许愿墙中用到的函数_javascript技巧

复制代码 代码如下:

<script> <BR>//-- 控制层删除start of script --> <BR>function ssdel(){ <BR>if (event) <BR>{ <BR>lObj = event.srcElement ; <br><br>while (lObj && lObj.tagName != "DIV") lObj = lObj.parentElement ; <BR>} <BR>var id=lObj.id <BR> document.getElementById(id).removeNode(true); <BR> //document.getElementById(id).outerHTML="";// <BR> } <br><br>//-- 控制层删除End of script --> <BR></script>
<script> <BR>//-- 控制层移动start of script --> <BR>var Obj='' <BR>var index=10000;//z-index; <BR>document.onmouseup=MUp <BR>document.onmousemove=MMove <br><br>function MDown(Object){ <BR>Obj=Object.id <BR>document.all(Obj).setCapture() <BR>pX=event.x-document.all(Obj).style.pixelLeft; <BR>pY=event.y-document.all(Obj).style.pixelTop; <BR>} <br><br>function MMove(){ <BR>if(Obj!=''){ <BR> document.all(Obj).style.left=event.x-pX; <BR> document.all(Obj).style.top=event.y-pY; <BR> } <BR>} <br><br>function MUp(){ <BR>if(Obj!=''){ <BR> document.all(Obj).releaseCapture(); <BR> Obj=''; <BR> } <BR>} <br><br>function setTagBPic(i) { <BR> picurl = getBPic(i); <BR> getObj('tagBPic').style.background = " transparent url(\"" + picurl + "\") no-repeat scroll bottom left"; <BR> cf.tagbgpic.value = i; <BR>} <br><br>function setTagBColor(i) { <BR> color = getBColor(i); <BR> getObj('preview').style.background = '' + color; <BR> cf.tagbgcolor.value = i; <BR>} <br><br><BR>function getBPic(i) { <BR> i = (i<1 || i>8)?1:i; <BR> return "images/pic" + parseInt(parseInt(i)+27) +".gif"; <BR>} <BR>//-- 控制层移动end of script --> <BR>//获得焦点; <BR>function getFocus(obj) <BR>{ <BR> if(obj.style.zIndex!=index) <BR> { <BR> index = index + 2; <BR> var idx = index; <BR> obj.style.zIndex=idx; <BR> //obj.nextSibling.style.zIndex=idx-1; <BR> } <BR>}<BR></script>
