apex:commandLink

A link that executes an action defined by a controller, and then either refreshes the current page, or navigates to a different page based on the PageReference variable that is returned by the action. An <apex:commandLink> component must always be a child of an <apex:form> component.

To add request parameters to an <apex:commandLink>, use nested <apex:param> components.

See also: <apex:commandButton>, <apex:outputLink>.

This component supports HTML pass-through attributes using the "html-" prefix. Pass-through attributes are attached to the generated <a> tag.

Example

<apex:commandLink action="{!save}" value="Save" id="theCommandLink"/>

The example above renders the following HTML:

<a id="thePage:theForm:theCommandLink" href="#" onclick="generatedJs()">Save</a>

Attributes

Attribute Name Attribute Type Description Required? API Version Access
accesskey String The keyboard access key that puts the command link in focus. When the command link is in focus, pressing the Enter key is equivalent to clicking the link. 10.0 global
action ApexPages.Action The action method invoked by the AJAX request to the server. Use merge-field syntax to reference the method. For example, action="{!save}" references the save() method in the controller. If an action isn't specified, the page simply refreshes. Note that command links associated with the save, edit, or delete actions in a standard controller are rendered only if the user has the appropriate permissions. Likewise, command links associated with the edit and delete actions are rendered only if a record is associated with the page. 10.0 global
charset String The character set used to encode the specified URL. If not specified, this value defaults to "ISO-8859-1". 10.0 global
coords String The position and shape of the hot spot on the screen used for the command link (for use in client-side image maps). The number and order of comma-separated values depends on the shape being defined. For example, to define a rectangle, use coords="left-x, top-y, right-x, bottom-y". To define a circle, use coords="center-x, center-y, radius". To define a polygon, use coords="x1, y1, x2, y2, ..., xN, yN", where x1 = nN and y1 = yN. Coordinates can be expressed in pixels or percentages, and represent the distance from the top-left corner of the image that is mapped. See also the shape attribute. 10.0 global
