我正在使用MSSQL 2005.

我有StringIO对象,其中包含我的zip文件内容.

以下是我获取zip二进制数据的方法:

    stringio = Zip::ZipOutputStream::write_buffer do |zio|
        Eclaim.find_by_sql("SET TEXTSIZE 67108864")
        zio.put_next_entry("application.xml")
        #zio.write @claim_db[:xml]
        biblio = Nokogiri::XML('<?xml version="1.0" encoding="utf-8"?>' + @claim_db[:xml], &:noblanks)
        zio.write biblio.to_xml

        builder = Nokogiri::XML::Builder.new(:encoding => 'utf-8') do |xml|
            xml.documents {
                docs.where("ext not in (#{PROHIBITED_EXTS.collect{|v| "'#{v}'"}.join(', ')})").each{|doc|
                    zio.put_next_entry("#{doc[:materialtitle_id]}.#{doc[:ext]}")
                    zio.write doc[:efile]

                    xml.document(:id => doc[:materialtitle_id]) {
                        xml.title doc[:title]
                        xml.code doc[:code]
                        xml.filename "#{doc[:materialtitle_id]}.#{doc[:ext]}"
                        xml.extname doc[:ext]
                    }

                }
            }
        end

        zio.put_next_entry("docs.xml")
        zio.write builder.to_xml
    end

    stringio

在我的控制器中我尝试:

data.rewind
@claim.docs.create(
    :title => 'Some file',
    :ext => 'zip', …

Mac OS X Lion 10.7.4

我正在使用Ipad 6.0 Simulator构建我的应用程序.

var pictureSource,
  destinationType;

function onDeviceReady() {
  pictureSource = navigator.camera.PictureSourceType;
  destinationType = navigator.camera.DestinationType;

  if (noConnection()) alert("No internet connection. Working in offline mode.");

  deviceId = device.uuid;

  initDb();
  initFileSystem();
}

 $("#take-photo").click(function(e){
    e.preventDefault();
    navigator.camera.getPicture(onPhotoUriSuccess,
      onPhotoFail,
      {quality: 85, destinationType: destinationType.FILE_URI}
    );
    return false;
  });

看起来一切都是正确但我得到一个错误'没有相机可用'.
也许是因为我正在运行我的应用程序wuth Ipad 6.0 Simulator.

我有Ipad 6.0模拟器和iOS设备可用于我的应用程序.当我选择iOS设备并运行时,我收到错误'没有配置的iOS设备可用兼容的iOS版本...'

如何让我的相机可用？

我想通过所有穿越日我的页面上的元素:

th元素的路径是div [id ='specs-list']/table/tbody/tr/th:

我的脚本是:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

driver.get('http://www.gsmarena.com');
driver.findElement(webdriver.By.name('sName')).sendKeys('iphone 4s');
driver.findElement(webdriver.By.id('quick-search-button')).click();


driver.findElement(webdriver.By.xpath("//div[@id='specs-list']/table/tbody/tr/th")).then(function(elem){
    console.log(elem.getText());
});

但我得到:

drobazko@drobazko:~/www$ node first_test.js
{ then: [Function: then],
  cancel: [Function: cancel],
  isPending: [Function: isPending] }

相反,文本General 问题是:
1.如何获得正确的文本字符串？
2.如何穿越的许多个要素是什么？
