Copy script ini ke address bar kamu

javascript:gukztab=location.href;tab=prompt('How tabs(s) did you open?', '');if(tab){var%20link=new%20Array();var%20tinggi=new%20Array();var%20lebar=new%20Array();var%20tabs='';for(i=0;i<tab;i+=1){link[i]=prompt('Input Link for tab '+(i+1)+' of '+tab+' (ex: http://entry44.blogspot.com)',link[0]||'http://');tinggi[i]=prompt('Input Height for tab '+(i+1)+' of '+tab+' (in %)',tinggi[0]||'100%');lebar[i]=prompt('Input Width for tab '+(i+1)+' of '+tab+' (in %)',lebar[0]||'50%');tabs+='<iframe%20src=\''+link[i]+'\'%20height=\''+tinggi[i]+'\'%20width=\''+lebar[i]+'\'%20frameborder=\'0\'></iframe>';}with(document){write(tabs);void(close());}}else{void(null);}
