• In JavaScript can I make a "click" event fire programmatically for a file input element?

  - by gregory.bell

  I'd like to make a click event fire on an <input type="file"> tag programmatically. Just calling click() doesn't seem to do anything or at least it doesn't pop up a file selection dialog. I've been experimenting with capturing events using listeners and redirecting the event, but I haven't been able to get that to actually perform the event like someone clicked on it.

• How do I trap a double-click event on a ListView that has no items?

  - by Brad Younie

  In my C# app, I have a ListView on a Form. I want the user to be able to double-click on a section of the ListView when no items are selected in order to pop up a "New Item" dialog.

• Why the parent page get refreshed when I click the link to open thickbox-styled form?

  - by user333205

  Hi, all: I'm using Thickbox 3.1 to show signup form. The form content comes from jquery ajax post. The jquery lib is of version 1.4.2. I placed a "signup" link into a div area, which is a part of my other large pages, and the whole content of that div area is ajax+posted from my server. To make thickbox can work in my above arangement, I have modified the thickbox code a little like that: //add thickbox to href & area elements that have a class of .thickbox function tb_init(domChunk){ $(domChunk).live('click', function(){ var t = this.title || this.name || null; var a = this.href || this.alt; var g = this.rel || false; tb_show(t,a,g); this.blur(); return false; });} This modification is the only change against the original version. Beacause the "signup" link is placed in ajaxed content, so I Use live instead of binding the click event directly. When I tested on my pc, the thickbox works well. I can see the signup form quickly, without feeling the content of the parent page(here, is the other large pages) get refreshed. But after transmiting my site files into VHost, when I click the "signup" link, the signup form get presented very slowly. The large pages get refreshed evidently, because the borwser(ie6) are reloading images from server incessantly. These images are set as background images in CSS files. I think that's because the slow connection of network. But why the parent pages get refreshed? and why the browser reloads those images one more time? Havn't those images been placed in local computer's disk? Is there one way to stop that reloadding? Because the signup form can't get displayed sometimes due to slow connection of network. To verified the question, you can access http://www.juliantec.info/track-the-source.html and click the second link in left grey area, that is the "signup" link mentioned above. Thinks!

• Does single or double quote matter in str_ireplace in PHP ?

  - by Richards

  Hi, I've to replace newline (\n) with & in a string so that the received data could be parsed with parse_str() into array. The thing is that when I put \n in single quote it somehow turns out as to be replaced with a space: str_ireplace(array('&', '+', '\n'), array('', '', '&'), $response) "id=1 name=name gender=gender age=age friends=friends" But when I put \n in double quotes then it works just fine: str_ireplace(array('&', '+', "\n"), array('', '', '&'), $response) "id=1&name=name&gender=gender&age=age&friends=friends" Why is that so?

  - by Alex Mcp

  I'm working through a book exercise to generate some random serial number, and here's my function: NSString *randomSerialNumber = [NSString stringWithFormat:@"%c%c%c%c%c", '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10]; This works and has an output like: 2J6X7.

• Is it allowed to call a remote web page during a click event?

  - by Blankman

  Is JavaScript allowed to call a remote web page during a click event? When viewing the click in firebug, the call turns red (i.e. error) but I can't see the error because the page redirects. So is it allowed to call a remote website (in my case, its a 1x1 image using a standard url like http://www.example.com/becon).

• How to change the default "double click" action of a web service in a class library (VS2010)?

  - by JL

  I have a web service defined as follows, residing in a class library: [WebService(Namespace = "http://comp.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class SendingItems_new : System.Web.Services.WebService When I double click it, instead of going to code view, it shows the design view. I NEVER use design view, so how can I get it to open up code view instead, its very annoying having to flick from design view each time. Thank you

• Scala type conversion error, need help!

  - by Mansoor Ashraf

  Hello I am getting a weird error when trying to use a Java map in Scala. This is the snippet of code val value:Double = map.get(name) if (value eq null) map.put(name, time) else map.put(name, value + time) the map is defined as val map=new ConcurrentHashMap[String,Double] and this is the error I am getting error: type mismatch; found : Double required: ?{val eq: ?} Note that implicit conversions are not applicable because they are ambiguous: both method double2Double in object Predef of type (Double)java.lang.Double and method doubleWrapper in object Predef of type (Double)scala.runtime.RichDouble are possible conversion functions from Double to ?{val eq: ?} if (value eq null) map.put(name, time) I am new to Scala so I am having a hard time parsing the stacktrace. Any help would be appreciated
