iPhone app getting XML then refreshing it at intervals...

- by user157733

I have an app which gets some data from the web via an XML document. I have this working fine and have followed apples SeismicXML example (uses NSURLRequest etc). I am very new to this so I have to admit that I do not totally understand all the code that gets the XML - but it is working. My problem is that my app may be running for some time so I want to be able to refresh the XML every now and again and check to see if it is different. If it is different I need to update my contents. Basically this means my questions are.... Is there a standard way of doing this? I was thinking of creating a timer to call the function which parses the XML but I can't figure out which function to call. If anyone can give me any pointers or even better examples of this it would be fab. Thanks

Defautlt Contoller in CodeIgniter

- by gregavola

Hello everyone, I am wondering if there is any other configuration options for a default controller. For example - if I have a controller called "site" and I set the default controller in the following file: application/config/routes.php to: $route['default_controller'] = "site"; I should be able to go to http://localhost and that brings up the index(); function in the site controller. However, if I try to do go to http://localhost/index.php/index2 to load the index2(); function I get a 404 error. If i change the URL to http://localhost/index.php/site/index2 it works fine - but I thought already set the default controller. Is there any way around this? Any thoughts?

Beginner C++ Question

- by Donal Rafferty

I have followed the code example here toupper c++ example And implemented it in my own code as follows void CharString::MakeUpper() { char* str[strlen(m_pString)]; int i=0; str[strlen(m_pString)]=m_pString; char* c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } } But this gives me the following compiler error CharString.cpp: In member function 'void CharString::MakeUpper()': CharString.cpp:276: error: invalid conversion from 'char*' to 'int' CharString.cpp:276: error: initializing argument 1of 'int toupper(int)' CharString.cpp: In member function 'void CharString::MakeLower()': This is line 276 putchar (toupper(c)); I understand that toupper is looking for int as a parameter and returns an int also, is that the problem? If so how does the example work?

jQuery: using hover to roll-over multiple images at once.

- by WillKop

I have a small problem, but I'm a bit stumped. I am using the following code to do rollovers on my webpage $("#mylink1 img").hover( function() { this.src = this.src.replace("_off","_on"); }, function() { this.src = this.src.replace("_on","_off"); } ); This works great for individual images, but I would like to roll over one of them and have the the other one change as well. <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_manage_off.gif" /></a> <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_nav2_off.gif" /></a> Any help would be appreciated! Thank you!

Theme the node-create and node-edit template

- by Toxid

I'm using drupal 6. I've managed to make a .tpl file for one content type, that is for images in my image gallery. I did that by adding this code in template.php: function artbasic_theme($existing, $type, $theme, $path) { return array( 'galleryimage_node_form' => array( 'arguments' => array('form' => NULL), 'template' => 'galleryimage_node_form' ) ); } And then I created galleryimage_node_form.tpl.php, and was good to go. Now it happens so that I want to have other template files for the forms of other content types, for example link_contrib_node_form.tpl.php. I've tried a couple of ways to change this function to include more content types, but I can't figure it out. Can anyone help?

Changing cell class on radio button change

- by Nick

Huge thanks for the help in this thread - Click td, select radio button in jQuery But now I'm having trouble that it won't change the class of the cell, even though I have binded the 'change' trigger in jQuery like so: $("td input[type=radio]").bind('change click', function () { $('td').removeClass('selected'); $(this).parent('td').addClass('selected'); }); $("td").click(function () { $('input:radio', this).attr('checked', true); }); Hope that makes sense. If you click the radio button, or move between them using the keyboard, the cell's class changes just fine. However if you trigger this by clicking the cell it doesn't change the class :( Thanks

I dont know where is the error, is there any error in writing the js file? please comment.

Why is order important in moving from tab to tab programmatically (and new in 1.8.10

- by Bruce

Hi folks, Up until I updated to jquery-ui-1.8.10 (already using jQuery 1.5), the following code has worked as expected: case 'baseeditor': $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); $("#prolearn").tabs("select",1); break; case ... The tab is fueled and then focus is moved from tab0 (from where the ajax call is initiated) to tab1. Now, that code won't work, but this version does: case 'baseeditor': $("#prolearn").tabs("select",1); $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); break; case ... Can someone explain the difference - have I just been lucky getting away with my original version? Thanks/Bruce

Getting jQuery to recognise .change() in IE

- by Philip Morton

I'm using jQuery to hide and show elements when a radio button group is altered/clicked. It works fine in browsers like Firefox, but in IE 6 and 7, the action only occurs when the user then clicks somewhere else on the page. To elaborate, when you load the page, everything looks fine. In Firefox, if you click a radio button, one table row is hidden and the other one is shown immediately. However, in IE 6 and 7, you click the radio button and nothing will happen until you click somewhere on the page. Only then does IE redraw the page, hiding and showing the relevant elements. Here's the jQuery I'm using: $(document).ready(function(){ $(".hiddenOnLoad").hide(); $("#viewByOrg").change(function () { $(".visibleOnLoad").show(); $(".hiddenOnLoad").hide(); }); $("#viewByProduct").change(function () { $(".visibleOnLoad").hide(); $(".hiddenOnLoad").show(); }); }); Here's the part of the XHTML that it affects. Apologies if it's not very clean, but the whole page does validate as XHTML 1.0 Strict: <tr> <td>View by:</td> <td> <p> <input type="radio" name="viewBy" id="viewByOrg" value="organisation" checked="checked"/> Organisation </p> <p> <input type="radio" name="viewBy" id="viewByProduct" value="product"/> Product </p> </td> </tr> <tr class="visibleOnLoad"> <td>Organisation:</td> <td> <select name="organisation" id="organisation" multiple="multiple" size="10"> <option value="1">Option 1</option> <option value="2">Option 2</option> </select> </td> </tr> <tr class="hiddenOnLoad"> <td>Product:</td> <td> <select name="product" id="product" multiple="multiple" size="10"> <option value="1">Option 1</option> <option value="2">Option 2</option> </select> </td> </tr> If anyone has any ideas why this is happening and how to fix it, they would be very much appreciated!

Add another class to a div with javascript

- by zac

I have a function that checks the age of a form submission and then returns new content in a div depending on their age. right now I am just using getElementById to replace the html content. BUt I think would work better for me if I could also add a class to a div as well. So for example I have.. if (under certain age) { document.getElementById('hello').innerHTML = "<p>Good Bye</p>"; createCookie('age','not13',0) return false; } else { document.getElementById('hello').innerHTML = "<p>Hello</p>"; return true; } What I would like to do is have everything in a div and if return false then that div disappears and is replaced with other content.. can I get any ideas on a good way to achieve this with pure javascript. I dont want to use jQuery for this particular function.

Problem with jQuery animation

- by Daemon

I have a problem with an animation in jQuery using ajax. On the click of an button (actually an tag), I call a ajax method, and have the following written inside the success parameter: success: function(msg) { $('.ContentsMainRight').children().fadeOut(500, function() { $('.ContentsMainRight').html(msg.d); $('.ContentsMainRight').children().fadeIn(1000); }); }, This have the following result. The contents of a div fade out over 500ms as it's supposed to. Then the html contents of the div are swapped, but then the last part did not work as I hoped. The html returned by the ajax method include some text inside a tag, and a image inside a tag. The result is that the text is automatically displayed instantly with no fadein, but the img that is put fades in over 1 second. Why is the text and image treated differently? -Daemon

How can I delete a row in the view only if the AJAX call & db deletion was successful?

- by user1760663

I have a table where each row has a button for deletion. Actually I delete the row everytime without checking if the ajax call was successfull. How can I achieve that, so that the row will only be deleted if the ajax call was ok. Here is my clickhandler on each row $("body").on('click', ".ui-icon-trash" ,function(){ var $closestTr = $(this).closest('tr'); // This will give the closest tr // If the class element is the child of tr deleteRowFromDB(oTable, closestTr); $closestTr.remove() ; // Will delete that }); And here my ajax call function deleteRowFromDB(oTable, sendallproperty){ var deleteEntryRoute = #{jsRoute @Application.deleteConfigurationEntry() /} console.log("route is: " + deleteEntryRoute.url) $.ajax({ url: deleteEntryRoute.url({id: sendallproperty}), type: deleteEntryRoute.method, data: 'id=' + sendallproperty });
