jQuery clone and bind event issue

jQuery clone and bind event issue - javascript

I m trying to clone one div with some elements on a tag click event when clone is happening I am changing a tag to delete and bind click event. Whenever I add more clone I will remove a delete tag from all previous clone and keep it on last clone. when user click on last a tag with click event, I will remove last clone tag and add delete to previous clone which will become last clone.
Every thing works until when "delete to previous clone which will become last clone" but my delete a tag will stop working. Kindly let me know what I am doing wrong.
My jsfiddle https://jsfiddle.net/milindsaraswala/6mt29a6x/ (Sorry for not putting any css in my jsfiddle as it is huge)
Sample code of jQuery
$(document).ready(function () {
$(".addFlightBtn").click(function () {
$(".flightRows").append($(".flightRow:first").clone());
$(".flightRow").find(".exclude").removeClass("exclude");
var flightLength = $(".flightRows").children(".flightRow").length;
$(".flightRow:last").find("#lbFlight").html("Flight " + flightLength);
$(".flightRow:last").find(".addFlightBtn").addClass("exclude delFlightBtn").removeClass("addFlightBtn").html("Delete Flight");
$(".flightRow").not(':first').find('a').not('.exclude').remove();
$(".flightRow:last").find(".delFlightBtn").bind("click", function () {
$(this).closest(".flightRow").prev().find(".searchBtnHolder").html('Delete Flight');
$(this).closest(".flightRow").remove();
});
});
});

Your code is fine except use delegate event binding when you adding html
dynamically.
I have only changed your delete event handler this is how. Here's Working Fiddle
$(document).on("click", ".delFlightBtn", function() {
if ($(".flightRow").length > 2) {
$(this).closest(".flightRow").prev()
.find(".searchBtnHolder")
.html('Delete Flight');
}
$(this).closest(".flightRow").remove();
});
After fixing the event handler you will find another problem which is fixed by this line
if ($(".flightRow").length > 2) {
$(this).closest(".flightRow").prev()
.find(".searchBtnHolder")
.html('Delete Flight');
}
$(document).ready(function() {
$(".addFlightBtn").click(function() {
$(".flightRows").append($(".flightRow:first").clone());
$(".flightRow").find(".exclude").removeClass("exclude");
var flightLength = $(".flightRows").children(".flightRow").length;
$(".flightRow:last").find("#lbFlight").html("Flight " + flightLength);
$(".flightRow:last").find(".addFlightBtn").addClass("exclude delFlightBtn").removeClass("addFlightBtn").html("Delete Flight");
$(".flightRow").not(':first').find('a').not('.exclude').remove();
});
$(document).on("click", ".delFlightBtn", function() {
if ($(".flightRow").length > 2) {
$(this).closest(".flightRow").prev().find(".searchBtnHolder").html('Delete Flight');
}
$(this).closest(".flightRow").remove();
});
});

JavaScript hide a corresponding field with specific delimiter

I want to hide the corresponding textarea field of a dropdown, It will be used in a lot of instance that's why I want it on a function.
<div id="formElement1" class="field">
<label for="field1">Start and end date defined</label>
<select id="field1" name="campaign-dd1">
<option value="" >Please Select</option>
<option value="Yes" >Yes</option>
<option value="No" >No</option>
<option value="N/A" >N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement2" class="field">
<label for="field2">Comment(s)</label>
<textarea id="field2" name="campaign-comment1" ></textarea>
</div>
<div id="formElement3" class="field">
<label for="field3">Content and workflow are compliant to requirements</label>
<select id="field3" name="campaign-dd2">
<option value="" >Please Select</option>
<option value="Yes" >Yes</option>
<option value="No" >No</option>
<option value="N/A" >N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement4" class="field">
<label for="field4">Comment(s)</label>
<textarea id="field4" name="campaign-comment2" ></textarea>
</div>
<div id="formElement5" class="field">
<label for="field5">Flow working as planned</label>
<select id="field5" name="campaign-dd3">
<option value="" >Please Select</option>
<option value="Yes" >Yes</option>
<option value="No" >No</option>
<option value="N/A" >N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement6" class="field">
<label for="field6">Comment(s)</label>
<textarea id="field6" name="campaign-comment3" ></textarea>
</div>
As you can see in the code the dropdown name=campaign-dd# has a specific textarea name=campaign-comment#.

On initial load. I want to hide it. And will display it once YES is selected
In this case you can put a common class on all the .field elements which contains the comment fields, in my example below I used .comment and hide them in CSS. Then in JS you can put a change event handler on the select elements which shows/hides the related comment field based on the selected option. Try this:
$('select').change(function() {
$(this).closest('.field').nextAll('.field:first').toggle($(this).val() == 'Yes');
});
.field.comment {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="formElement1" class="field">
<label for="field1">Start and end date defined</label>
<select id="field1" name="campaign-dd1">
<option value="">Please Select</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement2" class="field comment">
<label for="field2">Comment(s)</label>
<textarea id="field2" name="campaign-comment1"></textarea>
</div>
<div id="formElement3" class="field">
<label for="field3">Content and workflow are compliant to requirements</label>
<select id="field3" name="campaign-dd2">
<option value="">Please Select</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement4" class="field comment">
<label for="field4">Comment(s)</label>
<textarea id="field4" name="campaign-comment2"></textarea>
</div>
<div id="formElement5" class="field">
<label for="field5">Flow working as planned</label>
<select id="field5" name="campaign-dd3">
<option value="">Please Select</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
</div>
<div class="clear"></div>
<div id="formElement6" class="field comment">
<label for="field6">Comment(s)</label>
<textarea id="field6" name="campaign-comment3"></textarea>
</div>

Adding classes that makes more sense would be easier, but you can construct the name for the textarea from the name given to the select, to hide it etc.
$('.field select').on('change', function() {
var parts = this.name.split('-');
var numb = parts[1].replace(/\D/g, '');
$('[name="' + parts[0] + '-comment' + numb + '"]').toggle(this.value !== 'Yes')
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<em>Select "Yes" to hide comment</em>
<br><br><br>
<div id="formElement1" class="field">
<label for="field1">Start and end date defined</label>
<select id="field1" name="campaign-dd1">
<option value="">Please Select</option>

<option value="No">No</option>
<option value="N/A">N/A</option>

Reload the bootstrap3 modal with dynamic data

I have a modal which initially has two <div> elements inside. But users can dynamically add additional <div> elements also.
What I want to do is to show only the default two <div>s each time modal is closed and reopened.
I tried the following:
$('#modal').on('show.bs.modal', function () {
$(this).removeData('bs.modal');
});
It did not help.
How can I do this?
Initial modal body:
<div class="modal-body">
<div class="row" id="leg-1">
<div class="col-md-5" id="pickup-info-1">
<div class="row">

<button>Add Leg</button>
The first two divs are initial defaults. When a user presses a Add Leg button, another div with id leg-3 (and so on.) is inserted into the template.

Add a class to the added <div>, ie. '.addedDivClass',
Then use jQuery .remove() to remove the elements when you show the modal.
$('#modal').on('show.bs.modal', function () {
// Get the added divs within the modal and remove them
$('.addedDivClass', this).remove();
});
Read more about remove() here.

try the following:
$('#modal').on('show.bs.modal', function () {
// Get the added divs within the modal and remove all except the first 2
$('div[id^="leg"]').not('#leg-1,#leg-2').remove();
});

This is a problem. I can't get data from forms and also the button doesn't work. I made other forms like this but without JS. This may be the cause. Do you have any suggestions or solutions?
P.S. Sorry for my English ;)

The problem is using required='required' when the form fields are not required.
The user can submit at any time and it is not evident that you must click each radio button in turn to fill out that portion, if that was the intention.
I ran your code as plain HTML and examined the POST data in the Chrome Dev Tools and it works fine if you fill out all fields with required...
You will get an error in console that says the following:
An invalid form control with name='faculty' is not focusable.
Chrome is trying to focus the field to add error messages, but you set style.display = 'none' so it can't.

I don't see anything wrong with the code you posted, per se.
I personally prefer to wrap radio input buttons in the label tag without the for="" attribute. This makes it so clicking on the text also selects the radio button. Like so:
<label class="css-label cb3">
<input type="radio" data-required="true" name="cardType" id="one" class="" value="CC">
Credit Card
</label>
I tested your code in this jsfiddle (granted, I added my radio button change) and it seems to work. There must be something else in your code that is causing the issue. You could try posting a link to your development website.

I encountered probably same problem. Don't use "contenteditable='true'" property.
ERROR EXAMPLE:
<div class="input" contenteditable="true">
<label for="RadioOne"><input type="radio" value="val1" name="radio" id="RadioOne">Radio 1</label>
<label for="RadioTwo"><input type="radio" value="val2" name="radio" id="RadioTwo">Radio 2</label>
</div>
In your case if it isn't "contenteditable" search for other attributes which could interfere.

I think the problem is in your question, not in the code. Radio buttons all have the same name and are treated as a group. This is why the first one is selected with a tab, then to get to individual buttons with the arrow keys. I might have misunderstood the question but I hope its useful.

Hide And show html tab with a drop down menu

here is my code ..i code a php page where i want, if we select scholarship status yes then some options show below like bank name , branch etc and if we select scholarship status no , then not show any option.
<div class="controls">
<select id="" name="Scholarship info">
<option value="">select</option>
<option value="yes">yes</option>
<option value="no">no</option>
</select>
</div>
and if we select yes then show that options otherwise if we select no ..not show below options....
<div class="controls">
<select id="" name="Bank name">
<option value="">select</option>
<option value="state bank">State bank</option>
<option value="Canera Bank">Canera bank</option>
</select>
</div>
<div class="controls">
<select id="" name="Branch name">
<option value="">select</option>
<option value="amethi">amethi</option>
<option value="lucknow">lucknow</option>
</select>
</div>
<div class="controls">
<select id="" name="account number">
<input type="text" class="span6 typeahead" name="acoountnumber" placeholder="account number" value="<?php echo
set_value('accountnumber'); ?>" />
</div>

LIVE DEMO
$(document).ready(function() {
$("select[name='Bank name']").hide();
$("select[name='Branch name']").hide();
$("select[name='account number']").hide();
$("input[name='acoountnumber']").hide();
});
$("select[name='Scholarship info']").change(function() {
var selectedVal = $(this).val();
if(selectedVal == 'yes') {
$("select[name='Bank name']").show();
$("select[name='Branch name']").show();
$("select[name='account number']").show();
$("input[name='acoountnumber']").show();
} else {
$("select[name='Bank name']").hide();
$("select[name='Branch name']").hide();
$("select[name='account number']").hide();
$("input[name='acoountnumber']").hide();
}
});

If you add an extra class, withScholarship to the divs you want to show and hide, it is gets even easier. See this JSFiddle
<div class="controls">
<select id="" name="Scholarship info">
<option value="">select</option>
<option value="yes">yes</option>
<option value="no">no</option>
</select>
</div>
<div class="controls withScholarship">
<select id="" name="Bank name">
<option value="">select</option>
<option value="state bank">State bank</option>
<option value="Canera Bank">Canera bank</option>
</select>
</div>
<div class="controls withScholarship">
<select id="" name="Branch name">
<option value="">select</option>
<option value="amethi">amethi</option>
<option value="lucknow">lucknow</option>
</select>
</div>
<div class="controls withScholarship">
<input type="text" class="span6 typeahead" name="acoountnumber" placeholder="account number" value="121"/>
</div>
<script type="text/javascript">
$(".withScholarship").hide();
$("select[name='Scholarship info']").change(function() {
var flag = $(this).val() == "yes";
$(".withScholarship").toggle(flag);
})
</script>
