An array is a special variable, which can hold more than one value at a time. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this: $cars1 = "Volvo"; $cars2 = "BMW"; $cars3 = "Toyota"; For a pure JavaScript solution you could just traverse the array. function contains( r, val ) { var i = 0, len = r.length; for(; i < len; i++ ) { if( r[i] === val ) { return i; } } return -1; } var_dump ($array); The above example will output: array(4) { [0]=> string(3) "foo" [1]=> string(3) "bar" [2]=> string(5) "hello" [3]=> string(5) "world" } Remove Items From JavaScript Arrays. JavaScript arrays allow you to group values and iterate over them.

Arrays in Bash are one-dimensional array variables.

Var array

Note that since source is an array, variable refers to the base variable of the array in order to also know what the array is. Had it asked for a variable, %Gentodo would have been treated as just that single Using Array literal notation if you put a number in the square brackets it will return the number while using new Array () if you pass a number to the constructor, you will get an array of that length. you call the Array () constructor with two or more arguments, the arguments will create the array elements. I am trying to build an array variable like this: [ [ "1-Initial Response","10" ] [ "2-Initial Response","20" ] ] So at some point during the flow I would like to read the second value based on a condition. i.e.

How to create a data-element based on a JSON object array?

An array object contains a number of variables. The number of variables may be zero, in which case the array is said to be empty. The variables contained in an array have no names; instead they are referenced by array access expressions that use non-negative integer index values. Array = function() { }; var x = new Array(); // x is now an Object instead of an Array. In other words, [] is unambiguous.
