Using ACT Controls and the Ajax Minifier

20

The Ajax Minifier Tool

Shrink JavaScript or CSS files

Minifying a Script:

ajaxmin test.js -o test.min.js

Minifying a CSS file:

ajaxmin test.css -o test.min.css

21

So Now You’ve Got Some Data…var users = [ { firstName: “…", lastName: “…", blogAddress: “…", laptops: [“…", “…"], }, { firstName: “…", lastName: “…", blogAddress: “…", laptops: [“…", “…"], }];<ul id="usersList"></ul>

var usersListUL = document.getElementById('usersList');

for (var i = 0; i < users.length; i++) {    var user = users[i];    var newLI = "<li><a href=\"" + user.blogAddress + "\">" + user.firstName +

" " + user.lastName + "</a></li>";     usersListUL.innerHTML += newLI;}

22

Part 2 – More Complex Examplevar usersListUL = document.getElementById('usersList');

for (var i = 0; i < users.length; i++) {    var user = users[i];    var newLI = "<li><a href=\"" + user.blogAddress + "\">" + user.firstName + " " + user.lastName + "</a>";

    if (user.laptops != null && user.laptops.length > 0) {        newLI += "<br/>";        newLI += "<b>Laptops:</b> ";

        var counter = 0;        for (var j = 0; j < user.laptops.length; j++) {            var laptop = user.laptops[j];

            newLI += laptop;

            if (counter < user.laptops.length - 1) {                newLI += ", ";            }                            counter += 1;        }

    }

    newLI += "</li>";    usersListUL.innerHTML += newLI;}

<script id="MyTemplate" type="text/x-jquery-tmpl"> <li><a href="${blogAddress}">${firstName} {{= lastName}}</a></li></script>

jQuery Template Syntax

26

Applying a Template

<script id="MyTemplate" type="text/x-jquery-tmpl"> <li><a href="${blogAddress}">${firstName} {{= lastName}}</a></li></script>

<ul id="usersList"></ul>

<script>    $('#usersList').append("#MyTemplate", users);</script>

27

Adding Conditional Logic{{if product == null }} <tr> <td>No product selected</td> </tr>{{else}} <tr> <td> ${product.Name}: ${product.NumberOrdered} ordered at R${product.Price} per item </td> </tr> {{/if}}

28

Working with Loops{{if MainItems == null }} <tr> <td>No items selected</td> </tr>{{else}} {{each MainItems}} <tr> <td> ${this.Name}: ${this.NumberOrdered} ordered at R${this.Price} per item </td> </tr> {{/each}}{{/if}}

So Now You’ve Changed Some Data…<input id="nameTextbox" onchange="nameTextbox_Changed(this)" /> <br/><input id="ageTextbox" onchange="ageTextbox_Changed(this)" /> <br/>

<input type="button" id="btnSave" value="save" onclick="btnSave_Click(this)" />

31

Part 2 – linking one way<script>

    var person = { firstName: "", age: 0, canVote: false };

    function nameTextbox_Changed(sender) {        person.firstName = sender.value;    }

    function ageTextbox_Changed(sender) {        var adjustedAge = Math.round(sender.value);        person.age = adjustedAge;        person.canVote = adjustedAge >= 18;    }

    function btnSave_Click(sender) {        alert(person.firstName + " (" + person.age + ") can vote: " +

person.canVote);    }

</script>

32

Part 3 – Linking back    function btnSetInCode_Click(sender) {        person.firstName = "Hilton";        person.age = 120;        document.getElementById("nameTextbox").value = person.firstName;        document.getElementById("ageTextbox").value = person.age;    }

Using jQuery Data Linking

34

Data Linking

Name: <input id="firstName" /> <br/>Age: <input id="age" /> <br/>

<input type="button" id="btnSave" value="save" /> <br/>

<script>    var person = { };

    $().ready(function () {

        $("form").link(person);

        $("#btnSave").click(function () {            alert(person.firstName + " can vote:" + person.canVote);        });

    });</script>

35

person.firstName = "Hilton"; person.age = 120;

Data Linking

Must change data with jQuery:

$(person).data("firstName", "Hilton");$(person).data("age", 120);
