selection

问题 Currently my function looks like that http://jsfiddle.net/tt13/5CxPr/13/ as you see, now when I click one by one multiple rows, it will make them selected. What I want to do is, to select multiple rows by pressing ctrl+left-click and one and only selection with only one - left click (I mean remove previous selected and select last clicked one; just like windows icon selection). How can I modify current code? 回答1: Try this: $(".subject").live('click',function(event) { event.preventDefault();

问题 I have a list of vertices, from which I have to pick a random vertex with probability proportional to deg(v), where deg(v) is a vertex degree. The pseudo code for this operation look like that: Select u ∈ L with probability deg(u) / Sigma ∀v∈L deg(v) Where u is the randomly selected vertex, L is the list of vertices and v is a vertex in L. The problem is that I don't understand how to do it. Can someone explain to me, how to get this random vertex. I would greatly appreciate if someone can

问题 I have two edit text views. If I click first, I need to select first edittext and set to second "00". Like in default android alarm clock. My problem: I have api level 10, so I can't write something like: firstEText.setOnFocusChangeListener(new View.OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { secondEText.setText("00"); } }); If I use firstEText.setOnKeyListener(new View.OnKeyListener() { @Override public void onFocusChange(View v, boolean hasFocus

问题 In Firefox, I can search for text using either CTRL + F [normal search] / [quick search] ' [quick search, links only] I can style user-selected text / links using a:focus a:active ::-moz-selection However the first two seem to apply only to user-selected/focused/activated links (by mouse, or TAB -navigating). ::-moz-selection seems to be applied only to the text I manually selected, not the text that is selected due to incremental search. The incremental search match is highlighted by Firefox

问题 OK, the behavior or my NavigationView works. I click on the settings and it takes me there. I click on my first item, it does what it should. I click on the second item, it does what it should. However, my issue is with the selection state. I will click on an item, and it will not select it. The only selection that works is my Settings menu. When I click on that item, the settings menu will become selected, along with all previous items I clicked on. Scenarios On App Load Go to NavigationView

问题 Why this VBA code ((initial part of a sub) modifies the visible selection in the Word document? I'm not modifying any selection. As per MSDN description: "If you've gotten to the Find object from the Range object, the selection isn't changed when text matching the find criteria is found, but the Range object is redefined. (Taken from: Find Object (Word)) So the following code should just modify the Range, and not affect the selection at all... Sub SelectTarget() Dim MyRange As Range Set

问题 I didn't find any information on this question, and I wonder if it is possible to make NSTableView (or subclass) to select rows by pressing space bar on keyboard, and navigate through rows by pressing up/down keys without the selection being reset. I want to make nstableview to behave like total commander's file panel, if someone used it under windows. And I don't even know where to start. 回答1: You will have to make subclass of the NSTableView class. This is basic example how you could do it.

问题 I am trying to replace some text inside a div using a modal window with a form input but for some reason I can't get it to work on IE11. I've realized that it skips new lines when selecting a piece of text containing a <br> Here is a working example: http://jsfiddle.net/8VdE9/3/ The funny thing is that I am using the same code in a different page and it gets the new lines fine, which makes me think that I am missing something. var isIE11 = !!navigator.userAgent.match(/Trident.*rv\:11\./);

问题 Is there any way to observe changes to the selectedTextRange of a UITextField? I tried observing all UIControlEvents. But changing the selectedTextRange does not trigger a UIControlEvent. Another dead end -- UIKit classes are not KVO compliant. Then there is the UITextFieldTextDidChangeNotification. But that's for changes to the text. Any ideas? 回答1: Subclass UITextField as follows. @interface WJTextField : UITextField @end @protocol WJTextFieldDelegate <UITextFieldDelegate> - (void)

问题 How can I get the characters before AND after the selected text, and then remove them? Or rather, if the selected text is within the characters, remove the surrounding characters, that way if there are any extra spaces the characters will still be removed. For example, when double clicking on the text, it will select the text, but not the backticks before and after. I want to then remove those backticks. I have it where I can add characters to the selection, but when only selecting the text
