When I type
console.log(document.getElementById('kitHeight').offsetHeight);
It prints 30 on the console, which is wrong.
But, when I type the same using developer console, it gives me 65, this is correct.
The height of the div is 65px.
Kindly help me why this behaves like it does and how to get 65px as the correct answer using javascript
#CBroe already told you that the information you are offering is too little to help you.
But it might be the case, that you are trying to run the script before the DOM actually rendered the div. See this example:
<script>
console.log(document.getElementById("class").offsetHeight);
//Errors
</script>
<div id="class"></div>
<script>
console.log(document.getElementById("class").offsetHeight);
//Returns: 0
</script>
<script>
const i = document.getElementById("class");
i.innerHTML = "John Doe";
console.log(document.getElementById("class").offsetHeight);
//Return: 19
</script>
The second and third pieces of code will return the height. The first one will error because the div is not in the DOM yet. The third one will return an updated size from dynamic content.

I've been working on a project and I have everything functional on the page, minus one little set back. When I open the edit profile form there is 28 blank spaces before the name and title, while there is also 24 spaces after. If I delete all the text and spaces then my placeholder text will appear in the correct spot. My add element popup works with no issues. I have been combing over my code to see if I have any extra spaces that could be doing this and I still can't find anything. Any help would be appreciated.

The issue is in your javascript file index.js
editButton.addEventListener("click", () => {
if (!editProfileModalWindow.classList.contains("popup_is")) {
nameInput.value = profileName.textContent;
aboutInput.value = profileSubname.textContent;
}
toggleModalWindow(editProfileModalWindow);
})
The textContent property gets the content of all elements, not just the text (see more here). Because your element has a <h1> element child, you are getting the extra space.
To fix this, you can either:
Use the innerText property instead of textContent which only gets the human readable text
Make the profileName variable refer to the h1 element rather than it's parent. Then textContent will work properly
Examples:
editButton.addEventListener("click", () => {
if (!editProfileModalWindow.classList.contains("popup_is")) {
nameInput.value = profileName.innerText;
// or
// nameInput.value = profileName.children[0].textContent
aboutInput.value = profileSubname.innerText;
}
toggleModalWindow(editProfileModalWindow);
})

So I have a 'form search' function script that I am trying to apply to items within a container. I have found this from a tutorial online that someone used to search members of teaching staff. only I am looking to apply this to my div classes:
$('.form-search').on('submit',function(){return false;});
$('.form-search .btn').on('click', function(e){
var query = $.trim($(this).prevAll('.search-query').val()).toLowerCase();
$('div.dress-container .bold').each(function(){
var $this = $(this);
if($this.text().toLowerCase().indexOf(query) === -1)
$this.closest('div.dress-container').fadeOut();
else $this.closest('div.dress-container').fadeIn();
});
});
Here is the jsfiddle - I was trying to pull the image and text using the JS and class but it would not work:
http://jsfiddle.net/lmac1/x6kv91qk/
Can anyone point me in the right direction? I was using this JQuery hide all divs except for the divs I search for
The problem is that your <div class="dress-container"> is currently wrapping all of your products, therefore you keep on hiding all of them once you use the searchbar.
I fixed your html markup here and removed the <div class="row"> so they line up nicely when you have filtered them:

I am building an expandable grid portfolio but the styles for the .showcase <a> tag and <p> tag are not showing up. I am not sure why. I think it has something to do with .html() not grabbing the <a> and <p> selector but just the content inside it. Though this does not happen to the <img> tag. I am a little baffled. Here is my jsfiddle
http://jsfiddle.net/theMugician/L2xyatfd/38/
Hey everyone I figured out what my problem was. I was calling html() twice which makes a lot of sense now. In the variables $aTag and $html I didn't need to call the html() because I was going to call it again in the .showcase div.
var $aTag = $a.eq($item.data('rel'));
var $html = $p.eq($item.data('rel'));
<!---.showcase div--->
$link.html($aTag).show(0);
$details.html($picture).show(0);
Here is the new fiddle
http://jsfiddle.net/theMugician/L2xyatfd/47/
Simply try :
var $aTag = $a.eq($item.data('rel'));
var $html = $p.eq($item.data('rel'));
$link.append($aTag).show(0);
$images.append($picture).show(0);
It will wrap the element, not just its html content

I have a div which is like this:
<div id="mainDiv">
<script>
javascript here...
</script>
</div>
I basically want to get the ID of the div it is inside.
I have tried using jQuery and classic javascript to do this but it keeps returning undefined.
Does anyone have any idea's? Thanks
Since broswer read the code from up to down, you can do this:
Vanilla JS
var scriptTags = document.getElementsByTagName('script');
var id = scriptTags[scriptTags.length - 1].parentNode.id;
jQuery
var id = $('script').last().parent().prop('id');
when it will read this code, the last script tag is the one the browser is reading.
Here's a fiddle : http://jsfiddle.net/nb234/
Check this out http://jsfiddle.net/78N9A/1/
<div id="parent">
<script id="scr">
function show()
{
alert('hello');
}
</script>
</div>
window.onload = function(){
var ele = document.getElementById('scr').parentNode;
alert(ele.id);
}
<script id="script">
Then
$('#script').parent();
If I understand correctly, you are saying that the id on the parent div is unknown in advance, and you want to use JS to determine what it is.
If you can't edit the script tag to add an id, maybe you could do a document.write() within that block to add in a little hidden element, then you can test to see what that element's parent is.
http://jsfiddle.net/AtRYF/
JAVASCRIPT:
Give your script an ID and then use parentNode to move up the DOM.
var the_div_you_want = document.getElementById("skript").parentNode.id;
JQUERY:
Pretty sure .parent() is what you're after
$('#scriptId').parent().attr("id");
Regardless, you need to find some way to locate the script and the move up the dom to find that relationship. Hope this helps.
http://jsfiddle.net/Zbuf8/1/
jQuery(document).ready(function($) {
$('div').attr('id');
});
should get you the value you need.

I've this function in my script :
$("#image4").click(function(){
if($(this).attr("src")=="http://XXX.jpg"){
$(this).attr("src","http://YYYY.jpg");
}else{
$(this).attr("src","http://XXX.jpg");
}
return false;});
HTML
<img src="http://XXX.jpg" id="image4"/>
I don't understand why when I click on my image, the if part doesn't works. I explain : If I use this code, nothing change. If I add and alert un my click function, I see the alert twice and see the image change twice to.
It seems, "if" doesn't works and apply "if" and "else" at each time
Someone can help me about that. I think it a basic feature, I don't understand why it doesn't works.
Thanks
("#image4").click(function(){
^^
you missed a bracket!
Working: http://jsfiddle.net/MAVyb/
The sysntax and everything on your code is right so it is definetly value problem. Problem may be src have leading or trailing space in it.
try alert like
alert("-"+$(this).attr("src")+"-")
and whether is there any space between -(hypen) and src value.
also try
alert(($(this).attr("src")=="http://XXX.jpg")), it should return true if the src is equal
Update: i can reproduce your problem -- you should have attached the event listener function for two times. check your original code. that is the problem. check your code. you can verify this by changing id to some other in jquery method and img tag
