Can a text input box be automatically resized as text is entered? I've been looking online but haven't come across any solutions.
Can a text input box be automatically resized as text is entered? I've been looking online but haven't come across any solutions.
Here is a custom solution I created for you: http://jsfiddle.net/FNMSP/2/
function autoResizeField(e){
var element=e.target;
var top=element.scrollTop;
element.scrollTop=0
if(top>0){
element.style.height=(element.offsetHeight+top+top)+"px";
}
}
You can apply this function to the textarea like this,
<textarea onkeydown="autoResizeField(event)">Auto Resize!</textarea>
Alternatively, use the following code snippet to attach the function to all <textarea>:
var elements=document.getElementsByTagName("textarea");
for(i=0;i<element;i++){
elements[i].addEventListener("keydown",autoResizeField,false)
}
Go ahead and give it a try.
Here's a quirky but straightforward code example!
<script>
function grow(element)
{
element.size += 10;
}
</script>
<form>
<input onkeypress="grow(this)" size="10"/>
</form>
<SCRIPT LANGUAGE="JavaScript" type="text/javascript">
function adjust_textbox_size(max_length) {
if((document.form1.mybox.value == null ) ||
(document.form1.mybox.value == "" ))
document.form1.mybox.size = size;
if((document.form1.mybox.value.length >= size) &&
(document.form1.mybox.value.length <= max_length))
document.form1.mybox.size = document.form1.mybox.value.length + 1;
else
document.form1.mybox.size = size;
}
</script>
LastName: <input type="text" style="font-family: Terminal"
name="mybox" maxlength="30" size="10"
onFocus="setInterval('adjust_textbox_size(document.form1.mybox.maxLength)', 1)">
<SCRIPT LANGUAGE="JavaScript">
var size = document.form1.mybox.size;
</script>
