"scrollende" tekst
Hej,
Jeg skal bruge en eller anden form for "boks" eller anden form for element, med en scrollende tekst i - findes der sådanne færdige moduler til download (java-applet, javascript, flash, whatever) eller skal man selv lave sådan noget?
// If you want it to move faster you can set this lower, it's the timeout: var speed = 30;
// Sets variables to keep track of what's happening var loop, timer;
// Element Object function makeObj(obj,nest){ nest=(!nest) ? "":'document.'+nest+'.'; this.el=bw.dom?document.getElementById(obj):bw.ie4?document.all[obj]:bw.ns4?eval(nest+'document.'+obj):0; this.css=bw.dom?document.getElementById(obj).style:bw.ie4?document.all[obj].style:bw.ns4?eval(nest+'document.'+obj):0; this.scrollHeight=bw.ns4?this.css.document.height:this.el.offsetHeight; this.clipHeight=bw.ns4?this.css.clip.height:this.el.offsetHeight; this.up=goUp;this.down=goDown; this.moveIt=moveIt; this.x=0; this.y=0; this.obj = obj + "Object"; eval(this.obj + "=this"); return this }
// A unit of measure that will be added when setting the position of a layer. var px = bw.ns4||window.opera?"":"px";
function moveIt(x,y){ this.x = x this.y = y this.css.left = this.x+px this.css.top = this.y+px }
//Makes the object go up function goDown(move){ if (this.y>-this.scrollHeight+oCont.clipHeight){ this.moveIt(0,this.y-move) if (loop) setTimeout(this.obj+".down("+move+")",speed) } } //Makes the object go down function goUp(move){ if (this.y<0){ this.moveIt(0,this.y-move) if (loop) setTimeout(this.obj+".up("+move+")",speed) } }
//Calls the scrolling functions. Also checks whether the page is loaded or not. function scroll(speed){ if (scrolltextLoaded){ loop = true; if (speed>0) oScroll.down(speed) else oScroll.up(speed) } }
//Stops the scrolling (called on mouseout) function noScroll(){ loop = false if (timer) clearTimeout(timer) }
//Makes the object var scrolltextLoaded = false function scrolltextInit(lmnt, srll){ if(document.getElementById(lmnt)){ oCont = new makeObj(lmnt); oScroll = new makeObj(srll,lmnt); oScroll.moveIt(0,0); oCont.css.visibility = "visible"; scrolltextLoaded = true; } }
function initScrollable(lmnt, srll){ if (bw.bw) scrolltextInit(lmnt, srll); }
Skulle du bruge flere forskellige størrelser, kan du definere flere slags i css'en, og f. eks kalde dem divScrollTextCont2 og divText2, og tilføje det sådan i body...
