如何在textarea中添加更多文本
问题描述：
I want to create console.
I have textarea:
<textarea style="width: 100%; height: 300px; resize: none;" id="console_output" readonly></textarea>
And using this code to insert more text:
else echo "<script>$('#console_output').append('Some text.
');</script>";
But nothing happened, textarea is empty.
答
Your code should work as you can check JsFiddle
$('#console_output').append('Some text.
');
Will not work if
- you are not into your else statement
- textarea is not there yet if dynamically created
- you have no jquery included
You can try with pure js:
echo '<script>document.getElementById("console_output").value += "Some text.
";</script>';
