How to get the ID of the Current element clicked - javascript

I want to get the Value of the Current Element to be clicked.
I have a list of Checkboxes and selection of each I want to get the ID of it which is hidden.
My Code goes as follows:
$("#ModelListView").on("click", ".ModelCheckBox", function (element) {
var AnalysisID = $("#AnalysisID").val();
var ModelID = '';
});
HTML:
<div id="ModelListView"></div>
<script type="text/x-kendo-template" id="Modeltemplate">
<div class="section group fr">
<div class="col span_2_of_12">
#if(ACTIVE_MODELS_COUNT > 0){# <input class="ModelCheckBox" type="checkbox" checked/>#} else {# <input class="ModelCheckBox" type="checkbox" unchecked/> #}#
</div>
<div class="col span_4_of_12"><label>#:MODEL#</label></div>
<input id="Model_ID" type="hidden" value=#:MODEL_ID#/>
</div>
</script>
I want to get the Value of Model_ID that is kept hidden.

You can use $(this) and get the closest.
$(this) will be the element that's clicked.
.closest('.section.group') will return the "section group"-div. You might want to use #ModelListView instead of .section.group.
.find('#Model_ID').val() will return the value of the hidden field.
$("#ModelListView").on("click", ".ModelCheckBox", function (element) {
var AnalysisID = $("#AnalysisID").val();
var ModelID = $(this).closest('.section.group').find('#Model_ID').val();
alert(ModelID);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="ModelListView">
<div class="section group fr">
<div class="col span_2_of_12">
<input class="ModelCheckBox" type="checkbox" checked/>
</div>
<div class="col span_4_of_12"><label>Label</label></div>
<input id="Model_ID" type="hidden" value="someValue"/>
</div>
</div>
Sidenote: be aware of using an ID in a template.

Show / Hide Elements within the same parent div

I'm having trouble getting a div ('.option-other') within a parent group ('.other-row') to show/hide when the corresponding option of the select element ('.select-toggle') is selected. Right now if "other" is selected from either question set 1 or 2 it will show both of the '.option-other' divs. I tried using .parent() and .closest() as described in this solution, but can't seem to figure out the proper way to utilize it for this use case.
$(".select-toggle").change(function() {
var oth = false;
$(".select-toggle option:selected").each(function() {
if ($(this).val() == "other") oth = true;
});
if (oth) $('.option-other').show();
else $('.option-other').hide();
// tried this method as well but still doesnt work
// if (oth) $(this).closest('.other-row').children('.option-other').show();
// else $(this).closest('.other-row').children('.option-other').hide();
}).change();

// you wrote:

You're close, but $.children only selects direct children of each .other-row. Since .option-other is inside .col inside .other-row, $.children can't see it. Use $.find instead.
// your original code:
var oth = false;
$(".select-toggle option:selected").each(function() {
if ($(this).val() == "other") oth = true;
});
This sets one visibility value for the entire page: if at least one "other" option is selected, anywhere, show all the text inputs. The change event is fired for the <select> that actually changed, so focus your efforts there:
var oth = false;
$(this).children("option:selected").each(function() {
if ($(this).val() == "other") oth = true;
});
if (oth) $(this).closest('.other-row').find('.option-other').show();
else $(this).closest('.other-row').find('.option-other').hide();
This works, but it could be cleaner. Showing or hiding an element based on a boolean is a common enough requirement that jQuery has a function for it: $.toggle. You can replace the if/else lines with
$(this).closest('.other-row').find('.option-other').toggle(oth);
Your $.each loop does one thing: set oth if there exists at least one selected <option> with a value of "other". You can get the same logic as a one-liner by using an attribute selector:
var oth = ($(this).find('option:checked[value="other"]').length !== 0);
(I changed :selected to :checked because you're already filtering on option elements, and :selected has a performance penalty.)
The final version:
$(".select-toggle").change(function() {
var oth = ($(this).find('option:checked[value="other"]').length !== 0);
$(this).closest('.other-row').find('.option-other').toggle(oth);
}).change();

Vanilla JS version:
document.querySelectorAll('.select-toggle').forEach(el => {
el.addEventListener('change', evt => {
const oth = evt.target.querySelector('option:checked[value="other"]');
evt.target
.closest('.other-row')
.querySelector('.option-other')
.style.display = (oth ? '' : 'none');
});
// trigger change event programmatically
const event = document.createEvent('HTMLEvents');
event.initEvent('change', true, false);
el.dispatchEvent(event);
});
Here is a solution that is a little clunky but I did it relatively quick. It's kind of a work around for having to know which of your two selectors with the same class had been selected.
Here is a working example using your code.
$(".select-toggle").change(function () {
var oth = false;
$(".select-toggle option:selected").each(function () {
if ($(this).val() == "otherFood") {
oth = true;
$('.option-other-food').show();
} else {
$('.option-other-food').hide();
};
if ($(this).val() == "otherDrink") {
oth = true;
$('.option-other-drink').show();
} else {
$('.option-other-drink').hide();
};
});
}).change();

Asp.net core delete button not working properly

I have a view like this:
<div class="GridContainer">
<div>
<div class="row gridHeader">
<div class="small-9 columns">Member Name</div>
<div class="small-2 columns">Date Registered</div>
</div>
#foreach (var member in Model.Members)
{
<div class="row">
<div class="small-9 columns">#member.MemberName</a></div>
<div class="small-2 columns">#member.DateRegistered</div>
<input type="hidden" asp-for="#member.Id" />
<a id="btnMemberDelete" href="#">Delete</a>
</div>
}
</div>
my javascript:
<script type="text/javascript">
$(document).ready(function () {
$('#btnMemberDelete').click(function () {
var id = $(this).closest("div").find("input:hidden[name='member.Id']").val();
var url = '#Url.Action("DeleteMembers", "Member")' + "?id=" + id;
openMemberDialog(url);
});
});
</script>
The delete button only works for the very first row at the moment. If say I have 4 rows the other 3's delete button won't even register. It won't even open the dialog box. Is there something I'm missing here as the code seems to be correct to me.
Thanks!
Fiddle here
As answerd above you need to have a uniqe ID or use a class. in my solution above I use a class like so:
$(document).ready(function () {
$('.btnMemberDelete').click(function (e) {
e.preventDefault();
var id = $(this).closest("div").find("input:hidden[name='member.Id']").val();
console.log(id)
});
});
Also correct your html:
#foreach (var member in Model.Members)
{
<div class="row">
<div class="small-9 columns">#member.MemberName</a></div> // remove the '</a>' here
<div class="small-2 columns">#member.DateRegistered</div>
<input type="hidden" asp-for="#member.Id" />
<a class="btnMemberDelete" href="#">Delete</a>
</div>
}
You need to give a unique id for each delete button. Or you can give a classname instead of id to your anchor tag.
<div class="GridContainer">
<div>
<div class="row gridHeader">
<div class="small-9 columns">Member Name</div>
<div class="small-2 columns">Date Registered</div>
</div>
#foreach (var member in Model.Members)
{
<div class="row">
<div class="small-9 columns">#member.MemberName</a></div>
<div class="small-2 columns">#member.DateRegistered</div>
<input type="hidden" asp-for="#member.Id" />
<a class="btnMemberDelete" href="#">Delete</a>
</div>
}
</div>
<script type="text/javascript">
$(document).ready(function () {
$('.btnMemberDelete').click(function () {
var id = $(this).closest("div").find("input:hidden[name='member.Id']").val();
var url = '#Url.Action("DeleteMembers", "Member")' + "?id=" + id;
openMemberDialog(url);
});
});
</script>

Need to append html element as user keep clicking a button with jquery

I am trying to append a div multiple times when clicking a button, the problem is that is only appending once. I need to append same div as user keeps clicking.
DIV I need to append multiple times is stored in a variable named $htmlDivForm in the jquery code.
I'm using bootstrap.
HTML code:
<div class="container">
<div class="row">
<div class="col-md-3">
<form id="formUser" action="index.html" method="post">
<div class="text-center">
<button id="moreFieldsBtn" class="btn" type="button" name="button">+</button>
</div>
</form>
</div>
<div class="col-md-9">
More Content...
</div>
</div>
</div>
jquery code:
var $moreFieldsBtn = $("#moreFieldsBtn");
var $formUser = $("#formUser");
var $htmlDivForm = $('<div class="form-group"><label class="labelName" for="inputText">Nombre</label><input class="form-control inputTextField" type="text" name="inputText" value=""></div>');
//Add input text field
$($moreFieldsBtn).click (function() {
$($formUser).append($htmlDivForm);
});
I had gone through your question.
I have Updated the example.
Removed the Object and just inserting plain HTML
var $moreFieldsBtn = $("#moreFieldsBtn");
var $formUser = $("#formUser");
var $htmlDivForm = $('<div class="form-group"><label class="labelName" for="inputText">Nombre</label><input class="form-control inputTextField" type="text" name="inputText" value=""></div>');
var htmltext = '<div class="form-group"><label class="labelName" for="inputText">Nombre</label><input class="form-control inputTextField" type="text" name="inputText" value=""></div>'
//Add input text field
$($moreFieldsBtn).click (function() {
$($formUser).append(htmltext);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="row">
<div class="col-md-3">
<form id="formUser" action="index.html" method="post">
<div class="text-center">
<button id="moreFieldsBtn" class="btn" type="button" name="button">+</button>
</div>
</form>
</div>
<div class="col-md-9">
More Content...
</div>
</div>
</div>
<div>
You can't append the same div multiple times, you need to instantiate new divs and attach those. You also don't need to re-wrap the jQuery objects to attach the handlers:
var $moreFieldsBtn = $("#moreFieldsBtn");
var $formUser = $("#formUser");
//Add input text field
$moreFieldsBtn.click(function() {
var $htmlDivForm = $('<div class="form-group"><label class="labelName" for="inputText">Nombre</label><input class="form-control inputTextField" type="text" name="inputText" value=""></div>');
$formUser.append($htmlDivForm);
});

Jquery - find next element in each loop

I have a question like so.
I have HTML structure:
<form id="form">
<div class="row">
<div class="item-input">
<label for="A1">A1</label>
<input type="text" name ="A1" />
<span class="input-require">(*)</span>
<span class="info">(Enter A1)</span>
</div>
<div class="item-input">
<label for="A2">A2</label>
<input type="text" name ="A2" />
<span class="input-require">(*)</span>
<span class="info">(Enter A2)</span>
</div>
</div>
<div class="row">
<div class="item-input">
<label for="B1">B1</label>
<input type="text" name ="B1" />
<span class="input-require">(*)</span>
<span class="info">(Enter B1)</span>
</div>
<div class="item-input">
<label for="B2">B2</label>
<input type="text" name ="B2" />
<span class="input-require">(*)</span>
<span class="info">(Enter B2)</span>
</div>
</div>
...
</form>
Now I want to selected 'span' has class "info" behind input[type=text] each.
I try:
<script type="text/javascript">
$(document).ready(function() {
$("#form input[type=text]").each(function(){
var spanInfo = $(this).closest("item-input").next().find('span.info');
console.log(spanInfo.text()); // Result is empty
});
});
</script>
Why is empty? Help me please. How do I, thanks
var spanInfo = $(this).closest("item-input").next().find('span.info');
Should be
var spanInfo = $(this).closest(".item-input").next().find('span.info');
You are missing the . (dot, class)
Your mean is show "(Enter A2)" and "(Enter B2)" or show all 4 element value: (Enter A1), (Enter A2), (Enter B1), (Enter B2)
If only show 2 value then CODE HERE
else You want to show 4 value, you can code:
$(document).ready(function() {
$("#form input[type=text]").each(function(){
var spanInfo = $(this).closest(".item-input").find('span.info');
console.log(spanInfo.text());
});
});

Javascript Remove a Template Element

I have a template that I will simplify as follows:
<script type="text/template" id="contactTemplate">
<div id="contactentry" class="row contact-info">
</div>
<div class="form-group">
<label for="name1">First Name</label>
<input type="text" class="form-control" id="FirstName" name="Contacts[{{ID}}].FirstName" required>
</div>
<div class="form-group minus">
<label for="contactMinus{{ID}}"> </label>
<a id="depminus{{ID}}"><i class="fa fa-minus-circle"></i>Remove</a>
</div>
</script>
I allow insertion of the template, multiple times via the following code, this part works:
<script type="text/javascript">
var clone = (function () {
var cloneIndex = -1;
var template = $('#contactTemplate').text();
return function () {
//Replace all instances of {{ID}} in our template with the cloneIndex.
return template.replace(/{{ID}}/g, ++cloneIndex);
}
})();//self executing function.
var contacts = $('#contacts')
$("#contactadd").on("click", function () {
contacts.append(clone());
window.controlManager.FindControls(contacts);
});
</script>
<div id='contacts'>
<div class="col col-lg-1">
<a id="contactadd"><i class="fa fa-plus-circle"></i>Add</a>
</div>
</div>
Now I am trying to figure out how to make javascript code to remove each element when/if the minus button is clicked (in the template).
I'm not sure what kindof code I could then use to delete the contacts, via the depminus{{ID}} control. Any tips to get me started?
