Add the openonleft option to the mbmenu control of jquery to open the submenu on the left of the main menu.

Recently I tried jquery's mbmenu control to display the control, which is quite powerful. I am a super JavaScript white, and I am also a little white on jquery. I can use this control with a good attitude. However, you may need to display a sub-menu on the left of the main menu. However, mbmenu displays sub-Menus under the main menu by default. You can also set it to display sub-menus on the right of the main menu, however, there is no function to display sub-menus on the left of the main menu. What should I do? You can only do it yourself. Fortunately, there is only one level sub-menu currently.

The Code involved in the modification is as an archive.

First, add an openonleft parameter. The first line is the added code.

 1 options: {
 2     template: "yourMenuVoiceTemplate", // the url that returns the menu voices via ajax. the data passed in the request is the "menu" attribute value as "menuId"
 3     additionalData: "",
 4     menuSelector: ".menuContainer",
 5     menuWidth: 400,
 6     openOnRight: false,
 7     openOnLeft: false,
 8     containment: "window",
 9     iconPath: "ico/",
10     hasImages: true,
11     fadeInTime: 100,
12     fadeOutTime: 200,
13     menuTop: 0,
14     menuLeft: 0,
15     submenuTop: 0,
16     submenuLeft: 4,
17     opacity: 1,
18     openOnClick: true,
19     closeOnMouseOut: false,
20     closeAfter: 500,
21     minZindex: "auto", // or number
22     hoverIntent: 0, //if you use jquery.hoverIntent.js set this to time in milliseconds; 0= false;
23     submenuHoverIntent: 200, //if you use jquery.hoverIntent.js set this to time in milliseconds; 0= false;
24     onContextualMenu: function () { } //it pass 'o' (the menu you clicked on) and 'e' (the event)
25 },

　　

The following code contains the processing of openonleft. Lines 18th to 22 are the added code.

 1 switch (type)
 2 {
 3     case "sm":
 4         t = $(this).position().top + op.options.submenuTop;
 5 
 6         l = $(this).position().left + $(this).width() - op.options.submenuLeft;
 7         break;
 8     case "cm":
 9         t = this.mouseY - 5;
10         l = this.mouseX - 5;
11         break;
12     default:
13         if (op.options.openOnRight)
14         {
15             t = $(this).offset().top - ($.browser.msie ? 2 : 0) + op.options.menuTop;
16             l = $(this).offset().left + $(this).outerWidth() - op.options.menuLeft - ($.browser.msie ? 2 : 0);
17         }
18         else if (op.options.openOnLeft)
19         {
20             t = $(this).offset().top - ($.browser.msie ? 2 : 0) + op.options.menuTop;
21             l = $(this).offset().left - $(this.menuContainer).outerWidth() - op.options.menuLeft - ($.browser.msie ? 2 : 0);
22         }
23         else
24         {
25             t = $(this).offset().top + $(this).outerHeight() - (!$.browser.mozilla ? 2 : 0) + op.options.menuTop;
26             l = $(this).offset().left + op.options.menuLeft;
27         }
28         break;
29 }
