Validate a file exists

Question

I want to validate the existence of a HTML file before opening it in a new tab.

How can I do so using pure JavaScript?

I am storing the file's location in path variable.

path = "F:\Folder_JS\File1.html";
//I want to check here whether there exists such a file or not before opening it new tab
myWindow = window.open(path,'_blank');

You may try it by js:

var url = 'File1.html'; //use file url not real path. ex: folder/File1.html
var http = new XMLHttpRequest();
http.open('HEAD', url, false);
http.send();
if(http.status!=404){
    //file exist
}else{
    //file not exist
}

I have already tried this but it keeps on generating an error – Karan Parikh Oct 16 '16 at 07:31

I think the method XMLHttpRequest is deprecated – Karan Parikh Oct 16 '16 at 07:33
You have to do it from server. Because js don't support cross domain. you have to execute in server. – AHJeebon Oct 16 '16 at 07:35
I want to check it locally, not on server and I don't think there is a way of doing so – Karan Parikh Oct 16 '16 at 07:37
