Hallo,
ich möchte gerne eine Slideshow in meine HP einfügen. Da ich überhaupt keine Ahnung von JavaScript habe, bin ich auf vorgefertigte Scripte angewiesen. Ich hab mich für ein Script entschieden, das meine Wünsche erfüllt. Nur komm ich bei diesem mit meinen CSS-Kenntnissen nicht weiter was die Anzeigegröße der Bilder betrifft. Diese würde ich gerne als relative Größe (also mit %) angeben, nur ich weiß nicht, wie. Bitte helft mir.
Die Stelle im Script, wo die Größe festgeschrieben ist, ist - vermute ich - folgende:
//insert css and images
this.b_insert= function(){
var b, thestylid, thez, thevis, slidehei;
slidehei=(showcontr)?(pichei+25):(pichei); //add space for the controls
var myhtml="<div style='width:"+picwid+"px;height:"+slidehei+"px;'>";
myhtml+="<div style='position:absolute;width:"+picwid+"px;height:"+pichei+"px;'>";
for(b=1;b<=emax;b++){
thez=1;thevis='hidden';
if(b<=1) {thez=2; thevis='visible';}
myhtml+="<div id='img_"+slideid+"_"+b+"' style='font-size:0;line-height:"+pichei+"px;margin:0;padding:0;text-align:center;visibility:"+thevis+";z-index:"+thez+";position:absolute;left:0;top:0;width:"+picwid+"px;height:"+pichei+"px;background-color:"+backgr+";'>";
myhtml+="<img src='"+imges[(b-1)]+"' style='vertical-align:middle;border:0;' alt=''/></div>";
}
myhtml+="</div>";
Hier nochmal das ganze Script:
