Jquery loop through items separately

JavaScript
1

Hi,

I want to travel through a for loop of list elements with JQuery, to separately let every list element float downwards.

If I do this without a for loop, it works perfectly:

<script type="text/javascript">
$(document).ready(function() {
     
 $('#menu li').animate({ "opacity": "0", "marginTop": "-300px" },0);

 $('#thebutton').click(function(){ 
  var items = $('#menu > li');
     $(items[0]).delay().animate({ "opacity": "1", "marginTop": "2px" }, 400);
     $(items[1]).delay(200).animate({ "opacity": "1", "marginTop": "2px" }, 400);
     $(items[2]).delay(400).animate({ "opacity": "1", "marginTop": "2px" }, 400);
     $(items[3]).delay(600).animate({ "opacity": "1", "marginTop": "2px" }, 400);
     $(items[4]).delay(800).animate({ "opacity": "1", "marginTop": "2px" }, 400);
     $(items[5]).delay(1000).animate({ "opacity": "1", "marginTop": "2px" }, 400);
 $('#thebutton').animate({ "opacity": "0", "marginTop": "-300px" }, 500);
 });

$('#backbutton').click(function(){
     $('#menu > li').animate({ "opacity": "0", "marginTop": "-300px" }, 700);
     $('#thebutton').animate({ "opacity": "1", "marginTop": "5px" }, 500);
});

});
</script>

But if I do this with a for loop, all li elements go downwards directly… :s
Someone has experience with this? I guess there’s a better solution to reduce code with a for loop.

<script type="text/javascript">
$(document).ready(function() {

 $('#menu li').animate({ "opacity": "0", "marginTop": "-300px" },0);

 $('#thebutton').click(function(){ 
  var items = $('#menu > li');
  for (i=0;i<=items.length;i++){
     $(items[i]).delay(300).animate({ "opacity": "1", "marginTop": "2px" }, 1700);
  }
 $('#thebutton').animate({ "opacity": "0", "marginTop": "-300px" }, 500);
 });

$('#backbutton').click(function(){
     $('#menu > li').animate({ "opacity": "0", "marginTop": "-300px" }, 700);
     $('#thebutton').animate({ "opacity": "1", "marginTop": "5px" }, 500);
});

 
});
</script>

Here’s the html where the javascript needs to be added:

Found it, this was the solution:


  for (var i=0;i<items.length;i++) {
  $(items[i]).delay(i*200).animate({ "opacity": "1", "marginTop": "2px" }, 400);

You can make nice stuff with that. I made a demo page with downloadable code for a liquid menu in JQuery. http://bulevardi.be/?content=javascript&example=exjq1
