In search engine robot searches, the type,text/html for such "text" is the highest (except at this stage Text/xml), and text/javascript this kind of friendly degree is not ideal, If robot also wants to judge the DHTML code, the complexity is higher and is not zoned, so if you want to increase the friendliness of your code when you are programming with DHTML. A better approach would be to "simplify DHTML code to code that has no HTML as much as possibl

); The "function" nbsp; nbsp; examples show that the operands of the typeof operator can be either a variable (message) or a literal number. Note that TypeOf is an operator rather than a function, so the parentheses in the example are not required (although they can be used). nbsp; nbsp; From the above example, we found that numbers created with number () are also returned with the value "Object" by TypeOf,

This example is JavaScript to create a linked list ...
And sort this out ...
It can also be extended on the GenericList general list.
To achieve a variety of sorting and increase, delete, change node.
The code is as follows:
function Node () {
This.data=null;
This.next=null;
}
function GenericList () {
This.head=null;
This.current=null;
All the linked list nodes are played.

Use JavaScript to take the float type decimal point two, example 22.127456 to take 22.13, how to do?1. The dumbest way ... [I'll do what I do ...]1function get ()2{3 var s = 22.127456 + "";4 var str = s.substring (0,s.indexof (".") + 3);5 alert (str);6}2. Regular expression effect is good13. He is more clever ...14.

So how do we solve this problem, and then we'll talk about the second way, and it's the way jquery uses it.
The second way
var A = function () {return
new A.prototype.init ();//①
}
a.prototype = {
init:function () {
this.age = N;
Console.log (this);
return this;
},
age:100
}
A.prototype.init.prototype = A.prototype;//②
var a = new A ();

1. Method description, the array of reduce () to a function in this array of [X1, x2, x3 ...] , this function must receive two parameters, reduce () to continue the result and the next element of the sequence to do the cumulative calculation, the effect is:
[X1, x2, X3, x4].reduce (f) = f (f (f (x1, x2), x3), x4)
2. Using the example
' Use strict ';
