I want to get the text content of an element inside $(this) on jQuery

function newFunc(){
excuseDivs = " "
excuseArrayItem = excuse + " : " + "<span class='excuseDivTime'>" + endTime + "</span>";
excuseArray.unshift(excuseArrayItem)
excuseArray.forEach(function(excuse){
excuseDivs +="<div class='excuse-div'>"+excuse+"</div>"
})
I want to add a click listener to the div that this function creates. I want that click listener to get the text content of the span inside the div (class of excuseDivTime). Is there some way to get something like ($(this) > span).textContent ??

You can do this fairly easy in either plain JavaScript or stick with jQuery.
You need to query for the span under the clicked div.
If you are using jQuery, stick with jQuery method calls e.g. .text() instead of .textContent.
// Plain JavaScript
document.getElementById('MyDiv').addEventListener('click', function(e) {
alert(e.currentTarget.querySelector('span').textContent);
});
// jQuery Version
$('#MyDiv').on('click', function(e) {
alert($(this).find('span').text());
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="MyDiv">Click me! <span>This text will show in an alert.</span></div>

Use find() or children()
$(document).on('click', '.excuse-div', function() {
console.log( $(this).find('.excuseDivTime').text() );
});

Get child div of existing div using anchors next element without ID or class using JQuery

As you can see below $(nextDiv + ' > div').eq(i).fadeIn('slow'); does not work as it seems to be malformed. nextDiv is on inspection the div below the anchor, how do I achieve getting the two divs that sit inside it?
HTML:
Sub Click
<div>
<div>I want this to fade in on the click</div>
<div>Followed by this etc.</div>
</div>
Javascript:
function subClick(myAnchor)
{
var nextDiv = $(myAnchor).next();
function showDiv(i) {
if (i > 2) return;
setTimeout(function () {
$(nextDiv + ' > div').eq(i).fadeIn('slow');
showDiv(++i);
}, 50);
}
showDiv(0);
}

You are trying to concatenate a string with jQuery, that won't provide a valid selector. The concatenation would provide something like "[object Object] > div" which doesn't select any elements in your code.
Instead, get the div children using children() method on the jQuery nextDiv object.
nextDiv.children('div').eq(i).fadeIn('slow');
If there are only two divs then you can reduce the code using delay() method.
function subClick(myAnchor) {
var nextDivs = $(myAnchor).next().children();
// if you want to do the animation after the first then
// use the below code, where second animation initializing within
// the first animation success callback, which also provides a 50ms
// delay for second animation(avoid .delay(50) if you dont nedd that delay)
// nextDivs.eq(0).fadeIn('slow', function() {
// nextDivs.eq(1).delay(50).fadeIn('slow');
// });
// in case you just want to provide a 50ms delay
// between animation then use, your code does this
nextDivs.eq(0).fadeIn('slow');
nextDivs.eq(1).delay(50).fadeIn('slow');
}

var nextDiv = $(myAnchor).next(); then nextDiv is an object not a selector. If you want to access its div children use this:
nextDiv.children('div').eq(i).fadeIn('slow');

Where do I put $(this) in the function?

Since I want to use classes instead of id's in these functions(I have three of the same function with different things I want to .append) I am sure I need to put $(this) in those functions somewhere to only trigger only ONE function on button click and not all three of them. but I am not sure because I am a total beginner in jquery/js, so I would appreciate some help.
$(document).ready(function () {
$(".onclick").click(function () {
$('#favorites').append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
http://codepen.io/anon/pen/JYxqEw - HTML And the Jquery Code

$('.onclick') selects all the elements with a class of onclick. That means that, whenever something with class="onclick" is clicked, that function will fire.
If you want all of those elements to append that exact HTML to the #favorites element, then you can leave your code as-is.
However, if what you're trying to do is append that html to the clicked element, that is when you'd use $(this) -- that selects the element you clicked with jQuery, then you can append directly to that element ie:
$(document).ready(function () {
$(".onclick").click(function () {
// this will append the HTML to the element that triggered the click event.
$(this).append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
EDIT
so to insert the contents of each .onclick into #favorites, you'll need to use the innerHTML value of the DOM node. example fiddle:
http://jsbin.com/qazepubuzu/edit?html,js,output
When you select something with jQuery, you're actually getting back not just the DOM node, but a jQuery object -- this object contains both a reference to the actual DOM node ([0]), as well as a jquery object ([1]).
So to select the DOM node with $(this), you target the node: $(this)[0]. Then you can use .innerHTML() to grab the HTML contents of the node and do as you like.
Final result:
$(function () {
$('.onclick').click(function () {
$('#favorites').append( $(this)[0].innerHTML );
});
});

So the building blocks are not that complex, but I think you're a novice jQuery developer and so you may not be clear on the difference between jQuery and JS yet.
$(selector, context) allows us to create a jQuery collection for a CSS selector which is the child of a current context DOM node, though if you do not specify one there is an automatic one (which is document.body, I think). Various functions iterating over jQuery collections make the particular element available as this within the JavaScript. To get to the strong element from the .onclick element in the HTML fragment you need to travel up in the hierarchy, then to the appropriate element. Then, we can collect the text from the element. We can do this in either JS or jQuery.
To do this with simply jQuery:
// AP style title case, because Chicago is too crazy.
var to_title_case = (function () { // variable scope bracket
var lower_case = /\b(?:a|an|the|and|for|in|so|nor|to|at|of|up|but|on|yet|by|or)\b/i,
first_word = /^(\W*)(\w*)/,
last_word = /(\w*)(\W*)$/;
function capitalize(word) {
return word.slice(0, 1).toUpperCase() + word.slice(1).toLowerCase();
}
function capitalize_mid(word) {
return lower_case.exec(word) ? word.toLowerCase() : capitalize(word);
}
return function to_title_case(str) {
var prefix = first_word.exec(str),
str_minus_prefix = str.slice(prefix[0].length),
suffix = last_word.exec(str_minus_prefix),
center = str_minus_prefix.slice(0, -suffix[0].length);
return prefix[1] + capitalize(prefix[2]) + center.replace(/\w+/g, capitalize_mid)
+ capitalize(suffix[1]) + suffix[2];
};
})();
$(document).ready(function() {
$(".onclick").click(function () {
var text = $(this).parents('.ui-grid-a').find('.ui-block-a').text();
var html = '<div data-role="main"class="ui-content">'
+ '<div class="ui-grid-b"><div class="ui-block-a">'
+ to_title_case(text) + '</div><div class="ui-block-b">More Info</div>'
+ '<div class="ui-block-c">Unfavorite</div></div></div>';
$("#favorites").append(html);
});
});

javascript change css by tag index

in my code i have around 11 image tags , all of them have an id of "#bigimage"
i want to change the style of an image on each click on a specific button for the specific image
meaning on the first click changing the #bigimage [0]
second click changing the #bigimage [1]
etc...
this is what i did:
<script>
//click event
$('.jssora05r').click(function() {
var abc=$('#bigimag').length;
var ind=0
$("#bigimag").index(ind).css("display", "block !important");
ind++;
});
</script>
it's not working, could someone help me?

just declare ind out side of the click event
also you need to change that id selector to some class selector and add same class to all images
<script>
var int = 0;
//click event
$('.jssora05r').click(function() {
// change id to some class
var abc=$('.someclass').length;
$(".someclass").index(ind).css("display", "block !important");
ind++;
});

javascript set element background color

i have a little javascript function that does something when one clicks on the element having onclick that function.
my problem is:
i want that, into this function, to set a font color fot the html element having this function onclick. but i don't suceed. my code:
<script type="text/javascript">
function selecteazaElement(id,stock){
document.addtobasket.idOfSelectedItem.value=id;
var number23=document.addtobasket.number;
number23.options.length=0;
if (stock>=6) stock=6;
for (i=1;i<=stock;i++){
//alert ('id: '+id+'; stock: '+stock);
number23.options[number23.options.length]=new Option(i, i);
}
}
</script>
and how i use it:
<li id = "product_types">
<a href="#" onclick='selecteazaElement(<?= $type->id; ?>,<?= $type->stock_2; ?>);'><?= $type->label; ?></a>
</li>
any suggestions? thanks!
i have added another function (jquery one) that does partially what i need. the new problem is: i want that background color to be set only on the last clicked item, not on all items that i click. code above:
$(document).ready(function() {
$('.product_types > li').click(function() {
$(this)
.css('background-color','#EE178C')
.siblings()
.css('background-color','#ffffff');
});
});
any ideas why?
thanks!

I would suggest
$(document).ready(function() {
$('.product_types > li').click(function() {
$('.product_types > li').css('background-color','#FFFFFF');
$(this).css('background-color','#EE178C');
});
});

Your element could have this code:
<li id = "product_types" onclick="selecteazaElement(this);" <...> </li>
To change the foreground color of that element:
function selecteazaElement(element)
{
element.style.foregroundColor="#SOMECOLOR";
}
If you want to change the background color on only the last element clicked, each element must have a different id. I'd suggest naming each one something like product_types1, product_types2, ..., product_typesN, and so on. Then have a reset function:
function Reset()
{
for (var i = 1; i <= N; i = i + 1)
{
document.getElementById('product_types'+i).style.backgroundColor="#RESETCOLOR";
}
}
When you call your selecteazaElement(this) function, first call the Reset function, then set the new element:
function selecteazaElement(element)
{
Reset();
element.style.backgroundColor="#SOMECOLOR";
}
This way all of the elements that start with product_types followed by a number will be reset to one particular color, and only the element clicked on will have the background changed.

The 'scope' of the function when invoked is the element clicked, so you should be able to just do:
function selecteazaElement(id,stock){
document.addtobasket.idOfSelectedItem.value=id;
var number23 = document.addtobasket.number;
number23.options.length=0;
if (stock>=6){
stock=6;
}
for (var i=1;i<=stock;i++){
//alert ('id: '+id+'; stock: '+stock);
number23.options[number23.options.length]=new Option(i, i);
}
// Alter 'this', which is the clicked element in this case
this.style.backgroundColor = '#000';
}

$(function() {
/*if product_types is a class of element ul the code below
will work otherwise use $('li.product_types') if it's a
class of li elements */
$('.product_types li').click(function() {
//remove this class that causes background change from any other sibling
$('.altBackground').removeClass('altBackground');
//add this class to the clicked element to change background, color etc...
$(this).addClass('altBackground');
});
});
Have your css something like this:
<style type='text/css'>
.altBackground {
background-color:#EE178C;
/* color: your color ;
foo: bar */
}
</style>

Attach a jQuery click event to '#product_types a' that removes a class from the parent of all elements that match that selector; then, add the class that contains the styles you want back to the parent of the element that was just clicked. It's a little heavy handed and can be made more efficient but it works.
I've made an example in jsFiddle: http://jsfiddle.net/jszpila/f6FDF/

try this instead:
//ON PAGE LOAD
$(document).ready(function() {
//SELECT ALL OF THE LIST ITEMS
$('.product_types > li').each(function () {
//FOR EACH OF THE LIST ITEMS BIND A CLICK EVENT
$(this).click(function() {
//GRAB THE CURRENT LIST ITEM, CHANGE IT BG, RESET THE REST
$(this)
.css('background-color','#EE178C')
.siblings()
.css('background-color','transparent');
});
});
});
If I am correct, the problem is that the click event is being binded to all of the list items (li). when one list item is clicked the event is fired on all of the list items.
I added a simple .each() to your code. It will loop through each of the list items and bind a event to each separately.
