//1. Truncate a string
function truncate{
var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10).split(" ").slice(0, -1).join(" ") + "...";
alert(shortText );
}

//2. Mouse Event
function mouseoverAndmouseout()
{
$( "p" ).bind( "mouseenter mouseleave", function( event ) {
$( this ).toggleClass( "over" );
});

$( "li" ).hover(
function() {
$( this ).append( $( "<span> ***</span>" ) );
}, function() {
$( this ).find( "span:last" ).remove();
}
);

$('li').hover(
function(){
$(this).append();
}, function(){
$(this).find().remove();
}
);
}

//3. jQuery弹出层始终垂直居中
function popup(popupName){
var _scrollHeight = $(document).scrollTop(),//获取当前窗口距离页面顶部高度
_windowHeight = $(window).height(),//获取当前窗口高度
_windowWidth = $(window).width(),//获取当前窗口宽度
_popupHeight = popupName.height(),//获取弹出层高度
_popupWeight = popupName.width();//获取弹出层宽度
_posiTop = (_windowHeight - _popupHeight)/2 + _scrollHeight;
_posiLeft = (_windowWidth - _popupWeight)/2;
popupName.css({"left": _posiLeft + "px","top":_posiTop + "px","display":"block"});//设置position
}
$(function(){
$(".btn1").click(function(){
popup($("#div1"));
});
$(".btn2").click(function(){
popup($("#div2"));
});
});

//4. jquery获取对象坐标

function getPosition()
{
//获取页面某一元素的绝对X,Y坐标，可以用offset()方法：

var X = $('#DivID').offset().top;
var Y = $('#DivID').offset().left;

//获取相对(父元素)位置:

var X = $('#DivID').position().top;
var Y = $('#DivID').position().left;
}

//5. to make the child element a drag handle
//<div class="parent">
//<divc class="draggable"></div>
//</div>
function childDrag()
{
$(".parent").draggable({ handle: ".draggable" });
