To retrieve the value of foo3, you can just use JSON.Parse with a callback function that will only return the value of foo3 if it is present. Here is a working snippet: var text=”{“foo1″:”1123″,”foo2″:”332″,”foo3″:”23-SEP-15″}”; JSON.parse(text, function(k,v){ if (k === ‘foo3’) { document.write(v); } return v; }); Here, in function(k,v), k stands for the key and … Read more
Just filter the values and map the desired ones. array.filter allows you to filter items of an array with a condition, so using i => i.name === ‘test0′ will return a new array where only the values with name ‘test0’ are acquired. Finally, using map you create a new array, whose values are the result … Read more
In this context, 0 is a null pointer constant. It can be converted, with or without a cast, to any pointer type, giving a null pointer of that type. In modern C++, you can write nullptr to make it more clear that you mean a null pointer, not the number zero. There’s also a NULL … Read more
Your key is invalid.. foreach ($myarray[“docs”] as $myarrays) { echo $myarrays[“property_imgurl”]; } Live preview 2 solved Can’t echo items from array
Because you are filling x[i] with each of the values of scores. You have one extra loop. Since the last value of the slice scores is 83, you are filling x one more time, with 83 for each slot. Simpler would be: for i, _ := range x { // fill up x array with … Read more
I just write this function for him. Please don’t justify people from how he write the code. Maybe it’s easy to say “Hey! Do you know javascript?”. It’s better if you leave some answer or stay quite.

This should look a bit more like a code intended for humans to read 🙂 #include<iostream> #include<string> using namespace std; int ncr; int me,n=0,u,y,l; char opt1,opt2,opt3,opt4; struct student { string Name; int DoB; int Age; string Address; string Course[5]; char grade[5]; }; void add(); void remove(); void update(); void search(); int main() { int opt; … Read more
From your code it looks like you actually want the key and the value… <select name=”country”> <?php foreach($countryArray as $code=>$country){ echo “<option value=”.$code.”>”.$country.”</option>”; } </select 1 solved Get first and second element of array [duplicate]

You can use a regex match to see if the string contains all uppercase letters: var uppercaseletters = /^[A-Z]+$/; if(data2.match(uppercaseletters)) { document.write(‘hey’); } else { document.write(‘nope’); } 2 solved Testing for uppercase, why is toUppercase() alphanumeric in javascript? [closed]
Arrays are great for learning the concepts of coding and as such I endorse them much more than any other standard template library (when it comes to learning code). Note: It is wise to use a vector however the reason schools don’t teach this is because they want you to understand the underlying concepts behind … Read more
It’s because you’re splitting by a single character, you would have to do this eagerly: String[] Operators = stringNumbers.split(“[0-9.]*”); Or you can filter the results: String[] Operators = Arrays.stream(stringNumbers.split(“[0-9.]”)) .filter(str -> !str.equals(“”)) .toArray(String[]::new); 5 solved Why there are empty string while trying to split a string in Java? And how to fix it?
Even though you did check if the file was opened you still continue reading when it failed, that’s wrong, this code will not fail that way, but I assume it will not work either because your file apparently doesn’t exist Also, in the printing loop you are trying to print more elements than there are … Read more
Something like this? It will iterate through your array and you can search for a specific value and type. I don’t want to go into too much detail as your question isn’t entirely clear. function get_rows_by_type($array, $type, $val) { $output = array(); foreach ($array as $a) { if ($a[$type] === $val) { $output[] = $a; … Read more
