Character counter for HTML input and textarea fields. The count is updated on the keyup event for the element the plugin is attached to. Requires jQuery 1.6 or higher.
Basic usage requires the input/textarea field to have a "maxlength" attribute set. A "span" element with class "charcount" will be added after the input field and will display the current number of characters and the maximum like so: "count / max". Instantiate plugin like so:
$(element).charcount();
An options object can be passed in during instatiation to customise. See the next section for details.
The properties can be set during instatiation of the plugin. The template, the element in the DOM to add the count to, and the maximum count.
| Property | Type | Description |
|---|---|---|
| tmpl | string | Template fields are {count} - the current number of characters in the element, {max} - the maximum, {remaining} - maximum minus current number of characters. The default template is "{count}/{max}". |
| max | integer | The maximum number of characters allowed in this element. Will override the "maxlength" attribute. |
| appendTo | jQuery object | Element to add the count template to. |
Example with options:
$('textarea').characount({
max: 200,
appendTo: $(otherElement),
tmpl: "{remaining}"
});
