I'm about lose my mind with this problem. No form of jQuery selector seems to work in dynamically finding any elements above the link. I'm trying to access an element above the link and hide it. Using things like parent(), prev(), before(), closest(), ect. will show a non-null object but it won't respond to the hide() method.
<div class="row">
<div class="col-xs-5">
<div id="test_fields">
<li id="test_input" class="string input optional stringish">
<label class="label" for="test_input">Ingredient name</label>
<input type="text" name="test_input" value="afsfasf" id="test_input">
</li>
</div>
<input type="hidden" id="recipe_recipe_ingredients_attributes_0__destroy" name="recipe[recipe_ingredients_attributes][0][_destroy]">
Remove Ingredient
</div>
</div>
function remove_fields(link)
{
$(link).prev("input[type=hidden]").val('1'); // this doesn't work
var divToHide = $(link).prev('div');
$(divToHide).hide() // this doesn't work
//$('#test_fields').hide(); //this works
}
Try replacing the link as below:
Remove Ingredient
I'm not sure. But maybe this is the problem. Because I remember that I have had problem with 'this'previously and when I replaced that, it performed the job.
you can try .closest() and .find()
function remove_fields(link) {
$(link).closest('div[class^="col-xs"]').find("input[type=hidden]").val('1');
var div_to_hide = $(link).closest('div[class^="col-xs"]').find('#test_fields');
$(div_to_hide).hide();
//$('#test_fields').hide(); //this works
}
You can't change hidden input's "value" attribute by using .val(). You need to use:
$(link).prev("input[type=hidden]").attr('value', '1');
As I'm not really sure what do you want to do with this input, I'll just let it go like this.
.prev() fn goes only one previous element in the structure. As input is a <a>'s previous element, you can't select div like that. You can use .siblings() for instance.
$(link).siblings('div').hide();
If you break the code in pieces, it gets easier.
First I took the 'Link', from it I grabbed the nearest div above it, then I picked up the input.
I did not make many changes to your code.
function remove_fields(link)
{
var $link =$(link);
var $divToHide = $link.closest('div');
$divToHide.find("input[type='hidden']").val('1');
$divToHide.hide()
}

I want to create a dynamic form where I also apply JavaScript to the dynamic elements.
What I want to do right now is figure out which field (stored in array or whatever data structure) in JavaScript has been clicked so that I can apply the script to that particular field.
The HTML looks like this:
<div class="triple">
<div class="sub-triple">
<label>Category</label>
<input type="text" name="category" id="category" placeholder="Classes/Instances" required/>
<ul class="cat-list"></ul>
</div>
<div class="sub-triple">
<label>Relation</label>
<input type="text" name="relation" id="relation" placeholder="Properties" required/>
<ul class="rel-list"></ul>
</div>
<div class="sub-triple">
<label>Value</label>
<input type="text" name="value" id="value" placeholder="Classes/Instances" required/>
<ul class="val-list"></ul>
</div>
</div>
This "triple" div is dynamic and I want to create as many "triples" as the user wants, that also means the input fields of inside the "triple" section increase as well.
I'm confused on how to add javascript to one element of the input. For example I have inputs: category, relation and value and the user wanted 2 or more triples then the input ids could look like category2, relation2 and value2 or something similar to that.
let category = document.getElementById("category");
category.addEventListener("keyup", (e) => {
removeElements();
listDown(category, sortedClasses, ".cat-list")
});
If I lets say clicked on category2 for instance how do I tell that to my javascript since these fields are completely dynamic.
Summary: The user is adding repeat sections of triples (containing 3 input elements), where the id of each input element is generated dynamically. My script above works for the first triple section only as the ids are fixed, as for successive "triple" section the id of the fields get changed. How do I identify (see which element has been clicked) and get these dynamic ids
Try listening to the parent element and then using the event's target to figure out the identity of the input. Since the child elements events will bubble up you'll be able to listen to all children
e.g.
let parentElement = document.querySelector(".triple");
parentElement.addEventListener("click", (e) => {
console.log(e.target.id);
});
You can use the onfocus event
<div class="triple">
<div class="sub-triple">
<label>Category</label>
<input type="text" name="category" id="category" placeholder="Classes/Instances" onfocus="onFocusCategoryInput()" required/>
<ul class="cat-list"></ul>
</div>
<div class="sub-triple">
<label>Relation</label>
<input type="text" name="relation" id="relation" placeholder="Properties" onfocus="onFocusRelationInput()" required/>
<ul class="rel-list"></ul>
</div>
<div class="sub-triple">
<label>Value</label>
<input type="text" name="value" id="value" placeholder="Classes/Instances" onfocus="onFocusValueInput()" required/>
<ul class="val-list"></ul>
</div>
</div>
I try to change a text insert in an div box with jquery. Here is the Code:
<div onClick="$(this span).text('My new Text');" class="switch switch-success" style="float: right;">
<label>
<input type="checkbox"><span>Yes</span>
</label>
</div>
I want to change this "Yes" to "No". Thanks for help ;)
Use the .find method
See a working fiddle here
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div onClick="$(this).find('span').text('My new Text');" class="switch switch-success" style="float: right;">
<label>
<input type="checkbox"><span>Yes</span>
</label>
</div>
You have two options.
Pass this a second parameter which is context
$('span', this).text('My new Text');
Get this element and that use find to get span in it.
$(this).find('span').text('My new Text');
Please separate structure, style and function - the CSS, HTML and JS should not be in the same space - its always better to separate the code for better code quality.Also you could do a toggle for the states of the checkbox so that there is different text on the "checked" and "not checked" states.
And you can even do that with CSS
$('.switch').click(function(){
$(this).find('span').text('My new Text')
})
.switch{float: right}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="switch switch-success" >
<label>
<input type="checkbox"><span>Yes</span>
</label>
</div>
This is my code:
Javascript:
$(".test").on("focusout", function (e) {
$("#output").append("Lost focus<br>");
});
HTML:
Inputs inside div:
<div class="test">
<input type="text" />
<input type="text" />
</div><br>
Inputs outside div:<br>
<input type="text" />
<div id="output">
</div>
I want to detect if user leaves "div.test". Unfortunately, "focusout" works also when I move focus to other object inside this div.
Look at this fiddle: http://jsfiddle.net/Piotrek1/wfukje3g/6/
Click on first input and use Tab to switch through textboxes. "
Lost focus" should appear only if user move out from the div, but it happens always. Why is that and how to change it?
The $ operator returns a collection. You have two inputs inside the <div class="test">. So it matches all elements and children with the .test class.
I think what you want two divs with separate input elements and two different classes OR, use an ID on the actual input element so the $ operator only matches the input id you want this event to fire on. http://jsfiddle.net/wfukje3g/7/
$("#test").on("focusout", function (e) {
$("#output").append("Lost focus<br>");
});
<div class="sometest">
<input id="test" type="text" />
<input type="text" />
</div><br>
Inputs outside div:<br>
<input type="text" />
<div id="output">
</div>
I have implemented piece of code to handle div focus out
$(document).ready(function () {
var count = 1;
$("#name").focusout(function (e) {
if($(this).has(e.relatedTarget).length === 0) {
$("#output").append("<label style='width:100%;'>"+ count++ +" Name div focus out </label>");
}
});
});
Inputs inside div:
<div id="name" class="test">
<input type="text" id="firstname"/>
<input type="text" id="lastname"/>
</div>
Inputs outside div:<br>
<input type="text" id="dob"/>
<div id="output" style="width:100%"></div>
In this piece of code I have used relatedTarget.
relatedTarget will provide the next focused element If next element is not the child of this div then it is div focus out.
Try this in your code.
I hope this will be helpful.
Thanks

I got this snippet of code and I would like to replace the "ARRIVAL" text which is between the top and lower level <div> element but I can't figure out a way.
I don't want to use replaceWith , html or similar methods on <div class="left booktext"> because that would replace the rest of html elements. There is an event handler attached to input class="bookfields" and I don't want to lose that. Unfortunately, there is no event delegation.
<div class="left booktext">
ARRIVAL
<div class="bookborder">
<input type="hidden" name="checkin" value="2014-03-05">
<input type="text" class="bookfields hasDatepicker" style="width:65px;" id="checkin-select" placeholder="dd/mm/yyyy">
</div>
</div>
You can use contents() along with replaceWith():
$('.left').contents().first().replaceWith("New Text");
Fiddle Demo
In pure Javascript:
var books = document.querySelectorAll('.booktext');
for (var i = 0, length = books.length; i < length; i++) {
books[i].firstChild.data = "your text";
}
Easier with jQuery though:
$('.booktext').contents().first().replaceWith("your text");
Advice
Is better put text in a span element, with all the benefits of the case.
In this way you can put your text in any order inside div, like:
<div class="left booktext">
<div class="bookborder">
<input type="hidden" name="checkin" value="2014-03-05">
<span>ARRIVAL</span>
<input type="text">
</div>
</div>
And than replace with:
$('.bookborder span').text('my new text');
In pure javascript you can access a text node like this
var bookText = document.querySelector(".booktext");
bookText.firstChild.nodeValue = "Some other text";

When I click .getdata, I want to go from .getdata to name=top and read the value of whichever option is selected (in this case it's 0), but I'm having a hard time getting to it. I keep getting undefined.
This is my html. The div class="main" repeats so I can't simply select input[name=top]. It would have to be through traversing the tree to the closest input[name=top]. Can someone get this right? I'm starting to think it's a browser error because I tried different options and all give me undefined.
<div class="main">
<div class="branch">
<div class="element">
<label>top color:</label>
<input type="radio" value="1" name="top">black
<input type="radio" value="0" name="top" checked="checked">white
<input type="radio" value="null" name="top">transparent
</div>
</div>
<div class="controls">
<a class="getdata">get data</a>
</div>
</div>
<div class="main">
....
</div>
$('a.getdata').click(function() {
var val = $(this).closest('.main').find('input[name="top"]:checked').val();
});
Place a click()(docs) event on the <a> element
On a click, use the closest()(docs) method to traverse up to the .main element
Then use the find()(docs) method along with the the attribute-equals-selector(docs) and the checked-selector(docs) to get the checked name="top" radio.
Finally use the val()(docs) method to get its value.
$(".getdata").click(function(){
selectedValue=$(this).parent().prev().children().children("input[name=top]:checked").val();
console.log(selectedValue);
});
