Reading in files using JS

Michif

Hi all,

I am wondering whether there is a way to load in a file (.txt, .cvs or .JSON) using javascript in the inline_javascript item. Whether the file is from a different server or just from the file pool does not matter for me.

Is this possible?

Thanks,

M

Hi @Michif ,

This recipe from stackoverflow should allow you read text from a file through a URL. However, this file will probably need to be placed on the same server as the experiment, otherwise it will likely be blocked as a security measure. But maybe it's useful anyway.

function getText(url){
    // read text from URL location
    var request = new XMLHttpRequest();
    request.open('GET', url, true);
    request.send(null);
    request.onreadystatechange = function () {
        if (request.readyState === 4 && request.status === 200) {
            var type = request.getResponseHeader('Content-Type');
            if (type.indexOf("text") !== 1) {
                return request.responseText;
            }
        }
    }
}

vars.my_text = getText('http://www.puzzlers.org/pub/wordlists/pocket.txt')
console.log(vars.my_text)

I'm also thinking about a way to allow access to files in the file pool in OSWeb. But for now that's not possible!
