8个实用的jQuery技巧

 $(‘#top’).click(function() {
  //scoll the page back to the top
  $(document).scrollTo(0,500);
 }
});
6）获取鼠标指针的X / Y轴
$().mousemove(function(e){
    //display the x and y axis values inside the P element
    $(‘p’).html(“X Axis : ” + e.pageX + ” | Y Axis ” + e.pageY);
});
7）检测当前鼠标坐标
使用这个脚本，你可以在任何网络浏览器获取鼠标坐标。
$(document).ready(function() {
$().mousemove(function(e)
{
    $(‘# MouseCoordinates ‘).html(“X Axis Position = ” + e.pageX + ” and Y Axis Position = ” + e.pageY);
});
8）图片预加载
此段代码帮助用户快速加载图片或网页页面。

jQuery.preloadImagesInWebPage = function()
{
     for(var ctr = 0; ctr<arguments.length; ctr++)
     {
         jQuery(“”).attr(“src”, arguments[ctr]);
     }
}
To use the above method, you can use the following piece of code:
$.preloadImages(“image1.gif”, “image2.gif”, “image3.gif”);
To check whether an image has been loaded, you can use the following piece of code:
$(‘#imageObject’).attr(‘src’, ‘image1.gif’).load(function() {
    alert(‘The image has been loaded…’);
});
