How to prevent body from scrolling with push-side menu



I am trying to properly implement a push-side menu plugin (Responsive Menu) into a wordpress theme. Based on SO @Congrim answer, I've managed to achieve a way to lock the body at scroll when push-menu is open (with all the elements including the header fixed) except the interactive links class=edge-ils edge-ils-with-scroll edge-ils-light which will still go Up at push-menu open.


body


header


class=edge-ils edge-ils-with-scroll edge-ils-light



I've saved this sequence into congrim.js file, I've enqueued the script into the theme in functions.php file:


congrim.js


functions.php


function lockScroll()
if ($('body').hasClass('lock-scroll'))
$('body').removeClass('lock-scroll');

else
$('body').addClass('lock-scroll');




/* I've implemented `onclick="lockScroll();"` in button element,
* using this sequence in the same congrim.js file:
*/

$(document).ready(function()
$('#responsive-menu-pro-button').click(function()
lockScroll();
);
);



Removing the jQuery wrap will not give any error in browser console (tested in Chrome) may be still a bad approach to wrapp the code like this in wordpress (?)
In these conditions, unfortunately, overflow: hidden; doesn't apply, at push-side menu open, I can't use this class in CSS file/section:


overflow: hidden;


.lock-scroll
overflow: hidden;



The code will allow me to use only


.lock-scroll
position: fixed;



The question:

Is there any possibility to force the code to implement overflow: hidden;* OR any other a workaround in order to have the interactive links class=edge-ils edge-ils-with-scroll edge-ils-light not going up at push-side menu open, to remain fixed at the position the viewer is clicked before opening the menu?


overflow: hidden;


class=edge-ils edge-ils-with-scroll edge-ils-light



Please focus on the interactive links issue only, the rest of the scene is fine (header and the logo are in place like it should be, the background pictures are acting like it should as well).


header


logo



LE: *overflow: hidden; it looks like will produce an unwanted body shifting effect at menu open/close, during the show/hide scrollbar, which is not happening in this stage.


overflow: hidden;


body



LE2: congrim.js file has been replaced with body-lock.min.js by Outsource WordPress, please see the solution below.


congrim.js


body-lock.min.js

Please check the solution given below.



Step 1: Add this CSS .scroll-lockposition:fixed !important;.


.scroll-lockposition:fixed !important;



Step 2: Add this JS.


$(document).ready(function()
var windowTop = 0;
var menuOpen = 0;
var offsetContainerList = 0;

$('#responsive-menu-pro-button').click(function()
var offsetScrollList = $('.edge-ils-item-link:first').offset().top;

if ($('html').hasClass('scroll-lock'))
$('#responsive-menu-pro-container').one("webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend",
function(event)
if (menuOpen==0)
menuOpen = 1;
$('html').removeClass('scroll-lock');
$('.edge-ils-content-table').css('top', eval(offsetContainerList)-40+'px'); //change image container top position
$('html').scrollTop(windowTop); //scroll to original position

else
menuOpen = 0;

);

else
windowTop = $(window).scrollTop();
offsetContainerList = $('.edge-ils-content-table').offset().top;
$('html').addClass('scroll-lock');
$('.edge-ils-content-table').css('top', -offsetScrollList + 'px'); //change image container top position

);
);



That's it!





Thank you SOOO much for this wonderful solution Sir, you're a Champ! It works like a charm, so smooth and nice. I really appreciate it, as much as others will appreciate this workaround for sure! All the best,

Please add the below code in your custom js file .


jQuery('#responsive-menu-pro-button').click(function()
var menu_active = jQuery(this).hasClass('is-active');
if(menu_active)
jQuery('body').css('position','fixed');
else
jQuery('body').css('position','static');

);



I hope it helps you.



Thanks





Thank you, I've updated the congrim.js file, adding your sequence below the existing code. It looks like this will lock the body not on menu-open but on menu close. Please have a look. Did I've made something wrong? here is the file.

Hello @typo_ please add only one code for lockScroll, remove all the reaming code in your file neuegrid.com/wp-content/themes/anders/assets/js/modules/plugins/…

Done! Should I add the line below the code as well jQuery.fn.init (...) ? or should I remove the .lock-scroll position: fixed; ? still not working Should I replace jQuery with $ ? (I know that's unusual for wordpress but I've managed to make other code work using $ instead of jQuery.

.lock-scroll position: fixed;


jQuery


$


$


jQuery



Your scroll isn't a natural navigator-based scroll, you have a JS somewhere swapping classes to emulate a scroll (edge-appeared,edge-up,edge-down).


edge-appeared


edge-up


edge-down



On the push-side menu opening, these classes are reset, overflow-hidden won't change that.


overflow-hidden



You need to find which JavaScript is swapping those classes and prevent it from doing so, I'd be glad to be of further help but you have so many JS files that it would take quite some time to go through all of these. If you succeed in making a Minimal, Complete, and Verifiable example please post it here.





Thanks but for the same reason I am unable to do that (because there are a lot of files involved into that scene); more than that, as I already said, I'm not a coder, I have no knowledge to do that, compiling and taking the essence from all that files ... Thanks for passing by and for your time, anyway. I appreciate it,

Maybe you can try asking the Responsive Menu support, it seems they already had this kind of issue here. Good luck !

I already had a discussion with @Peter Featherstone, but it looks like there are not much to do and I thought that there are people that had this issue and develop an solution; Thanks anyway.

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response.

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
