源码	framework/zii/widgets/grid/CGridView.php

CGridView displays a list of data items in terms of a table.

Each row of the table represents the data of a single data item, and a column usually represents an attribute of the item (some columns may correspond to complex expression of attributes or static text).

CGridView supports both sorting and pagination of the data items. The sorting and pagination can be done in AJAX mode or normal page request. A benefit of using CGridView is that when the user browser disables JavaScript, the sorting and pagination automatically degenerate to normal page requests and are still functioning as expected.

CGridView should be used together with a data provider, preferrably a CActiveDataProvider.

The minimal code needed to use CGridView is as follows:

$dataProvider=new CActiveDataProvider('Post');
$this->widget('zii.widgets.grid.CGridView', array(  'dataProvider'=>$dataProvider,
));

The above code first creates a data provider for the Post ActiveRecord class. It then uses CGridView to display every attribute in every Post instance. The displayed table is equiped with sorting and pagination functionality.

In order to selectively display attributes with different formats, we may configure the CGridView::columns property. For example, we may specify only the title and create_time attributes to be displayed, and the create_time should be properly formatted to show as a time. We may also display the attributes of the related objects using the dot-syntax as shown below:

$this->widget('zii.widgets.grid.CGridView', array(  'dataProvider'=>$dataProvider,  'columns'=>array(      'title',          // display the 'title' attribute      'category.name',  // display the 'name' attribute of the 'category' relation      'content:html',   // display the 'content' attribute as purified HTML      array(            // display 'create_time' using an expression          'name'=>'create_time',          'value'=>'date("M j, Y", $data->create_time)',      ),      array(            // display 'author.username' using an expression          'name'=>'authorName',          'value'=>'$data->author->username',      ),      array(            // display a column with "view", "update" and "delete" buttons          'class'=>'CButtonColumn',      ),  ),
));

Please refer to columns for more details about how to configure this property.

属性详细

afterAjaxUpdate 属性 public string $afterAjaxUpdate;

a javascript function that will be invoked after a successful AJAX response is received. The function signature is function(id, data) where 'id' refers to the ID of the grid view, 'data' the received ajax response data.

ajaxUpdate 属性 public mixed $ajaxUpdate;

the ID of the container whose content may be updated with an AJAX response. Defaults to null, meaning the container for this grid view instance. If it is set false, it means sorting and pagination will be performed in normal page requests instead of AJAX requests. If the sorting and pagination should trigger the update of multiple containers' content in AJAX fashion, these container IDs may be listed here (separated with comma).

ajaxUpdateError 属性 public string $ajaxUpdateError;

a javascript function that will be invoked if an AJAX update error occurs.

The function signature is function(xhr, textStatus, errorThrown, errorMessage)

• xhr is the XMLHttpRequest object.
• textStatus is a string describing the type of error that occurred. Possible values (besides null) are "timeout", "error", "notmodified" and "parsererror"
• errorThrown is an optional exception object, if one occurred.
• errorMessage is the CGridView default error message derived from xhr and errorThrown. Usefull if you just want to display this error differently. CGridView by default displays this error with an javascript.alert()

Note: This handler is not called for JSONP requests, because they do not use an XMLHttpRequest.

Example (add in a call to CGridView):

 ...
 'ajaxUpdateError'=>'function(xhr,ts,et,err){ $("#myerrordiv").text(err); }',
 ...

ajaxUrl 属性 （可用自 v1.1.8） public mixed $ajaxUrl;

the URL for the AJAX requests should be sent to. CHtml::normalizeUrl() will be called on this property. If not set, the current page URL will be used for AJAX requests.

ajaxVar 属性 public string $ajaxVar;

the name of the GET variable that indicates the request is an AJAX request triggered by this widget. Defaults to 'ajax'. This is effective only when ajaxUpdate is not false.

baseScriptUrl 属性 public string $baseScriptUrl;

the base script URL for all grid view resources (eg javascript, CSS file, images). Defaults to null, meaning using the integrated grid view resources (which are published as assets).

beforeAjaxUpdate 属性 public string $beforeAjaxUpdate;

a javascript function that will be invoked before an AJAX update occurs. The function signature is function(id,options) where 'id' refers to the ID of the grid view, 'options' the AJAX request options (see jQuery.ajax api manual).

blankDisplay 属性 （可用自 v1.1.7） public string $blankDisplay;

the text to be displayed in an empty grid cell. This property will NOT be HTML-encoded when rendering. Defaults to an HTML blank. This differs from nullDisplay in that nullDisplay is only used by CDataColumn to render null data values.

columns 属性 public array $columns;

grid column configuration. Each array element represents the configuration for one particular grid column which can be either a string or an array.

When a column is specified as a string, it should be in the format of "name:type:header", where "type" and "header" are optional. A CDataColumn instance will be created in this case, whose CDataColumn::name, CDataColumn::type and CDataColumn::header properties will be initialized accordingly.

When a column is specified as an array, it will be used to create a grid column instance, where the 'class' element specifies the column class name (defaults to CDataColumn if absent). Currently, these official column classes are provided: CDataColumn, CLinkColumn, CButtonColumn and CCheckBoxColumn.

cssFile 属性 public string $cssFile;

the URL of the CSS file used by this grid view. Defaults to null, meaning using the integrated CSS file. If this is set false, you are responsible to explicitly include the necessary CSS file in your page.

filter 属性 （可用自 v1.1.1） public CModel $filter;

the model instance that keeps the user-entered filter data. When this property is set, the grid view will enable column-based filtering. Each data column by default will display a text field at the top that users can fill in to filter the data. Note that in order to show an input field for filtering, a column must have its CDataColumn::name property set or have CDataColumn::filter as the HTML code for the input field. When this property is not set (null) the filtering is disabled.

filterCssClass 属性 （可用自 v1.1.1） public string $filterCssClass;

the CSS class name for the table row element containing all filter input fields. Defaults to 'filters'.

参见

• filter

filterPosition 属性 （可用自 v1.1.1） public string $filterPosition;

whether the filters should be displayed in the grid view. Valid values include:

• header: the filters will be displayed on top of each column's header cell.
• body: the filters will be displayed right below each column's header cell.
• footer: the filters will be displayed below each column's footer cell.

参见

• filter

formatter 属性 public CFormatter getFormatter()
public void setFormatter(CFormatter $value)

the formatter instance. Defaults to the 'format' application component.

hasFooter 属性 只读 public boolean getHasFooter()

whether the table should render a footer. This is true if any of the columns has a true CGridColumn::hasFooter value.

hideHeader 属性 （可用自 v1.1.1） public boolean $hideHeader;

whether to hide the header cells of the grid. When this is true, header cells will not be rendered, which means the grid cannot be sorted anymore since the sort links are located in the header. Defaults to false.

loadingCssClass 属性 （可用自 v1.1.1） public string $loadingCssClass;

the CSS class name that will be assigned to the widget container element when the widget is updating its content via AJAX. Defaults to 'grid-view-loading'.

nullDisplay 属性 public string $nullDisplay;

the text to be displayed in a data cell when a data value is null. This property will NOT be HTML-encoded when rendering. Defaults to an HTML blank.

rowCssClass 属性 public array $rowCssClass;

the CSS class names for the table body rows. If multiple CSS class names are given, they will be assigned to the rows sequentially and repeatedly. This property is ignored if rowCssClassExpression is set. Defaults to array('odd', 'even').

参见

• rowCssClassExpression

rowCssClassExpression 属性 public string $rowCssClassExpression;

a PHP expression that is evaluated for every table body row and whose result is used as the CSS class name for the row. In this expression, the variable $row stands for the row number (zero-based), $data is the data model associated with the row, and $this is the grid object.

参见

• rowCssClass

selectableRows 属性 public integer $selectableRows;

the number of table body rows that can be selected. If 0, it means rows cannot be selected. If 1, only one row can be selected. If 2 or any other number, it means multiple rows can be selected. A selected row will have a CSS class named 'selected'. You may also call the JavaScript function $.fn.yiiGridView.getSelection(containerID) to retrieve the key values of the selected rows.

selectionChanged 属性 public string $selectionChanged;

a javascript function that will be invoked after the row selection is changed. The function signature is function(id) where 'id' refers to the ID of the grid view. In this function, you may use $.fn.yiiGridView.getSelection(id) to get the key values of the currently selected rows.

参见

• selectableRows

showTableOnEmpty 属性 public boolean $showTableOnEmpty;

whether to display the table even when there is no data. Defaults to true. The emptyText will be displayed to indicate there is no data.

updateSelector 属性 （可用自 v1.1.7） public string $updateSelector;

the jQuery selector of the HTML elements that may trigger AJAX updates when they are clicked. If not set, the pagination links and the sorting links will trigger AJAX updates.
