blur

问题 What are the advantages of using jQuery's $(window).blur(function() { ... }) to attach an event handler versus setting it directly with window.onblur = function() { ... } It seems that the latter is less robust because it only supports one blur handler, and when used with other packages, other code might override the window.blur value with another function. However, couldn't this also happen with the jQuery implementation too, which presumably uses window.blur as its underlying implementation

问题 if($('#this').val().indexOf('4289')){ Do something else Do something. This works only with that 4289 , When I try to add other numbers to be indexed next to it using 'or', it doesn't work. How should I put other number. E.g IndexOf('4289||78843') I want this to check this numbers and if the number in the input field is not one of this, to echo error. Here's more which happens to die when one revisits the field. $('#Zip').blur(function(){ if (($(this).val().indexOf('0860') > -1)||($(this).val(

问题 The constructor of WriteableBitmap class with Windows 8 only takes two arguments: the height and the width of this object. Meanwhile with Silverlight it accepts a BitmapImage object as argument.

问题 Microsoft Edge is not supporting filter: blur(); like it should. If I have an absolute positioned element with filter: blur(); , inputs that appear on top will go nuts, merging with the blur (fun to watch). Here's a Fiddle to show what happens. Works perfectly in Chrome and Firefox, but Edge turns into borderline epileptic. Just click the input and enjoy: https://jsfiddle.net/Cthulhu/3uz0Lpfz/2/ Here's a code example: <style> article { background: url(http://uzebox.org/wiki/images/1/19

问题 Can anyone tell me why sometimes JavaFX displays the content of a TextField with a blur effect on it? It seems to be random and occurs in any of my TextField s. Please see the image attached. 回答1: Focusing on the intermittent rendering artifact mentioned here, the 2 glyph looks like it's been rendered twice, with one copy shifted horizontally relative to the other. Such apparently random anomalies are notoriously difficult to identify. Myriad causes may include incorrect synchronization,

问题 I am trying to blur an image in C# by going through all of the pixels of one image and then creating a new Bitmap with the color of the pixels in the original image divided by the pixel count to create an average color. When I run it, nothing happens. Here's the code: private void blurToolStripMenuItem_Click(object sender, EventArgs e) { Bitmap img = new Bitmap(pictureBox1.Image); Bitmap blurPic = new Bitmap(img.Width, img.Height); Int32 avgR = 0, avgG = 0, avgB = 0; Int32 blurPixelCount = 0;

问题 I know this question has been asked before, but I am trying to put a blur on a map view in my app. Everything I've tried just tints the map including code like this: var darkBlur = UIBlurEffect(style: UIBlurEffectStyle.Dark) var blurView = UIVisualEffectView(effect: darkBlur) blurView.frame = mapView.bounds mapView.addSubview(blurView) Is there a way to actually blur the map? 回答1: Did you try adding blurView to mapView 's superview? Works fine for me in Playground: 来源： https://stackoverflow

问题 I want to use the 'blur' event in the jQuery text plugin. http://jqueryte.com $ ('textarea'). jqte ({ blur: function (elem) { // ID textarea? // Content editor? } }); The function of the blur, I would like to determine the content and the ID of the textarea. Can you help me with an idea? 回答1: Since it doesn't look like the blur event is passing any arguments to the callback you might have to do something like $("textarea").each(function(idx, elem) { $(this).jqte({ blur: function() { console
