Behave.js is a lightweight library for adding IDE style behaviors to plain text areas, making it much more enjoyable to write code in.
var editor = new Behave({
textarea: document.getElementById('myTextarea')
});
var editor = new Behave({
textarea: null,
replaceTab: true,
softTabs: true,
tabSize: 4,
autoOpen: true,
overwrite: true,
autoStrip: true,
autoIndent: true,
fence: false
});
softTabs
is set to true, the number of spaces used is defined here. If set to false, the CSS property tab-size will be used to define hard tab sizes.
autoOpen
set to true
autoOpen
set to true
editor.destroy();
Hooks are fired at different times through Behave. To add your own hooks to extend the functionality of Behave, use the BehaveHooks
function.
BehaveHooks.add('keydown', function(data){
// Your Code
});
The add
function accepts two parameters, the hook name, and the function.
The hook you want to add an event for. May be a string or an array of hook names
The function you want to fire on the hook event
The following hook names are available for use:
Called before initializing Behave
Called after initializing Behave
Called before inserting the text triggered by the enter key
Called after inserting the text triggered by the enter key
Called before deleting the text triggered by the delete key
Called after deleting the text triggered by the delete key
Called before inserting the text triggered by the tab key
Called after inserting the text triggered by the tab key
Called before modifying the text triggered by the keyup event
Called after modifying the text triggered by the keydown event
Each hook excluding the init hooks accept a single parameter, an object with the following information:
{
caret: {
pos: 5
},
editor: {
element: textarea
levelsDeep: 1,
text: 'foo{}'
},

}
