我试图在JavaScript中返回两个值.那可能吗？

var newCodes = function() {  
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    return dCodes, dCodes2;
};

我有一个HTML表单字段$_POST["url"],其中包含一些URL字符串作为值.示例值为:

https://example.com/test/1234?email=xyz@test.com
https://example.com/test/1234?basic=2&email=xyz2@test.com
https://example.com/test/1234?email=xyz3@test.com
https://example.com/test/1234?email=xyz4@test.com&testin=123
https://example.com/test/the-page-here/1234?someurl=key&email=xyz5@test.com

等等

如何email从这些URL /值中仅获取参数？

请注意,我没有从浏览器地址栏中获取这些字符串.

如何使用jQuery检查下拉菜单中有多少选项？

谢谢.

如何07/26/2010使用Javascript 转换为UNIX时间戳？

我有一个像这样的选择语句

select field1, field2  
  from table1

我想要的是拥有一个只有值"example"的新字段.

newfield 表中不存在,但是当我运行此查询时,它会使用示例字段的值创建一个虚拟列.

我有一个有日期输入的表

<td style="background-color:#c6efce"><input type="text" id="datepicker0"></td>
<td style="background-color:#c6efce"><input type="text" id="datepicker1"></td>
<td style="background-color:#c6efce"><input type="text" id="datepicker2"></td>
<td style="background-color:#c6efce"><input type="text" id="datepicker3"></td>
<td style="background-color:#c6efce"><input type="text" id="datepicker4"></td>

我试图通过第一个访问它

<script>
    $(function() {
        $( "#datepicker0" ).datepicker({
            showButtonPanel: true
        });
    });
    </script>

我如何访问所有内容？

我在让旋转木马正常工作方面遇到问题.我用yeomen来支撑角应用程序.我收到了这个错误

我是CakePHP的新手.我想读取控制器中表的字段名称.

我希望控制器列出表中的所有字段名称.我怎么做？

我正在使用这个

for($number=0; $number < 5; $number++){
StreamWriter x = new StreamWriter("C:\\test.txt");
                x.WriteLine(number);
                x.Close();

}

如果某些内容在test.text中,则此代码不会覆盖它.我有两个问题

1: how can I make it overwrite the file
2: how can I append to the same file

使用C#

我正在玩节点,只是将它安装在我的机器上.现在我想得到一个在我的机器上运行的进程列表,这样我就可以看到Apache是​​否正在运行,MySQL是否已启动等等？我怎样才能做到这一点？我在js文件中只有非常基本的代码.我甚至不知道从哪里开始.

这是我的代码:

var http = require('http');
http.createServer(function(request, response){
    response.writeHead(200);
    response.write("Hello world");
    console.log('Listenning on port 1339');
    response.end();
}).listen(8080);
