I'm currently working on a dynamic form which enables the user to add as many variants as they would like. This form which can be added has a price, size and color. The size and color are select2 select boxes which enable the user to select multiple things. The form:
<div class="col-sm-4">
<label>Kleuren</label>
<select name="colors[{{$i}}][]" id='color-options' class="form-control multiple-select" multiple="multiple">
#foreach($colors as $id=>$color)
<option value="{{$id}}">{{$color}}</option>
#endforeach
</select>
</div>
When looking at the HTML code I have multiple of these forms which go by name: colors[0][], colors[1][], colors[2][] etc.
How do I print the value of a selected new color in a new div? The code which I have thus far:
$(document).ready(function() {
$('.multiple-select').select2({
language: 'nl'
});
$('.summernote').summernote();
var addVariantButton = document.getElementById('addVariant[0]');
addVariantButton.addEventListener('click', function(){
addVariant(0);
});
var colorSelected = document.getElementsByName('colors[0][]');
colorSelected.addEventListener("click", displayColorSelected);
});
function displayColorSelected() {
var selected_value = document.getElementById("color-options").value;
console.log(selected_value);
}
But this only works for the first colors input form, but how can I make this into a more dynamical function to get all colors input?
You can get all selected values in array as below:
function displayColorSelected() {
var selected_value = $("[id='color-options']").toArray().map(x => $(x).val());
console.log(selected_value);
}
Note: id selector will always return single element which will be first with that id. So you're getting value for first select only.
You can use attribute selector ([]) instead which will find every element with given id. So here $("[id='color-options']").toArray() will find every element with id equal to color-options and map(x => $(x).val()) will return only value part from the elements array.
Add all the selects a class ("color-select" for example), and run over all the selects -
$('.color-select').each(function() { console.log($(this).val()); })
You may need to delegate your event listener
document.addEventListener('event',function(e){
if(element){//do something}
})
Since you are using jquery its easier
$(document).on('event','element',function());

I want to make a form in which the next field appears based on input done in the previous field by the user.
eg: If The user selects Beverages then below it show a fieldset with different beverages with checkbox, and if user select snacks then below it show fieldset with snacks items
I was trying it to do like this:
<select id="first-choice">
<option selected value="base">Please Select</option>
<option value="beverages">Beverages</option>
<option value="snacks">Snacks</option>
</select>
<br>
<select id="second-choice">
<option>Please choose from above</option>
</select>
JSON Data
{
"beverages": "Coffee,Coke",
"snacks": "Chips,Cookies"
}
Jquery
$("#first-choice").change(function() {
var $dropdown = $(this);
$.getJSON("jsondata/data.json", function(data) {
var key = $dropdown.val();
var vals = [];
switch(key) {
case 'beverages':
vals = data.beverages.split(",");
break;
case 'snacks':
vals = data.snacks.split(",");
break;
case 'base':
vals = ['Please choose from above'];
}
var $secondChoice = $("#second-choice");
$secondChoice.empty();
$.each(vals, function(index, value) {
$secondChoice.append("<option>" + value + "</option>");
});
});
});
I not only want append select option, I actually want to make a new division with text fields and file uploads etc
just guide me how to do it in a compact/dynamic way
By all means keep the JS that fills the selector elements (but make your options map a thing that's known before the user even gets to pick anything: don't rely on a network transfer for that!), but don't try to get the whole "conditional showing" to work in JS: CSS can already do that, and it'll do it better. You just need to remember to use the correct HTML markup:
// Load this script via src="..." with `async` and `defer` attributes
// so that it'll run before the user gets to interact with the page,
// after the DOM has been constructed. A feature that's been available
// since IE11, so there's no reason to still put scripts at the end of
// the page, or listening for DOMContentLoaded/ready events.
const first = document.getElementsByName('first-value')[0];
const second = document.getElementsByName('second-value')[0];
const initial = second.innerHTML;
// Either hard code this, or get it on page load, just make sure
// it's already available before users start picking values!
const optionMap = {
a: ['i', 'j', 'k'],
b: ['u', 'v', 'w'],
c: ['x', 'y', 'z'],
};
function addOption(selectElement, text) {
let option = document.createElement('option');
option.value = text;
option.textContent = text;
selectElement.append(option);
}
// Fill the first selector
Object.keys(optionMap).forEach(text => addOption(first, text));
// And only fill the second selector when we know the first value
first.addEventListener('change', evt => {
second.innerHTML = initial;
optionMap[evt.target.value].forEach(text => addOption(second, text));
});
select:not(:valid) {
border: 1px solid red;
}
select:not(:valid) + .followup {
display: none;
}
<select required name="first-value">
<option disabled selected>please select one</option>
</select>
<select required class="followup" name="second-value">
<option disabled selected>please select one more</option>
</select>
The trick here is to make sure you have an option that is both disabled and selected. The latter because <select> elements always have an option selected, but any option marked as disabled does not count as a valid choice (this lets you for instance put labels in a selector element).
So, we make a first <option> that is simply a label, but also make sure the selector always starts with that option selected. As it's disabled, that makes the selector invalid as far as form posting is concerned, so we can use the CSS :valid pseudo class to do all kinds of useful things, like hiding any adjacent element until the main select element is valid.
And of course you can still "fill" the second selector using JS, with an event listener on the first selector so that its change triggers some JS that appends a bunch of option elements to the second one, but this is really something you want to do without a network request: have your code already know which primary values map to which arrays of secondary values by doing a fetch for the full mapping on pageload, or even hardcoded it (e.g. during your site building step, or even manually)
I am writing a filtering function, in which I need to select the elements that have a certain value in their data attribute, and those values are included in an array, allow me to explain it in an example:
For example, I have three elements and a button as follows:
<div data-foo="aa,cc,ff" ></div>
<div data-foo="bb,cc,ff" ></div>
<div data-foo="bb,dd,ee" ></div>
<div class="button" data-boo="aa,ff" ></div>
The data-foo in each element contains comma-separated values. When I click on the button, I create an array (myArray in the code below) from its data attribute, then I need to select those elements that at least one of the values in that myArray is in their data-foo, for a clear explanation please see the code below:
$( ".button" ).click(function() {
// First I make an array from the button's data attribute
var myArray = $(this).data('boo').split(',');
// Select should be elements that their da-foo has at least one
// — of values in the array above
var Select = "?"
});
How the Select variable can target the first two elements, since the first one has both "aa" and "ff", and the second element has "ff".
I really tried to put it the way that makes sense, if it is not clear enough, please let me know and I will be happy to explain more, thank you.
You can use Attribute Contains Selector:
$( ".button" ).click(function() {
// First I make an array from the button's data attribute
var myArray = $(this).data('boo').split(',');
// produces array of strings like '[data-foo*="aa"]'
var selectors = myArray.map(function(value) {
return '[data-foo*="' + value + '"]';
});
// searches by selectors joined by comma, returns all elements
// that satisfy at least one selector
var selectedElements = $(selectors.join(','));
});
Lets use Array.prototype.some for this:
$(".button").click(function() {
// First I make an array from the button's data attribute
var myArray = $(this).data('boo').split(',');
// Select should be elements that their da-foo has at least one
// — of values in the array above
var Select = $("div[data-foo]"); //select all elements with data-foo
Select.each(function(index, element) {
var isInMyArray = $(element).data("foo").split(",").some(function(element) {
if ( myArray.indexOf(element) != -1)
{return true;}//if true then element is in myArray
}); //using some here - if one value is found in array return true.
console.log(isInMyArray);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div data-foo="aa,cc,ff"></div>
<div data-foo="bb,cc,ff"></div>
<div data-foo="bb,dd,ee"></div>
<div class="button" data-boo="aa,ff">test</div>
I have a table data which is generated dynamically via a loop. The td contains a hidden field. below is the code for the same:
<td class="gridtd" id = "r<%=RowNumber%>c<%=ColumnNumber%>">
<input id="hiddendata" type="hidden" value="<%: item.Key%>"/>
</td>
I need to extract the value of the hidden field based on the td selected using jQuery. Please help me get the correct jquery code.
Just select your input and take the value (val()):
$("#hiddendata").val();
If you want to take all hidden input values:
$("input[type='hidden']").each(function () {
console.log($(this).val());
});
Note that the element ids must be unique.
I need to extract the value of the hidden field based on the td selected using jQuery.
If by select you mean, click, you can simply pass this when getting the value:
$("td").on("click", function () {
console.log(
$("[type='hidden']", this).val()
);
});
For your general knowledge, if you do $("#hiddendata", this).val(); inside of the click handler, it will return the correct value (even having multiple ids with the same value).
But definitely, the ids must be unique.
Use this :
$('#hiddendata').val();
$('td').click(
function(event)
{
$(event.target).find('#hiddendata').val();
}
);
It ll give the hiddendata value based on td selection
This will give the value of the hidden field for the selected td.
$('.gridtd').click(function(){
console.log($(this).find('input').val());
});
$('.gridtd').click(function(){
console.log($(this).find('input[type=hidden]').val());
});
You can try this:
$('.gridtd').each(function(){
var currentId = $(this).attr('id');
var hiddenval = $('#'+currentId).find('input[type=hidden]').val();
alert(hiddenval);
})
I've posted my full code on jsfiddle. I'm trying to show the user selected seats here. If user selected 2 from BS the result should be BS-2. Again if user selected 4 from FC the result should be added with the old one like BS-2, FC-4.
But, I've tried something here. its show the value of span element but if i selected the another one it replaces the previous one. How to add a comma and show the multiple selected span values in jquery?
JsFiddle
jQuery
$(".text").click(function(){
$(this).toggleClass('selected');
var data = $(this).text();
$('.returndata').text(data);
})
Try
var $texts = $(".text").click(function () {
$(this).toggleClass('selected');
var selected = $texts.filter('.selected').map(function () {
return $.trim($(this).text())
}).get()
$('.returndata').text(selected.join());
})

I am replicating the functionality of a select/multiselect element and I'm trying to use this function to display the items which have been selected in the relevant container. I need to show all the values that have been selected in a comma-separated list, but it's currently only showing one selection (the last one made). It's also displaying the checkbox, background color, etc. of the list item selected instead of the checkbox value (i.e. value="Black").
I'm using this for a few multiselect form elements where I couldn't use the jQuery UI MultiSelect Widget because they needed to be styled in a very specific way (options displayed with background colors or images and spread out over several columns, etc.).
I've included the relevant code below, and I've posted a working example of the styled 'faux'-multiselect element here: http://jsfiddle.net/chayacooper/GS8dM/2/
JS Snippet
$(document).ready(function () {
$(".dropdown_container ul li a").click(function () {
var text = $(this).html();
$(".dropdown_box span").html(text);
});
function getSelectedValue(id) {
return $("#" + id).find("dropdown_box span.value").html();
}
});
HTML Snippet
<div class="dropdown_box"><span>Colors</span></div>
<div class="dropdown_container">
<ul>
<li><a href="#"><div style="background-color: #000000" class="color" onclick="toggle_colorbox_alt(this);" title="Black"><div class=CheckMark>✓</div>
<input type="checkbox" name="color[]" value="Black" class="cbx"/></div>Black</a>
</li>
<!-- More list items with checkboxes -->
</ul>
</div>
I've tried several other methods (including many of the ones listed here: How to retrieve checkboxes values in jQuery), but none of those worked with hidden checkboxes and/or the other functions I need to incorporate in these particular form elements.
well, to start with change click(..){..} in document.ready to
$(".dropdown_container ul li a").click(function () {
var text = $(this).html();
var currentHtml = $(".dropdown_box span").html();
var numberChecked = $('input[name="color[]"]:checked').length;
$(".dropdown_box span").html(currentHtml.replace('Colors',''));
if (numberChecked > 1) {
$(".dropdown_box span").append(', ' + text);
} else {
$(".dropdown_box span").append(text);
}
});
this will do the appending of text right.
however I couldn't understand the handling of images in the code.
Update, to handle just the value:
replace var text = $(this).html(); with
var text = $(this).find("input").val();
It might be easier to just grab all the values of the check boxes whenever the click event is triggered and then append the values to your span. Like http://jsfiddle.net/9w95b/
I would also suggest not putting the <input> tags inside your <a> tags.
