问题 What does this code refer too? queryString: function() { //some code } I tested it in the WebConsole (Firefox) but it wouldn't execute, so I'm thinking that it isn't equivalent to function queryString() {} . So what is it exactly? 回答1: You are missing some code there, but I assume its part of an object declaration like this: var obj = { queryString: function() { //some code } }; obj.queryString(); It assigns a function as a property of an object literal. It would be equivalent to this: var

'If' statement and the colon

问题 Here is an interesting piece of code that my fellow team members were just having a slightly heated discussion about... Dim fred As Integer If True Then fred = 5 : fred = 3 : fred = 6 Else fred = 4 : fred = 2 : fred = 1 After executing the above code snippet, what is the value of fred ? Try not to cheat and debug the code. This is a highly contrived code example that started out as an example of using the colon with an If statement, but then someone decided to take it upon themselves to

Selecting an ID with a colon in it with jQuery

由 牧云@^-^@ 提交于 2019-11-27 01:56:57
I'm working on a pre-written module for a site, and I need to target an element with the id test:two . Now, this element has a colon in it, so jQuery is presumably and understandably seeing the 'two' as a pseudo class. Is there any way of targeting this element with jQuery? Also, changing the ID is not possible. Believe me, if I could I would. I've put together an example: $('#test').css('background','red'); $(document.getElementById('test:two')).css('background','blue'); $('#test:two').css('background','green'); <script src="//code.jquery.com/jquery-1.6.3.js"></script> <div id="test">test<

How does MATLAB's colon operator work?

由 孤街醉人 提交于 2019-11-26 21:50:49
问题 As noted in this answer by Sam Roberts and this other answer by gnovice, MATLAB's colon operator ( start:step:stop ) creates a vector of values in a different way that linspace does. In particular, Sam Roberts states: The colon operator adds increments to the starting point, and subtracts decrements from the end point to reach a middle point. In this way, it ensures that the output vector is as symmetric as possible. However, offical documentation about this from The MathWorks has been

Using a colon (:) in a url with ASP.NET/IIS

由 只愿长相守 提交于 2019-11-26 17:46:14
问题 I'm implementing a custom controller in ASP.NET MVC and really want to be able to use a colon in the urls, so that I can identify class/column names and their values, like so: http://example.com/user:chaiguy ...but apparently ASP.NET or IIS doesn't allow colons in urls. I did some digging and apparently it's considered a security issue, but , I'm using MVC and am handling all url paths manually (just treating them as strings), and not relating them to the file system, so I'm pretty sure this

How to get a file in Windows with a colon in the filename?

I am getting errors from customers who are uploading files with a colon in the file name, i.e. C:/uploads/test : doc.html I assume that some Unix or Linux system is generating the file but I'm not sure how the users are saving them with the invalid filename. I have coded a piece that should rename the document on upload. My problem is that I can't test it because I can't get a file on Windows that has a colon in the filename. I found a very similar character to a colon, "꞉" it is a unicode character called a Modifier Letter Colon. This has no space like the fullwidth colon and is pretty much

What does the colon (:) operator do?

由 不羁的心 提交于 2019-11-26 17:02:14
Apparently a colon is used in multiple ways in Java. Would anyone mind explaining what it does? For instance here: String cardString = ""; for (PlayingCard c : this.list) // <-- { cardString += c + "\n"; } How would you write this for-each loop a different way so as to not incorporate the : ? There are several places colon is used in Java code: 1) Jump-out label ( Tutorial ): label: for (int i = 0; i < x; i++) { for (int j = 0; j < i; j++) { if (something(i, j)) break label; // jumps out of the i loop } } // i.e. jumps to here 2) Ternary condition ( Tutorial ): int a = (b < 4)? 7: 8; // if b <

Vectorizing the Notion of Colon (:) - values between two vectors in MATLAB

由 邮差的信 提交于 2019-11-26 09:56:15
问题 I have two vectors, idx1 and idx2 , and I want to obtain the values between them. If idx1 and idx2 were numbers and not vectors, I could do that the following way: idx1=1; idx2=5; values=idx1:idx2 % Result % values = % % 1 2 3 4 5 But in my case, idx1 and idx2 are vectors of variable length. For example, for length=2: idx1=[5,9]; idx2=[9 11]; Can I use the colon operator to directly obtain the values in between? This is, something similar to the following: values = [5 6 7 8 9 9 10 11] I know
