Javascript and Jquery:

I currenlty working on the following:

image text in transcribed

I have figured out how to complete the second portion, but am struggling to make a Row Number appear after new added items. This is the code I have so far(I believe delegation has to be implemented with the second function within example.js but am not sure how to do this. I also did not include the second js file because it is too large. However, it can be found here: http://javascriptbook.com/code, pressing the download button, opening chapter 7, going to the js file, and opening jquery-1.11.0.js) :

  • fresh figs
  • pine nuts
  • honey
  • balsamic vinegar

JS: exmaple.js

$(function() {

// SETUP var $list, $newItemForm, $newItemButton; var item = ''; // item is an empty string $list = $('ul'); // Cache the unordered list $newItemForm = $('#newItemForm'); // Cache form to add new items $newItemButton = $('#newItemButton'); // Cache button to show form

$('li').hide().each(function(index) { // Hide list items $(this).delay(450 * index).fadeIn(1600); // Then fade them in });

// ITEM COUNTER function updateCount() { // Create function to update counter var items = $('li[class!=complete]').length; // Number of items in list $('#counter').text(items); // Added into counter circle } updateCount(); // Call the function

// SETUP FORM FOR NEW ITEMS $newItemButton.show(); // Show the button $newItemForm.hide(); // Hide the form $('#showForm').on('click', function() { // When click on add item button $newItemButton.hide(); // Hide the button $newItemForm.show(); // Show the form });

// ADDING A NEW LIST ITEM $newItemForm.on('submit', function(e) { // When a new item is submitted e.preventDefault(); // Prevent form being submitted var text = $('input:text').val(); // Get value of text input $list.append('

  • ' + text + '
  • '); // Add item to end of the list $('input:text').val(''); // Empty the text input updateCount(); // Update the count });

    // CLICK HANDLING - USES DELEGATION ON

      ELEMENT $list.on('click', 'li', function() { var $this = $(this); // Cache the element in a jQuery object var complete = $this.hasClass('complete'); // Is item complete

      if (complete === true) { // Check if item is complete $this.animate({ // If so, animate opacity + padding opacity: 0.0, paddingLeft: '+=180' }, 500, 'swing', function() { // Use callback when animation completes $this.remove(); // Then completely remove this item }); } else { // Otherwise indicate it is complete item = $this.text(); // Get the text from the list item $this.remove(); // Remove the list item $list // Add back to end of list as complete .append('

    • ' + item + '
    • ') .hide().fadeIn(300); // Hide it so it can be faded in updateCount(); // Update the counter } // End of else option }); // End of event handler

      });

      $(function() { var ids = ''; var $listItems = $('li');

      $listItems.on('mouseover click', function() { ids = this.id; $listItems.children('span').remove(); $(this).append(' ' + " Row Number: " + $(this).index() + ''); });

      $listItems.on('mouseout', function() { $(this).children('span').remove(); });

      });

      Requirements: When you hover your mouse over the rows, the row number would appear trailing (appear after) the text of that row. After the mouse leaves the row, the row number should disappear. The "NEW ITEM" button in the example let you insert new rows. After new rows are inserted, you need to make sure the effect you implemented above works for the newly added rows also A row can be deleted if clicked on. The row count needs to be updated after the deletion. Example screenshots: 1. 2.
