图像滑块不适用于ajax内容加载程序

标签: jquery ajax

当与我的ajax内容加载器结合使用时,我的图像滑块不起作用,但滑块单独工作。当我在我的网站上试用它时,图像滑块仅在刷新页面时有效。任何想法为什么这些都没有合作?

$(document).ready(function() {

//menu loader
$('.n3').click(function() {
  $('#secNav').toggle();
  return false;
});
$('.n1 a, .n2 a, .n4 a').click(function() {
  $('#secNav').hide();
});


//content loader in portfolio div      
var hash = window.location.hash.substr(1);
var href = $('.n1 a, .n2 a, .n4 a, #secNav a').each(function(){
    var href = $(this).attr('href');
    if(hash==href.substr(0,href.length-5)){
        var toLoad = hash+'.html #portfolio';
        $('#portfolio').load(toLoad)
    }                                           
});

$('.n1 a, .n2 a, .n4 a, #secNav a').click(function(){

var toLoad = $(this).attr('href')+' #portfolio';
$('#portfolio').fadeOut("fast",loadContent);
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5);
function loadContent() {
    $('#portfolio').load(toLoad,'',showNewContent())
}
function showNewContent() {
    $('#portfolio').fadeIn("1000");
}
return false;
});


//active link diff color

    $("#nav a").click( function() { 
              $("#nav a").css("color", "#000");
              $(this).css("color", "#85f1f5");
            });

$("#secNav a").click( function() { 
              $("#secNav a").css("color", "#000");
              $(this).css("color", "#ff2712");
            });

$("#nav a").click( function() { 
              $("#secNav a").css("color", "#000");
            });




//end of doc ready
});


//image slider

$(window).load(function(){

// We are listening to the window.load event, so we can be sure
// that the images in the slideshow are loaded properly.


// Testing whether the current browser supports the canvas element:

var slides = $('#slideshow li'),
    current = 0,
    slideshow = {width:0,height:0};

                // Taking the dimensions of the first image:
                slideshow.width = this.width;
                slideshow.height = this.height;

        // Depending on whether this is the next or previous
        // arrow, calculate the index of the next slide accordingly.

            nextIndex = current >= slides.length-1 ? 0 : current+1;
        }
        else {

        var next = slides.eq(nextIndex);

        if(supportCanvas){

            // This browser supports canvas, fade it into view:

            canvas.fadeIn(function(){

                // Show the next slide below the current one:

如果要用ajax替换一个新的滑块元素,则必须重新初始化滑块代码以处理新的html

伪代码示例

$('#sliderWrapper').load(  url, function(){

   /* new html exists, run all pertinent slider code*/
})

如果您删除所有不相关的代码(例如导航代码等)以解决与您的特定问题有关的内容,那将会有很大帮助。目前尚不清楚哪些部件与滑块相关

还要确保您没有再次加载jQuery并清除原始jQuery对象
