Cancel a draggable 'dragmove' on kineticjs? -


i have set limit movement of circle when coordinate 'y' on pixel 'y-15', on specific coordinate (x,y). i've tried use 'draggable=true' event 'mouseup' , 'mousedown', can't results need. can me, please?

my code is:

circle.on('mouseover',function(){     this.setattr('draggable',true);   });    circle.on('dragmove',function(e){      var mousepos = stage.getmouseposition();     var x = mousepos.x;     var y = mousepos.y;      if(y < y2- 15){        //do     }     else{       this.setattr('draggable',false);     }    });

if understand correctly, want dragboundfunc.

see tutorial:

http://www.html5canvastutorials.com/kineticjs/html5-canvas-drag-and-drop-bounds-tutorial-with-kineticjs/

    // bound below y=50     var bluegroup = new kinetic.group({       x: 100,       y: 70,       draggable: true,       dragboundfunc: function(pos) {         var newy = pos.y < 50 ? 50 : pos.y;         return {           x: pos.x,           y: newy         };       }     });

you'll have modify code y-15 when grab mouse coordinates, , set dragboundfunc reflect coordinates clicked on.

if you're trying limit y-axis on known fixed y value, becomes easier, how tutorial shows you, except have change coordinate want limit y to.

check 1 quick reference too:

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
