refresh

问题 Currently Im following this tutorial http://www.appcoda.com/ios-programming-app-backend-parse/ But I want the tableviewcontroller to be refresh with new data when data from parse.com is update automatically. I don't want the user to always have to pull to refresh. or maybe having time refresh every minute? I heard about reloaddata but how to implement the code? - (id)initWithCoder:(NSCoder *)aCoder { self = [super initWithCoder:aCoder]; if (self) { // The className to query on self

问题 I have a few functions which I load in the ready() event. These basically make a list draggable, and other areas droppable/sortable. Eg. You can drag a clone into multiple areas (lists in divs), and within these multiple areas, you can sort/reorder them (but only within each area). This works perfectly. I have a button which dynamically creates a new area for items to be dropped into, then sorted. It creates the new area perfectly, but you cannot drop items into it, or then even make them

问题 I have a complex xpage with lots of nested custom controls. Everytime I execute a partial refresh it takes over 4 seconds to finish. If I remove the complexity it works just fine and is fast as wished. I put a test on this complex Xpage and even with partial execution mode this simple test takes over 4 seconds to finish. <xp:button value="Label" id="button1"> <xp:eventHandler event="onclick" submit="true" refreshMode="partial" refreshId="refreshPanel" disableValidators="true" execMode=

问题 I have a long-running script using spotipy. After an hour (per the Spotify API), my access token expires. I am catching this successfully, but I don't know where to go from there in regards to actually refreshing the token. I am using the authorization code flow, not client credentials. Here's how I authorize: token = util.prompt_for_user_token(username,scope=scopes,client_id=client_id,client_secret=client_secret, redirect_uri=redirect_uri) sp = spotipy.Spotify(auth=token) All refresh

问题 I have button that gets disabled when you click it but when I refresh the page it should still be disabled. How can I do this? <button onclick="this.disabled = true">Disable</button> 回答1: You should use cookies. Javascript won't preserve page state after page refresh (unless you are doing server side of course): DEMO Code: function setCookie(name, value){ // Set cookie to `namevalue;` // Won't overwrite existing values with different names document.cookie = name + value + ';'; } function

问题 Using jQueryMobile, when I change the contents of a select widget and then call 'refresh' on it, the text of the selected option is not changed. Here's the scenario... The 'select' widget exists in the page div already. When the user goes to that screen, the options are dynamically created based on the button they selected to go to that page.
