    JS Array with timeout not working correctly

    I want this array to write hello wait 1 second and write world wait a second and write !. but it doesn't do that what am i missing.

    Code:
    <script language="javascript">
    var myArr = new Array();
    myArr[0] = "Hello";
    myArr[1] = "World";
    myArr[2] = "!";
    
    function wait(){
    	timeout = setTimeout(function(){test()}, 1000);//waits 1 second  10000 = 10 seconds
    
    
    }
    function test(){
    window.clearTimeout(timeout);
    for (i=0; i < myArr.length; i++){
    console.log(myArr);
    alert(myArr[i]);
    wait();
    }
    }
    
    test();
    </script>

    Every time you call the function test, your variable is RE initialized to zero. You either need to use a global variable outside the function, or don't use a loop at all, and use set interval instead of set timeout.

    thanks Jpnyc, I got it working with alert, however, when i change it to write to a particular div it will write once and stop unless i put the alert at the beginning of the loop.
    Code:
    function feat() {
    window.clearTimeout(timeout);
    	for (var i=0; i < bNameArray.length; i++)
    		{
    		alert(bNameArray[i]);
    		document.getElementById("fName").innerHTML= bNameArray[i] + "<br>";
    		if(logoArray[i] != '') {
    		document.getElementById("fLogo").innerHTML= "<img src='http://www.westbywi.com/images/featuredBus/" + logoArray[i] +  "' width='180px'>";
    		} else {
    		document.getElementById("fLogo").innerHTML= "";
    		}	
    		document.getElementById("fDesc").innerHTML=descriptionArray[i] + "<br>";
    		if(cNameArray[i] != '') {
    		document.getElementById("fCname").innerHTML=cNameArray[i];
    		} else {
    		document.getElementById("fCname").innerHTML="";
    		}
    		document.getElementById("fAddress").innerHTML=addressArray[i] + "<br>" + cityArray[i] + ", " + stateArray[i] +" "+ zipArray[i];
    		document.getElementById("fPhone").innerHTML="Phone: " + phoneArray[i];
    		if(emailArray[i] != '') {
    		document.getElementById("fEmail").innerHTML= "<a href='mailto:" + emailArray[i] + "'>Email Us</a>"; 
    		} else {
    		document.getElementById("fEmail").innerHTML= "";
    		} 
    		if(urlArray[i] != '') {
    		document.getElementById("fUrl").innerHTML= "<a href='" + urlArray[i] + "' target='_blank'>" + urlArray[i] + "</a>" ;
    		} else {
    		document.getElementById("fUrl").innerHTML= "" ;
    		}
    	}	
    }
    
    feat();
    Here is the link so you can see the entire page. http://www.westbywi.com/test3.php
    why would putting the alert let it cycle through correctly and show only once without it?
    I know how to move the pointer back to the beginning of an array in php but not JS. if i change the
    Code:
    for (var i=0; i < bNameArray.length; i++)
    to
    Code:
    for (var i=0; i <( bNameArray.length*3); i++)
    it gives me an undefined after it reaches the end of the array. how do i reset the array to the 0 position?

    Thanks again.

    html file

    HTML Code:
    <!DOCTYPE html>
    <html lang="en">
    <head>
    <meta charset="utf-8">
    <title>hello world !</title>
    <script src="hw.js"></script>
    </head>
    <body>
    <p id="here"></p>
    </body>
    </html>
    save file as hw.js or change html to suit

    Code:
    var hwArr = (function () {
    	var myArr, index, here;
    	function test() {
    	    var str = '',
    		    i;
    	    if (index < 4) {
    		    for (i = 0; i < index; i += 1) {
    			    str += myArr[i] + ' ';
    			}
    			index += 1;
    			here.innerHTML = str;
    		    setTimeout(function () {test(); }, 1000);
    		}
    	}
    	function initAll() {
    	    myArr = ['Hello', 'World', '!'];
    		index = 1;
    		here = document.getElementById('here');
    		test();
    	}
    	return ({
    	    start: initAll
    	});
    }());
    window.onload = function () {
    	hwArr.start();
    };
