<h2 class="first">Advanced Cookie Example</h2> |
|
|
102 |
<p>This example consists of three buttons, each of which performs one of the basic cookie functions: getting a value, |
|
|
103 |
setting a value, and removing a value. The first button, "Get Value", retrieves the value of a cookie |
|
|
104 |
and displays it in an alert:</p> |
|
|
105 |
<textarea name="code" class="JScript" cols="60" rows="1"> |
|
|
106 |
Y.Node.get("#yui-cookie-btn1").on("click", function(){ |
|
|
107 |
var value = Y.Cookie.get("example"); |
|
|
108 |
alert(value); |
|
|
109 |
Y.log("Cookie 'example' has a value of '" + value + "'"); |
|
|
110 |
}); |
|
|
111 |
</textarea> |
|
|
112 |
<p>The second button, "Set Random Value", creates a random value and sets the cookie's value equal to it:</p> |
|
|
113 |
<textarea name="code" class="JScript" cols="60" rows="1"> |
|
|
114 |
Y.Node.get("#yui-cookie-btn2").on("click", function(){ |
|
|
115 |
var newValue = "yui" + Math.round(Math.random() * Math.PI * 1000); |
|
|
116 |
Y.Cookie.set("example", newValue); |
|
|
117 |
Y.log("Set cookie 'example' to '" + newValue + "'"); |
|
|
118 |
}); |
|
|
119 |
</textarea> |
|
|
120 |
<p>After clicking this button, you can go back and click "Get Value" to see the new value that was assigned |
|
|
121 |
to the cookie (you can also check the logger output).</p> |
|
|
122 |
<p>The third button, "Remove Value", completely removes the cookie from the page:</p> |
|
|
123 |
<textarea name="code" class="JScript" cols="60" rows="1"> |
|
|
124 |
Y.Node.get("#yui-cookie-btn3").on("click", function(){ |
|
|
125 |
Y.Cookie.remove("example"); |
|
|
126 |
Y.log("Removed cookie 'example'."); |
|
|
127 |
}); |
|
|
128 |
</textarea> |
|
|
129 |
<p>When this button is clicked, it removes the cookie. If "Get Value" is clicked immediately afterwards, the |
|
|
130 |
value should be <code>null</code>.</p> </div> |
