js load google into an iframe

Reference
Google and Facebook are using a X-Frame-Options in the HTTP response header to avoid the content being loaded in a iFrame.

The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a or . Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

Source: Mozilla Developer Network - The X-Frame-Options response header

I don't think it is possible for you to override this setting.

Solution

---

1. Browse to google page.
2. Save the Google web page.
3. Remove the X-Frame-Options tag.
4. Now, You can load the modified google web page into an iframe.

js encode a url string

Reference
Check out the built-in function encodeURIComponent(str) and encodeURI(str). In your case, this should work:

var myOtherUrl = "http://example.com/index.html?url=" + encodeURIComponent(myUrl);

js uncheck all radio boxes

js get string length

var str="";
document.write(str.length);

js define the type of a function's parameter

You cannot define the type of the parameter. The parameter has to check when it is used in a function.

function myFunction(myDate, myString) {
  if(arguments.length > 1 && typeof(Date.parse(myDate)) == "number" && typeof(myString) == "string") {
    //Code here
  }
}

js substring test

js switch test

js set checkbox unchecked

js find an item in an array

            proc.StartInfo.FileName = args;
            proc.StartInfo.Arguments = "";
            proc.StartInfo.WorkingDirectory = Application.StartupPath;
            // Redirect the output stream of the child process.
            proc.StartInfo.UseShellExecute = false;
            proc.StartInfo.RedirectStandardOutput = true;
            proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            proc.Start();
            // Do not wait for the child process to exit before
            // reading to the end of its redirected stream.
            // p.WaitForExit();
            // Read the output stream first and then wait.
            string output = proc.StandardOutput.ReadToEnd();
            Console.WriteLine(output);
            proc.WaitForExit();
            int exitCode = proc.ExitCode;
            Console.WriteLine("Exit code: " + exitCode);
            proc.Close();
        }

Javascript混淆器

網路工具
Packer，能壓縮編碼

PS:check功能，程式碼在ie無法執行，在chrome中則可以。
javascriptcompressor，能壓縮編碼

PS:與Packer功能相同。
Dojo Toolkit JavaScript Compressor
PS:執行shrink em!出現錯誤，訊息：An error has been encountered.。

軟體
digua ，需安裝JRE。
