Ace editor gets value in one line

Question

I am trying to get the value in one line in the Ace editor.

According to Ace Editor documentation:

• gotoLine() to go to one line
• getLine() to get one line
• getLines() to get multiple rows

Here is what I tried:

 var html = ace.edit("html"); html.getSession().setMode("ace/mode/html"); html.setTheme("ace/theme/eclipse"); html.setPrintMarginColumn(false); html.resize(); var line4 = html.gotoLine(4); var getfour = html.getLine(4); var getfoureight = html.getLines(4,8); 

gotoLine() works. getLine() and getLines() do not work.

What am I doing wrong?

Answer 1

getLine and getLines are session functions, so they should be called as

 var editor = ace.edit("html"); editor.setValue("line0 \n line1 \n line2 \n line3") editor.session.getLine(2) // returns " line2 " editor.session.getLines(1, 2) // returns [" line1 ", " line2 "]
