我想让我的身体在使用鼠标滚轮时停止滚动,而我的网站上的Modal(来自http://twitter.github.com/bootstrap)是打开的。
当模式被打开时,我试图调用下面的javascript片段,但没有成功
$(window).scroll(function() { return false; });
AND
$(window).live('scroll', function() { return false; });
请注意,我们的网站放弃了对IE6的支持,IE7+需要兼容。
试试下面的代码:
$('.entry_details').dialog({
width:800,
height:500,
draggable: true,
title: entry.short_description,
closeText: "Zamknij",
open: function(){
// blokowanie scrolla dla body
var body_scroll = $(window).scrollTop();
$(window).on('scroll', function(){
$(document).scrollTop(body_scroll);
});
},
close: function(){
$(window).off('scroll');
}
});
/* =============================
* Disable / Enable Page Scroll
* when Bootstrap Modals are
* shown / hidden
* ============================= */
function preventDefault(e) {
e = e || window.event;
if (e.preventDefault)
e.preventDefault();
e.returnValue = false;
}
function theMouseWheel(e) {
preventDefault(e);
}
function disable_scroll() {
if (window.addEventListener) {
window.addEventListener('DOMMouseScroll', theMouseWheel, false);
}
window.onmousewheel = document.onmousewheel = theMouseWheel;
}
function enable_scroll() {
if (window.removeEventListener) {
window.removeEventListener('DOMMouseScroll', theMouseWheel, false);
}
window.onmousewheel = document.onmousewheel = null;
}
$(function () {
// disable page scrolling when modal is shown
$(".modal").on('show', function () { disable_scroll(); });
// enable page scrolling when modal is hidden
$(".modal").on('hide', function () { enable_scroll(); });
});
