Jquery

read input char and do something if 13

as part of initialization

       bindEvents: function () {
           var list = this.$todoList;
           this.$newTodo.on('keyup', this.create);

the 'keyup produces a key code. This code returns doing nothing until the keyup is 13(return) <source lang="javascript">

       create: function (e) {
           var $input = $(this);
           var val = $.trim($input.val());

           if (e.which !== App.ENTER_KEY || !val) {
               console.log(e.which);
               return;
           }

           App.todos.push({
               id: Utils.uuid(),
               title: val,
               completed: false
           });

           $input.val();
           App.render();
       },

</source>

$.post $.get

<syntaxhighlight lang="javascript">

   $.post("../services/hold.php", {data: holdStr}).done(function(data){
       //alert("Data Loaded: " + data);
   });

</syntaxhighlight>

autocomlete

You can send more info to the autocomplete script:

In this case &course:33duck gets appended to the get string going to ../tm/smcompl.php

from: /assess/combine/createCquiz.html

<syntaxhighlight lang="javascript">

   $("#quesfrom").autocomplete({
       source: function(request, response) {
           $.getJSON("../tm/smcompl.php", {
               term: extractLast(request.term),
               course: document.getElementById("numques").value + 'duck'
           }, response);
       //$.getJSON("../tm/smcompl.php", {term: extractLast(request.term)}, response);
       },

</syntaxhighlight>
