<b>Combining Options</b><br>
|
|
|
115 |
Using the options argument, it is possible to combine different types of listeners:<br>
|
|
|
116 |
<br>
|
|
|
117 |
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
|
|
|
118 |
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
|
|
|
119 |
single: true,
|
|
|
120 |
delay: 100,
|
|
|
121 |
forumId: 4
|
|
|
122 |
});</code></pre>
|
|
|
123 |
<p>
|
|
|
124 |
<b>Attaching multiple handlers in 1 call</b><br>
|
|
|
125 |
The method also allows for a single argument to be passed which is a config object containing properties
|
|
|
126 |
which specify multiple handlers.
|
|
|
127 |
<p>
|
|
|
128 |
<pre><code>foo.on({
|
|
|
129 |
<em>'click'</em> : {
|
|
|
130 |
fn: <b>this</b>.onClick,
|
|
|
131 |
scope: <b>this</b>,
|
|
|
132 |
delay: 100
|
|
|
133 |
},
|
|
|
134 |
<em>'mouseover'</em> : {
|
|
|
135 |
fn: <b>this</b>.onMouseOver,
|
|
|
136 |
scope: <b>this</b>
|
|
|
137 |
},
|
|
|
138 |
<em>'mouseout'</em> : {
|
|
|
139 |

|
|
|
143 |
