I have structure like this. On button click jquery code make border of input red if field is empty. Everything works fine with first row. At others row border become red after button click even if i put valid value.
$('.btn-submit').click(function(){
var value = $(':input').val();
if(!value.length) {
$(this).parents('.row').find(':input').css('border-color','#f00');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='row'>
<input>
<button class='btn-submit'>Check</button>
</div>
<div class='row'>
<input>
<button class='btn-submit'>Check</button>
</div>
<div class='row'>
<input>
<button class='btn-submit'>Check</button>
</div>
Change you JS-Code:
$('.btn-submit').click(function(){
var value = $(this).parent().find('input').val();
if(!value.length) {
$(this).parents('.row').find(':input').css('border-color','#f00');
}
});
Your Issue:
You select all <inputs/> instead of the closest.
When any button is clicked, it is checking the value of the first <input>.
Change this line:
var value = $(':input').val();
To this:
var value = $(this).prev(":input").val();
This should select the <input> element directly before the button.
Another tip: You seem to try to find the child input of the parent using jQuery. Instead, you can find the sibling, using something like prev() (which will work in your case).
Try this:
$('.btn-submit').click(function(){
var value = $(this).parent().find("input").val();
if(!value.length) {
$(this).parent().find(':input').css('border-color','#f00');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class='row'>
<input>
<button class='btn-submit'></button>
</div>
<div class='row'>
<input>
<button class='btn-submit'></button>
</div>
<div class='row'>
<input>
<button class='btn-submit'></button>
</div>
Your problem is that you are looking at all the inputs not just the sibling of the button.
Try this javascript instead:
$('.btn-submit').click(function(){
var value = $(this).parent().find('input').val();
if(!value.length) {
$(this).parents('.row').find(':input').css('border-color','#f00');
}
});

Is there a way to get the value from a div element to textbox?
My script codes
$(document).ready(function() {
barcode.setHandler(function(barcode) {
$('#result').html(barcode);
});
barcode.init();
I show the result with the following code
<div id="result"></div>
I fail to get the div value into the textBox.
<input type="text" id="result">
To achieve expected result, use below option
Avoid using same id for multiple elements , instead of that use class or two different ids or use one as class and for other use as id
$(document).ready(function() {
console.log( $('#result').text())
$('.result').val( $('#result').text());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="result">1222</div>
<input type="text" class="result">
code sample - https://codepen.io/nagasai/pen/yjomXp
Ids need to be unique on a given page; your input and div both have the same id. To insert from the div to the input, first get the text inside the div, then apply that to the input using .val().
const foo = $('#foo').text();
$('#bar').val(foo);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="foo">
This is inside the div
</div>
<input type="text" id="bar"></input>
I wanted to copy the texts when the copy button is clicked. But, it copies the last(3rd) paragraph text when pressing any of the three buttons. It suppose to find previous sibling and copy that text when that particular button is clicked.
Here's my code. I think, I went wrong in the sibling thing. Let me know what I did wrong here:
//finding text to copy
$(document).ready(function(){
$(document).on('click', '.phc-hashtags-box-button', function () {
$(this).closest('.phc-hashtags-box').find('.phc-hashtags-box-tags');
copy = copy +$(this).text();
});
});
function copyToClipboard(element) {
var $temp = $('<input>');
$('body').append($temp);
$temp.val($(element).text()).select();
document.execCommand('copy');
$temp.remove();
}

Instead of picking by class which gets all of the element with that class, limit your find to the parent() div of the button and it will only get the relevant text:
$(document).ready(function(){
$(document).on('click', '.phc-hashtags-box-button', function () {
$(this).parent().find('.phc-hashtags-box-tags'); // notice the change on this line.
copy = copy +$(this).text();
});
});
EDIT:
Working solution:
Now i noticed - you are not passing a single element to copyToClipboard.
<button onclick="copyToClipboard('.phc-hashtags-box-tags')" class="phc-hashtags-box-button">Copy</button>
is sending the saving to copy the last element from 3 found with this. Try instead:
<button onclick="copyToClipboard($(this).parent())" class="phc-hashtags-box-button">Copy</button>
I believe that when you pass '.phc-hashtags-box-tags' to the onclick attr of the button elements, it is matching all of the elements with that class and returning the last match for the value of your function.
Instead, try changing the button onclick handler to:
copyToClipboard($this)
That said, the execCommand function is not working in the provided snippet so verifying is difficult.
Perhaps try passing IDs or try to architect a more elegant solution. So many relative jQuery selectors will inevitably cause bugs as complexity grows.
I would like to show the value "1,000 below" found inside the button on this div using jquery
<div class="showvaluehere">here</div>
<button class="button" data-filter=".1000">1,000 below</button>
I got this so far but not working, it shows the class ".1000"
var syo = $this.attr('data-filter');
$(this).parent().find('.showvaluehere').html(syo);
for clarity, I want the value of the button to be on the
so that it shows like this;
<div class="showvaluehere">1,000 below</div>
Thanks
You are getting value of data-filter attribute, which is .1000
Try this
$('.button').click(function() {
var syo = $(this).text();
$('.showvaluehere').html(syo);
})
Your code is confusing as you're referencing a lot of elements and attributes which seem unrelated to the HTML you've shown and the problem you describe.
That said, you can do what you require by simply setting the text() of the .showvaluehere element to match that of it's neighbouring button, like this:
$('.showvaluehere').text(function() {
return $(this).next('button').text();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="showvaluehere">here</div>
<button class="button" data-filter=".1000">1,000 below</button>
$('.button').click(function() {
$('.showvaluehere').text($(this).text())
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="showvaluehere">here</div>
<button class="button" data-filter=".1000">1,000 below</button>
So i have a div element which will be filled dynamically with others divs using the appendChild Method, this should display a list. The User is now able to sort that list with the JqueryUI Sortable option.I also added some sortable option attribues like follows:
Options:
$("#NameContainer").sortable("option", "axis", "y");
$("#NameContainer").sortable( "option", "containment", "parent" );
LIST
<div id="NameContainer" class="ui-widget">
<div id="Name_1">John</div>
<div id="Name_2">Jack</div>
<div id="Name_3">Charlie</div>
<div id="Name_4">Sawyer</div>
<div id="Name_5">Yin</div>
<div id="Name_6">Ben</div>
</div>
Now comes my problem. The appendChild always inserts the new div at the bottom of the container but i want to to add some space at the bottom of to the Container Div with a "br" or something like that. I want to add that space to make sure that when the user sorts the last item of that list it will get sorted correctly because the "containment" bounds sometimes wont allow to sort under the last item.
<div id="NameContainer" class="ui-widget">
<div id="Name_1">John</div>
<div id="Name_2">Jack</div>
<div id="Name_3">Charlie</div>
<div id="Name_4">Sawyer</div>
<div id="Name_5">Yin</div>
<div id="Name_6">Ben</div>
<br><!--SPACEHOLDER-->
</div>
So here comes my Question is there away to appendChild above a certain element? Like a "br" "div" or "p"?
Try this instead of appendChild:
Please note I have used random value to add in div as I don't have your dynamic value.
check fiddle: https://jsfiddle.net/dqx9nbcy/
<div id="NameContainer" class="ui-widget">
<div id="divspacer"></div>
</div>
<button id="btn">ADD Element</button>
$(document).ready(function(){
$("#btn").click(function(){
var parentnode = document.getElementById("NameContainer");
var existnode = document.getElementById("divspacer");
var rand = Math.floor((Math.random() * 10) + 1);
var newName = document.createElement("div");
newName.setAttribute("id", rand);
newName.setAttribute("value", rand);
newName.setAttribute("class","ui-widget-content");
newName.innerHTML = rand;
parentnode.insertBefore(newName,existnode);
});
});
refer http://api.jquery.com/appendto/ but you need to make sure that your are targeting right tag.
You can try with this code snippet.
HTML Snippet
<div id="NameContainer" class="ui-widget">
<div id="Name1">Name1</div>
<div id="Name2">Name2</div>
<div id="Name3">Name3</div>
<div id="Name4">Name4</div>
<br>
<br>
</div>
Javascript Snippet
$(document).ready(function(){
$("#btn").click(function(){
var containerDiv= $("#NameContainer");
var childList = containerDiv.children("div");
var newElementid = childList.length;
var newName = document.createElement("div");
newName.setAttribute("id", "Name"+(newElementid+1));
newName.setAttribute("value", "Name"+(newElementid+1));
newName.setAttribute("class","ui-widget-content");
newName.innerHTML = "Name"+(newElementid+1);
$(childList[childList.length-1]).after(newName);
});
});
This is specific to a situation where there are some elements in the initial list. The same can be modified for dynamic list of implementation by validating that childList.length is != 0 before using the same.
I want to check if there is only one div with an error class. And if so, I want to .select() the content of the input (that's in the in corresponding input class div).
How would I do such thing?
My attempt which does not work:
if($("div.addition").hasClass(".error").length === 0) {
(this).parent().find('input').select();
}
HTML
<form>
<div class="input">
<input type="text">
<div>
<div class="addition">Message message.</div>
</div>
</div>
<div class="input">
<input type="text">
<div>
<div class="addition">Message.</div>
</div>
<div class="input">
<!-- So in this case this input's content will be selected -->
<input type="text">
<div>
<div class="addition error">Error message.</div>
</div>
</div>
</form>
Here's a jsFiddle that should do it - I mentioned as a comment to your post that you're missing a </div> tag, that is fixed in the fiddle - without it, the jquery selector matches two inputs. Outline of the js:
if ($('div.error').length === 1) {
errorContent = $('div.error').parents('div.input').find('input').val();
alert(errorContent);
}
Here's a plain JavaScript implementation. No need to use jQuery unless you're already using it.
var errors = document.getElementsByClassName('error');
if(errors.length === 1){
//If there is one class with error
var content = errors[0].innerHTML;
} else{
//there is more than one error class.
}
I want to check if there is only one div with an error class.
if ($("div.error").length === 1) {
// Exactly one div with the class "error"
}
else {
// Zero or more than one
}
By using jQuery it can be done like:
$(document).ready(function(){
var div = $('.error');
if(div.length){
var val = div.parents('.input:first').find('input').val();
//val is the value of input
}
});
