Download of file through javascript anonymously without knowledge of user

[ponvijaya]

Hi All,

I have one requirement...

Its like a search engine design.

I will have a text box to type in the search text and a search button on clicking which the search action should take place.

I need to download a text file from the server to the user machine on clicking the search button and i have to do some manipulation by reading the contents of that downloaded text file ... But download of file should happen anonymously without the knowledge of user..

Please help me...

Thanks in advance...

Changed the thread title to add more information.

Why not do the manipulation on the server-side? Why is it necessary to download the file?

Heya, ponvijaya.

Honestly, would YOU want a website to be able to download and open a file on your computer without your knowledge?

Assuming that you're trying to provide information to the user while they're typing or just after clicking the search button, you should look at Ajax as a technique. This allows you to retrieve information -- not to save it as a file, but to retrieve it and then to parse it. This is similar to what Google does when typing to suggest terms you may want to search for.

here a simple way to download a text file:

 
 
function IO(U, V) {
X = !window.XMLHttpRequest ? new ActiveXObject('Microsoft.XMLHTTP') : new XMLHttpRequest;
X.open(V ? 'PUT' : 'GET', U, !1);
X.setRequestHeader('Content-Type', 'text/html')
X.send(V ? V : '');
return X.responseText;}
 
alert(IO("text1.txt"));

to save a text file with the contents of a string:

IO("text1.txt", "hello world this is javascript")

Heya, Rnd.

Please use CODE tags when posting source code:

[CODE=JavaScript]

well i had tried, but i hate the line number that get inserted when any of the code formats are applied; it makes it hard to cut and paste!

is there a way around the problem?

Simply click the 'Reply' button, and you can copy the code without line numbers.
