Get the first word from sentence field

Hi ,

I am new in javascript. I need a code that get only the first word from the sentence field and make the word in lowercase onblur .

Hi fayezsaad,

Use indexOf() to search space and use substring() to get the first word
Use toLowerCase() to change to lowercase
append the remaining string to this changed value and assign it back to the control

Cheers!

Here is an example though:

<input type=text onblur="changeCase(this)"/>

<script>
function changeCase(obj)
{
var str=obj.value;
var firstWord=str;
if (str.indexOf(" ")!=-1) firstWord=str.substring(0,str.indexOf(" "));
firstWord=firstWord.toLowerCase();
var newValue="";
if (str.indexOf(" ")!=-1) newValue=firstWord+str.substr(str.indexOf(" "));
else newValue=firstWord;
obj.value=newValue;
}
</script>

Or you can do it with Regexp if the mood takes you ;-)

<html>
<body>
<script type="text/javascript">
function doit( aTextField )
{
var aTxt = aTextField.value ;

var words = aTxt.match( /(\S+).*/ ) ;
if( words && words.length > 1 )
{
aTxt = aTxt.replace( /\S+/, words[ 1 ].toLowerCase() ) ;
aTextField.value = aTxt ;
}
}
</script>
<textarea onblur="doit( this )"></textarea>
</body>
</html>
