How do I shift an array of items up by 4 places in Javascript
array1 = array1.concat(array1.splice(0,3));run the following in Firebug to verify
var array1 = ["t0","t1","t2","t3","t4","t5"];console.log(array1);array1 = array1.concat(array1.splice(0,3));console.log(array1);results in
["t0", "t1", "t2", "t3", "t4", "t5"]["t3", "t4", "t5", "t0", "t1", "t2"]
function shiftArray(theArray, times) { // roll over when longer than length times = times % theArray.length; var newArray = theArray.slice(times); newArray = newArray.concat(theArray.slice(0, times)); return newArray;}var array1 = ["t0","t1","t2","t3","t4","t5"];var array2 = shiftArray(array1, 3);alert(array2); // ["t3","t4","t5","t0","t1","t2"]
