阅读更多关于 Dynamically add and remove the div on scroll?

问题 I tried to add and remove div tags while scrolling like the Dojo grid works. I only want to display 7 div tags. While scrolling left inside the container, when the first div tag (on the left side) was hidden from the webpage, then that hidden div is removed from the container and a new one is attached onto the right side. The same process should be applied while scrolling to the right. It's similar to this example. But in stead of scrolling the <tr> tag, I want to scroll through <div> 's.

Dojo: Get ID of inlineEditBox on OnChange

阅读更多关于 Dojo: Get ID of inlineEditBox on OnChange

I'm using dojo and dijit and have an inlineEditBox widget. I'm trying to capture the onchange event and send a key/value post to a php page (to set into a database).

Since InlineEditBox is a widget it's best not to monitor DOM level events. Instead, why not connect to InlineEditBox.onChange? For example: <span dojoType="dijit.InlineEditBox" ...> <script type="dojo/connect" event="onChange" args="value">
