javascript 移动盒子的自动播放
请访问:http://gati.simptome-remedii.ro/。正如您所看到的,标题中有一个轮播效果,一旦您单击箭头或按左/右键,它就会向前和向后移动。 我需要它自动播放,所以我需要自动滑动效果。 时间间隔应该是5秒(我想我可以稍后设置)。
此轮播效果使用 jquery-1.3.1.min.js 和 slider.js 。
Slider.js
$(function() {
var totalPanels = $(".scrollContainer").children().size();
var regWidth = $(".panel").css("width");
var regImgWidth = $(".panel img").css("width");
var regTitleSize = $(".panel h2").css("font-size");
var regParSize = $(".panel p").css("font-size");
var movingDistance = 300;
var curWidth = 350;
var curImgWidth = 220;
var curTitleSize = "15px";
var curParSize = "15px";
var $panels = $('#slider .scrollContainer > div');
var $container = $('#slider .scrollContainer');
$panels.css({'float' : 'left','position' : 'relative'});
$("#slider").data("currentlyMoving", false);
$container
.css('width', ($panels[0].offsetWidth * $panels.length) + 100 )
.css('left', "-350px");
var scroll = $('#slider .scroll').css('overflow', 'hidden');
function returnToNormal(element) {
$(element)
.animate({ width: regWidth })
.find("img")
.animate({ width: regImgWidth })
.end()
.find("h2")
.animate({ fontSize: regTitleSize })
.end()
.find("p")
.animate({ fontSize: regParSize });
};
function growBigger(element) {
$(element)
.animate({ width: curWidth })
.find("img")
.animate({ width: curImgWidth })
.end()
.find("h2")
.animate({ fontSize: curTitleSize })
.end()
.find("p")
.animate({ fontSize: curParSize });
}
//direction true = right, false = left
function change(direction) {
//if not at the first or last panel
if((direction && !(curPanel < totalPanels)) || (!direction && (curPanel <= 1))) { return false; }
//if not currently moving
if (($("#slider").data("currentlyMoving") == false)) {
$("#slider").data("currentlyMoving", true);
var next = direction ? curPanel + 1 : curPanel - 1;
var leftValue = $(".scrollContainer").css("left");
var movement = direction ? parseFloat(leftValue, 10) - movingDistance : parseFloat(leftValue, 10) + movingDistance;
$(".scrollContainer")
.stop()
.animate({
"left": movement
}, function() {
$("#slider").data("currentlyMoving", false);
});
returnToNormal("#panel_"+curPanel);
growBigger("#panel_"+next);
curPanel = next;
//remove all previous bound functions
$("#panel_"+(curPanel+1)).unbind();
//go forward
$("#panel_"+(curPanel+1)).click(function(){ change(true); });
//remove all previous bound functions
$("#panel_"+(curPanel-1)).unbind();
//go back
$("#panel_"+(curPanel-1)).click(function(){ change(false); });
//remove all previous bound functions
$("#panel_"+curPanel).unbind();
}
}
// Set up "Current" panel and next and prev
growBigger("#panel_3");
var curPanel = 3;
$("#panel_"+(curPanel+1)).click(function(){ change(true); });
$("#panel_"+(curPanel-1)).click(function(){ change(false); });
//when the left/right arrows are clicked
$(".right").click(function(){ change(true); });
$(".left").click(function(){ change(false); });
$(window).keydown(function(event){
switch (event.keyCode) {
case 13: //enter
$(".right").click();
break;
case 32: //space
$(".right").click();
break;
case 37: //left arrow
$(".left").click();
break;
case 39: //right arrow
$(".right").click();
break;
}
});
}
);
我真的很期待收到答案。
谢谢 !
问候, 拉兹万。
Please go to : http://gati.simptome-remedii.ro/ . As you can see there is a carousel effect in the header and it goes forward and backwards once you click on the arrows or press left/right key .
I need it to autoplay so I need an autosliding effect.
Time interval should be 5 seconds ( I guess I can set that up later ) .
This carousel effect uses jquery-1.3.1.min.js and slider.js .
Slider.js
$(function() {
var totalPanels = $(".scrollContainer").children().size();
var regWidth = $(".panel").css("width");
var regImgWidth = $(".panel img").css("width");
var regTitleSize = $(".panel h2").css("font-size");
var regParSize = $(".panel p").css("font-size");
var movingDistance = 300;
var curWidth = 350;
var curImgWidth = 220;
var curTitleSize = "15px";
var curParSize = "15px";
var $panels = $('#slider .scrollContainer > div');
var $container = $('#slider .scrollContainer');
$panels.css({'float' : 'left','position' : 'relative'});
$("#slider").data("currentlyMoving", false);
$container
.css('width', ($panels[0].offsetWidth * $panels.length) + 100 )
.css('left', "-350px");
var scroll = $('#slider .scroll').css('overflow', 'hidden');
function returnToNormal(element) {
$(element)
.animate({ width: regWidth })
.find("img")
.animate({ width: regImgWidth })
.end()
.find("h2")
.animate({ fontSize: regTitleSize })
.end()
.find("p")
.animate({ fontSize: regParSize });
};
function growBigger(element) {
$(element)
.animate({ width: curWidth })
.find("img")
.animate({ width: curImgWidth })
.end()
.find("h2")
.animate({ fontSize: curTitleSize })
.end()
.find("p")
.animate({ fontSize: curParSize });
}
//direction true = right, false = left
function change(direction) {
//if not at the first or last panel
if((direction && !(curPanel < totalPanels)) || (!direction && (curPanel <= 1))) { return false; }
//if not currently moving
if (($("#slider").data("currentlyMoving") == false)) {
$("#slider").data("currentlyMoving", true);
var next = direction ? curPanel + 1 : curPanel - 1;
var leftValue = $(".scrollContainer").css("left");
var movement = direction ? parseFloat(leftValue, 10) - movingDistance : parseFloat(leftValue, 10) + movingDistance;
$(".scrollContainer")
.stop()
.animate({
"left": movement
}, function() {
$("#slider").data("currentlyMoving", false);
});
returnToNormal("#panel_"+curPanel);
growBigger("#panel_"+next);
curPanel = next;
//remove all previous bound functions
$("#panel_"+(curPanel+1)).unbind();
//go forward
$("#panel_"+(curPanel+1)).click(function(){ change(true); });
//remove all previous bound functions
$("#panel_"+(curPanel-1)).unbind();
//go back
$("#panel_"+(curPanel-1)).click(function(){ change(false); });
//remove all previous bound functions
$("#panel_"+curPanel).unbind();
}
}
// Set up "Current" panel and next and prev
growBigger("#panel_3");
var curPanel = 3;
$("#panel_"+(curPanel+1)).click(function(){ change(true); });
$("#panel_"+(curPanel-1)).click(function(){ change(false); });
//when the left/right arrows are clicked
$(".right").click(function(){ change(true); });
$(".left").click(function(){ change(false); });
$(window).keydown(function(event){
switch (event.keyCode) {
case 13: //enter
$(".right").click();
break;
case 32: //space
$(".right").click();
break;
case 37: //left arrow
$(".left").click();
break;
case 39: //right arrow
$(".right").click();
break;
}
});
}
);
I am really looking forward to receiving an answer.
Thank you !

简单的事情就是这样做,
这将每 5 秒调用一次单击右侧按钮。
但是,如果您希望它向左和向右移动,则需要添加一些逻辑。
更新
试试这个(把它放在
$(window).keydown
行之前..)The simple thing would be to do
This will call click the right button every 5 seconds..
But you will need to add some logic if you want it to go both left and right ..
update
Try this (put it right before the
$(window).keydown
line ..)
