When editing
Visualforce pages through the development mode footer or from Setup, an editor
is available with the following functionality:
- Syntax highlighting
- The editor automatically applies syntax highlighting for keywords
and all functions and operators.
- Search (
)
- Search enables you to search for text within the current page,
class, or trigger. To use search, enter a string in the Search textbox and click Find Next.
- To replace a found search string with another string, enter the
new string in the Replace textbox and click replace to replace just that instance, or Replace All to replace that instance and all other instances
of the search string that occur in the page, class, or trigger.
- To make the search operation case sensitive, select the Match Case option.
- To use a regular expression as your search string, select the Regular Expressions option. The regular expressions follow
JavaScript's regular expression rules. A search using regular expressions
can find strings that wrap over more than one line.
If you use the
replace operation with a string found by a regular expression, the
replace operation can also bind regular expression group variables
($1, $2, and so on) from the found search
string. For example, to replace an <h1> tag with an <h2> tag and
keep all the attributes on the original <h1> intact, search for <h1(\s+)(.*)> and replace it with <h2$1$2>.
- Go to line (
)
- This button allows you to highlight a specified line number. If
the line is not currently visible, the editor scrolls to that line.
- Undo (
) and Redo (
)
- Use undo to reverse an editing action and redo to recreate an
editing action that was undone.
- Font size
- Select a font size from the drop-down list to control the size
of the characters displayed in the editor.
- Line and column position
- The line and column position of the cursor is displayed in the
status bar at the bottom of the editor. This can be used with go to
line (
) to quickly navigate through the editor.
- Line and character count
- The total number of lines and characters is displayed in the status
bar at the bottom of the editor.
