slide hidden div on an onclick event

I have the following php while loop code:
while (...($...)){
$convid = $row['ID'];
echo"
<button onclick='getconvo($convid)'>open</button>
<div class="convowrap"></div>
";
}
and the javascript code
<script type='text/javascript'>
$(document).ready(function(){
$(".convowrap").hide(0)
})
</script>
script type='text/javascript'>
function getconvo(id){
$(".convowrap").hide(0).delay(200).slideDown(500)
var convid = id;
$('.convowrap').load('fetch_info.php', {id : convid}, function () {
// do something when success
});
}
</script>
When i click on the button above that says 'open,' all of the div that says convowrap slides, but i only want the current div to slide based on the button that was clicked that was generated from the php while loop.
If the php loop executed three times, when i click on the first button generated by the first loop, the convowrap div slides on all three entries generated by the loop.
What do I do? Please help?
Thanks in advance.

The problem is that all the divs have the same class so its functioning as you it is supposed to ...
As you have the div after the button you can replace
$(".convowrap")
With
$(this).next()
Inside the function for both .load and .hide
(Whichever you want)
more generic
It may be more usefull to assign another class to each div like
<div class='convowrap dummyclass$convid'></div>
And on button click change the selector to match that class like
$('dummyclass'+id)
Hope this helps

As you are using inline onlclick function inside HTML, you have to pass this explicitly like onclick='getconvo(this)'.
Anyway, see the following fiddle and hope you wanted this workaround -
https://jsfiddle.net/nuhil/4scas2gh/
Code:
<button onclick='getconvo(this)' id="1">Button 1</button>
<div class="convowrap">Content First</div>
<br/>
<button onclick='getconvo(this)' id="2">Button 2</button>
<div class="convowrap">Content Second</div>
<!-- More pairs of (button and div) go here -->
<script>
$(document).ready(function(){
$(".convowrap").hide();
})
function getconvo(button){
$(button).next().delay(200).slideDown(500);
// You could use toggle here like following for better UX
// $(button).next().toggle("slow");
// Anyway,
// Get the id from button attribute but make sure you already set it by PHP
var convid = $(button).attr("id");
console.log(convid);
// $(button).next().load('fetch_info.php', {id : convid}, function () {
// do something when success
// });
}
</script>

how to Javascript toggle ID of div generated on runtime

I am sending a Model to a View in MVC,
and for each "Person" in my Model, I want to create a button that says "Show Details", when the user clicks it, a div with more information about that person toggles.
I am generating a a href and div id assigned to each person ID like the following:
foreach (var person in Model.Persons)
{
<div>
Show Details
</div>
<div id="#Html.Raw("detailsDiv-" + #person.id)">
<!--Content Here -->
</div>
}
I want to create the javascript that toggles on a click event
So I want to write this script but with the unique id for each person:
I want to get the id of the div that needs to be toggled.
I tried writing the script inside the foreach loop so I can be able to read the #person.id value, but it didnt work:
<script>
$(document).ready(function () {
$("#showDetails-#person.id").click(function () {
$("#details-#person.id").toggle();
});
});
</script>
Can anyone help?

put a class to your links like class="showDetails".
Now you Can create a global Event for all that links:
$('.showDetails').click(function(e) {
var id = this.id // extract id.. split with '-' or whatever..
$('#details-' + id).toggle();
});

you could put the id in a tag like "person_id" and use a class to trigger the jquery event.
<div class="middle_right">
<a class="showDetails" href="#" person_id="#Html.Raw("showDetails-" + #person.id)">Show Details</a>
</div>
and in js
$(".showDetails").click(function () {
var person_id=$(this).attr("person_id")
});

jQuery display property not changing but other properties are

I'm trying to make a text editable on clicking it. Below is the code I'm trying. When the title is clicked it shows an input box and button to save it.
<div class="block">
<div class="title">Title</div>
<div class="title-edit">
<input type="text" name="title" value="Title">
<button>Save</button>
</div>
</div>
I have changed other properties like color or changing the text of the elements and its working, but it is not applying the display property or .show()/.hide() function on the title or edit elements.
Below is my jQuery
$(function(){
$('.block').on('click', editTitle);
$('.title-edit button').on('click', saveTitle);
});
function saveTitle(){
var parent = $(this).closest('.block');
var title = $('.title', parent);
var edit = $('.title-edit', parent);
$(title).show();
$(edit).hide();
}
function editTitle(){
$('.title-edit', this).show();
$('.title', this).hide();
}
Here's the jsfiddle
https://jsfiddle.net/ywezpag7/
I've added
$(title).html('abcd');
to the end to show that other properties/functions are working, but just not the display.
For checking the html change on title element you will have to check the source through developer tools cause the title element is hidden.
Where am I going wrong?

Your problem is in the function saveTitle. The first line must stop the event propagation otherwise after this function the editTitle function is called.
The snippet:
$(function(){
$('.block').on('click', editTitle);
$('.title-edit button').on('click', saveTitle);
});
function saveTitle(e){
// this line
e.stopPropagation();
var parent = $(this).closest('.block');
var title = $('.title', parent);
var edit = $('.title-edit', parent);
title.show();
edit.hide();
title.text($('.title-edit input').val());
}
function editTitle(e){
$('.title-edit', this).show();
$('.title', this).hide();
}
.title-edit{
display:none
}
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<div class="block">
<div class="title">Title</div>
<div class="title-edit">
<input type="text" name="title" value="Title">
<button>Save</button>
</div>
</div>

The issue as mentioned already is that your click events are fighting. In your code, the title-edit class is within the block, so when you click on the save button it triggers events for both clicks.
The easiest and, imho, cleanest way to resolve this is to switch your click event to be called on .title, and .title-edit button. You can also simplify the code beyond what you've got there.
$(function(){
$('.title').click(editTitle);
$('.title-edit button').click(saveTitle);
});
function saveTitle(){
$('.title').show();
$('.title-edit').hide();
$(title).html('abcd');
}
function editTitle(){
$('.title-edit').show();
$('.title').hide();
}

I tried debug your code, and I had seen, that then you click to "Save" button, handled both functions, saveTitle() and editTitle(), and in that order. Therefore, the elements initially hidden, and then shown.

Toggling Background Color on Click with Javascript

I am working on a class project and need to be able to toggle the background color of a transparent png on click. I have been working through a number of examples from the site, but I can't get it working. I am a total novice at Javascript and haven't had luck trying to plug in jQuery code either.
Here is the targeted section:
<div class="expenseIcon"><a href="#">
<img src="images/mortgage.png"></a><br/>
<p>Rent or Mortgage</p>
</div>
On clicking the linked image, the goal is for the background on the image to change to green. Clicking it again would change it back to the default, white. Here's the CSS I'd like to toggle on/off with click.
.colorToggle {
background: #A6D785;
}
I had tried adding class="iconLink" to the href and class="iconBox" to the image with the following Javascript adapted from another post, but it didn't work.
var obj = {};
$(document).ready(function () {
$(".iconLink").click(function () {
var text = $(this).find(".iconBox");
obj.var1 = text;
//alert(obj.var1);
//return false;
$('.iconBox').removeClass('colorToggle');
$(this).addClass('colorToggle')
});
});
Any advice would be greatly appreciated!

Let's break down what is happening with your current code when you click the link.
var obj = {};
$(document).ready(function () {
$(".iconLink").click(function () {
var text = $(this).find(".iconBox");
obj.var1 = text;
$('.iconBox').removeClass('colorToggle');
$(this).addClass('colorToggle')
});
});
JQuery finds all elements with the classname "iconBox". In your case, this is the img element. The reference to that element is then saved in "obj.var1". You do not end up doing anything with this reference, so these two lines can be removed.
All elements with the class "iconBox" have the class "colorToggle" removed. Your img element didn't have this class on it, so nothing happens.
The class "colorToggle" is added to the anchor element. Yes! Now the element wrapping the img has a background color.
Unfortunately, clicking the anchor tag again won't do anything, since the anchor tag will already have the "colorToggle" class and all we would be doing would be trying to add it again. Hmm. Let's try changing addClass to toggleClass. Here's our new code:
$(document).ready(function () {
$(".iconLink").click(function () {
$(this).toggleClass('colorToggle');
}
});
Also, note that because we're working with the anchor element, the p element won't be affected by this change. If you want the entire div to change background colors, use this line instead:
$(".expenseIcon").toggleClass('colorToggle');

Using the given markup:
<!-- to toggle the bg-color onClick of anchor tag -->
<div class="expenseIcon">
<a href="#">
<img src="images/mortgage.png">
</a>
<br/>
<p>Rent or Mortgage</p>
</div>
since the question asks for javascript, heres an option for updating the background-color of an element using the built-in js.style method
//get a handle on the link
//only one element w/ className 'expenseIcon'
//first child of 'expenseIcon' is the anchor tag
var link = document.getElementsByClassName('expenseIcon')[0].children[0];
//get a handle on the image
var image = link.children[0];
//listen for click on link & call bgUpdate()
link.addEventListener('click', bgUpdate, false);
function bgUpdate() {
if(image.style.backgroundColor === 'lightgoldenrodyellow'){
image.style.backgroundColor = 'aliceblue';
} else if (image.style.backgroundColor === 'aliceblue') {
image.style.backgroundColor = 'lightgoldenrodyellow';
}
else console.log('image bgColor: ' + image.style.backgroundColor);
}
a similar example

css
.expenseIcon{
background: red;
}
.colorToggle {
background: blue;
}
jquery
$(".expenseIcon").click(function () {
$('.expenseIcon').toggleClass('colorToggle');
});
By default, the div will have expenseIcon background. ToggleClass will toggle the div class with colorToggle so will override the previous color.
You don't need an hyperlink tag A to manage clicks, just put it on the DIV.

remove onclick when attached to children

I have the following code:
layoutOverlaysBldg = $("#layout-overlays-bldg")
layoutOverlaysBldg.on("click", "div", function(event) {
var floor;
console.log("floornum: " + this.dataset.floornum);
floor = parseInt(this.dataset.floornum);
...
$("#choose-floor").fadeOut();
$("#choose-apt").fadeIn();
});
later - based on data I'm getting back from the DB - I want to remove some of the .on("click", "div", ...) from only some of the divs. I already have the selector that is getting the right divs but I cannot figure out how to remove the click event. I have tried .off("click") after selecting the right div but it has no effect.

This issue here is because you are using a delegated event. You can add or remove the event for all child elements, but not individual ones given your div selector.
With that in mind the easiest way to do what you need is to add the event based on a class, then add and remove that class on the children as needed. Something like this:
layoutOverlaysBldg = $("#layout-overlays-bldg")
layoutOverlaysBldg.on("click", "div.clickable", function(event) {
// your code...
});
You can then enable/disable the event on the child div by adding or removing the .clickable class.

You can try like this :
Example :
<div id="test">
<div id="first">first</div>
<div id="second">second</div>
</div>
<div onclick="unbindSecondDiv();">UNBIND</div>
<script>
function unbindSecondDiv()
{
test = $("#second")
test.unbind("click");
alert('Selected Area Click is Unbind');
}
$(document).ready(function(){
//BIND SELECTED DIV CLICK EVENT
test = $("#test > div")
test.bind("click" , function(event) {
alert($(this).attr('id'));
});
});
</script>
In the above example , selected DIV elements click event is bind.
And after execute function unbindSecondDiv() , second DIV click event will be unbind.
Have a try , may helps you.
