Below is a snippet of code that allows for the reading of file content line by line.
document.getElementById('file').onchange = function() {
var file = this.files[0];
var reader = new FileReader();
reader.onload = function(progressEvent) {
var fileContentArray = this.result.split(/\r\n|\n/);
for (var line = 0; line < fileContentArray.length - 1; line++) {
console.log(line + " --> " + fileContentArray[line]);
}
};
reader.readAsText(file);
};
In JavaScript, delaying execution can be achieved using:
setTimeout(function() {
}, 1000)
The goal here is to display each line with a one-second delay between them.
However, attempts to integrate the delay before the for loop have been unsuccessful.
