ios瀏覽器調試踩坑（1）----mescroll.js和vue-scroller

主要記錄在ios瀏覽器出現觸摸無限載入的情況

使用vue-scroller和mescroll.js/mescroll.vue先踩ios瀏覽器預設滑動會影響mescroll的方法調用。

首先給公共js加入以下代碼禁用我們的頁面在ios瀏覽器下會滑動上下頁面。

<script>
//禁止ios手機雙擊放大以及縮小
window.onload = function () {
// 阻止雙擊放大
var lastTouchEnd = 0;
document.addEventListener('touchstart', function (event) {
if (event.touches.length > 1) {
event.preventDefault();
}
});
document.addEventListener('touchend', function (event) {
var now = (new Date()).getTime();
if (now - lastTouchEnd <= 300) {
event.preventDefault();
}
lastTouchEnd = now;
}, false);

// 阻止雙指放大
document.addEventListener('gesturestart', function (event) {
event.preventDefault();
});



//在ios瀏覽器調試的時候禁止頁面滾動
var ios = navigator.userAgent.indexOf('iPhone');//判斷是否為ios
if (ios != -1) {
//ios下運行
var scroll = document.getElementById("scroll")//你需要滑動的dom元素
touchScroll(scroll);
}

var canScroll = true;
function touchScroll(el) {
canScroll = false;
//el需要滑動的元素
el.addEventListener('touchmove', function (e) {
canScroll = true;
})
document.body.addEventListener('touchmove', function (e) {
//       alert(canScroll);
if (!canScroll) {
e.preventDefault(); //阻止預設事件(上下滑動)
} else {
//需要滑動的區域
var top = el.scrollTop; //對象最頂端和視窗最頂端之間的距離
var scrollH = el.scrollHeight; //含滾動內容的元素大小
var offsetH = el.offsetHeight; //網頁可見區域高
var cScroll = top + offsetH; //當前滾動的距離

//被滑動到最上方和最下方的時候
if (top == 0) {
top = 1; //0～1之間的小數會被當成0
} else if (cScroll === scrollH) {
el.scrollTop = top - 0.1;
}
}
}, { passive: false }) //passive防止阻止預設事件不生效
}
}
