I have a simple array with bank holidays:
var bank_holidays = ['06/04/2012','09/04/2012','07/05/2012','04/06/2012','05/06/2012','27/08/2012','25/12/2012','26/12/2012','01/01/2013','29/03/2013','01/04/2013','06/05/2013','27/05/2013']; I want to do a simple check to see if certain dates exist as part of that array, I have tried:
if('06/04/2012' in bank_holidays) { alert('LOL'); } if(bank_holidays['06/04/2012'] !== undefined) { alert 'LOL'; } And a few other solutions with no joy, I have also tried replacing all of the forwarded slashes with a simple 'x' in case that was causing issues.
Any recommendations would be much appreciated, thank you!
(edit) Here's a jsFiddle - http://jsfiddle.net/ENFWe/
581
function checkIfArrayIsUnique(myArray) { for (var i = 0; i < myArray. length; i++) { for (var j = 0; j < myArray. length; j++) { if (i != j) { if (myArray[i] == myArray[j]) { return true; // means there are duplicate values } } } } return false; // means there are no duplicate values. }
To check if all values in an array are equal:Use the Array. every() method to iterate over the array. Check if each array element is equal to the first one. The every method only returns true if the condition is met for all array elements.
If you don't care about legacy browsers:
if ( bank_holidays.indexOf( '06/04/2012' ) > -1 ) if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:
if ( $.inArray( '06/04/2012', bank_holidays ) > -1 ) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
