问题 I've run into an issue, that in my opinion is not supposed to be so hard, but at this point 've been cliking through tutorials for hours, without finding results - which have then eventually led me here. I have a page, with images layed out in a grid. on the top of the page there's a header and in the bottom, there's a footer. at this point text, in block-colors, appears in the footer, when an element in the grid is hovered. What I wish to archieve now, is that the text-color of the header

问题 I have a menu on the left column of my site and when the links are clicked, various divs show/hide in the center column of the site. Works fine (jquery and html code below). The issue is that when the divs are loading in the center column, the jquery is animating--the right column slides over to the left column (hiding the center) and then slides back over to the left. I've tried tweaking the hide and fadeIn functions, but can't stop the animation. I want to know how to stop this animation

问题 I have this program that can make collapsibles dynamically, the user can then input content into the collapsible they select (click). When the user adds content to a specific collapsible I'm trying to store the users inputs in an array in local storage. I was trying to do this like so: When the user makes a new collapsible a new array is created with it: function addElement() { /*add closable and it's title*/ //make new array for closables content: contentArray = new Array(); contentArray.id

问题 I found that this works sporadically, but usually doesn't work at all. $(window).unload(function() { $.ajax ({ url: "script.php", type: "POST", data: { value: value } }); }); Setting the async to false (i.e. 'async' : false ) does get around the problem and executes the php script every time. But depending on the script, it can freeze the browser up for a while. Is there a good way of sending data to a php script and having the server execute it without the user waiting for a response? EDIT -
