Automatically Resizing a Canvas App

The following code examples show how to call the autogrow method to resize a canvas app. Use this method when your content will change size, but you’re not sure when.

In Mozilla® Firefox® and Microsoft® Internet Explorer®, the autogrow method might not resize the frame if the content size is reduced. In this case, you can use the resize method to specify the exact size that you want to change the frame to.

Note

1swfobject.registerObject("clippy.codeblock-0", "9");// Turn on auto grow with default settings.
2Sfdc.canvas(function() {
3    sr = JSON.parse('<%=signedRequestJson%>');
4    Sfdc.canvas.client.autogrow(sr.client);
5});

7// Turn on auto grow with polling interval of 100ms (milliseconds).
8Sfdc.canvas(function() {
9    sr = JSON.parse('<%=signedRequestJson%>');
10    Sfdc.canvas.client.autogrow(sr.client, true, 100);
