The example in this article describes how to remove duplicate values from an array using JavaScript. Share it with everyone for your reference. The details are as follows:
var unique = function(origArr) { var newArr = [], origLen = origArr.length, found, x, y; for ( x = 0; x < origLen; x++ ) { found = undefined; for ( y = 0; y < newArr.length; y++ ) { if ( origArr[x] === newArr[y] ) { found = true; break; } } if ( !found) newArr.push( origArr[x] ); } return newArr; } var myarray = ['jeffrey', 'allie', 'patty', 'damon', 'zach', 'jeffrey', 'allie', 'patty', 'damon', 'zach', 'joe']; myarray = unique(myarray); alert(myarray.join(', '));
I hope this article will be helpful to everyone’s JavaScript programming design.
