一开始我在头中加载了所有的js脚本,一切都正常。但我有一个js文件需要内联加载/只在某个页面中加载。
这是我需要加载的js文件
var myScroll,pullDownEl, pullDownOffset, generatedCount = 0;
function pullDownAction () {
setTimeout(function () {
var el, li, i;
el = document.getElementById('newlist');
if ( el.hasChildNodes() ) {
while ( el.childNodes.length >= 1 ) {
el.removeChild( el.firstChild );
}
}
for (i=0; i<6; i++) {
li = document.createElement('li');
li.innerText = 'Generated row ' + (++generatedCount);
el.insertBefore(li, el.childNodes[0]);
}
myScroll.refresh();
}, 1000);
}
function loaded() {
pullDownEl = document.getElementById('pullDown');
pullDownOffset = pullDownEl.offsetHeight;
myScroll = new iScroll('wrapper', {
//hideScrollbar: false,
//hScrollbar: false, vScrollbar: false, vScroll: false,
useTransition: true,
topOffset: pullDownOffset,
onRefresh: function () {
if (pullDownEl.className.match('loading')) {
pullDownEl.className = '';
pullDownEl.querySelector('.pullDownLabel').innerHTML = 'Pull down to refresh...';
$('#pullDown').css('display', 'inherit');
$('#pullDown').css('display', 'none');
$('#thelist').css('display', 'none');
$('#newlist').css('display', 'inherit');
}
},
onScrollMove: function () {
if (this.y > 5 && !pullDownEl.className.match('flip')) {
pullDownEl.className = 'flip';
pullDownEl.querySelector('.pullDownLabel').innerHTML = 'Release to refresh...';
$('#pullDown').css('display', 'inherit');
this.minScrollY = 0;
} else if (this.y < 5 && pullDownEl.className.match('flip')) {
pullDownEl.className = '';
pullDownEl.querySelector('.pullDownLabel').innerHTML = 'Pull down to refresh...';
$('#pullDown').css('display', 'inherit');
this.minScrollY = -pullDownOffset;
}
},
onScrollEnd: function () {
if (pullDownEl.className.match('flip')) {
pullDownEl.className = 'loading';
pullDownEl.querySelector('.pullDownLabel').innerHTML = 'Loading...';
pullDownAction();
}
}
});
setTimeout(function () { document.getElementById('wrapper').style.left = '0'; }, 800);
}
document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
document.addEventListener('DOMContentLoaded', function () { setTimeout(loaded, 200); }, false);
将它与我的头中的其他脚本一起加载,它可以工作,但现在我使用的是jquery getScript。它加载了脚本(使用firebug),但当我尝试调用js文件中的函数时,它给了我两个错误
无法读取空的属性"offsetHeight"
无法调用未定义的方法"刷新"
这就是我使用getScript 调用js脚本的方式
$(document).ready(function() {
$('.email').click(function (){
$.getScript("assets/js/scroll.js",function() {
pullDownAction();
loaded();
});
});
});
帮助任何
我知道这可能意味着要做比你想做的更多的工作,但你试过做名称空间调整吗?我不知道这是否100%有效(因为我不确定为什么这对你不起作用),但你尝试过吗?
(function( PullDown, $, undefined ) {
//Private variables and this is a great way for minification, you will get the most out of it
var myScroll,pullDownEl, pullDownOffset, generatedCount = 0;
function pullDownAction () {
//... your stuff here
}
function loaded() {
//... more your stuff here
}
}(window.PullDown = window.PullDown || {}, jQuery) // avoids name space collision w/ jQuery
现在做同样的事情,但这次编辑。
$(document).ready(function() {
$('.email').click(function (){
$.getScript("assets/js/scroll.js",function() {
window.PullDown.pullDownAction();
window.PullDown.loaded();
});
});
});
如果我没有错,或者复制粘贴技术不好,这应该很好!
