• How to move something from a virtual dpad on-screen

  - by Kriegalex

  Hello everyone, I've started a little game, and so far I'm moving a little guy with onKeyDown() and the DPAD from Android Emulator. Now what I want to do is to add 4 buttons on the screen (like in a GAMEBOY emulator for example) and these buttons should move my little guy. With a clickListener and onClick() (or touchListener and onTouch()), it's ok for one move but how to do if I want that my little guy continues moving when I stay clicked on the button ??? Buttons are enough or should I make a 4 arrows soft keyboard or anything else ?? Thanks

• Progressbar: Force element.innerHTML update before javascript sort call

  - by maras

  Hi, what is the best practice for this scenario: 1) User clicks "Sort huge javascript array" 2) Browser shows "Sorting..." through element.innerHTML="Sorting" 3) Browser sorts huge javascript array (100% CPU for several seconds) while displaying "Sorting..." message. 4) Browser shows result. Pseudo code: ... <a href="#" onclick="sortHugeArray();return false">Sort huge array</a> ... function sortHugeArray(){ document.getElementById("progress").innerHTML="Sorting..."; ...do huge sort ... ...render result... document.getElementById("progress").innerHTML=result; } When i do that this way, browser never shows "Sorting...", it freezes browser for several seconds and shows result without noticing user... Thank you for advice.

• Passing Data from Usercontrol to controller

  - by nitinkhanna

  Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

• Multiple storages using localStorage

  - by Blondie

  Hey, Is it possible that the same name used can have many different values stored separately and to be shown in a list? e.g. function save() { var inputfield = document.getElementById('field').innerHTML; localStorage['justified'] = inputfield; } <input type="text" id="field" onclick="save();" /> Everytime someone enters something in the input field, and click on save, the localstorage will only save the value in the same name, however, does this conflict the way storage are saved, like being replaced with the latest input value? Also, is there anyway to prevent clearing the localstorage when clearing the cache? Thanks.

• ASP.Net - Gridview row selection and effects

  - by Clint

  I'm using the following code in attempt to allow the user to select a gridview row by clicking anywhere on the row (plus mouse over and out) effects. The code doesn't seem to be applied on rowdatabound and I can't break into the event. (It is wired). The control is in a usercontrol, that lives in a content page, which has a masterpage. protected void gvOrderTypes_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gvOrdTypes = (GridView)sender; //check the item being bound is actually a DataRow, if it is, //wire up the required html events and attach the relevant JavaScripts if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "javascript:setMouseOverColor(this);"; e.Row.Attributes["onmouseout"] = "javascript:setMouseOutColor(this);"; e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(gvOrdTypes, "Select$" + e.Row.RowIndex); } }

• Trigger button click with JavaScript on Enter key in Text Box

  - by ziondreams

  I have one text input and one button (see below). How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box? There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the enter key to click this specific button if it is pressed from within this one text box, nothing else. <input type="text" id="txtSearch" /> <input type="button" id="btnSearch" value="Search" onclick="doSomething();" /> Update: I'd like to accept my own answer below, but since that is now allowed I will accept the next best solution.
