Javascript static pages to implement random display of ads

First, we need to generate random numbers that do not repeat within n and put the generated random numbers into another Array, and use the following method to complete it:

Copy the codeThe code is as follows:

 
function getRandomNumbers(count) 
{ 
var numbers = new Array(); 
var original = new Array(); 
for (var i=0;i<count;i++) 
{ 
original[i] = i+1; 
} 
(function(){ return 0.5 - (); }); 
for (var i=0;i<count;i++) 
{ 
numbers[i] = original[i] - 1; 
} 
return numbers; 
} 

Then, in the background program, output the html script:

Copy the codeThe code is as follows:

 
var sf = new Array(); 
sf[0]='<tr><TD width=120><a href=# target=_blank>Server name</a></TD><TD width=110><a href=http://sc. target=_blank>Server IP</a></TD><TD width=160>Opening time</TD><TD align=center width=95>Line category</TD><TD> Version introduction</TD><TD width=105>Customer service QQ</TD><TD align=center width=55><a href=# target=_blank><font color=#000000>Detailed introduction</font></a></TD></tr>';
sf[1]='<tr><TD width=120><a href=# target=_blank>Server name</a></TD><TD width=110><a href=http://s. target=_blank>Server IP</a></TD><TD width=160> Zone opening time</TD><TD align=center width=95>Line category</TD><TD> Version introduction</TD><TD width=105>Customer service QQ</TD><TD align=center width=55><a href=# target=_blank><font color=#000000>Detailed introduction</font></a></TD></tr>';

Then use the previous method to generate a random number and display the html script according to the random number.

Copy the codeThe code is as follows:

 
var numbers = getRandomNumbers(); 
for( i=0;i<;i++ ) 
{ 
(sf[numbers[i]]); 
}
