• Javascript Global Variable in Array

  - by user1387727

  My question may be very easy to lots of people, but I am new to Javascript. I really do not know what is wrong with the following codes. var newValue = 1; function getCurrentAmount() { return [newValue,2,3]; } var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); In the above code, the result shown in console is: undefined23 Why is the result not "123"? I am trying to use global variable because I want to increment newValue by 1 each time when the function is called. I want something like the following: var newValue = 1; function getCurrentAmount() { newValue ++; return [newValue,2,3]; } setInterval(function(){ var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); }, 1000); Also, I just tired the following codes and it works as expected. var newValue =1; function test() { newValue ++; return newValue; } console.log(test()); So I think the problem is about the Array. I hope my question is clear enough. Thanks in advance.

• returning values from function or method multiple times by only calling the class once

  - by Sokhrat Sikar

  I have a members.php file that shows my websites members. I echo members name by using foreach method. A method of Members class returns an array, then I use foreach loop in the members.php file to echo the members. I am trying to aovid writing php code in my members.php file. Is there a way to avoid using foreach inside members.php file? For example, is it possible to return value from a method couple of times? (by only calling the object once). Just like how we normally call the functions? This question doesn't make sense, but I am just trying to see if there is a away around this issue?

• Why Use java.lang.reflect.Array For Anything Other Than Array Creation?

  - by dimo414

  Java Class java.lang.reflect.Array provides a set of tools for creating an array dynamically. However in addition to that it has a whole set of methods for accessing (get, set, and length) an array. I don't understand the point of this, since you can (and presumably would) cast your dynamically generated array as an array upon creation, which means you can use the normal array access (bracket notation) functionality. In fact, looking at the source code you can see that is all the class does, cast the array, and throw an exception if the cast fails. So what's the point / usefulness of all of these extra methods?

• C# assign values of array to separate variables in one line

  - by Sarah Vessels

  Can I assign each value in an array to separate variables in one line in C#? Here's an example in Ruby code of what I want: irb(main):001:0> str1, str2 = ["hey", "now"] => ["hey", "now"] irb(main):002:0> str1 => "hey" irb(main):003:0> str2 => "now" I'm not sure if what I'm wanting is possible in C#. Edit: for those suggesting I just assign the strings "hey" and "now" to variables, that's not what I want. Imagine the following: irb(main):004:0> val1, val2 = get_two_values() => ["hey", "now"] irb(main):005:0> val1 => "hey" irb(main):006:0> val2 => "now" Now the fact that the method get_two_values returned strings "hey" and "now" is arbitrary. In fact it could return any two values, they don't even have to be strings.

• php Checking if value exists in array of array

  - by Mark

  I have an array within an array. $a = array ( 0 => array ( 'value' => 'America', ), 1 => array ( 'value' => 'England', ), ) How do I check if 'America' exists in the array? The America array could be any key, and there could be any number of subarrays, so a generalized solution please. Looking on the php manual I see in_array, but that only works for the top layer. so something like in_array("America", $a) would not work. Thanks.

• Populate javascript array with PHP array of Variables

  - by user1704514

  The following code is used to populate a pie chart in javascript: <script type="text/javascript"> var agg = { label: 'Aggressive', pct: [60, 10, 6, 30, 14, 10] }, bal = { label: 'Balanced', pct: [24, 7, 2, 18, 13, 36] }, mod = { label: 'Moderate', pct: [12, 4, 2, 10, 11, 61] }, inc = { label: 'Income', pct: [ 0, 0, 0, 0, 0,100] }, </script> Instead of tm: [40, 60, 67, 30, 74, 50] as seen above, I would like to make each of 6 values a php variable. Like: tm: [$r1, $r2, $r3, $r4, $r5, $r6] . How do I do this? How do I do this with? A php array or json encode?

• How to move positions within an array?

  - by Jade Mulholland

  A program that simply moves array elements. Two variables: userInputVariable and blankSpaceVariable. I have a 2D array named table. Defined as table[userInputVariable + 1][6] I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program. I then ask the user where they would like to enter a blank space within the array. This blank space acts like a divider for all the other information in the array. For example, if the user enters 10 at the start for the userInputVariable, and then enters 5 for the blank space. Once printed, the numbers should go like this: 1, 2, 3, 4, --, 5, 6, 7, 8, 9, 10. My plan has been to create a for loop and try to move all the numbers in the array back a position starting from the blank space variable. What I currently have, but does not work: for (int i = blankSpaceVariable; i < table.length - 1; i++) { table[i] = table[i + 1]; } table[blankSpaceVariable] = "--"; With my current code, the numbers go like this: 1, 2, 3, 4, 6, 7, 8, 9, 10 Tried completing this a few different ways also, but the other info within my 2D array didn't move with the numbers. So I thought that this approach can hopefully move all the info within my 2D array down, and make way for a blank section. All help is greatly appreciated!

• C++ [] array operator with multiple arguments?

  - by genesys

  Can I define in C++ an array operator that takes multiple arguments? I tried it like this: const T& operator[](const int i, const int j, const int k) const{ return m_cells[k*m_resSqr+j*m_res+i]; } T& operator[](const int i, const int j, const int k){ return m_cells[k*m_resSqr+j*m_res+i]; } But I'm getting this error: error C2804 binary operator '[' has too many parameters

• c++ Array passing dilemma

  - by Thomas

  Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

• Address of array vs. address of array[0] - C language

  - by user324994

  My question is why does the address of an array differ from the address of its first position? I'm trying to write my own malloc, but to start out I'm just allocating a chunk of memory and playing around with the addresses. My code looks roughly like this: #define BUFF_SIZE 1024 static char *mallocbuff; int main(){ mallocbuff = malloc(BUFF_SIZE); printf("The address of mallocbuff is %d\n", &mallocbuff); printf("The address of mallocbuff[0] is %d\n", &mallocbuff[0]); } &mallocbuff is the same address every time I run it. &mallocbuff[0] is some random address every time. I was expecting the addresses to match each other. Can anyone explain why this isn't the case?

• Perl array and hash manipulation using map

  - by somebody

  I have the following test code use Data::Dumper; my $hash = { foo => 'bar', os => 'linux' }; my @keys = qw (foo os); my $extra = 'test'; my @final_array = (map {$hash->{$_}} @keys,$extra); print Dumper \@final_array; The output is $VAR1 = [ 'bar', 'linux', undef ]; Shouldn't the elements be "bar, linux, test"? Why is the last element undefined and how do I insert an element into @final_array? I know I can use the push function but is there a way to insert it on the same line as using the map command? Basically the manipulated array is meant to be used in an SQL command in the actual script and I want to avoid using extra variables before that and instead do something like: $sql->execute(map {$hash->{$_}} @keys,$extra);

• Extracting the most duplicate value from an array in JavaScript (with jQuery)

  - by TK

  I have several array to deal with. I need to extract the most duplicate value from each array. From [3, 7, 7, 7], I need to find the value 7. Each array size is 4. For now, I don't have to think about when the most duplicate values are more than one such as [3, 7, 7, 7]. All the values are a number. I looked around the web. I found several ways to make an array to become uniq(). But I haven't found a way to get the duplicate value. I am using jQuery, but raw JavaScript is fine for this task.

• How to define an array inside a function in C?

  - by Arunav Dev

  So in my source file I have the folowin function: void update(state* old_state, state* measurement, uint32_t size) { state new_state[size]; //some function using measurement and old_state and returning the result in newstate arm_fadd_32(measurement,old_state,newstate,size); // rest of the code } Now the compiler throws an error saying that error#28:expression must have a constant value. I think it's due to the fact that even though inside the method the size local variable is not changing the compiler is expecting a constant while defining the size. I have tried the following: int const a = size; and then tried to reinitialize it says constant value is not known. I did some research in internet and it appears that there is no easier way without using malloc, which I don't want to since I am using the code for some embedded application. Is there a way to avoid this problem without really using malloc? Thanks in advance guys!

• php: parsing and converting array structure

  - by mwb

  I need to convert one array structure into another array structure. I hope someone will find it worthy their time to show how this could be done in a simple manner. It's a little above my array manipulation skills. The structure we start out with looks like this: $cssoptions = array( array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'width' , 'value' => '200px' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'margin-right' , 'value' => '20px' ) // end data set , array( 'group' => 'Colors' , 'selector' => '#content' , 'rule' => 'color' , 'value' => '#444' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '.sidebar' , 'rule' => 'margin-top' , 'value' => '10px' ) // end data set ); // END $cssoptions It's a collection of discreet datasets, each consisting of an array that holds two key = value pairs describing a 'css-rule' and a 'css-rule-value'. Further, each dataset holds a key = value pair describing the 'css-selector-group' that the 'css-rule' should blong to, and a key = value pair describing a 'rule-group' that should be used for structuring the rendering of the final css into a neat css code block arranged by the kind of properties they describe (colors, measurement, typography etc..) Now, I need to parse that, and turn it into a new structure, where the: 'rule' => 'rule-name' , 'value' => 'value-string' for each dataset is converted into: 'rule-name' => 'value-string' ..and then placed into a new array structure where all 'rule-name' = 'value-string' pairs should be aggregated under the respective 'selector-values' Like this: '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block ..and finally all those blocks should be grouped under their respective 'style-groups', creating a final resulting array structure like this: $css => array( 'Measurements' => array( '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block , '.sidebar' => array( 'margin-top' => '10px' ) // end selector block ) // end rule group , 'Colors' => array( '#content' => array( 'color' => '#444' ) // end selector block ) // end rule group ); // end css

• splice() not working on correctly

  - by adardesign

  I am setting a cookie for each navigation container that is clicked on. It sets an array that is joined and set the cookie value. if its clicked again then its removed from the array. It somehow buggy. It only splices after clicking on other elements. and then it behaves weird. It might be that splice is not the correct method Thanks much. var navLinkToOpen; var setNavCookie = function(value){ var isSet = false; var checkCookies = checkNavCookie() setCookieHelper = checkCookies? checkCookies.split(","): []; for(i in setCookieHelper){ if(value == setCookieHelper[i]){ setCookieHelper.splice(value,1); isSet = true; } } if(!isSet){setCookieHelper.push(value)} setCookieHelper.join(",") document.cookie = "navLinkToOpen"+"="+setCookieHelper; } var checkNavCookie = function(){ var allCookies = document.cookie.split( ';' ); for (i = 0; i < allCookies.length; i++ ){ temp = allCookies[i].split("=") if(temp[0].match("navLinkToOpen")){ var getValue = temp[1] } } return getValue || false } $(document).ready(function() { $("#LeftNav li").has("b").addClass("navHeader").not(":first").siblings("li").hide() $(".navHeader").click(function(){ $(this).toggleClass("collapsed").nextUntil("li:has('b')").slideToggle(300); setNavCookie($('.navHeader').index($(this))) return false }) var testCookies = checkNavCookie(); if(testCookies){ finalArrayValue = testCookies.split(",") for(i in finalArrayValue){ $(".navHeader").eq(finalArrayValue[i]).toggleClass("collapsed").nextUntil(".navHeader").slideToggle (0); } } });
