Seamless scrolling application (single or multiple lines) based on jQuery_jquery

Core jQuery code:

Copy code The code is as follows:

$(function(){
var _wrap=$('ul.line');//Define the scrolling area
var _interval=2000;//Define the scrolling gap time
var _moving;//Animation that needs to be cleared
_wrap.hover (function(){
clearInterval(_moving);//When the mouse is in the scroll area, stop scrolling
}, function(){
_moving=setInterval(function(){
var _field =_wrap.find('li:first');//This variable cannot be placed at the beginning of the function, the value of li:first changes
var _=_field.height();//Get each scroll Height (in the case of multi-line scrolling, this variable cannot be placed at the beginning, otherwise there will be an interval delay)
_field.animate({marginTop:-_h 'px'},600, function(){//pass Take a negative margin value and hide the first row
_field.css('marginTop',0).appendTo(_wrap);//After hiding, set the margin value of the row to zero and insert it to the end to achieve seamlessness scrolling
})
},_interval)//The scrolling interval depends on _interval
}).trigger('mouseleave');//When the function is loaded, mouseleave is simulated, that is, automatic scrolling
});
