Hi there

How would I go about determining each individual text character in a textarea? ?

@Mr_JJun 19.2005 — Do you mean something like this?

<textarea id="t1">Hello World</textarea>

<script type="text/javascript">

<!--

var my_string = document.getElementById("t1").value

for(i=0;i<my_string.length;i++){

alert(my_string.charAt(i))

}

//-->

</script>

@JericoauthorJun 20.2005 — another question: here's my code:

if (my_string.charAt(i)==""){

document.write("&nbsp&nbsp&nbsp&nbsp")

I'm trying to ask if there's a blank space in the text area, and if there is I want to write 4 blank spaces - this code isn't working, but am I close???

@Mr_JJun 20.2005 — You are close, try this

[code=php]if(my_string.charAt(i)==" "){
document.write("&nbsp&nbsp&nbsp&nbsp")
}[/code]
Note the space between the quotes
