I have hide and show functionality on dynamically generated cards after form submission.
{{#each newaction}}
<div class="workflowcard">
<div class="module-card-small">
<div class="res-border"></div>
<div class="card-img">{{team}}</div>
<div class="res-content">
<div class=" newaction-name">{{action_title}}</div><hr>
<div class="newaction-des">{{description}}</div>
<!-- <div class=" due-on">Due on:{{d_date}}</div><hr>-->
</div>
<div class="due">
Due on:
<div>
<div class="day-stamp">{{weekday d_date}}</div>
<div class="date-stamp">{{date d_date}}</div>
<div class="month-stamp">{{month d_date}}</div>
</div>
</div>
{{> actioncardsubcontent}}
</div>
<div class="btn-box">
<button type="button" class="cancelsub">Hide Option</button>
<button type="submit" class="createbtnsub">Show Options</button>
</div>
</div>
</div>
{{/each}}
</div>
</div>
<template name="actioncardsubcontent">
<div class="subcontent" >
<div class="modulepath"><div>{{module_list}}</div></div>
<div class="linkto"><div>Linked To: <div class="linkto-color">{{link}}</div></div></div>
<div class="description"><div>Notes:<br>{{description}}</div></div>
</div>
</template>
When I click on show options button the action card subcontent is displaying and when I click on hide option it is hiding.
The problem is, the hide and show functionality is applying for all the cards which are creating dynamically at a time when I click on single card. I understand the reason is I have given the class name for the buttons. So how to stop that and make it work to current target.
Here is my JS:
Template.actioncardsubcontent.rendered = function(){
this.$(".subcontent").hide();
};
Template.workflow.events({
"click .createbtnsub":function(){
$('.subcontent').show();
},
"click .cancelsub":function(){
$('.subcontent').hide();
}
What you need to do is give a unique ID for each iteration to your cards div class attribute.
in JSTL usually has indexId attribute. You can use that and set your class.
Sample:
{{#each newaction indexId="i"}}
{{/each}}
<div class="btn-box">
<button type="button" class="cancelsub<%=i%>">Hide Option</button>
<button type="submit" class="createbtnsub<%=i%>">Show Options</button>
</div>
In your javascript:
use i to hide.
You have a couple of options here. The one I prefer is to put everything in the {{#each}} into its own template. If you do that, you can put the button click events inside of the child template's event which makes it much simpler to manipulate your data. An example:
Templates:
<template name='workflow'>
{{#each newaction}}
{{> card}}
{{/each}}
</template>
<template name='card'>
<div class="workflowcard">
<div class="module-card-small">
<div class="res-border"></div>
<div class="card-img">{{team}}</div>
<div class="res-content">
<div class=" newaction-name">{{action_title}}</div><hr>
<div class="newaction-des">{{description}}</div>
</div>
<div class="due">
Due on:
<div>
<div class="day-stamp">{{weekday d_date}}</div>
<div class="date-stamp">{{date d_date}}</div>
<div class="month-stamp">{{month d_date}}</div>
</div>
</div>
{{> actioncardsubcontent}}
</div>
<div class="btn-box">
<button type="button" class="cancelsub">Hide Option</button>
<button type="submit" class="createbtnsub">Show Options</button>
</div>
</div>
</div>
</template>
Javascript (template.$ docs):
Template.cards.events({
"click .createbtnsub":function(event, template){
template.$('.subcontent').show();
},
"click .cancelsub":function(event, template){
template.$('.subcontent').hide();
}
});
-- OR --
You can do a better DOM query.
Without more info on what is actually in the actioncardsubcontent template or proper testing, this is a best guess on what you're trying to find. You should be able to tweak this query to meet your specific needs easily enough through trial and error. Please read the jQuery Traversing docs as it should clear this up a bit for you.
Template. workflow.events({
"click .createbtnsub":function(event, template){
$(event.target).siblings('.due').find('.subcontent').show();
},
"click .cancelsub":function(event, template){
$(event.target).siblings('.due').find('.subcontent').hide();
}
});

Im trying addClass to wizard-step when button clicked, but still no luck :/
<div class="mt-4">
<div class="wizard-steps">
<div class="wizard-step">
<div class="wizard-step-icon">
<i class="far fa-user"></i>
</div>
</div>
<form class="wizard-content mt-2" id="regForm">
<fieldset>
<div class="form-group row">
<div class="col-lg-4 col-md-6 text-right">
<button type="button" onclick="step0(this);" class="btn">Next</button>
</div>
</div>
</fieldset>
</form>
</div>
JavaScript:
<script>
function step0(element) {
$(element).prev('div').find('.wizard-step').addClass('wizard-step-active');
}
</script>
Can anyone please help me !
prev is used to retrieve a previous sibling element. The .wizard-step you want to target is a child of a sibling to a parent of the button being clicked. As such you need to use closest() instead.
Also note that onclick (and all the other onX attributes) are not good practice and should be avoided. As you're already using jQuery you can attach your event unobtrusively, like this:
jQuery($ => {
$('.btn').on('click', function() {
$(this).closest('.wizard-steps').find('.wizard-step').addClass('wizard-step-active');
});
});
.wizard-step-active { color: #C00; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mt-4">
<div class="wizard-steps">
<div class="wizard-step">
<div class="wizard-step-icon">
<i class="far fa-user">User icon</i>
</div>
</div>
<form class="wizard-content mt-2" id="regForm">
<fieldset>
<div class="form-group row">
<div class="col-lg-4 col-md-6 text-right">
<button type="button" class="btn">Next</button>
</div>
</div>
</fieldset>
</form>
</div>
Alternatively, instead of calling find() from the shared parent, you could select the form and use prev():
$('.btn').on('click', function() {
$(this).closest('.wizard-content').prev('.wizard-step').addClass('wizard-step-active');
});
Either is fine, it just depends on how your HTML is structured as to which fits best for this use case.
You don't want the div immediately before the button, but the one containing the relevant item(s). So instead of $(element).prev('div') write $('.mt-4').
Your this parameter is referring your button, not your div.
You can do this without Jquery, just using your function like this:
function step0() {
const element = document.getElementsByClassName('wizard-step');
element.classList.add('wizard-step-active');
}
So, you don't need to pass this as a parameter to step0 function.
I want to remove an element using jQuery.
HTML:
<div class="listContainer" id="listContainer">
<div class="listItem">
<div class="name">
Item Name
</div>
<div class="amount">
<input type="text" class="amountInput" />
</div>
<div class="delete">
<div class="deleteBtn">
X
</div>
</div>
</div>
</div>
There are several listItemss on the page and each of the listItem will be created dynamically using jQuery. I want to delete amountInput of specific listItem by clicking the deleteBtn, so I tried doing:
$("#listContainer").on("click", ".deleteBtn", function() {
$(this).closest(".amountInput").remove();
});
This doesn't work. But on the other hand if I try to delete a listItem as a whole, the code works:
$("#listContainer").on("click", ".deleteBtn", function() {
$(this).closest(".listItem").remove();
});
Why is this happening?
Thanks.
Because .closest propagates to the top of the HTML. So it searches for the first parent that matches your selector. That is why it cannot find .amountInput. Because it isn't a parent of your button.
To get .amountInput you have to:
$("#listContainer").on("click", ".deleteBtn", function() {
$(this).closest(".listItem").find('.amountInput').remove();
});
This will get the wrapping .listItem element and then search it for the .amountInput element.
Your selector is not correct, use find instead of closest could be helpful in this case, also $(this) in your sample is related to deleteBtn class not to listContainer.
$("#listContainer").on("click", ".deleteBtn", function() {
console.log($(this)) // this here is .deleteBtn not listContainer
$(this).closest(".listItem").find(".amountInput").remove();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="listContainer" id="listContainer">
<div class="listItem">
<div class="name">

</div>
<div class="amount">
<input type="text" class="amountInput" />
</div>
<div class="delete">
<div class="deleteBtn">

What if it has few parents? (as in grandparents, great grandparents)
<div class="lvl1">
<div class="lvl1.1">
<div class="lvl1.2">
<button class="btn-submit">Click Me</button>
<div class="a1">Hello
<div>
</div>
</div>
<div class="lvl2">
<div class="b1">
<div class="b2">Make me disappear!</div>
</div>
</div>
<div class="lvl3">
<div class="c1">Thank you.
</div>
</div>
JS
$(function(){
$(".btn-submit").click(function() {
$(this).parent(".lvl1").siblings(".lvl2").children(".b2").hide();
});
});
How to use .parent, .parents, .siblings, .children, .next, .prev to show and hide the div?
If I assume that you have that structure repeated and want to remove the one in the same copy as the .btn_submit that was clicked, we go up to the .lvl1 via closest, over to the .lvl2 via .nextAll().first() (or we could just use .next), and then .find the .b2 in there:
$(".btn-submit").click(function() {
$(this).closest(".lvl1").nextAll(".lvl2").first().find(".b2").hide();
});
Your code is very close, just two things that I had to change:
Instead of using .siblings(".lvl2"), which will find all of them, I used .nextAll(".lvl2").first() to just find the one immediately after "this" .lvl1.
I used find instead of children, because children will only go down one level (direct child), not search descendants
I also used closest(".lvl1") so that if you move the .btn_submit deeper into .lvl1, it will continue working.
Live Example:
$(function() {
$(".btn-submit").click(function() {
$(this)
.closest(".lvl1")
.nextAll(".lvl2")
.first()
.find(".b2")
.hide();
});
});
<div class="lvl1">
<button class="btn-submit">Click Me</button>
<div class="a1">Hello
</div>
</div>
<div class="lvl2">
<div class="b1">
<div class="b2">Make me disappear!</div>
</div>
</div>
<div class="lvl3">
<div class="c1">Thank you.
</div>
</div>
<div class="lvl1">
<button class="btn-submit">Click Me</button>
<div class="a1">Hello
</div>
</div>
<div class="lvl2">
<div class="b1">
<div class="b2">Make me disappear!</div>
</div>
</div>
<div class="lvl3">
<div class="c1">Thank you.
</div>
</div>
<div class="lvl1">
<button class="btn-submit">Click Me</button>
<div class="a1">Hello
</div>
</div>
<div class="lvl2">
<div class="b1">
<div class="b2">Make me disappear!</div>
</div>
</div>
<div class="lvl3">
<div class="c1">Thank you.
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
there is possible to disappear div directly using,
$(".b2").hide();
but if you want to use ".parent, .parents, .siblings, .children, .next, .prev",
$(".btn-submit").parent().siblings(".lvl2").children().children(".b2").hide();
need to you children() Two times... because .b2 is not directly child to .lvl2,
another best way to hide ".b2" is,
$(".btn-submit").parent().siblings(".lvl2").find(".b2").hide();
so your Ans is:
$(".btn-submit").click(function() {
$(".btn-submit").parent().siblings(".lvl2").find(".b2").hide();
});
.children selects the children and not descendants of the element. You just need to replace the .children with the .find method and your code will select the target element.
A webpage with HTML looks like this:
<div id="Parent-div" > </div>
<div class="first-child-div"> </div>
<div class=" second-child-div">
<div class="first-grand-child"> </div>
<div class="second-grand-child"> </div>
<div class="Third-grand-child">
<div class="Grand-grand child">
<button class="Confirm-button">Confirm!</button>
</div>
</div>
</div>
I've Tried This code using greasemonkey to remove
a button from the div with the class named "Grand-grand child"
This is what I did:
var targetDiv = document.querySelector("#<Parent-div>. Grand-grand.child");
targetDiv.innerHTML = "Hello world!";
The Button wasn't replaced by the Hello world! text, What did I do wrong?
document.querySelector('.Grand.grand.child');
Demo: http://jsfiddle.net/yGv3v/
You should change <div class=" Grand grand child"> to <div class="Grand-grand-child"> and then you can select it with $('.Grand-grand-child').
Edit
If you want to use pure JavaScript, then you can select the node element via
var grandChildChildNode = document.getElementsByClassName('Third')[0].children[0]
This should work in sufficiently modern browsers.
I have this HTML code:
<div id="content">
<div class="profile_photo">
<img style="float:left;margin-right:7px;" src="http://gravatar.com/avatar/53566ac91a169b353a78b329bdd35c95?s=50&d=identicon" class="profile_img" alt="{username}"/>
</div>
<div class="container" id="status-#">
<div class="message">
<span class="username">{username} Debugr Rocks!
</div>
<div class="info">24-oct-2010, 14:05 GMT · Comment (5) · Flag · Via Twitter
</div>
<div class="comment_container">
<div class="profile_photo">
<img style="float:left;margin-right:7px;" src="http://gravatar.com/avatar/53566ac91a169b353a78b329bdd35c95?s=32&d=identicon" class="profile_img" alt="{username}"/>
</div>
<div class="comment_message">
<span class="username">{username}</span> Debugr Rocks! XD
</div>
<div class="comment_info">24-oct-2010</div>
</div>
</div>
<div class="profile_photo">
<img style="float:left;margin-right:7px;" src="http://gravatar.com/avatar/53566ac91a169b353a78b329bdd35c95?s=50&d=identicon" class="profile_img" alt="{username}"/>
</div>
That is repeated two or more times. What I want to do, is to when I click the "Comments (5)" link, the class "comment_container" appears, but only the one in the same "container" class.
It's this possible?
You can use .closest() to go up to the .container then .find() to look inside it, like this:
$(".toggle_comment").click(function() {
$(this).closest(".container").find(".comment_container").show();
});
You can try it here, if you're curious about finding other things relative to this here's a full list of the Tree Traversal functions.
As an aside, there's an error in your HTML that needs correcting, this:
<span class="username">{username} Debugr Rocks! </div>
Should be:
<span class="username">{username} Debugr Rocks! </span>
