Como especificar o target numa função javascript?

Olá,

Gostaria de abrir os links num target"_blank", mas não estou conseguindo, gostaria de saber como proceder, segue abaixo o código que estou usando:

//-3) time between switching the ad, in milliseconds -\\

var refreshTime = 5000; //- 5000 ms = 5 seconds -\\

//-4) number of ads to rotate -\\

var numAds = 3;

 

function makeAd() {

	this.width = ''

	this.height = ''

	this.src = ''

	this.href = ''

	this.mouseover = ''

	this.sponsor = ''

}

 

var ads = new Array()

for(var i = 1; i <= numAds; i++) { ads* = new makeAd() }*

 

//- 5) Copy and paste the lines between the banner definition for

//each banner you want to rotate and be sure to change numAds to

//the number of banners (look about 15 lines up for numAds)

i = 1;

 

 

/------------begin banner definition----------/

*ads**.width = "130" //width of image*

*ads**.height = "162" //height of image*

*ads**.src = "banners/banner1.jpg" //image url*

*ads**.href = "lancamentos/unique/home.html" //link url*

*ads**.mouseover = "Unique" //text to display when mouse moves over banner*

*ads**.sponsor = "Unique" //text to display for text link under banner*

i++

/-------------end banner definition-----------/

 

 

*ads**.width = "130" *

*ads**.height = "162" *

*ads**.src = "banners/banner2.jpg" *

*ads**.href = "lancamentos/monumental/home.htm" *

*ads**.mouseover = "Monumental Business" *

*ads**.sponsor = "Monumental Business" *

i++

 

*ads**.width = "130" *

*ads**.height = "162" *

*ads**.src = "banners/banner3.jpg" *

*ads**.href = "lancamentos/franca/home.htm" *

*ads**.mouseover = "Residencial França" *

*ads**.sponsor = "Residencial França" *

i++

 

 

var myCode = '';

do {

var n= Math.floor(Math.random() (numAds + 1) + 1);*

} while(n > numAds);

var current_ad = n;

myCode = getCode(n);

 

*function getCode(adNumber){*

*	var tempCode = ""*

tempCode += ('<a href="'+ ads[adNumber].href +'" \n')

tempCode += ('onMouseOver="status=\''+ ads[adNumber].mouseover +'\';return true" \n')

tempCode += ('onMouseOut="status=\'\'"> \n')

tempCode += ('<img src="' + ads[adNumber].src + '" width=' + ads[adNumber].width)

tempCode += (' onLoad="setTimeout(\'newAd();\',' + refreshTime + ');"')

tempCode += ('\n height=' + ads[adNumber].height + ' border=0 >')

*	//tempCode += ('<br>Sponsored by: <b>' + ads[adNumber].sponsor + '</b>') //delete this line if you don't want any text to be displayed under your banner*

*	tempCode += ('</a>')*

*	return tempCode;*

}

 

function newAd(){

current_ad++;

if (current_ad > numAds)

current_ad = 1;

if (document.all){

write(getCode(current_ad));

}

}

 

function write(text){

if (document.layers) {

document.bannerAd.document.write(text)

document.bannerAd.document.close();

}

else

if (document.all)

document.all.bannerAd.innerHTML = text

 

}

 

 

Eu tentei definir o target na tag abaixo, mas dá erro na exibição da página:

 

*ads**.href = "lancamentos/monumental/home.htm" target="_blank" *

 

 

Também tentei sem sucesso inserir o target na tag:

 

tempCode += ('<a href="'+ ads[adNumber].href +'" \n')

 

Imagino ser algo simples, mas como não sou um conhecedor de javascript, estou "apanhando" um pouco.
