I have a select2 multiselect embedded inside a modal, but when I click on the select2 container to make the dropdown appear for the options, the dropdown doesn't appear where it should - rather it is half way up the page. When I zoom out of the page, it appears in the correct place, but zooming back in returns it to the wrong place.
What is the cause of this and what would be the best way to rectify it?
Normal View
Zoomed Out
Some things that I've already tried as suggested by other questions and answers:
Removed tabindex="-1" from the modal
Added style="overflow:hidden;" to <div class="modal-body">
Added dropdownParent to attach the dropdown to the modal dialog, rather than the HTML body
Attempted to change the z value in CSS
Edit
I have the following script on my page to fire the select2 container. This one its own causes the dropdown to function correctly.
document.addEventListener("DOMContentLoaded", function() {
// Select2
$("#hazards").each(function() {
$(this)
.wrap("<div class=\"position-relative\"></div>")
.select2({
placeholder: "Select hazards or search by typing above",
dropdownParent: $(this).parent()
});
});
});
I also have another script that when my select2 changes, pushes results to a different multiselect. The start of the code is this:
window.addEventListener('DOMContentLoaded', () => {
$('#hazards').select2();
let hprops = document.getElementById('hp_codes')
// document.querySelector('#hazards').addEventListener('change', e => {
// The hazards addEventListener was not firing?
$('#hazards').on('change', e => {
let options = e.target.options;
let hazards = [];
for (var i = 0, l = options.length; i < l; i++) {
if (options[i].selected) {
hazards.push(options[i].value);
}
}
... then if hazards results is XXXX push YYYY
When the second code is commented out and just the first, everything works but the results aren't pushed to my second multiselect. When the first is commented out and the second is left alone, it doesn't work as intended with the dropdown displaying out of position. So it looks like a js conflict.
How would I combine the first into the second whilst maintaining the function of the second script?
In the second script the Select2 plugin is re-initiazed with no other options:
$('#hazards').select2();
The correct code should be:
window.addEventListener('DOMContentLoaded', () => {
// Select2
$("#hazards").each(function() {
$(this)
.wrap("<div class=\"position-relative\"></div>")
.select2({
placeholder: "Select hazards or search by typing above",
dropdownParent: $(this).parent()
});
});
let hprops = document.getElementById('hp_codes')
// document.querySelector('#hazards').addEventListener('change', e => {
// The hazards addEventListener was not firing?
$('#hazards').on('change', e => {
let options = e.target.options;
let hazards = [];
for (var i = 0, l = options.length; i < l; i++) {
if (options[i].selected) {
hazards.push(options[i].value);
}
}
... then if hazards results is XXXX push YYYY
Hy everybody,
I'm working with dc.js and I think it's a genious tool ! However I have a issue I can't solve.
I'm using a dc.barchart and I want to launch a function of mine after a click on one bar, but I need to wait the end of the redraw of the barchart.
Order :
- my barchart is displayed
- I click on one bar
-> the barchart is redraw
-> only after the complete redraw, my function is launched
Where can I put my callback ? I can't find the corresponding code.
_chart.onClick = function (d) {
var filter = _chart.keyAccessor()(d);
dc.events.trigger(function () {
_chart.filter(filter);
_chart.redrawGroup();
alert("here is not working");
});
};
(...)
dc.redrawAll = function(group) {
var charts = dc.chartRegistry.list(group);
for (var i = 0; i < charts.length; ++i) {
charts[i].redraw();
}
alert("neither here");
if(dc._renderlet !== null)
dc._renderlet(group);
};
dc.events.trigger = function(closure, delay) {
if (!delay){
closure();
alert("neither neither here");
return;
}
dc.events.current = closure;
setTimeout(function() {
if (closure == dc.events.current)
closure();
}, delay);
};
Any idea ? I'm completely blocked right now :(
Thanks a lot for your help,
vanessa
If _chart is the name of your chart and you want to execute some function named my_function after finishing drawing, use the following piece of code after the declaration of the chart itself:
_chart.on("postRedraw", my_function);
Hope this is what you were looking for.
how would I go about tracking the number of click a user make on a site, and change the background accordingly, so for example: when a user lands of the first page the background is a small object, then as the user explores the site, the background changes, according to how many links have been clicked through, this would then cycle round.
these are the ideas i have come up with:
track the incoming source on each page, and if source was from this site, then add 1 to a counter stored in cookie, retrieve cookie and display corresponding background.
or to cause click on link to add one to counter in cookie.
any other suggestions or ideas? or is this bad practice or a very bad idea?
ps re research i tried and failed to find anything useful
You can do that easily with jQuery:
EDIT with $.cookie usage:
var totalClicks = ($.cookie('totalClicks' !== null) ? $.cookie('totalClicks') : 0;
var clicksLimit = 10;
$.cookie('clicksLimit', clicksLimit); // just so that you do not have to re-declare this variable on the other page.
$('body').on('click', '*', function() {
totalClicks++;
if(totalClicks >= clicksLimit) {
alert('do something here...');
// precise to your request:
$('body').css('background-color', '#f00'); // will turn body background to "red"
}
$.cookie('totalClicks', totalClicks);
});
It can be done using simple javascript, using jQuery would increase load on the server:
var clicks = 0;
var limit = 10;
document.onclick = function() {
if(clicks == 1) document.body.style.backgroundColor = "#FFF";
if(clicks == 2) document.body.style.backgroundColor = "#EEE";
if(clicks == 3) document.body.style.backgroundColor = "#DDD";
if(clicks == 4) document.body.style.backgroundColor = "#CCC";
....
clicks++;
};
you can do this
// Get click amount from localStorage or use 0 if it doesn't exist
var clicks = localStorage['clicks'] || 0;
// Add the click className to the body first
document.body.className = 'style-' + clicks;
// Set a eventListener
document.addEventListener('click', function(){
// clicks + 1
clicks++;
// Add new class name
document.body.className = 'style-' + clicks;
}, false);
// When the window is about to be closed save the clicks in localStorage
window.onbeforeunload = function(){
localStorage['clicks'] = clicks;
};
here is a fiddle ignore the buttons and just look at the body tag in dev tools
Fiddle
you may have to do some cross browser work but it's the idea.
there is a polyfill for localStorage here https://gist.github.com/remy/350433
But--- if the browser doesn't support localStorage then this doesn't seem like a high priority feature for the site so the only thing that won't work it the state change on reload
I'm thinking about making a website for my business where all the content is on one long page which the user will not be able to scroll through and you will have to navigate through the site by clicking the buttons which will then animate between the anchor points to the next page. I'm will make a long image with the home point being an office and the user then can go up into the sky then space for different pages.
So how would I stop the user from being able to scroll and how would I make it animate or slowly scroll between each anchor. Would it be possible to scroll horizontally as well?
I would try to solve your problem by disabling temporally the scrolling functionality of the browser. You can achieve this by unbinding any event listeners associated with keypress or mouse scroll.
You can deny the mouse scroll to get triggered by preventing it's default action associated with the event handler. Technically this is how can be done in Javascript:
window.onload = function() {
if (window.addEventListener) {
window.addEventListener('DOMMouseScroll', disableScroll, false);
} else if (window.attachEvent) { //IE event handler
window.attachEvent('DOMMouseScroll', disableScroll);
} else {
window.onscroll = disableScroll;
}
}
function disableScroll(event) {
event = event || window.event;
if (event.preventDefault) {
event.preventDefault(); // prevent the default action to get triggered\
}
event.returnValue = false; // IE method
}
var keys = [37, 38, 39, 40];
function onKeydown(event) {
var e = event || window.event;
for (var i = 0, len = keys.length; i < len; i++) {
if (e.keyCode == keys[i]) {
console.log("Forbidden event");
e.preventDefault();
}
}
}
document.onkeydown = onKeydown;
Then you can construct your code by using anchor points and on click advanced to the desired place. That's it.
I have found a MooTools version of Nivoo Slider that (in theory) will work with our MooTools dropdown menu. However, the menu is using MooTools 1.2.x, and Nivoo is using 1.3.2 or 1.4.0. Every time I try and use both the menu and the slider, the menu stops working.
Are the versions of the MooTools framework not backward compatible?
Also, are these plugins compatible or is one overriding the other?
I don't know enough about JS to correct my errors or rewrite the function call. Is there a good beginner's tutorial for this?
window.addEvent('domready', function () {
var menu = new UvumiDropdown('dropdown-demo');
// initialize Nivoo-Slider
new NivooSlider($('slider'), {
directionNavHide: true,
effect: 'wipeDown',
interval: 1000
});
});
In trying to convert without compatibility, here are instructions that I was not sure how to implement.
Instruction
:: Line of 1.2 code
$clear => use the native clearTimeout when using fn.delay, use clearInterval when using fn.periodical.
:: $clear(a.retrieve('closeDelay'))
myFn.create => Use the according functions like .pass, .bind, .delay, .periodical
:: this.createSubmenu(this.menu)
myFn.bind(this, [arg1, arg2, arg3]) => myFn.bind(this, arg1, arg2, arg3) OR myFn.pass([arg1, arg2, arg3], this)
:: this.domReady.bind(this)
$$ now only accepts a single selector, an array or arguments of elements
:: $$(b,b.getChildren('li')
These instructions are with compatibility. I'm trying both.
myElement.get('tween', options); // WRONG
myElement.set('tween', options).get('tween'); // YES, INDEED.
:: this.menu.get('tag')!='ul'
:: this.menu.getElement('ul')
OK I tested the UvumiDropdown latest build with mootools 1.4.x and it worked fine as long as I included a Mootools more build that includes Fx.Elements
Hope this helps

MooTools follows SemVer (Semantic Versioning), meaning that a minor version number (x.Y.z) bump is not guaranteed to be backward-compatible (and is usually not).
However, new versions come with a compatibility layer. Just tick the box on the MooTools Core builder if you really can't upgrade your code. You should though avoid to do such a thing, it is bad for performance and potentially forward-compatibility.
As for a tutorial, the best way to learn how to upgrade code from one version to the other is to read the changelog of the 1.3 to learn about the differences with 1.2, and from the 1.3 to the 1.4 if you want to upgrade to the latest version. From this knowledge, rewrite all calls that make use of outdated APIs.
It looks like a daunting task at first, but it usually goes very quickly (actually, in this precise case, it is most often about rewriting Hash references and .each calls). It might be hard if you're learning JS, but it will definitely be a very rewarding experience in JS, and especially in MooTools, as you'll learn about what makes a code ”Mooish” :)
