Random ordering of array elements

function Randomorder (Targetarray) {

var arraylength = targetarray.length; The length of the target array

var tempArray1 = new Array (); Create an array of normal order first

for (var i = 0; i < arraylength; i + +) {//The elements of the target array are assigned to the array tempArray1

TempArray1 [i] = i;

}

Then create an array of random order from the previous array

var tempArray2 = new Array ();

for (var i = 0; i < arraylength; i + +) {

TempArray2 [i] = Temparray1.splice (Math.floor (Math.random () * temparray1.length), 1); Randomly extracting elements from normal sequential arrays

}

Finally create a temporary array to store data from Targetarray based on the last scrambled array

var tempArray3 = new Array ();

for (var i = 0; i < arraylength; i + +) {

TempArray3 [i] = Targetarray [TempArray2 [i]];

}

return tempArray3; Returns the last derived array

}
