[ad_1] //perhaps, you probably do it like this : var result = {}; $.each([{id: 1, add_1: “123”, add_2: “add1”}, {id: 2, add_1: “456”, add_2: “add2”} ], function(i, item ){ for(var pro in item ){ result[pro] = result[pro] || []; result[pro].push(item[pro]); } }) console.log(result); 2 [ad_2] solved How i change array in js get by key … Read more
[ad_1] You can use .map(), .concat() and Object.assign() methods to get the resultant array: let data = [ {Name: ‘Color’, Data:[{Id: 1, Name: ‘Red’}, {Id: 2, Name: ‘Yellow’}, {Id: 3, Name: ‘Blue’}, {Id: 4, Name: ‘Green’}, {Id: 7, Name: ‘Black’}]}, {Name: ‘Size’, Data:[{Id: 8, Name: ‘S’}, {Id: 11, Name: ‘M’}, {Id: 12, Name: ‘L’}, {Id: … Read more
[ad_1] As everyone is refferring – weight is the sum of the numbers, not digits. And the function is simple: var w = 0; for (var i=0; i<arr.length; i++) { w = w + arr[i]; } console.log(w); But if you want to add together all the digits, you were almost correct – number to string, … Read more
[ad_1] I will try to explain it to you without code, since I think you should learn from yourself. You have an array table1 that can only have an element in position 0. You need to give a value to that position like this: table1[0] = new Tables(); now it depends on the complexity you … Read more
[ad_1] I am using the simple approach of type casting from character to integer as, N[i] = (int)s[i] -‘0’; Here N is integer array , s is the character array .I simply type cast the character array into integer , it will treat it as a ASCII code of s[i]. so I minus the ‘0’ … Read more
[ad_1] As mentioned in the comments, array should be initialized with a proper capacity. You should first read the size and then create the array. #include <iostream> using namespace std; int main() { int n; // First read the array size and then create the array. cin>>n; //inputting the array size int array[n]; //inputting the … Read more
[ad_1] You can use sortBy function of lodash. var users = [ { ‘user’: ‘fred’, ‘age’: 48 }, { ‘user’: ‘barney’, ‘age’: 36 }, { ‘user’: ‘fred’, ‘age’: 40 }, { ‘user’: ‘barney’, ‘age’: 34 } ]; _.sortBy(users, [function(o) { return o.user; }]); // => objects for [[‘barney’, 36], [‘barney’, 34], [‘fred’, 48], [‘fred’, 40]] … Read more
[ad_1] As far as I understand you are comfortable with replacing words in a single paragraph and that you are doubtful regarding text with multiple paragraphs. Please look into a function called “getline()” function. This function reads entire your text until it encounters a “\n” element (Next line) So you can use this getline function … Read more
[ad_1] First of all, this: var array = [], and the rest of your code, is not c++ syntax at all, it’s pure javascript. You can’t copy code from one language to another expecting that would compile and run properly. In order to insert all elemnts from N to 0 and then N again to … Read more
[ad_1] If you want to have a random number of arrays you have to store them in a resizable container like a vector, containing the arrays with the six elements. Resize this vector with this random number and then iterate through it and add random numbers #include <array> #include <random> namespace { constexpr auto NumberOfArrayElements … Read more
[ad_1] Your current method is … not quite right, for any kind of sort. Insertion sort would take an element and insert it at the correct index, then shift the already inserted items down appropriately. Something like void looper(int *p) { for (int i = 1;i < 25;i++) { int key = p[i]; int j … Read more
[ad_1] split your string on space to get Logging and v0.12.4 remove (substring) v from v0.12.4 split 0.12.4 on dot (use split(“\\.”) since dot is special in regex) you can also parse each “0” “12” “4” to integer (Integer.parseInt can be helpful). 4 [ad_2] solved Parsing String and Int in java
[ad_1] That is why storing base64 encoded serialized data in the database is extremely bad idea. You have to redesign your database, getting rid of base64_encode and serialized data. While using base64 with database makes absolutely no sense by any means, storing serialized data in the database is like mending an electronic device with stone … Read more
[ad_1] Your problem lies in the use of consecutive if statements without chaining them together to make a complete check. Doing it your way, the code actually completely disregards all the if statements, but the last one. So, if iledefrance.indexOf(departement) != -1 gives false, it’will always execute the code inside else, meaning it’ll set region … Read more
[ad_1] That code is not a declaration, but it can be interpreted as an expression. (*I_dont_know())[(int) ((*ptr))] Call the function I_dont_know with no arguments. This function returns a pointer to something. Dereference the returned pointer to get some object. Meanwhile, dereference the value of ptr and cast it to an int value. Then pass that … Read more
