Error Handling - Display Array If Not Empty Into DIV
Sep 17, 2009I'm not an expert with javascript nor am I too familiar with the syntax. What I'm trying to do is store all errors into an array like so:
Code JavaScript:
var errors = new Array();
var example = '';
if (example == '') {
errors[] = 'This example field is empty';
}
What I'm trying to do at the end is display the array if its not empty into a DIV called errors (or something). I know how to do this in PHP but I'm trying to do first validation layer through javascript. So something like this:
Code JavaScript:
<div class="errors">
if (errors != '') {//If the array is not empty
for (keyvar in errors) {
document.write(array[keyvar]);//Display Errors
}
}
</div>
Take Data From An Array And Apply Each Array Item To An Element
Mar 26, 2010I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.

Endless Loop If Two Item To Sort Are Equal
Jun 12, 2010I figured out the one question but I am thinking the code below would get into an endless loop if two items to sort were equal because it never returns a 0 to alert the javascript sort function that the two items are equal... Is this correct?
The code ...
$(document).ready(function() {
$('#ascending').click(function() {
SORTER.sort('.sortable');
});
$('#descending').click(function() {
SORTER.sort('.sortable', 'desc');
});
});
var SORTER = {};
SORTER.sort = function(which, dir) {
SORTER.dir = (dir == "desc") ? -1 : 1;
$(which).each(function() {
// Find the list items and sort them
var sorted = $(this).find("> li").sort(function(a, b) {
return $(a).text().toLowerCase() > $(b).text().toLowerCase() ? SORTER.dir : -SORTER.dir;
});
$(this).append(sorted);
});
};

JQuery :: Reference Unordered List Item As An Array?
Mar 9, 2011I have an unordered list that I am using as a menu. This list contains sub lists.
I found out how to get the index of the primary unordered list item that is being hovered but I am not getting the syntax correct to reference the individual items of this listto get the HTML, the position, height and lengthof this item.
$(" #nav li").hover(function(){
// Locate the index of the singular list item that is being hovered
var index = $(this).parent().children('li').index(this);
// This is incorrect
var $itemObject = $(this).parent().children('li')[index];
JQuery :: Find Position Of A Clicked Item In An Array?
Jan 12, 2010Hi, i'm creating my own image gallery using jQuery, and there is a set of thumbnails at the bottom. The thumbnails have been put into an array, using jQuery, but what i am trying to do is to return the position of any clicked thumbnail in that array. i.e. when the 3rd thumbnail in the list is clicked, return 3, when the 5th thumbnail is clicked return 5 etc....
This in turn will dictate which item in another array (the main images array) will be displayed.
