This question is old, but for anybody looking for a solution, I built a simple directive to handle this, for vertical and horizontal resizers.
Take a look at the Plunker
angular.module('mc.resizer', []).directive('resizer', function($document) {
return function($scope, $element, $attrs) {
$element.on('mousedown', function(event) {
event.preventDefault();
$document.on('mousemove', mousemove);
$document.on('mouseup', mouseup);
});
function mousemove(event) {
if ($attrs.resizer == 'vertical') {
// Handle vertical resizer
var x = event.pageX;
if ($attrs.resizerMax && x > $attrs.resizerMax) {
x = parseInt($attrs.resizerMax);
}
$element.css({
left: x + 'px'
});
$($attrs.resizerLeft).css({
width: x + 'px'
});
$($attrs.resizerRight).css({
left: (x + parseInt($attrs.resizerWidth)) + 'px'
});
} else {
// Handle horizontal resizer
var y = window.innerHeight - event.pageY;
$element.css({
bottom: y + 'px'
});
$($attrs.resizerTop).css({
bottom: (y + parseInt($attrs.resizerHeight)) + 'px'
});
$($attrs.resizerBottom).css({
height: y + 'px'
});
}
}
function mouseup() {
$document.unbind('mousemove', mousemove);
$document.unbind('mouseup', mouseup);
}
};
});
