Q; How to remove a value from a javascript array ?

A: use splice method to cut off value from array

/**
 * remove value fom array
 */
Array.prototype.remove = function(mValue) {

    return this.splice(this.indexOf(mValue), 1);
}

// example array 
var aData = [1, 2, 3, 4, 5];

// usage: remove the value "4"
aData.remove(4);

// gives: [1, 2, 3, 5]
console.log(aData);
