I suspect my question may be a bit obtuse, and I apologize. Here is what I am trying to achieve:
I am using this multi-level push menu, and it works fine out of the box. However, I would like the multi-level menu to close after a modal is submitted and closed. I am having a difficult time figuring out how to trigger this menu to close.
So, on to some code. Up first, the Javascript that runs the menu itself.
mlPushMenu.prototype = {
defaults : {
// overlap: there will be a gap between open levels
// cover: the open levels will be on top of any previous open level
type : 'overlap', // overlap || cover
// space between each overlaped level
levelSpacing : 40,
// classname for the element (if any) that when clicked closes the current level
backClass : 'mp-back'
},
_init : function() {
// if menu is open or not
this.open = false;
// level depth
this.level = 0;
// the moving wrapper
this.wrapper = document.getElementById( 'mp-pusher' );
// the mp-level elements
this.levels = Array.prototype.slice.call( this.el.querySelectorAll( 'div.mp-level' ) );
// save the depth of each of these mp-level elements
var self = this;
this.levels.forEach( function( el, i ) { el.setAttribute( 'data-level', getLevelDepth( el, self.el.id, 'mp-level' ) ); } );
// the menu items
this.menuItems = Array.prototype.slice.call( this.el.querySelectorAll( 'li' ) );
// if type == "cover" these will serve as hooks to move back to the previous level
this.levelBack = Array.prototype.slice.call( this.el.querySelectorAll( '.' + this.options.backClass ) );
// event type (if mobile use touch events)
this.eventtype = mobilecheck() ? 'touchstart' : 'click';
// add the class mp-overlap or mp-cover to the main element depending on options.type
classie.add( this.el, 'mp-' + this.options.type );
// initialize / bind the necessary events
this._initEvents();
},
_initEvents : function() {
var self = this;
// the menu should close if clicking somewhere on the body
var bodyClickFn = function( el ) {
self._resetMenu();
el.removeEventListener( self.eventtype, bodyClickFn );
};
// open (or close) the menu
this.trigger.addEventListener( this.eventtype, function( ev ) {
ev.stopPropagation();
ev.preventDefault();
if( self.open ) {
self._resetMenu();
}
else {
self._openMenu();
// the menu should close if clicking somewhere on the body (excluding clicks on the menu)
document.addEventListener( self.eventtype, function( ev ) {
if( self.open && !hasParent( ev.target, self.el.id ) ) {
bodyClickFn( this );
}
} );
}
} );
// opening a sub level menu
this.menuItems.forEach( function( el, i ) {
// check if it has a sub level
var subLevel = el.querySelector( 'div.mp-level' );
if( subLevel ) {
el.querySelector( 'a' ).addEventListener( self.eventtype, function( ev ) {
ev.preventDefault();
var level = closest( el, 'mp-level' ).getAttribute( 'data-level' );
if( self.level <= level ) {
ev.stopPropagation();
classie.add( closest( el, 'mp-level' ), 'mp-level-overlay' );
self._openMenu( subLevel );
}
} );
}
} );
// closing the sub levels :
// by clicking on the visible part of the level element
this.levels.forEach( function( el, i ) {
el.addEventListener( self.eventtype, function( ev ) {
ev.stopPropagation();
var level = el.getAttribute( 'data-level' );
if( self.level > level ) {
self.level = level;
self._closeMenu();
}
} );
} );
// by clicking on a specific element
this.levelBack.forEach( function( el, i ) {
el.addEventListener( self.eventtype, function( ev ) {
ev.preventDefault();
var level = closest( el, 'mp-level' ).getAttribute( 'data-level' );
if( self.level <= level ) {
ev.stopPropagation();
self.level = closest( el, 'mp-level' ).getAttribute( 'data-level' ) - 1;
self.level === 0 ? self._resetMenu() : self._closeMenu();
}
} );
} );
},
_openMenu : function( subLevel ) {
// increment level depth
++this.level;
// move the main wrapper
var levelFactor = ( this.level - 1 ) * this.options.levelSpacing,
translateVal = this.options.type === 'overlap' ? this.el.offsetWidth + levelFactor : this.el.offsetWidth;
this._setTransform( 'translate3d(' + translateVal + 'px,0,0)' );
if( subLevel ) {
// reset transform for sublevel
this._setTransform( '', subLevel );
// need to reset the translate value for the level menus that have the same level depth and are not open
for( var i = 0, len = this.levels.length; i < len; ++i ) {
var levelEl = this.levels[i];
if( levelEl != subLevel && !classie.has( levelEl, 'mp-level-open' ) ) {
this._setTransform( 'translate3d(-100%,0,0) translate3d(' + -1*levelFactor + 'px,0,0)', levelEl );
}
}
}
// add class mp-pushed to main wrapper if opening the first time
if( this.level === 1 ) {
classie.add( this.wrapper, 'mp-pushed' );
this.open = true;
}
// add class mp-level-open to the opening level element
classie.add( subLevel || this.levels[0], 'mp-level-open' );
},
// close the menu
_resetMenu : function() {
this._setTransform('translate3d(0,0,0)');
this.level = 0;
// remove class mp-pushed from main wrapper
classie.remove( this.wrapper, 'mp-pushed' );
this._toggleLevels();
this.open = false;
},
// close sub menus
_closeMenu : function() {
var translateVal = this.options.type === 'overlap' ? this.el.offsetWidth + ( this.level - 1 ) * this.options.levelSpacing : this.el.offsetWidth;
this._setTransform( 'translate3d(' + translateVal + 'px,0,0)' );
this._toggleLevels();
},
// translate the el
_setTransform : function( val, el ) {
el = el || this.wrapper;
el.style.WebkitTransform = val;
el.style.MozTransform = val;
el.style.transform = val;
},
// removes classes mp-level-open from closing levels
_toggleLevels : function() {
for( var i = 0, len = this.levels.length; i < len; ++i ) {
var levelEl = this.levels[i];
if( levelEl.getAttribute( 'data-level' ) >= this.level + 1 ) {
classie.remove( levelEl, 'mp-level-open' );
classie.remove( levelEl, 'mp-level-overlay' );
}
else if( Number( levelEl.getAttribute( 'data-level' ) ) == this.level ) {
classie.remove( levelEl, 'mp-level-overlay' );
}
}
}
}
The method I would like to invoke would be _resetMenu. I have tried this a couple of ways. The primary was trying to trigger the click event of the button that opens the menu:
<a href="#" id="trigger" class="show-root-menu"><i class="fa fa-reorder"></i></a>
However:
$('#trigger').trigger('click');
does not work as expected. I would expect this to be fired:
// open (or close) the menu
this.trigger.addEventListener( this.eventtype, function( ev ) {
ev.stopPropagation();
ev.preventDefault();
if( self.open ) {
self._resetMenu();
}
else {
self._openMenu();
// the menu should close if clicking somewhere on the body (excluding clicks on the menu)
document.addEventListener( self.eventtype, function( ev ) {
if( self.open && !hasParent( ev.target, self.el.id ) ) {
bodyClickFn( this );
}
} );
}
} );
In this case, this.eventtype is 'click'.
I suspect this may have something to do with how this functionality is coded with an object. While I have decent Javascript skills, I have not had much exposure to using it in this manner.
I am instantiating the menu thusly:
new mlPushMenu(document.getElementById('mp-menu'), document.getElementById('trigger'));
I realize I could extract this method, but that seems to violate some best practices in general.
Any suggestions will be most appreciated!
