属性详情

$attributeOrder 公共 静态 属性

The preferred order of attributes in a tag. This mainly affects the order of the attributes that are rendered by renderTagAttributes().

public static array $dataAttributes = ['data''data-ng''ng']
$voidElements 公共 静态 属性

List of void elements (element name => 1)

参见 http://www.w3.org/TR/html-markup/syntax.html#void-element.

方法详情

a() 公共 静态 方法

Generates a hyperlink tag.

参见 yii\helpers\Url::to().

public static string a($text, $url null, $options = [])
$text string

Link body. It will NOT be HTML-encoded. Therefore you can pass in HTML code such as an image tag. If this is coming from end users, you should consider encode() it to prevent XSS attacks.

$url array|string|null

The URL for the hyperlink tag. This parameter will be processed by yii\helpers\Url::to() and will be used for the "href" attribute of the tag. If this parameter is null, the "href" attribute will not be generated.

If you want to use an absolute url you can call yii\helpers\Url::to() yourself, before passing the URL to this method, like this:

Html::a('link text', Url::to($url, true))
$options array

The tag options in terms of name-value pairs. These will be rendered as the attributes of the resulting tag. The values will be HTML-encoded using encode(). If a value is null, the corresponding attribute will not be rendered. See renderTagAttributes() for details on how attributes are being rendered.

$type string

The input type. This can be either radio or checkbox.

$model yii\base\Model

The model object

$attribute string

The attribute name or expression. See getAttributeName() for the format about attribute expression.

$model yii\base\Model

The model object

$attribute string

The attribute name or expression. See getAttributeName() for the format about attribute expression.

$options array

Options (name => config) for the checkbox list container tag. The following options are specially handled:

  • tag: string|false, the tag name of the container element. False to render checkbox without container. See also tag().
  • unselect: string, the value that should be submitted when none of the checkboxes is selected. You may set this option to be null to prevent default value submission. If this option is not set, an empty string will be submitted.
  • encode: boolean, whether to HTML-encode the checkbox labels. Defaults to true. This option is ignored if item option is set.
  • separator: string, the HTML code that separates items.
  • itemOptions: array, the options for generating the checkbox tag using checkbox().

    where $index is the zero-based index of the checkbox in the whole list; $label is the label for the checkbox; and $name, $value and $checked represent the name, value and the checked status of the checkbox input.

  • prompt: string, a prompt text to be displayed as the first option. Since version 2.0.11 you can use an array to override the value and to set other tag attributes:

    ['text' => 'Please select', 'options' => ['value' => 'none', 'class' => 'prompt', 'label' => 'Select']],
    
  • options: array, the attributes for the select option tags. The array keys must be valid option values, and the array values are the extra attributes for the corresponding option tags. For example,

    [
        'value1' => ['disabled' => true],
        'value2' => ['label' => 'value 2'],
    ];
    
  • groups: array, the attributes for the optgroup tags. The structure of this is similar to that of 'options', except that the array keys represent the optgroup labels specified in $items.

$options array

The tag options in terms of name-value pairs. The following options are specially handled:

  • uncheck: string, the value associated with the uncheck state of the checkbox. When this attribute is present, a hidden input will be generated so that if the checkbox is not checked and is submitted, the value of this attribute will still be submitted to the server via the hidden input.
  • label: string, a label displayed next to the checkbox. It will NOT be HTML-encoded. Therefore you can pass in HTML code such as an image tag. If this is is coming from end users, you should encode() it to prevent XSS attacks. When this option is specified, the checkbox will be enclosed by a label tag.
  • labelOptions: array, the HTML attributes for the label tag. Do not set this option unless you set the "label" option.

The rest of the options will be rendered as the attributes of the resulting checkbox tag. The values will be HTML-encoded using encode(). If a value is null, the corresponding attribute will not be rendered. See renderTagAttributes() for details on how attributes are being rendered.
