DOM Property Viewer user interface¶
The different properties of the DOM are displayed as an expandable tree. The left-hand side shows the property’s name, and the right-hand side shows its value. Up to three properties of an object and items of an array are displayed. If a property has more elements than this, you’ll see a “more…” annotation, and will need to click the property to see all elements. A lock icon indicates that a property is not writable.
Refreshing the display¶
If the DOM changes you can hit the Refresh button to update the display:
There is a search box within the toolbar:
This filters the list to show only items which match the search term. Items match the search term if their name contains the search term. Matching is case-sensitive.
