Link that preselect dropdown option with jQuery

I have a select with options that have values that are populated with jQuery based on data attributes from divs. When a user select an option, the div with the data attribute that matches the value of the option is displayed. Now I'm trying to create a deep linking option, so when I have a url like https://my-site.com/page/#option-2 the option-2 is preselected in the select and the div with data attribute option-2 is displayed. So far I have this javascript:
$(window).on('load', function() {
let urlHash = window.location.hash.replace('#','');
console.log(urlHash);
if ( urlHash ) {
$('.dropdown').val(urlHash);
$('body').find('.location').removeClass('is-active');
$('body').find(`.location[data-location-hash=${urlHash}]`).addClass('is-active');
}
});
If I enter the url https://my-site.com/page/#option-2 the site goes in infinite loop and never loads without displaying any error in the console.. If I refresh the page while loading, the console.log is displayed with the correct string that I'm expecting, but the .location[data-location-hash=option-2] is not displayed and the option is not selected... I'm using the same code for the change function of the dropdown and is working, but it's not working in the load function.. Is there anything I'm missing?
JSFiddle, if it's of any help:

Your site is looping because you are doing a window.location.replace To get the urlHash you should use
$(window).on('load', function() {
var href = location.href; // get the url
var split = href.split("#"); // split the string
let urlHash = split[1]; // get the value after the hash
if ( urlHash ) {
$('.dropdown').val(urlHash);
$('body').find('.location').removeClass('is-active');
$('body').find('.location[data-location-hash='+urlHash+']').addClass('is-active');
}
});

Solved it by using a function instead of $(window).on('load').. Also added $( window ).on( 'hashchange', function( ) {}); to assure that the js will run again after the hash is changed.

the tooltip in bootstrap doesn't work after ajax

I have a file named index.php, which in I include another file named file1.php (in index.php I include all necessary files for jQuery, js etc.).
In file1.php I have a table with buttons which each opens a modal. the information in the modal is from an ajax call for file2.php. in file2.php I create a table. In the table I have the cell :
<button class='btn btn-default tooltip-default' data-toggle='tooltip' data-trigger='hover' data-placement='top' data-content='content' data-original-title='Twitter Bootstrap Popover'>AAA</button>
and, well, the tooltip doesn't work.
but, when I copy this and get it to file1.php, bellow the table, the tooltip does work.
Can anyone help me fix the tooltip ?
Thx.

Use selector on exist element like body
$('body').tooltip({selector: '[data-toggle="tooltip"]'});

I think you need to initialize the tooltip on the newly arrived data, e.g.
$('[data-toggle="tooltip"]').tooltip();
Place this code to your AJAX success handler, after the DOM manipulation.

You will have to put the tooltip initialization in Ajax callback function:
$.ajax({
method: "POST",
url: "some.php"
}).done(function( msg ) {
$('[data-toggle="tooltip"]').tooltip();
});
-OR-
instead of putting the initialization code in every Ajax callback function
you can implement it globally using the ajaxComplete event:
/* initializate the tooltips after ajax requests, if not already done */
$( document ).ajaxComplete(function( event, request, settings ) {
$('[data-toggle="tooltip"]').not( '[data-original-title]' ).tooltip();
});
This code will initialize the tooltip for every node which has the data-toggle="tooltip" attribute defined but do not have the attribute "data-original-title" (i.e tooltip not initialized).

I've tried everything and nothing worked for me.
So I took a closer look at tooltip when click* and found out that each time the shown.bs.tooltip is fired a aria-describedby property appears and its value changes every time.
So, my approach (and it works) is to change the content of this dynamic element.
I got this code:
$('body').on('shown.bs.tooltip', function(e) {
var $element = $(e.target);
var url = $element.data('url');
if (undefined === url || url.length === 0) {
return true;
}
var $describedByContent = $('#' + $element.attr('aria-describedby')).find('.tooltip-inner');
if ($element.attr('title').length > 1) {
$describedByContent.html($element.attr('title'));
return true;
}
$.ajax({
url: url,
method: 'GET',
beforeSend: function () {
$element.attr('title', 'Cargando... espere por favor.');
$describedByContent.html($element.attr('title'));
}
}).done(function (data) {
$element.attr('title', JSON.stringify(data));
$describedByContent.html($element.attr('title'));
});
return true;
});
In my case my tooltip has a data-url attribute to take the data for the title.
The original title is '-', and I don't want an ajax call every time I click* the element, just the first time.
To me it's not useful to make an ajax every time because I don't expect the data to change that fast.
The dynamic created element has an element with the class .tooltip-inner, so we just need to replace its content.
Hope this might help.
*click: I chose the click event because the default hover sometimes make the system turn crazy and the show.bs.tooltip was fired forever, switching its between the default and new value.

You can do this in one of these two ways:
you can write an ajaxComplete function so that every time after an ajax call completed it reinitialize the tooltip over and over again. This is useful when in most of your pages you have datatables and want to initialize the tooltip after every ajax datatable call:
$(document).ajaxComplete(function() {
$("[data-toggle=tooltip]").tooltip();
});
Or you can call tooltip function after ajax success callback:
function tool_tip() {
$('[data-toggle="tooltip"]').tooltip()
}
tool_tip(); // Call in document ready for elements already present
$.ajax({
success : function(data) {
tool_tip(); // Call function again for AJAX loaded content
}
})

I set up my tool tip by placement like so:
function setUpToolTipHelpers() {
$(".tip-top").tooltip({
placement: 'top'
});
$(".tip-right").tooltip({
placement: 'right'
});
$(".tip-bottom").tooltip({
placement: 'bottom'
});
$(".tip-left").tooltip({
placement: 'left'
});
}
initialize this with a document ready call:
$(document).ready(function () {
setUpToolTipHelpers();
});
This way I can determine the placement of the tool tip, and I only have to assign the tip with using a class and title:
<td class = "tip-top", title = "Some description">name</td>
Then I call, "setUpToolTipHelpers()" inside my success ajax function. Or you can call it on the complete function as well. This seems to work well for me.

run
$('#ding_me_tooltip').tooltip('dispose');
$('#ding_me_tooltip').tooltip();
after the ajax where #ding_me_tooltip is your selector

jQuery - load from another page after all elements are loaded

I want to display the rating of a product, witch is on the product page in div with id rating, on the category page, so I made a script below:
$('.product').each(function(){
var url = $(this).find('a').attr('href');
$(this).prepend('<div class="rating"></div>');
$(this).find('.rating').load(url +'#rating');
});
The problem is, that the rating on the product page is generated with another script, so the element #rating is not present on the site from the start, so after doing some search I tried adding ajaxcomplete function:
$('.product').each(function(){
var url = $(this).find('a').attr('href');
$(this).prepend('<div class="rating"></div>');
$(this).ajaxComplete(function(nxt) {
$(this).find('.rating').load(url +'#rating');
nxt();
});
});
But that also doesn't seem to work, so I'm wondering is there any solution for this to work?
Thanks

You need to load the script that does the rating using jQuery getScript. This way you can put processing dependent on the rating script in the success handler of the getScript call.
The code will look something like this:
$.getScript( "rating.js", function( data, textStatus, jqxhr ) {
console.log( "rating complete" );
$('.product').each(function(){
var url = $(this).find('a').attr('href');
$(this).find('.rating').load(url +'#rating');
}
});

Tablesort Reload Table Data on Click using Ajax?

I'm trying to reload the table data (rows/TRs) when the user clicks a link, I can add more/append? the data but I cannot seem to delete the old table data before inserting the new table data.
(BTW: the updatetable.php contains all of the (TR's) for that table)
Here is what I'm trying to do:
$(function() {
$("#append").click(function() {
var test;
$.get('updatetable.php', function(data) {
test = data;
$("#tablesorter-demo").remove();
$("#tablesorter-demo").append(test);
$("#tablesorter-demo").trigger.update(); // <--- I think that error is here, I tried to take out the trigger. but it still doesn't work ?
alert(test);
//return false;
});
});
The href code is: <a id="append" href="#">Refresh Page</a>

Try this:
$(function() {
$("#append").click(function(e) {
e.preventDefault();
$.get('updatetable.php', function(data) {
$("#tablesorter-demo").find('tbody').html('').append(data);
});
});
});

#Adam Putinski Not if one is using Internet Explorer then it looks like this code will not work the table and rows show but nothing else can be done with them, also the $('[title!=""]').qtip({
}); will only work until the user loads the data from the updatetable.php page then it will not work anymore ?

Load Html Content if not exist JQuery AJAX

I have a page with 3 buttons. >Logos >Banners >Footer
When any of these 3 buttons clicked it does jquery post to a page which returns HTML content in response and I set innerhtml of a div from that returned content . I want to do this so that If I clicked Logo and than went to Banner and come back on Logo it should not request for content again as its already loaded when clicked 1st time.
Thanks .

Sounds like to be the perfect candidate for .one()
$(".someItem").one("click", function(){
//do your post and load the html
});
Using one will allow for the event handler to trigger once per element.

In the logic of the click handler, look for the content having been loaded. One way would be to see if you can find a particular element that comes in with the content.
Another would be to set a data- attribute on the elements with the click handler and look for the value of that attribute.
For example:
$(".myElements").click(function() {
if ($(this).attr("data-loaded") == false {
// TODO: Do ajax load
// Flag the elements so we don't load again
$(".myElements").attr("data-loaded", true);
}
});
The benefit of storing the state in the data- attribute is that you don't have to use global variables and the data is stored within the DOM, rather than only in javascript. You can also use this to control script behavior with the HTML output by the server if you have a dynamic page.

try this:
HTML:
logos<br />
banner<br />
footer<br />
<div id="container"></div>
JS:
$(".menu").bind("click", function(event) {
event.stopPropagation();
var
data = $(this).attr("data");
type = $(this).attr("type");
if ($("#container").find(".logos").length > 0 && data == "logos") {
$("#container").find(".logos").show();
return false;
}
var htmlappend = $("<div></div>")
.addClass(type)
.addClass(data);
$("#container").find(".remover-class").remove();
$("#container").find(".hidde-class").hide();
$("#container").append(htmlappend);
$("#container").find("." + data).load("file_" + data + "_.html");
return false;
});

I would unbind the click event when clicked to prevent further load requests
$('#button').click(function(e) {
e.preventDefault();
$('#button').unbind('click');
$('#result').load('ajax/test.html ' + 'someid', function() {
//load callback
});
});
or use one.click which is a better answer than this :)

You could dump the returned html into a variable and then check if the variable is null before doing another ajax call
var logos = null;
var banners = null;
var footer = null;
$(".logos").click(function(){
if (logos == null) // do ajax and save to logos variable
else $("div").html(logos)
});

Mark nailed it .one() will save extra line of codes and many checks hassle. I used it in a similar case. An optimized way to call that if they are wrapped in a parent container which I highly suggest will be:
$('#id_of_parent_container').find('button').one("click", function () {
//get the id of the button that was clicked and do the ajax load accordingly
});
