focus. If you are wanting to detect the change at every keypress, .keyup() and .keydown() might be better suited for your needs. Examples for your intended use: //just change '.change' to '.keyup' or '.keydown' the rest is the same. $('input').change(function() { $('target').val(this.value); }); 来源： https://stackoverflow.com/questions

I need to use inline edit in my application. For this purpose I am using the Jeditable plugin for jQuery. I want to trigger editable mode for an element only when I click on it.

I'm creating a drag and drop image environment, where if you hover over an image, a small menu pops up overtop of it. if you click and drag the image, you can reorder them. The problem I'm having is, I want the hover event to be disabled when you're dragging around. Currently if you drag an image around, it triggers all the hover menus on the other images you hover over. $('ul.imglist li').mousedown( function() { $(this).find('ul') .fadeOut(100); }); // Image actions menu $('ul.imglist li').hover( function() { $(this).find('ul') .css('display', 'none') .fadeIn('fast') .css('display', 'block');

I was asked to implement ctrl+mousewheel event for our page site in order to change image offset on user zoom in or zoom out. I found this old answer Override browsers CTRL+(WHEEL)SCROLL with javascript and I`ve tried to do the same. I downloaded the jQuery Mouse Wheel Plugin for the implementation and here is my code: var isCtrl = false; $(document).on('keydown keyup', function(e) { if (e.which === 17) { isCtrl = e.type === 'keydown' ? true : false; } }).on('mousewheel', function(e, delta) { // `delta` will be the distance that the page would have scrolled; // might be useful for increasing

I have a list of products, where I need to update the innerHTML of a #container dynamically. My question is, if I do something like in this answer: Jquery Remove All Event Handlers Inside Element $("#container").find("*").off(); So, I remove all the event handlers for all the children, and then I update the html: $("#container").html(responseFromAJAX); How will this affect on the performance? I mean, is this a good way, to remove all the old elements and handlers, and clean up memory, or I need to do more? My app is a webshop, so my Users will look around, and update the #container maybe 30-50
