我的 javascript 无法在 IE8 中运行有一点问题。在 Firefox、ie9 和 chrome 中运行良好，但在 ie8 中运行良好。我知道这与准备在 ie8 中以不同方式工作的文档有关，但我找不到答案。请参阅下面的代码。
// JavaScript Document
/* Set Opacity to 0 for all list items that do not have class show
This prevents the gallery animation from jumping around unexpectedly.
*/
function clearShowClass() {
setTimeout(timedInterval, 1000);
};
function timedInterval() {
$('ul.slideshow li').not('.show').css("opacity", 0);
clearShowClass();
};
function slideShow(speed) {
//Call the gallery function to run the slideshow
var timer = setInterval('gallery()', speed);
//Pause the slideshow on mouse over content
$('#footer, ul.slideshow').hover(
function () {
clearInterval(timer);
},
function () {
timer = setInterval('gallery()', speed);
});
} // End of slideshow
/* Slideshow gallery main images */
function gallery() {
//if no IMGs have the show class, grab the first image
var current = ($('ul.slideshow li.show') ? $('ul.slideshow li.show') : $('#ul.slideshow li.first'));
//Get next image, if it reached the end of the slideshow, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().attr('id') == 'slideshow-caption') ? $('ul.slideshow li:first') : current.next()) : $('ul.slideshow li:first'));
//Set the fade in effect for the next image, show class has higher z-index
next.css({
opacity: 4.0
}).addClass('show').animate({
opacity: 4.0
}, 1000);
// Hide the current image
current.animate({
opacity: 0.0
}, 1000).removeClass('show');
//if no thumbnails have the highlight class, grab the first thumbnail
var currentThumb = ($('#footer li.highlight') ? $('#footer li.highlight') : $('#footer li:first'));
var nextThumb = ($('#footer li:last').hasClass('highlight')) ? $('#footer li:nth-child(1)') : $('#footer li.highlight').next($('#footer li'));
nextThumb.addClass('highlight');
currentThumb.removeClass('highlight');
}; // End of Gallery
function thumbInt() {
for (i = 1; i <= $('ul.slideshow li').length; i++) {
$('#footer .thumbnail' + i).bind('click', {
iteration: i
}, function (event) {
$('ul.slideshow li').removeClass('show').css("opacity", 0).add($('ul.slideshow li:nth-child(' + event.data.iteration + ')').addClass('show').css("opacity", 0.0).animate({
opacity: 1.0
}, 1000));
$('#footer li').removeClass('highlight').add($('#footer li:nth-child(' + event.data.iteration + ')').addClass('highlight').add($('#footer li:nth-child(' + event.data.iteration + ') img')));
});
};
};
var prmEnd = Sys.WebForms.PageRequestManager.getInstance();
prmEnd.add_endRequest(function () {
thumbInt(); // Assign int to thumbnail list items
clearShowClass(); // Prevents multiple li having .show
$('#footer img').mouseover(
function () {
$(this).animate({
opacity: 3.7
})
});
$('#footer img').mouseout(
function () {
$(this).animate({
opacity: 0.7
})
});
//Set the opacity of all images to 0
$('ul.slideshow li').css({
opacity: 0.0
});
//Get the first image and display it (set it to full opacity)
$('ul.slideshow li:first').css({
opacity: 1.0
}).addClass('show');
//Get the first thumbnail and change css
$('#footer li:first').css({
opacity: 1.0
}).addClass('highlight');
});
$(document).ready(function () {
slideShow(6000);
thumbInt(); // Assign int to thumbnail list items
clearShowClass(); // Prevents multiple li having .show
$('#footer img').mouseover(
function () {
$(this).animate({
opacity: 3.7
})
});
$('#footer img').mouseout(
function () {
$(this).animate({
opacity: 0.7
})
});
});
此页面的工作方式是用户单击单选按钮以触发 _dopostback 并显示图像库。问题是当我执行 _dopostback 时，文档就绪代码不再起作用，但这仅发生在 ie8 中。我正在使用 Sys.WebForms.PageRequestManager.getInstance(); 在我的更新面板中更新后运行的代码。
谢谢。
