手機(jī)圖片滑動(dòng)切換，網(wǎng)上有很多這樣的例子，但都借助于其他組件，讓代碼混亂的不行，本例介紹的是無(wú)css3元素純js腳本編寫的wap圖片滾動(dòng)特效

手機(jī)圖片滑動(dòng)切換，網(wǎng)上有很多這樣的例子，但都借助于其他組件，讓代碼混亂的不行；還有就是用到css3里的 transform：translate（x,y）;移動(dòng)元素,不過(guò)發(fā)現(xiàn)在不支持css3的設(shè)備上馬上完蛋了，所以下定決心自己做一個(gè)，誰(shuí)知出現(xiàn)了很多的問(wèn)題，其中最重要的是給圖片加鏈接，網(wǎng)頁(yè)中的上下滾動(dòng)條不能在拖動(dòng)圖片的時(shí)候滾動(dòng)，并且不能兼容pc機(jī)器上的拖動(dòng)；在這里就簡(jiǎn)單介紹一下遇到的問(wèn)題和解決的方法；

問(wèn)題一：給圖片加上鏈接后，在拖動(dòng)的時(shí)候總是跳到其他頁(yè)面

問(wèn)題根源主要是不能判斷是點(diǎn)擊還是拖動(dòng)，手機(jī)事件一般順序是 touchstart-》mousedown-》mousemove-》touchmove-》mouseup-》touchend-》click，根據(jù)不同手機(jī)可能會(huì)有不同。觸屏手機(jī)的事件一般都用 touchstart -》 touchmove -》 touchend -》 click，click事件是最后執(zhí)行的，當(dāng)我們有touchstart，touchmove，touchend處理完后，如果不進(jìn)行return或取消默認(rèn)就會(huì)觸發(fā)click事件，這樣網(wǎng)頁(yè)就跳走了，解決辦法是記錄touchstart的坐標(biāo)點(diǎn)和touchmove的坐標(biāo)點(diǎn)，根據(jù)兩個(gè)坐標(biāo)點(diǎn)算出觸點(diǎn)是否移動(dòng)過(guò)，其中值得關(guān)注的是事件的Event參數(shù)，觸屏一般是 event.touches，event.targetTouches，event.changedTouches。我在測(cè)試當(dāng)中發(fā)現(xiàn)者三個(gè)參數(shù)的值時(shí)一樣的，不過(guò)值得注意的是touchend事件不會(huì)得到觸點(diǎn)坐標(biāo)（也或許是設(shè)備問(wèn)題），在移動(dòng)的時(shí)候touchmove會(huì)不斷出發(fā)，有時(shí)候touchmove會(huì)不觸發(fā)，其中就是瀏覽器自帶一下功能把觸點(diǎn)（或鼠標(biāo)）脫離了選中的元素，比如上時(shí)間按住會(huì)出現(xiàn)菜單，（pc上圖片就會(huì)生成一個(gè)可以拖動(dòng)的縮略圖），這樣就要在touchstart（mousedown）的時(shí)候先 event.preventDefault();取消默認(rèn)。

問(wèn)題二：網(wǎng)頁(yè)中的上下滾動(dòng)條不能在拖動(dòng)圖片的時(shí)候滾動(dòng)

相信這個(gè)問(wèn)題只要制作過(guò)得都會(huì)遇到，其實(shí)主要是在移動(dòng)（touchmove，mousemove）的時(shí)候取消了默認(rèn)事件event.preventDefault(),在這里我們需要做的是，是否移動(dòng)獲得觸點(diǎn)和開(kāi)始的觸點(diǎn)是否一致，如果一致就直接返回，還要算出是移動(dòng)的x軸多一點(diǎn)還是y軸移動(dòng)的多一點(diǎn)，這樣我們就可以做左右滑動(dòng)的時(shí)候取消默認(rèn)，在上學(xué)的時(shí)候不取消；

問(wèn)題三： 并且不能兼容pc機(jī)器上的拖動(dòng)

這是因?yàn)樵诮壎ㄊ录臅r(shí)候不能完全考慮事件名稱是touchstart還是mousedown ，從網(wǎng)上搜了一下，感覺(jué)做的不做，就直接抄過(guò)來(lái)了

this.eventName={
touchstart:'touchstart',
touchmove:'touchmove',
touchend:'touchend',
}
在做判斷
if(!device){
this.eventName.touchstart='mousedown';
this.eventName.touchmove='mousemove';
this.eventName.touchend='mouseup';
}
dom.addEventListener(this.eventName.touchstart,handleEvent,false);

大概是這個(gè)意思，根據(jù)設(shè)備不同綁定不同的事件

其實(shí)還碰到了很多的問(wèn)題，就不一一說(shuō)明了

不多說(shuō)了，直接把代碼貼出來(lái)了，如果有什么不太好的地方，還請(qǐng)多多包含和提出意見(jiàn)

用法：

在頁(yè)面加載完成后

var obj = {
dom:document.getElementById('wapListImage'),//dom元素
isupdate:true,//是否自動(dòng)切換
time:3000,//自動(dòng)切換的時(shí)間毫秒
isfor:true, //是否循環(huán)播放，即到最后一張是否直接轉(zhuǎn)入第一張，或到第一張直接轉(zhuǎn)入最后一張
leftOrright:'left',//像左側(cè)自動(dòng)切換還是像右側(cè)自動(dòng)切換
callBack:function(obj){//切換成功后回調(diào)函數(shù) 其實(shí)有index參數(shù)為當(dāng)前第幾張圖片

//自己處理
var span = document.getElementById('wapListImage').getElementsByTagName('dl')[0].getElementsByTagName('span');
for(var k = 0;k<span.length;k++){
span[k].className='';
}
span[obj.index-1].className='selected'
// console.log(obj.index)
}
};
WapImage.start(obj);
WapImage.position(2)

如果一個(gè)也沒(méi)需要多個(gè)圖片切換效果可以再代碼中查找 var loaded=function()

在其中定義您需要個(gè)切換圖片個(gè)數(shù)，并定出名字

如

w.WapImage=new WapImage();
w.WapImages=new WapImage();

在頁(yè)面加載完后就可以直接調(diào)用

WapImage.start()和WapImages.start()
