On a large portal website, we will see that the ads displayed for the first time are different. Next I will introduce you to the random array strings. In fact, the ads are almost random.
Instance
| The Code is as follows: |
Copy code |
<Script language = "JavaScript" type = "text/JavaScript">
TheAds = new Array ();
Shu = 13;
Dot = '';
TheAds [1] = 'www. bKjia. c0m 1st ';
TheAds [2] = 'www. bKjia. c0m 2's ';
TheAds [3] = 'www. bKjia. c0m Article 3 ';
TheAds [4] = 'www. bKjia. c0m 4 ';
TheAds [5] = 'www. bKjia. c0m Article 5 ';
TheAds [6] = 'www. bKjia. c0m Article 6 ';
TheAds [7] = 'www. bKjia. c0m article 7 ';
TheAds [8] = 'www. bKjia. c0m article 8 ';
TheAds [9] = 'www. bKjia. c0m 9 ';
TheAds [10] = 'www. bKjia. c0m Article 10 ';
TheAds [11] = 'www. bKjia. c0m 11th ';
TheAds [12] = 'www. bKjia. c0m 12th ';
TheAds [13] = 'www. bKjia. c0m 13th ';
Adshu = shu + 1
Function Quickpick ()
{
Var ball
For (ball = 1; ball <adshu; ball ++)
{
This [ball] = parseInt (Math. random () * shu + 1 );
For (var list = 0; list <ball; list ++)
{
If (this [list] = this [ball])
{
List = ball;
Ball --;
}
}
}
Return this;
}
Var idx;
Var ballball = new Array (shu );
Ballball = this. Quickpick ();
For (idx = 1; idx <adshu; idx ++ ){
Document. write (dot + theAds [ballball [idx] + '<br> ');
If (idx <shu) {document. write ('')}}
// Document. write (dot + theAds2 );
</Script> |
A random array sorting Function
| The Code is as follows: |
Copy code |
Var wangwangList = ['Consult online', 'Consult online1', 'Consult online2', 'Consult online3']; /**
* Random Prepayment
* @ Param trademanager Name List
* @ Returns HTML code
**/
Function randomWangWang (){
Var B, C;
Var X = [];
Var j = 0;
For (I = A. length; I> = 1; I --){
C = Math. floor (Math. random () * A. length );
X [j] = outWangWangCode (A [C]);
A. splice (C, 1)
J ++;
}
Return X
} /**
* Convert to HTML link form
* @ Param trademanager name
* @ Returns HTML code
**/
Function outWangWangCode (n ){
Var _ n = encodeURIComponent (n );
Var html = '';
Html + ='
<LI> <A class = img title = click here to send me A message href = "http://amos.im.alisoft.com/msg.aw? V = 2 & uid = '+ _ n +' & site = cntaobao & s = 1 & charset = UTF-8 "target = _ blank> ';
Html + = ' </A> '+ n +' </LI> ';
Return html;
} /**
* Transfer out all lists
* @ Param write mode or return Mode
* @ Returns HTML code
**/
Function writeWangWangHTML (write ){
Var html ='
<UL> ';
Var x = randomWangWang (wangwangList );
For (I in x ){
Html + = x [I];
}
Html + = '</UL> ';
Return html;
} // Display code
Document. write (writeWangWangHTML ()); |
