Spell Checker

[jmallen]

Hello, I am working on a project. I am mostly new with javascript. I have taken a java script class before(was not very helpful).

I am now trying to learn more on my own. I have this spell check program I have been creating.

I am unsure how to loop through my array(wordlist array) and then compare my array to the variable(wordVar), which is entered by the user.

The idea is that if the variable exists in the array then the program will display Correct spelling. If it is wrong I would like to show the correct spelling of the word. However, right now I am more interested in looping through my array and comparing the variable

Here is my javascript and my form:

	<script type="text/javascript">
	<!-- 
		
		//wordlist array declared and populated
		var wordlist = new Array(6);
			wordlist[0] = "dog";
			wordlist[1] = "potato";
			wordlist[2] = "napkin";
			wordlist[3] = "knife";
			wordlist[4] = "pumpkin";
			wordlist[5] = "probably";
			wordlist[6] = "wednesday";
			document.write("Result of array is - "+wordlist[0]);

			
			function readText (form) {
			wordVar =form.inputbox.value;
			alert ("You Entered: " + wordVar + ". Did you mean " + wordlist[0] + "?" );
			//alert(wordlist);
			//next loop through wordlist array and compare words somehow. switch input to all lower
}
-->
	</script>

The Form

<form name="myForm">
		<P>
		<input type="text" name="inputbox" value="">
		<input type="button" name="button1" Value="Read" onClick="readText(this.form)">
		</p>
		</form>

Something like this.

function readText (form) {
var found = false;
wordVar = form.inputbox.value.toLowerCase();
for (var i=0; i<wordlist.length; i++) {
if (wordlist[i] == wordVar) {
alert ("The word " + wordVar + " was found in the list");
found = true;
}
}
if (!found) {
alert ("The word" + wordVar + " was not found in the list");
}

But you will not be able to display the correct spelling of a mis-spelled word. How will you know whether hog is a mis-spelling of dog or of hot? The number of possible mis-spellings of a given word is huge or almost infinite.

A more modern and better way to populate your array is

var wordlist = ["dog", "potato", "napkin", "knife", "pumpkin", "probably", "wednesday"];

Be aware that the <!-- and //--> comment (hiding) tags have not been necessary since IE3 (i.e. since September 1997). If you see these in some published script it is a warning that you are looking at ancient and perhaps unreliable code.
