Load Text From Local .txt File Into Html Textarea Using Javascript
I have a
Solution 1:
You can use the File and FileReader objects to read local files.
You can use an input element with type="file" to allow the user to select a file.
<input id="myFile"type="file"/>
<textarea id="myTextArea" rows="4" columns="20"></textArea>
After the user has selected a file, you can get the File object from the input element. For example...
var file = document.getElementById("myFile").files[0];
You can then use a FileReader object to read the file into the text area. For example...
var reader = newFileReader();
reader.onload = function (e) {
var textArea = document.getElementById("myTextArea");
textArea.value = e.target.result;
};
reader.readAsText(file);
Solution 2:
I found a old topic about this: How do I load the contents of a text file into a javascript variable?
Have you read the last answer already? This works with a div instead of a textbox, but you could adapt the code a bit.
In the last piece of the last commenters post you could change this line:
document.getElementById("id01").innerHTML = out;
to:
document.getElementById("textbox01").innerHTML = out;
And in your HTML:
<textareaname="textbox01">Enter text here...</textarea>
Result:
functionloadFile() {
var xmlhttp = newXMLHttpRequest();
var url = "file.txt";
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
var myArr = JSON.parse(xmlhttp.responseText);
myFunction(myArr);
console.log("xmlhttp Request Asepted");
}
}
xmlhttp.open("GET", url, true);
xmlhttp.send();
functionmyFunction(arr) {
var out = "";
var i;
var row = 0;
for(i = 0; i < arr.length; i++) {
// console.log( arr[1].data); change data to what every you have in your file// out += arr[i].data + '<br>' + arr[i].data2 ;document.getElementById("textbox01").innerHTML = out;
}
}
}
