I use the following:
var transferTemplate = $('#transfersRow').html();
in order to store some html code in a variable, which results to:
<div class="form-group row">
<div class="col-lg-4">
<label for="inc[1].a">Counterparty</label>
<input type="text" class="form-control" id="inc[1].a"
name="inc[1].a" placeholder="Enter Counterparty">
</div>
</div>
Now I would like to be able to remove all labels from the html code. I tried:
$(transferTemplate).find(label).remove();
$(transferTemplate).remove('label');
$(transferTemplate).filter('label').remove();
but none works.
First, you need to select the row that you want to remove labels at each row:
Like this:
$(".row").each(function( index ) {
$(this).find("label").remove(); //find label at each row and remove.
});
I hope that helps.
I think that you are misunderstanding the result of html(). It doesn't return a Jquery DOM object. The result is just a string representation. Just remove the .html() and I'm sure you will be able to call the functions you want.
var transferTemplate = $('#transfersRow');
This returns a string representation of the HTML:
var transferTemplate = $('#transfersRow').html();
You could remove the label from this string like this:
$(transferTemplate).find('label').remove();
However, all that does it create a new jQuery object with the HTML minus the label. It won't update the transferTemplate variable.
Instead, you could assign $(transferTemplate) to a new variable.
That would allow you to remove the label and still have access to the updated HTML.
Snippet
var transferTemplate = $('#transfersRow').html(),
template = $(transferTemplate);
template.find('label').remove();
$('textarea').val(template.html());
textarea {
width: 100%;
height: 10em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="transfersRow">
<div class="form-group row">
<div class="col-lg-4">
<label for="inc[1].a">Counterparty</label>
<input type="text" class="form-control" id="inc[1].a" name="inc[1].a" placeholder="Enter Counterparty">
</div>
</div>
</div>
<hr>
<strong>Output</strong>
<textarea></textarea>
Well, I guess the correct way is: $(transferTemplate).find('label').remove();

I have a list of divs on a page. I have a filter system that fills in a 'data-' element with a possible list of values.
Example:
<div data-myvalues="value1,value2,value3"></div>
<div data-myvalues="value2,value3"></div>
<div data-myvalues="value1,value2"></div>
<div data-myvalues="value1,value3"></div>
Then I have some jQuery that tries to filter based on some selections that include the values in the data-myvalues attribute. However, the jQuery filter does not quite work because I think it sees the values as including the comma (,) in the value.
How, in jQuery, would I filter based on an if the divs include the values or not. I am currently using the jQuery
$("div[data-myvalue*='value1']").show();
But it seems to now quite work for some reason it will work if the data-myvalues only has one value in it, the jQuery works, but if there are multiples separated by a comma, the jQuery does not work.
I have a JS fiddle here with a simple sample code I was messing with to get the proof of concept to work.

Is there a better way to list values on an element then filter them?
Thanks in advance.
You can try something like this:
$(document).ready(function() {
$.each($('div'), function(i, v){
var values = $(v).data('myvalues');
if(values.indexOf('value1') != -1) {
$(v).show();
} else {
$(v).hide();
}
})
});
And html content with data values:
<div data-myvalues="value1,value2,value3"></div>
<div data-myvalues="value2,value3"></div>
<div data-myvalues="value1,value2"></div>
<div data-myvalues="value1,value3"></div>
Hope this helps.
The data attribute takes JSON object which you can take advantage of.
Given the following element:
<input data-nations='["anothernation", "nationman", "country"]' type="text" value="Germany">
You could filter the desired elements based on the target value:
var targetNation = "nationman";
$("input[data-nations]")
.filter(function () {
// Returns the list as array
return $(this).data("nations").indexOf(targetNation) > -1;
})
.css("background-color", "blue");
Note the two differences between the quotes:
// will parse correctly
data-nations='["anothernation", "nationman", "country"]'
// will NOT parse correctly since it will be treated as plain text
data-nations="['anothernation', 'nationman', 'country']"
Try with .not() like the following way:
$(document).ready(function(){
$("input[data-me*='nationman']").css("background-color", "yellow");
$("input").not("[data-me*='nationman']").css("background-color", "red");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input data-me="nationality" type="text" value="Chinese">
<input data-me="nationman" type="text" value="English">
<!--This doesn't work with more than one value-->
<input data-me="nationman,country" type="text" value="Germany">
<input data-me="anothernation" type="text" value="Norwegian">
<p>This selector selects all input fields with the attribute name that contains the string 'nation'.</p>
You can also loop through all elements with .each():
$(document).ready(function() {
$('[data-myvalues]').each(function(){
var values = $(this).data('myvalues');
if(values.includes('value1'))
$(this).show();
else
$(this).hide();
})
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div data-myvalues="value1,value2,value3">value1,value2,value3</div>
<div data-myvalues="value2,value3">value2,value3</div>
<div data-myvalues="value1,value2">value1,value2</div>
<div data-myvalues="value1,value3">value1,value3</div>
Checkout the snippet;
I have modified you code a litte bit, hope this will help to get your answer;
This is a little bit tricky answer, but you can easily understand the code
$(document).ready(function(){
var el = $('input');
el.each(item =>{
var attr = el[item].dataset
if(attr.me.match(/nationman/)){
el[item].setAttribute('style', 'background-color:yellow')
}else{
el[item].setAttribute('style', 'background-color:red')
}
})
});

<input data-me="anothernation" type="text" value="Norwegian">
<p>This selector selects all input fields with the attribute name that contains the string 'nation'.</p>

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 want to append a duplicate of an input box in a parent box. Here is my HTML structure:
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link
And here is my jQuery code:
function addPlaceholder(parentClass){
var placeHolder = $(parentClass).children().eq(0);
$(parentClass).append(placeHolder);
console.log(placeHolder);
}
$('.add-reading-btn').click(function(){
addPlaceholder('.reading-group');
});
Here is the jsfiddle link: https://jsfiddle.net/abhishekraj007/kexe6gxn/
What am I doing wrong?
Your code is taking the existing <input> element and moving it from the <div> and back into the <div>, so it looks like nothing is happening. If you .clone() the element and then .append() it, a new element will be added.
Here is a working example:
function addPlaceholder(parentClass) {
var placeHolder = $(parentClass).children().eq(0).clone();
$(parentClass).append(placeHolder);
console.log(placeHolder);
}
$('.add-reading-btn').click(function() {
addPlaceholder('.reading-group');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link
If you want to add focus to your <input> element on load, you can do so by adding this line to the bottom of your code:
$('#link').focus();
If you want to add focus to the new element on creation, as well as give it an empty value rather than copying the prior element's value, add this line to the end of your addPlaceholder() function:
$(placeHolder).val("").focus();
you can just add the .clone() method of jquery to create a clone of the textbox like below . You were only referring to the same element not the cloned html before.
$(document).ready(function(){
function addPlaceholder(parentClass){
var placeHolder = $(parentClass).children().eq(0).clone();
$(parentClass).append(placeHolder);
//console.log(placeHolder);
}
$('.add-reading-btn').click(function(){
addPlaceholder('.reading-group');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link
Here is a working fiddle

I have a datepicker in a div with class pickergroup, I have 3 datepicker in my page, and this is why I use a group and different names
<div class="pickergroup">
<input type="text" name="day1" id="day1"/> /
<input type="text" name="month1" id="month1"/> /
<input type="text" name="year1" id="year1"/>
<input type="hidden" id="date1" name="date1"/>
<div id="datepicker1" name="calendar"></div>
</div>
In my jquery I want to detect when clicking the id wich starts with "datepicker", I guess something like:
$(document).on('click', '.pickergroup id^="datepicker"', function() {
$(".pickergroup").find('[id^="datepicker"]').datepicker({
//my datepicker code
});
});
but this is not correct.
how can I do it?
The problem is how you're selecting the element inside of the event handler.
$(".pickergroup").find('[id^="datepicker"]')
means "find all elements with the class of pickergroup. Find all of their children which have an ID starting with datepicker." Instead, you want to use this and fix your selector from
.pickergroup id^="datepicker"
to
.pickergroup [id^="datepicker"]
$(document).on('click', '.pickergroup [id^="datepicker"]', function() {
var $this = $(this); // The div that was clicked
console.log($this.text());
});
.pickergroup div {
float: left;
margin-right: 1em;
width: 200px;
height: 200px;
background: #0F0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="pickergroup">
<div id="datepicker1">A</div>
</div>
<div class="pickergroup">
<div id="datepicker2">B</div>
</div>
<div class="pickergroup">
<div id="datepicker3">C</div>
</div>
<div class="pickergroup">
<div id="can-t-click-me">D</div>
</div>
First of all, the datepicker element needs to be an input. And remember, ID's are unique. If you using starts with selector, it is ok. But please dont get confusing with this.
Second, why need seperate fields? You could use one datepicker, decide the format you want to display and you could also parse the returned value from the datepicker in the format you need/want. Please have a look at the documentation.
Basically I've managed to become stuck yet again trying to duplicate a DIV and it's form elements using jQuery.
Button:
<div class="addNew" id="addSkill">Add Skill <i class="icon-plus"></i></div>
Div and contents I wish to duplicate
<div class="row" id="skiller">
<div class="label">Skill</div>
<div class="input"><input class="lineput" placeholder="Doing stuff."></div>
</div>
I've tried using the clone method, I just can't seem to create a functioning line of code that will duplicate it beneath the first div, and make it ready for PHP multiple data entry.
Thanks!
Something like this would be a start:
$("#addSkill").click(function(e){
e.preventDefault();
var new_skiller = $("#skiller").clone();
new_skiller.attr("id", "skiller-"+$(".row").length);
new_skiller.insertAfter(".row:last");
});
You need to clone and then append() the item inside a div like so:
HTML
<div class="thing">
<div class="row" id="skiller">
<div class="label">Skill</div>
<div class="input"><input class="lineput" placeholder="Doing stuff."></div>
</div>
</div>
<div class="addNew" id="addSkill">Add Skill <i class="icon-plus"></i></div>
jQuery
$(document).ready(function(){
$('#addSkill').click(function(){
var thing = $('#skiller').clone();
$('.thing').append(thing);
});
});
View the jsFiddle Demo....
Note: you'll need to give them seperate names/make it an array to access
Try this. should work. Note: ID can not be duplicated. the following code will duplicate div with id as well.
$(document).ready(function(){
$('#addSkill').click(function(e) {
var skiller = $('#skiller').clone();
$( "#skiller" ).after( skiller );
});
});
