I have a div in that div I have two input fields and update button like this:
<button type = "button" id = "add-botton" >Add Element </button>
<div id = "trace-div1" class = "trace">
<h4><span>Trace 1</span></h4>
<form>
<table>
<tbody>
<tr>
<td><label>X Axis: </label></td>
<td><input type="text" name="t_x_axis" class = "t_x_axis" id="x_axis_t1" size="50">
</td>
</tr>
<tr>
<td><label>Y Axis: </label></td>
<td><input type="text" name="t_y_axis" class = "t_y_axis" id="y_axis_t1" size="50"></td>
<td><button type = "button" name = "update-button-trace" class = "update-trace" id =
"update-botton-trace1" onclick="updatebtn(this)">Update </button></td>
</tr>
</tbody>
</table>
</form>
</div>
<script>
$(document).ready(function(){
$('#add-botton').click(function(){
var $div = $('div[id^="trace-div"]:last');
var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;
var $trace1div = $div.clone(true).prop('id', 'trace-div'+num );
$trace1div.find('span').text('Trace ' + num);
$trace1div.find("input[name='t_x_axis']").attr("id", "x_axis_t"+num).val("");
$trace1div.find("input[name='t_y_axis']").attr("id", "y_axis_t"+num).val("");
$trace1div.find("button[name='update-button-trace']").attr("id", "update-button -
trace"+num);
$div.after( $trace1div);
});
});
function updatebtn(el){
var id = $(el).attr('id');
}
}
</script>
Here I am cloning my div multiple times with diff.id's ,my problem is when I click update button i need those respective two input values.
I tried like this but here I am getting all input value like if I have add 3 divs those respective all values coming here each div has 2 input fields :
<script>
function updatebtn(el){
var id = $(el).attr('id');
$('input[type=text]:visible').each(function(){
console.log($(this).val());
})
})
</script>
Thanks
You need to use DOM traversal to find the input elements related to the button which was clicked. The simplest way to do that, given that you're already using jQuery, would be to use a delegated event handler for the dynamic button elements along with closest() and find().
It's also worth noting that your use of id attributes within the dynamic content is creating a lot more problems than it solves. I'd strongly suggest you remove them all and use common classes on all elements. That way you don't have the headache of having to manually update all the incremental ids when adding new content.
Try this:
jQuery(function($) {
var $traceContainer = $('#traces');
$('#add-button').click(function() {
var $div = $traceContainer.find('.trace:last').clone()
$div.find("input[name='t_x_axis']").val("");
$div.find("input[name='t_y_axis']").val("");
$traceContainer.append($div);
$div.find('span').text('Trace ' + ($div.index() + 1));
});
$traceContainer.on('click', '.update-trace', function() {
var $container = $(this).closest('table');
var xAxis = $container.find('input[name="t_x_axis"]').val();
var yAxis = $container.find('input[name="t_y_axis"]').val();
console.log(xAxis, yAxis);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button type="button" id="add-button">Add Element</button>
<div id="traces">
<div class="trace">
<h4><span>Trace 1</span></h4>
<form>
<table>
<tbody>
<tr>
<td><label>X Axis:</label></td>
<td><input type="text" name="t_x_axis" class="t_x_axis" size="50">
</td>
</tr>
<tr>
<td><label>Y Axis:</label></td>
<td><input type="text" name="t_y_axis" class="t_y_axis" size="50"></td>
<td><button type="button" name="update-button-trace" class="update-trace">Update </button></td>
</tr>
</tbody>
</table>
</form>
</div>
</div>
Finally, note that I added a div container around each .trace to make appending them and retrieving their index simpler. Also note that the form within each .trace seems redundant and can probably be removed.
You can use find value as $div.find('.t_y_axis').val()
$(document).ready(function(){
$('#add-botton').click(function(){
var $div = $('div[id^="trace-div"]:last');
var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;
var $trace1div = $div.clone(true).prop('id', 'trace-div'+num );
$trace1div.find('span').text('Trace ' + num);
$trace1div.find("input[name='t_x_axis']").attr("id", "x_axis_t"+num).val("");
$trace1div.find("input[name='t_y_axis']").attr("id", "y_axis_t"+num).val("");
$trace1div.find("button[name='update-button-trace']").attr("id", "update-button-trace"+num);
$div.after( $trace1div);
console.log( 'last t_y_axis => ' , $div.find('.t_y_axis').val());
console.log( 'last t_x_axis => ' , $div.find('.t_x_axis').val());
});
});
function updatebtn(el){
var id = $(el).attr('id');
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button type = "button" id = "add-botton" >Add Element </button>
<div id = "trace-div1" class = "trace">
<h4><span>Trace 1</span></h4>
<form>
<table>
<tbody>
<tr>
<td><label>X Axis: </label></td>
<td><input type="text" name="t_x_axis" class = "t_x_axis" id="x_axis_t1" size="50">
</td>
</tr>
<tr>
<td><label>Y Axis: </label></td>
<td><input type="text" name="t_y_axis" class = "t_y_axis" id="y_axis_t1" size="50"></td>
<td><button type = "button" name = "update-button-trace" class = "update-trace" id =
"update-botton-trace1" onclick="updatebtn(this)">Update </button></td>
</tr>
</tbody>
</table>
</form>
</div>
try using the following function.since both the input text boxes have their id you can use the same to get the value of the inputs.
Hope it helps!
function updatebtn(el) {
var x1 = document.getElementById('x_axis_t1');
var y1 = document.getElementById('y_axis_t1');
alert('x-axis is ',x1.value, ' and y-axis is', y1.value)
}
you need to develop your updatebtn().
function updatebtn(el){
var element = $(el),
parent_table = element.parentsUntil('table');
x_axis = parent_table.find('.t_x_axis').val();
y_axis = parent_table.find('.t_y_axis').val();
}

Hi there can someone please help me with this code:
So this is the blade
<table class="optionsForm" style="width:100%">
<thead>
<tr >
<th><button type="button" class="add">Add</button></th>
#for($c = 1; $c<=4; $c++)
<th id="column{{ $c}}">
<input type="text" name="columns[{{ $c }}]"
class="form-control" placeholder="Column {{ $c }} ">
</th> #endfor
<th><button type="button" style="width: 100px; height: 25px" class="addColumn">Add Column</button></th>
</tr>
</thead>
<tbody> #for($r = 1; $r<=4; $r++)
<tr class="prototype">
</tr> #endfor
</tbody>
</table>
and this one is the js code, I need to be able to add only one row, here it is adding 4 rows, I need first to be shown 4 rows, but than when I click add I need to be added only one row how can I achieve this can someone please help me with this thing I am stuck, thank you so much for any efforts.
$(document).ready(function () {
var id = 0;
// Add button functionality
$("table.optionsForm button.add").click(function () {
id++;
var master = $(this).parents("table.optionsForm");
// Get a new row based on the prototype row
var prot = master.find(".prototype").clone();
prot.attr("class", "")
prot.find(".id").attr("value", id);
master.find("tbody").append(prot);
});
// Remove button functionality
$("table.optionsForm button.remove").on("click", function () {
$(this).parents("tr").remove();
});
$("table.optionsForm button.addColumn").click(function () {
var $this = $(this), $table = $this.closest('table')
$('<th><input type="text" name="options" class="form-control" placeholder="Column"></th>').insertBefore($table.find('tr').first().find('th:last'))
var idx = $(this).closest('td').index() + 1;
$('<td><input type="radio" name="col' + idx + '[]" value="" /</td>').insertBefore($table.find('tr:gt(0)').find('td:last'))
});
});
The add button code is creating a collection of four elements with class "prototype" and then cloning four elements:
var prot = master.find(".prototype").clone()
To add a single element, try selecting the first DOM element from the collection and converting it to a JQuery object before applying clone:
var prot = $(master.find(".prototype")[0]).clone()
As a minimal test/demonstration case (not using blade)
var master = $("#master");
var prot = $(master.find(".prototype")[0]).clone();
master.append(prot);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="master">
<span class="prototype">proto 1</span><br>
<span class="prototype">proto 2</span><br>
<span class="prototype">proto 3</span><br>
<span class="prototype">proto 4</span><br>

I am using the find selector in jQuery by Id. It is behaving differently in case of a div vs tbody. This is a bigger problem - for the sake of clarity here is the reduced version of my original issue
HTML
<div id='iamdiv'>HELLO</div>
<table>
<tbody id='iamtbody'>
<tr><td>HELLO TOO</td></tr>
</tbody>
</table>
<input type='text' id='div'/>
<input type='text' id='tbody'/>
JS
$(document).ready(function() {
var allcontent = $($('body').html()); // I am deliberately doing this to input a HTML String.
var $divcontent = allcontent.find('#iamdiv');
$('#div').val($divcontent.html());
var $tbodycontent = allcontent.find('#iamtbody');
$('#tbody').val($tbodycontent.html());
});
Fiddle: https://jsfiddle.net/bragboy/Lt8nua10/1/
I want to display the raw html in the input text boxes, however only the tbody one is getting displayed and not the div. If I use a filter method instead of find - it works for div but not the tbody.
My objective is to have one consistent way of fetching for both tbody and div.
Two issues:
find looks for descendant elements, but #iamdiv is a top-level entry in your allcontents jQuery object.
You're duplicating the elements in the
var allcontent = $($('body').html());
line, which I'm fairly sure isn't what you want to do. (You've said that's on purpose, to simulate parsing HTML from elsewhere.)
You've said your goal is to use find in both use case (rather than using filter in one and find in the other). To do that, you need to have something else as the root of your allcontent.
You've also said that for some reason you can't change the
var allcontent = $($('body').html());
line, even just to
var allcontent = $("<body>").append($('body').html());
That's okay, you can still add a new root element by adding a line after it, like this:
allcontent = $("<body>").append(allcontent);
Live example:
$(document).ready(function() {
var allcontent = $($("body").html()); // You've said we can't change this
// The added line:
allcontent = $("<body>").append(allcontent);
var $divcontent = allcontent.find('#iamdiv');
$('#div').val($divcontent.html());
var $tbodycontent = allcontent.find('#iamtbody');
$('#tbody').val($tbodycontent.html());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id='iamdiv'>HELLO</div>
<table>
<tbody id='iamtbody'>
<tr><td>HELLO TOO</td></tr>
</tbody>
</table>
<input type='text' id='div'/>
<input type='text' id='tbody'/>
Use var allcontent = $('body'); instead of var allcontent = $($('body').html());
$(document).ready(function() {
var allcontent = $('body');
var $divcontent = allcontent.find('#iamdiv');
$('#div').val($divcontent.html());
var $tbodycontent = allcontent.find('#iamtbody');
$('#tbody').val($tbodycontent.html());
});
input {
width: 100%; /* just to show the whole content */
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id='iamdiv' class='somthing1'>
HELLO
</div>
<table>
<tbody id='iamtbody' class='somthing2'>
<tr>
<td>HELLO TOO</td>
</tr>
</tbody>
</table>
<input type='text' id='div' />
<br/>
<input type='text' id='tbody' />
After update in question :
You can use .closest() to achieve this. Because the cose that you picked when using $($(body).html()) has the div as on its node.
$(document).ready(function() {
var allcontent = $($('body').html());
var $divcontent = allcontent.closest('#iamdiv');
$('#div').val($divcontent.html());
var $tbodycontent = allcontent.find('#iamtbody');
$('#tbody').val($tbodycontent.html());
});
input {
width: 100%; /* just to show the whole content */
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id='iamdiv' class='somthing1'>
HELLO
</div>
<table>
<tbody id='iamtbody' class='somthing2'>
<tr>
<td>HELLO TOO</td>
</tr>
</tbody>
</table>
<input type='text' id='div' />
<br/>
<input type='text' id='tbody' />
I have gone through google and some of SO questions (such as this & this) as well but I didn't find the solution.

Because you are adding extra quotes in beginning and end in variable k. use:
var k = 'refNm_error' + (i+1);
You might need to reload the DOM after adding dynamic elements.
This link might help
Update, when you created your dynamic table rows for the table you didn't assign unique ids for input elements. So I updated the addRow handler:
$(document).on("click", ".addRowAux", function () {
to add unique input ids, like following:
$("#aux").append('<tr><td align="center">' + countrow + '</td><td align="center"><input type="text" name="ref_name[]" id="ref_name_' + countrow + '"/><span id="refNm_error_' + countrow + '">Please fill</span>...
and also I changed in the code:
<span id="removeRowaux">Remove</span>
to use class instead of an id:
<span class="removeRowaux">Remove</span>
Now the remove row handler listens to events from spans with class removeRowaux:
$(document).on('click', '.removeRowaux', function ()
Now the remove row functionality works and there are no spans with identical ids. So I don't think there was anything wrong with getElementById() in the code - it works fine :-)
Updated Fiddle
i created a button that allows you to clone a tree of elements. This is my code:
function add_party(number) {
var n = number.replace("party", "");
var newparty = document.getElementById("party"+n);
var div = document.createElement("div");
var con = document.getElementById("party1").innerHTML;
document.createElement("div");
div.id = 'party' + ++n;
div.innerHTML = con;
newparty.parentNode.insertBefore(div, newparty.nextSibling);
renumberDivs(div, n, "div","party");
}
This is my HTML:
<div id="party1">
<h1>Party 1</h1>
<table>
<tbody>
<tr>
<th>party name：</th>
<td><input type="text" name="name1" value="some name"></td>
</tr>
<tr>
<th>party time：</th>
<td><input type="text" name="time1" value="some time"></td>
</tr>
</tbody>
</table>
<input type="button" onclick="add_party(this.parentNode.id)" value="add party">
</div>
However, since each element has an unique ID or name the clone should not have the same IDs or names. Instead the new IDs and names should add up by 1. So the cloned tree should look like this:
<div id="party2">
<h1>Party 2</h1>
<table>
<tbody>
<tr>
<th>party name：</th>
<td><input type="text" name="name2" value=""></td>
</tr>
<tr>
<th>party time：</th>
<td><input type="text" name="time2" value=""></td>
</tr>
</tbody>
</table>
<input type="button" onclick="add_party(this.parentNode.id)" value="add party">
</div>
Also, the input values should be empty for the clone. How can i do it with javascript? (no jQuery please).
Thank you.
EDIT:
this code updates the count numbers so they always appear in order:
function renumberDivs(el, n, tagn, ass) {
while (el = el.nextSibling) {
if (el.tagName && el.tagName.toLowerCase() == tagn){
el.id = ass + ++n;
}
}
}
Generally, this solution is a 2-step process:
manipulate existing parties one by one from the last to the insert point.
insert new party to the insert point.
function add_party(divId) {
var party = document.getElementById(divId);
var newParty = party.cloneNode(true);
var allParties = document.querySelectorAll('div[id^="party"]');
var newId = parseInt(divId.replace('party', ''), 10) + 1;
for(var i = allParties.length-1; i > newId-2; i--) {
allParties[i].setAttribute('id', 'party' + (i+2));
allParties[i].querySelector('h1').innerHTML = 'Party ' + (i+2);
var partyInputs = allParties[i].querySelectorAll('input[type="text"]');
for(var j = 0; j < partyInputs.length; j++) {
var prefix = partyInputs[j].getAttribute("name").replace(/\d+/, "");
partyInputs[j].setAttribute("name", prefix + (i+2));
}
}
newParty.setAttribute('id', 'party' + newId);
newParty.querySelector('h1').innerHTML = 'Party ' + newId;
var inputs = newParty.querySelectorAll('input[type="text"]');
for(var i = 0; i < inputs.length; i++) {
var prefix = inputs[i].getAttribute("name").replace(/\d+/, "");
inputs[i].setAttribute("name", prefix + newId);
inputs[i].setAttribute("value", "");
inputs[i].value = "";
}
party.parentNode.insertBefore(newParty, party.nextSibling);
}
<div id="party1">
<h1>Party 1</h1>
<table>
<tbody>
<tr>
<th>party name：</th>
<td><input type="text" name="name1" value="some name"></td>
</tr>
<tr>
<th>party time：</th>
<td><input type="text" name="time1" value="some time"></td>
</tr>
</tbody>
</table>
<input type="button" onclick="add_party(this.parentNode.id)" value="add party">
</div>
you'd better attach event to element using addEventListener. I found it works fun. Please refer to DEMO..., but there is a question, for the new generated form, there is no event handler attached, so you should attach new event handler for new generated form. if you can use jQuery or some others, you can use function like Delegate that bind event handler automatically
I hope you can help me with a Javascript problem I'm having, I've been staring at this for days and I just can't figure it out!!
I've got a script that splits the value of an option dropdown and populates certain feilds with the splitted values.
Then I've got an 'Add Order Line' hyperlink to add a new row to a table, but I want the above feature to happen on any new line as well but nothing happens
I've recreated this in jsfiddle.
$(window).load(function(){
var selectEl = document.getElementById('part_selection');
selectEl.onchange = function () {
//var input1 = document.getElementsByName('PART_NO');
var input2 = document.getElementById('PART_DESCRIPTION');
var input3 = document.getElementById('PART_PRICE');
var input4 = document.getElementById('UNIT_MEAS');
var val = this.value;
var parts = val.split("_");
/*input1.value = parts[0];*/
input2.value = parts[1];
input3.value = parts[2];
input4.value = parts[3];
}
});
$(function(){
var counter = 1;
$('a.add-line').on('click',function()
{
counter ++;
$(this).prev('table.orderlinelist').find('tr').last().clone().find('input').val('').end().find('input.ORDER_LINE_NO').val(counter).end().appendTo('table.orderlinelist');
});
});
<table class="orderlinelist">

<td>Line</td>
<td>Part</td>
<td>Part Description</td>

Add Line
Can you point me in the right direction?
Cheers
These are steps you can take to do what you want:
first add class attributes to the input tags, instead of ID.
Use jQuery .on() to handle your dynamic event.
Use closest to find the current row.
then using jQuery find, find the inputs based on their class attributes.
And continue the rest of your code scenario.
I took these steps on your code like:
$(document).on("change", "table.orderlinelist .part_selection", function () {
var jrow = $(this).closest('tr');
var input2 = jrow.find('.PART_DESCRIPTION');
var input3 = jrow.find('.PART_PRICE');
var input4 = jrow.find('.UNIT_MEAS');
var val = this.value;
var parts = val.split("_");
input2.val(parts[1]);
input3.val(parts[2]);
input4.val(parts[3]);
});
This is your working DEMO
