slide show

xiao_yee

我有一个slide show,如何写得under user control? 开始时，会自动跳动

delay = 3000;

function loadXML(loaded) {
if (loaded) {
  xmlNode = this.firstChild;
  image = [];
  id = [];
  description = [];
  total = xmlNode.childNodes.length;
  for (i=0; i<total; i++) {
   image[ i ] = xmlNode.childNodes[ i ].childNodes[0].firstChild.nodeValue;
   id[ i ] = xmlNode.childNodes[ i ].childNodes[4].firstChild.nodeValue;
   description[ i ] = xmlNode.childNodes[ i ].childNodes[7].firstChild.nodeValue;
  }
  firstImage();
} else {
  c;
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
p = 0;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {
  preloader.preload_bar._xscale = 100*loaded/filesize;
} else {
  preloader._visible = false;
  if (picture._alpha<100) {
   picture._alpha += 10;
  }
}
};
function nextImage() {
if (p<(total-1)) {
  p++;
  if (loaded == filesize) {
   picture._alpha = 0;
   picture.loadMovie(image[p], 1);
   desc_txt.text = description[p];
   picture_num();
   slideshow();
  }
}
}
function prevImage() {
if (p>0) {
  p--;
  picture._alpha = 0;
  picture.loadMovie(image[p], 1);
  desc_txt.text = description[p];
  picture_num();
}
}
  
function firstImage() {

if (loaded == filesize) {
  picture._alpha = 0;
  picture.loadMovie(image[0], 1);
  desc_txt.text = description[0];
  picture_num();
  slideshow();
}
}
function picture_num() {
current_pos = p+1;
pos_txt.text = current_pos+" / "+total;
}
function slideshow() {
myInterval = setInterval(pause_slideshow, delay);
function pause_slideshow() {
  clearInterval(myInterval);
  if (p == (total-1)) {
   p = 0;
   firstImage();
  } else {
   nextImage();
  }
}
}
//当click stop,按钮会变成'play',movie就停
//control movie
control.onPress =  function(){
resetCtr();
myCtr[0] = true;
control.gotoAndStop(2);//变成‘play'
}
myCtr = 2;
resetCtr();
function resetCtr() {
for (j=0;j<myCtr;j++) {
  myAct[j] = false;
}
control.gotoAndStop(1);//变成‘stop’
}
//按了，就变成上一页
slide_back.onPress =  function(){
if (p>0) {
  p--;
  picture._alpha = 0;
  picture.loadMovie(image[p], 1);
  desc_txt.text = description[p];
  picture_num();
}
}
//按了，就变成下一页 （如何停slide show?按了，它跳去下一页，但还继续slide show）
slide_next.onPress =  function(){
if (p<(total-1)) {
  p++;
  if (loaded == filesize) {
   picture._alpha = 0;
   picture.loadMovie(image[p], 1);
   desc_txt.text = description[p];
   picture_num();
  }
}
}

没有触发不可能会继续走，除非电脑闹鬼。

我很早以前就理解一样事情，电脑没有奇迹，只有人为程序。
你尝试用trace去解决一下再看怎样。

我在研究看看

那至于 我的按钮（movie clip制成），按了，play frame 2,再按, play frame 1.它只会play frame 2,不会回 frame 1. 我这里，有那点是错了？


//control movie
control.onPress =  function(){
resetCtr();
myCtr[0] = true;
control.gotoAndStop(2);//变成‘play'
}
myCtr = 2;
resetCtr();
function resetCtr() {
for (j=0;j<myCtr;j++) {
  myAct[j] = false;
}
control.gotoAndStop(1);//变成‘stop’
}
