Copy Code code as follows: Used for trimming whitespace Trimleft =/^\s+/, TrimRight =/\s+$/, Use native String.Trim function wherever possible Trim:trim? function (text) { return text = null?

, add it to the Array.prototype, and use it. function Array_max () {var i, max = this[0]; for (i = 1; i After the code executes, Y saves the maximum value in the array x, or says 6. All JScript internal objects have read-only prototype properties. You can add functionality to the prototype as in this example, but the object cannot be given a different prototype. However, user-defined objects can be assigned to a new prototype. The list of methods and attributes for each internal object in the la
