<A href="#" rel=red.css>Red Theme</A>
<A href="#" rel=blue.css>Blue Theme</A>
});
7. 列高度相同
如果使用了两个CSS列，使用此种方式可以是两列的高度相同。
$(document).ready(function() {
function equalHeight(group) {
tallest = 0;
group.each(function() {
thisHeight = $(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
// how to use
$(document).ready(function() {
equalHeight($(".left"));
equalHeight($(".right"));
});
});
8. 动态控制页面字体大小
用户可以改变页面字体大小
$(document).ready(function() {
// Reset the font size(back to default)
var originalFontSize = $('html').css('font-size');
$(".resetFont").click(function(){
$('html').css('font-size', originalFontSize);
});
// Increase the font size(bigger font0
$(".increaseFont").click(function(){
var currentFontSize = $('html').css('font-size');
var currentFontSizeNum = parseFloat(currentFontSize, 10);
var newFontSize = currentFontSizeNum*1.2;
$('html').css('font-size', newFontSize);
return false;
});
// Decrease the font size(smaller font)
$(".decreaseFont").click(function(){
var currentFontSize = $('html').css('font-size');
var currentFontSizeNum = parseFloat(currentFontSize, 10);
var newFontSize = currentFontSizeNum*0.8;
$('html').css('font-size', newFontSize);
return false;
});
});
9. 返回页面顶部功能
For a smooth(animated) ride back to the top(or any location).
$(document).ready(function() {
$('a[href*=#]').click(function() {
if (location.pathname.replace(/^//,'') == this.pathname.replace(/^//,'')
&& location.hostname == this.hostname) {
var $target = $(this.hash);
$target = $target.length && $target
|| $('[name=' + this.hash.slice(1) +']');
if ($target.length) {
var targetOffset = $target.offset().top;
$('html,body')
.animate({scrollTop: targetOffset}, 900);
return false;
}
}
});
// how to use
// place this where you want to scroll to
<A name=top></A>
// the link
<A href="#top">go to top</A>
});
10. 获得鼠标指针XY值
Want to know where your mouse cursor is?
$(document).ready(function() {
$().mousemove(function(e){
//display the x and y axis values inside the div with the id XY
$('#XY').html("X Axis : " + e.pageX + " | Y Axis " + e.pageY);
});
// how to use
<DIV id=XY></DIV>
});
11.返回顶部按钮
你可以利用 animate 和 scrollTop 来实现返回顶部的动画，而不需要使用其他插件。
// Back to top
$('a.top').click(function () {
$(document.body).animate({scrollTop: 0}, 800);
return false;
});
<!-- Create an anchor tag -->
