我制作了一个jquery幻灯片,这里是代码:

HTML

<div id="slideshow">
    <img src="1.jpg">
    <img src="2.jpg">
    <img src="3.jpg">
</div>

<div id="previous">previous</div>

<div id="next">Next</div>

CSS

#slideshow {
    width: 700px;
    height: 400px;
    position: relative;
    overflow: hidden;
}

#slideshow img {
    position: absolute; 
}

jQuery的

$(document).ready(function() {
    $('#slideshow img:gt(0)').hide();

    $('#previous').click(function() {
        $('#slideshow img:first').fadeOut(1000).prev().fadeIn(1000).end().appendTo('#slideshow');
    });

    $('#next').click(function() {
        $('#slideshow img:first').fadeOut(1000).next().fadeIn(1000).end().appendTo('#slideshow');
    });
});

"下一步"按钮有效,但当我点击"上一个"时,图像消失了!谁能帮我？

这是 小提琴.

我有这个java类:

package myClass;
public class myClass 
{
    private int herAge ;
    public void setHerAge (int herAge)
    {
        this.herAge = herAge ; 
    }
}

我想在同一个目录中存在名为Test.java的另一个源文件中编译它之后导入这个类,这里​​Test.java包含:

import myClass ;
public class Test
{
    public static void main (String []args)
    {
    myClass Rudaina = new myClass();
    Rudaina.setHerAge(30);
    }
}

当我编译Test.java时,我在我的控制台中看到了这个:

Test.java:1: error '.' expected
import myClass ;
              ^
Test.java:1: error '.' expected
import myClass ;
                ^

我想读取一个数字作为字符串,并将其字符拆分为整数数组,并通过循环遍历整数数组找到它的数字之和.

到目前为止这是我的代码:

public static void main(String[] args) {
    Scanner S = new Scanner(System.in);
    String Number = S.next();
    int counterEnd = Number.length();
    int sum = 0 ;

    for ( int i = 0 ; i < counterEnd ; i++) {
         sum += sum + (Number.charAt(i));
    }

    System.out.println(sum);
}

不幸的是,此代码打印ASCII的总和而不是数字.

我用JavaScript制作了一个简单的数字时钟:

window.onload = function runMiniClock()
{
var time = new Date();
var hours = time.getHours();
var minutes = time.getMinutes();
minutes=((minutes < 10) ? "0" : "") + minutes;
ampm = (hours >= 12) ? "PM" : "AM";
hours=(hours > 12) ? hours-12 : hours;
hours=(hours == 0) ? 12 : hours;
var clock = hours + 1 + ":" + minutes + " " + ampm;
if(clock != document.getElementById('clock').innerHTML)
document.getElementById('clock').innerHTML = clock;
timer = setTimeout("runMiniClock()",1000);
setInterval(function(){
document.getElementById("clock").innerHTML = (new Date()).toLocaleTimeString(); …
