小编Mik*_*ike的帖子

我目前正在寻找一种方法来加载多个脚本/插件,而无需在标题中列出清单.

要简单地拥有一个load.js,所有加载对我来说都是非常优雅的.

$(function() {
    var scripts = ['scripts/jquery1.5.js','scripts/easing.js','scripts/scroll.js','scripts/main.js'];

    for(var i = 0; i < scripts.length; i++) {
        $.getScript(scripts[i]);
    }
})

我目前有类似的东西,但由于某种原因无法让它工作.有任何想法吗？

这是我的代码

public class Main extends Activity {  

    @Override  
    public void onCreate(Bundle savedInstanceState)  
    {  
        super.onCreate(savedInstanceState);   
        LinearLayout rLinear=new LinearLayout(this);  
        rLinear.setId(200);  

        for (int c=0;c<5;c++)  
        {  
            ImageView imEdit = new ImageView(this);  
            imEdit.setId(300+c);  
            imEdit.setImageResource(R.drawable.a);  
            imEdit.setLayoutParams(new LayoutParams(36, 36));  

            rLinear.addView(imEdit);
        }
    }  
}  

好吧,我有这个代码,我在运行时添加5个ImageView到线性布局,到目前为止一直很好,但我想做的是,当用户将手指滑过其中一个时,我想改变图像,所以我的问题是,我怎么知道用户手指下的当前图像视图是什么.

谢谢.

我的错误日志失控,出现以下两个错误

warning feof() expects parameter 1 to be resource

和

warning fread() expects parameter 1 to be resource

负责的代码是

<?php
    $file = '../upload/files/' . $filex;
    header("Content-Disposition: attachment; filename=" . urlencode($file));
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header("Content-Description: File Transfer");
    header("Content-Length: " . filesize($file));
    flush(); // this doesn't really matter.

    $fp = fopen($file, "r");
    while (!feof($fp)) {
        echo fread($fp, 65536);
        flush(); // this is essential for large downloads
    }
    fclose($fp);
?> 

我使用这个代码进行标题下载,但它现在吓坏了 - 在任何人询问我尝试过之前,我试过google但仍然不完全理解错误消息.

Mysql错误日志旁边只有一个数字和它们的创建时间，我需要对其进行格式设置，以便它还包括日期，

我该怎么办？

每当我执行我的程序时,我都会收到以下错误.我已正确安装模块,但我不知道为什么会出现此错误.

我想知道是否有人能帮助我解决我遇到的一个小的html/css问题.基本上,我正在尝试使用不同的图像为每个列表项的项目创建一个无序列表,并在同一行的右侧显示文本.更具体地说,顶行的标题和下面的一些普通文本.目前,我可以将图像和文本放在同一行:-(这是我的代码.

任何帮助将不胜感激.

HTML:

<ul>
    <li class="service-list">
        <a href=""><img src="image.png" alt="icon" class="alignnone size-full wp-image-156" /></a>
        <h3>Header</h3>
        <p>
        text goes here
        </P>
    </li>
....
</ul>

CSS:

.service-list {
    list-style-type: none;
    margin-left:0px;
    padding-left:0px;
    float: left;
    display: inline-block;
}


.service-list p {
    text-align: right; 
    margin: 0; 
    padding: 0;
}

我不明白为什么__unset()不工作.

class myclass {
    public $name = array();

    public function __set($arraykey, $value){
        $this->name[$arraykey] = $value;
    }

    public function __isset($argu){
        return isset($this->name[$argu]);
    }

    public function __unset($argu){ 
        echo "Working: Unset $this->name[$argu]";
        unset($this->name[$argu]);
    }
}

$obj = new myclass;
$obj->name = 'Arfan Haider';

var_dump(isset($obj->name));

unset($obj->name);

我读到只要unset()调用该函数,就会__unset()自动调用Magic Method 并取消设置变量.

在上面的代码我使用unset但它没有调用__unset().为什么？我在理解魔术方法时遗漏了什么__unset()？

我想从选择中将数据插入到表中。到目前为止，这工作正常......

INSERT INTO table_2
    SELECT t.id, 1
        FROM table_1 t
        WHERE t.title LIKE '%search%';

但是当我第二次运行时，该语句引发异常，因为某些行已经存在。

我能做些什么来解决这个问题？

感谢您的帮助，乌克曼

var xmlhttp;
if (window.XMLHttpRequest) {
    xmlhttp=new XMLHttpRequest();
}
else {
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

xmlhttp.open("POST","test.php",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send("abc=123");

xmlhttp.onreadystatechange = function() {
    if (xmlhttp.readyState==4 && xmlhttp.status==200) {

        <?php if(isset($_POST['abc'])) {
            $test123 = 'worked';
        }
    ?>

}}
var worked = '<?php echo $test123;?>'; // <--- this is not working

我怎样才能做到这一点？我不会在PHP中收到变量,无论是使用get还是post方法.

我试图弄清楚这个程序是如何工作的,我陷入了While循环,我不明白第二个循环如何退出,因为它v永远不会等于0或负数.既然这是唯一可以退出该循环的条件,还是我错过了更深层次的东西？代码将整数(> 0)转换为二进制.

public class Binary { 
public static void main(String[] args) { 

    // read in the command-line argument
    int n = Integer.parseInt(args[0]);

    // set v to the largest power of two that is <= n
    int v = 1;
    while (v <= n/2) {
        v = v * 2;
    }

    // check for presence of powers of 2 in n, from largest to smallest
    while (v > 0) {

        // v is not present in n 
        if (n …
