Suppose i have textbox :-
<input type="text" name="content" id="content"/>
And i am trying append text to this input box in the following manner:-
document.getElementById("content").value+= "A";
The output is something like:-
AAAA....
Each time, the text is getting appended in the same line, how can make the text to append each time to the new line? Like that of below.
A
A
A
.
.
Instead of an input type text, you can use a text area and then style it to look like a text box.
<textarea name="textarea_content" id="tx_content"></textarea>
document.getElementById("tx_content").value+= "A\n";
document.getElementById("tx_content").value+= "A\n";

The input textbox will support one single line. not multiple lines. that is it's behaviour. That's why your text is shown in a single line.
If you need multiple lines, then you need to use <textarea></textarea>
element
input
is used for a single line. Try using textarea
.
Refer code below:
<textarea type="text" name="content" id="content">
</textarea>
and js will be like this:
document.getElementById("content").value+= "A\n";
I have made you an example that appends a new "A" char every 5 seconds. I use textarea instead of the input tag.
setInterval(appendNewChar, 5000) function appendNewChar() { document.getElementById("myTextArea").value += "A\\n"; }
<textarea id="myTextArea"></textarea>
As @GuyFromChennai said, you have to use tag instead of , also, writing '\\n' will make the line break, I tried this:
<textarea name="content" id="content"></textarea>
for (let i=0; i<3; i++){
document.getElementById("content").value+= "A\n"";
}
