MessageBox ?

[doug1]

Hi,

Is there a way to pop up a text message box with "OK" on it in EFS? Javascript has the window.alert function but it appears not to be supported in EFS. Any other ideas?

I would like to pop up a messagebox or msgbox like windows.

Thanks,
Doug

I don't think there is any way to do that (though I would need to look at one possible work around first), but can you tell me what you are trying to do...why you want the message box?

I want to add it to my strategy so that every time my strategy has a new order, I can pop up the order on my screen and play a sound to alert me.

Hello Doug,

window.alert() is a browser extension and is not part of core JavaScript. The only thing we have in EFS that is similar would be askForInput() function, which brings up the formula parameters window.

Alternatively, you could use the drawTextRelative() or drawTextAbsolute() functions to print some text on the chart. You could then assign an EFS function to the text object that would remove the text from the chart when you click on it. Try something this:

message.efs

function preMain() {
    setStudyTitle(" Remove Message Example");
    setShowCursorLabel(false);
}

var TagName = null;
function main() {
    if (getCurrentBarIndex() == -1) {
        TagName = "error";
        drawTextAbsolute( 15, 15, "Message - click to remove @URL=EFS:removeIt",
            Color.white, Color.red, Text.RELATIVETOLEFT|Text.RELATIVETOBOTTOM|Text.CENTER,
            null, 14, TagName);
    }
}

function removeIt() {
    removeText(TagName);
}
