JS vs jQuery jQuery Selectors jQuery HTML jQuery CSS jQuery DOM The 'rows' you traverse with an outer loop with a step of 3 and the 'columns' you traverse with an inner loop with a step of 1. JS JSON JSON Intro JSON Syntax JSON vs XML JSON Data Types JSON Parse JSON Stringify JSON Objects JSON Arrays JSON Server JSON PHP JSON HTML JSON JSONP Btw a multi-dimensional array is actually (deep down) a one dimensional array, which is handled a little bit different especially when it comes to accessing its elements.

If youd need to sort them before that, youd get O (nlog n+mlog m). JS Objects Object Definitions Object Properties Object Methods Object Display Object Accessors Object Constructors Object Prototypes Object Iterables Object Sets Object Maps Object Reference You could assume that both arrays are in the same order, and run only one loop: O (min (n,m)). jQuery 3.0 it is deprecated and no longer exists. If you just want the name of the first matching property to be returned, you could instead return just the first matching key that’s found.JS Tutorial JS HOME JS Introduction JS Where To JS Output JS Statements JS Syntax JS Comments JS Variables JS Let JS Const JS Operators JS Arithmetic JS Assignment JS Data Types JS Functions JS Objects JS Events JS Strings JS String Methods JS String Search JS String Templates JS Numbers JS BigInt JS Number Methods JS Number Properties JS Arrays JS Array Methods JS Array Search JS Array Sort JS Array Iteration JS Array Const JS Dates JS Date Formats JS Date Get Methods JS Date Set Methods JS Math JS Random JS Booleans JS Comparisons JS If Else JS Switch JS Loop For JS Loop For In JS Loop For Of JS Loop While JS Break JS Iterables JS Sets JS Maps JS Typeof JS Type Conversion JS Bitwise JS RegExp JS Precedence JS Errors JS Scope JS Hoisting JS Strict Mode JS this Keyword JS Arrow Function JS Classes JS Modules JS JSON JS Debugging JS Style Guide JS Best Practices JS Mistakes JS Performance JS Reserved Words if you have multiple versions of php like php 5.6 and php 7.0. Results = getMatchingKeys(arr, required) See the other answers for examples of that. If you have more nested arrays, a recursive version would be better. As others have noted, this will only for for a 2-dimensional array. Partial matches will be more difficult to achieve.Īrr = inarray only operates on a one dimensional array, so you need to loop over each sub array and run inarray on each. This is particularly useful if you have to search for a value multiple times and the values are simple things like strings AND you are looking for an exact match. One idea would be to create a look up for the objects.
