How to read a .txt file and convert to string in javascript? [duplicate]
This question already has an answer here:
Upload File as String to JavaScript Variable
2 answers
I am trying to use javascript to read a .txt file, but I cannot seem to find any methods online. The purpose of the code is to scan a text file for a certain string. In my code the user purposely uploads the file and it is stored in a variable, but i cannot find a way to actually read the text in the file and convert into a string. Any help would be appreciated, thanks.
document.getElementById("answer").addEventListener(search);
document.getElementById("actualAns").addEventListener(search);
function myFunction() {
var targetAns = document.getElementById("answer").value; //the user inputs a .txt file
var actualAns = document.getElementById("actualAns").value; //the user enters the string they want to search
var n = actualAns.search(targetAns); // this part does not work, it should search the text file but it only searches the name
if(n > -1) {
document.getElementById("result").innerHTML = "Correct";
} else {
document.getElementById("result").innerHTML = "Incorrect";
}
}

You can read the file like this:
function readFile() {
jQuery.get("file.txt", function(textString)) {
//do what you want with the textString
});
}
and in the textString you will have the string of text present in your file.

While this might answer the authors question, it lacks some explaining words and/or links to documentation. Raw code snippets are not very helpful without some phrases around them. You may also find how to write a good answer very helpful. Please edit your answer - From Review
