javascript - Differences between methods of reloading pages -


<पूर्व> window.location.reload () history.go (0) window.location.href = window.location Href

मैंने एक वेबसाइट पर टिप्पणी की है कि इन तरीकों के सभी 3 तरीकों को एक पृष्ठ पुनः लोड करने के लिए इस्तेमाल किया जा सकता है इस पर विश्वास करने के लिए सामग्री नहीं है, मैंने IE8, FF3, और ओपेरा 10 में सभी 3 तरीकों की कोशिश की। मैंने देखा कि फ़ायरफ़ॉक्स ने history.go (0) के लिए एक वास्तविक पुनः लोड के बजाय एक कैश पुनः लोड किया, लेकिन अन्यथा कोई मतभेद नहीं देखा। हालांकि, मैंने सोचा कि मैं यहाँ समुदाय से पूछूंगा कि इन विधियों के बीच वे क्या अंतर रखते थे।

Window.location.reload () और window.location.href = window.location.href के बीच मुख्य अंतर यह है, कि यदि पहले मौजूद है तो POST डेटा फिर से भेज देगा (ब्राउज़र आपको पूछेगा कि क्या आप पृष्ठ को पुनः लोड करना चाहते हैं और पुनः भेजें डेटा), दूसरा यूआरएल यूआरएल को किसी भी POST डेटा की अनदेखी कर देगा।

History.go (0) के बारे में, हम इतिहास वस्तु का उपयोग कर रहे हैं, इसलिए ब्राउज़र संचयित पृष्ठ के कैश्ड संस्करण का उपयोग कर सकते हैं कहीं स्मृति में।

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

I am making my own UITableViewCells with a gradient background. I have worked all the logic and drawing, but the one that I want to fix is ​​"chunky" around the corners of my custom cell: If you have corners, you See what I'm talking about. Here is the code that I am using to generate cells: CGCTXT C = UigRxGroupCertexConnect (); CGColorSpaceRef myColorSpace = CGColorSpaceCreateDeviceRGB (); CGGradientRef myGradient = Zero; CGFloat component [8] = TABLE_CELL_BACKGROUND; CGContextSetStrokeColorWithColor (C, [[UAColor colorWithWhite: 0.7 alpha: 1] CGColor]); CGContextSetLineWidth (C, 2); CGContextSetAllowsAntialiasing (C, Yes); CGContextSetShouldAntialias (C, Yes); CGFloat minx = CGRectGetMinX (RECT), MIDX = CGRactgetMIDX (RECT), MAX x = CGTXxX (RECT); CGFloat miny = CGRectGetMinY (Rect), maxy = CGRectGetMaxY (rect); CGMutablePathRef Path = CGPathCreateMutable (); CGPathMoveToPoint (path, NULL, minx, miny); CGPathAddArcToPoint (default margin of path, NULL, mix, ...

Best practice for URL redirection in ASP.NET web application -

I have an asp page (Default.aspx) that shows the difference between two text files. It has two drop down lists (respectively id = "file1" and "file2" respectively) and a button (id = "submit"). There is also a lexical control with the id "result". The content of the list button is populated based on the files present in the physical application path. Each time the submit button is clicked, I want to give the result of diff / comparison in literal control, so I have an event handler like this: protected Zero Submit_Click (Object Sender, EventArgs e) {Results.First = Comparison Files (File 1. Selected Price, File2.SelectedValue); } The problem with this is that you can not bookmark results of comparison between specific files. To solve this problem, I compare the values ​​of the selected files as a query string for the added URL and made a redirection. And so, the above event handler has been changed to look like this: Protecte...
