get()
The same as getAttribute() except:
- If the attribute is specified on the element then the returned value is cast to the same type as the value defined on the behavior.
- If the attribute is not specified on the element then the returned value is the value defined on the behavior.
Syntax
behavior.get(element, propertyName);
Example
var number = jsb.behavior.extend({
max: 100,
onchange: function(element) {
var max = this.get(element, "max");
if (element.value > max) {
alert("Please enter a number less than " + max);
}
}
});
The above example needs to be understood in the context of some HTML content:
<input type="text" value="50"> <input type="text" value="50" max="200">
For the first <input> element the value of
number.get(element, "max") is 100 (the default value).
For the second element the value is 200 (defined on the element).
Notes
HTML5 allows the creation of custom data attributes with the prefix "data-". It is suggested that you use this notation to store data associated with the element.
