Javascript var === 2 && console.log('true'). How does this work?
This (mis)uses the boolean handling of JavaScript; because of the lazy evaluation of expressions, console.log('true') is only run, when someVar === 2 was previously evaluated as true. This behaviour is called Short-circuit evaluation. Other use-cases By the way, this type of coding has legit use cases. My favourite is the...

Change: if(p1 == p2 || p1 == p3 || p1 == p4){ Toast.makeText(getApplicationContext(), p1 + " It's a tie.", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(getApplicationContext(), p1 + " You chose the winner!", Toast.LENGTH_SHORT).show(); } to if(p1 > p2 && p1 > p3 && p1 > p4){ Toast.makeText(getApplicationContext(), p1 + " You chose the...
Create a Triangular Matrix from a Vector performing sequential operations
r,for-loop,matrix,vector,conditional
Using sapply and ifelse : sapply(head(vv[vv>0],-1),function(y)ifelse(vv-y>0,vv-y,NA)) You loop over the positive values (you should also remove the last element), then you extract each value from the original vector. I used ifelse to replace negative values. # [,1] [,2] [,3] [,4] [,5] # [1,] NA NA NA NA NA # [2,]...
Kendo ui grid if else condition
javascript,if-statement,kendo-grid,conditional
You can handle it in grid databound event too.Check this fiddle: http://jsfiddle.net/Sowjanya51/krszen9a/ You can modify the databound instead of looping through all the cell collection if(dataItem.OrderType == 'OrderType20') ...
Searching python lists with loops and conditionals
python,python-2.7,loops,conditional
It is difficult to understand your desired output, but this is my best guess: In [39]: a = [1,1,3,4,4,6] b = [20150602, 20150603, 20150604, 20150605, 20150606, 20150607] c = zip(a, b) print c for i in range(0, len(c)-1): if c[i][0] == c[i+1][0] and c[i+1][1] - c[i][1] <= 3: print c[i]...
Python AND OR statements
python,if-statement,conditional
Unless the output from the first line of code is "ar" or "fr" (or something else not in the if-elif conditions), you are over-writing the opt variable. Consider re-naming the 'new' opt to something else, like follows: opt = child.get('desc') extent = child.get('extent') if opt == 'es': opt2 = "ESP:"...
Passing JSP Parameters, then checking if they exist
java,jsp,parameters,conditional,parameter-passing
Is that all you have in your include.jsp file? If yes, then add this to the top of the file: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> The jsp prefix is predefined but JSTL's c prefix is not. Your server might not recognize <c:if>s as server side tags (because of the missing...
Macro for run-once conditioning
c,if-statement,macros,conditional
I guess you're saying you want the macro to somehow automatically track which bit of your bitmask contains the flag for the current test. You could do it like this: #define CHECKSUM(d) static d checksum_boolean; \ d checksum_mask #define CHECKSUM_START do { checksum_mask = 1; } while (0) #define CHECKSUM_IF...
Bash conditional statement
You are missing a semicolon or a line jump before the then keyword. Beware also that Bash uses > to compare strings, not numbers. For numeric comparison you should be using either -gt or the Bash specific (( arithmetic expression evaluator. For instance: #!/bin/bash MAX=35000000000 if (( $(du -sb ~/MEGA...
C - preprocessors multiple macros
c,gcc,macros,conditional,preprocessor-directive
You can use this syntax: #if defined(PLOT) || defined(GRAPH) ...
SQL Conditional aggregation
sql,oracle,conditional,aggregation
The determination of whether the number should be treated as positive or negative needs to happen inside of your aggregation SUM(). So: select sum(case when type = 1 OR type = 2 then value else - value end) from table t group by year; Because both 1 and 2 are...
Conditional subtraction Part 2
We paste the 'Channel' and substring of 'Hour' column together ('nm1'), concatenate the 'TV1Slope' and 'TV5Slope' vectors ('TV15'), match the 'nm1 vector with names of 'TV15' after removing the 'Slope' substring with sub, and get the corresponding 'TV15' value. Subset the columns with names starting with 'cols' using grep, do...
Thymeleaf compare #locale expression object with string
conditional,locale,thymeleaf,spring-el
This is a issue that I told to the guys of thymeleaf time ago. You need to resolve first the #locale before comparing it with "en". You can do that adding 2 underscore at the beggining and end to the expresion that you want to resolve first. In your case...
.NET use IIF to assign value to different variables
.net,vb.net,conditional,variable-assignment,iif
What you're asking to do would have been possible in a language that supports pointer types (such as C/C++, or C# in unsafe mode) with dereferencing; VB.NET doesn't do that. The best you got to leverage is local variables, reference types, and (perhaps) ByRef. If it's a Class, its instantiation...
One liner conditional, multiple variables and check that all of them are not false?
python,if-statement,conditional,conditional-statements
Use a simple generator expression and all(): if all(d.get(k) for k in keys): Example: keys = ['proxy_host', 'proxy_port', 'proxy_protocol'] if all(settings.get(k) for k in keys): print("Settings good!") else: print("Missing setting!") ...
ng-repeat except value 2
angularjs,conditional,ng-repeat
use ngIf because the ngIf differs from ngShow and ngHide in that ngIf completely removes and recreates the element in the DOM rather than changing its visibility via the display css property. <div ng-repeat="element in data.arrayElement" ng-if="element.val !== 2"> ...
