未经测试（但从工作脚本修改）：


函数随机（低，高）

{

（数学）

{

返回楼层（随机（）*（1 +高 - 低） ）+低）;

}

}


var unSorted = new Array（5）;

var Sorted = new Array（5）;

var used = new Array（5）;


unSorted [1] =''< a href =" one.html">一个< / a>'';

unSorted [2] =''< a href =" two.html">两个< / a> ;';;

unSorted [3] =''< a href =" three.html"> Three< / a>'';

unSorted [ 4] =''< a href =" four.html">四< / a>'';

unSorted [5] =''< a href ="五。 html"> Five< / a>'';


for（ii = 1; ii< = 5; ii ++）

{

使用[ii] = false;

}


for（ii = 1; ii < = 5; ii ++）

{

randomNumber = Random（1,5）;

while（used [randomNumber]）

{

randomNumber = Random（1,5）;

}

sorted [ii] = inSorted [randomNumber] ;

使用[randomNumber] = true;

}

Untested (but modified from a working script):

function Random( low, high )
{
with( Math )
{
return floor(random() * ( 1 + high - low ) + low );
}
}

var unSorted = new Array( 5 );
var Sorted = new Array( 5 );
var used = new Array( 5 );

unSorted[ 1 ] = ''<a href="one.html">One</a>'';
unSorted[ 2 ] = ''<a href="two.html">Two</a>'';
unSorted[ 3 ] = ''<a href="three.html">Three</a>'';
unSorted[ 4 ] = ''<a href="four.html">Four</a>'';
unSorted[ 5 ] = ''<a href="five.html">Five</a>'';

for( ii=1; ii<=5; ii++ )
{
Used[ ii ] = false;
}

for( ii=1; ii<=5; ii++ )
{
randomNumber = Random( 1, 5 );
while( used[ randomNumber ] )
{
randomNumber = Random( 1, 5 );
}
sorted[ ii ] = inSorted[ randomNumber ];
used[ randomNumber ] = true;
}

function Random( low, high )
{
with( Math )
{
return floor(random() * ( 1 + high - low ) + low );
}
}

var unSorted = new Array( 5 );
var Sorted = new Array( 5 );
var used = new Array( 5 );

unSorted[ 1 ] = ''<a href="one.html">One</a>'';
unSorted[ 2 ] = ''<a href="two.html">Two</a>'';
unSorted[ 3 ] = ''<a href="three.html">Three</a>'';
unSorted[ 4 ] = ''<a href="four.html">Four</a>'';
unSorted[ 5 ] = ''<a href="five.html">Five</a>'';

for( ii=1; ii<=5; ii++ )
{
Used[ ii ] = false;
}

for( ii=1; ii<=5; ii++ )
{
randomNumber = Random( 1, 5 );
while( used[ randomNumber ] )
{
randomNumber = Random( 1, 5 );
}
sorted[ ii ] = inSorted[ randomNumber ];

以上行应为：


排序[ii] = unSorted [randomNumber];

使用[randomNumber] = true;
}

Above line should read:

sorted[ ii ] = unSorted[ randomNumber ];
used[ randomNumber ] = true;
}

{

}

var unSorted = new Array( 5 );

var used = new Array( 5 );

unSorted[ 1 ] = ''<a href="one.html">One</a>'';
unSorted[ 2 ] = ''<a href="two.html">Two</a>'';

for( ii=1; ii<=5; ii++ )
{
Used[ ii ] = false;

对不起，没有错字。应该是：


使用[ii] = false;

}

for（ii = 1; ii< = 5; ii ++）
{
randomNumber = Random（1,5）;
while（used [randomNumber]）
{
randomNumber = Random（1,5）;
}
排序[ii] = inSorted [randomNumber];
使用[randomNumber] = true;
}

Sorry, another typo. Should be:

used[ ii ] = false;
}

for( ii=1; ii<=5; ii++ )
{
randomNumber = Random( 1, 5 );
while( used[ randomNumber ] )
{
randomNumber = Random( 1, 5 );
}
sorted[ ii ] = inSorted[ randomNumber ];
used[ randomNumber ] = true;
}
