Get the ID in row that has radio button checked [duplicate]

This question already has answers here:
Getting values of elements in same row when button is clicked, one button per row
(2 answers)
Closed last year.
I have this function which creates a table in a modal popup and the table gets populated from data in an array passed in from an ajax call. Now on the click of a button in the modal popup I need to get the value of item.TimedPathwayID that has its radio button checked and add it to a hidden field.
function PopulateTimedPathwaysTable(tblData) {
var tbody = $('#tblTimedPathways tbody');
$.map(tblData.d, function (item) {
tr = $('<tr></tr>');
tr.append('<td class="pathwayID">' + item.TimedPathwayID + '</td>');
tr.append('<td>' + item.TimedPathwayName + '</td>');
tr.append('<td><input type="radio" class="radioSelection" name="timedPathwaySelection"" />');
tbody.append(tr);
});
$('input[name=timedPathwaySelection]:first').attr('checked', true);}
}
I've been fiddling with this kind of thing but with no joy and the radio button in the first row is checked by default so this can't really be tied to a click event if a user just accepts the default without clicking. So how can I do it please?
$('body').on('click', '.radioSelection', function () {
var $tbl = $('#tblTimedPathways tbody');
var $dataRow = $tbl.closest('tr');
var id = $dataRow.find('td').eq(0).html();
});

.closest goes up the html tree, so tbody.closest(tr) is unlikely to be what you want.
you need to then go back down to the cell that contains the data you want.
let $this = $(this); //this is the radio button
let id = $this.closest("tr").find("td.pathwayID").text();
I would also echo that I would generally add the id as an attribute to the row to remove the necessity of the find later.
//sample data
let data = {
d: [{
TimedPathwayID: 1,
TimedPathwayName: "test"
},
{
TimedPathwayID: 2,
TimedPathwayName: "test"
},
{
TimedPathwayID: 3,
TimedPathwayName: "test"
}
]
};
function PopulateTimedPathwaysTable(tblData) {
var tbody = $('#tblTimedPathways tbody');
$.map(tblData.d, function(item) {
tr = $('<tr></tr>');
tr.append('<td class="pathwayID">' + item.TimedPathwayID + '</td>');
tr.append('<td>' + item.TimedPathwayName + '</td>');
tr.append('<td><input type="radio" class="radioSelection" name="timedPathwaySelection"" />');
tbody.append(tr);
});
$('input[name=timedPathwaySelection]:first').attr('checked', true);
}
//populate it
PopulateTimedPathwaysTable(data);
$('body').on('click', '.radioSelection', function () {
let $this = $(this); //this is the radio button
//console.log($this);
let id = $this.closest("tr").find("td.pathwayID").text();
console.log(id);
});

How to execute local stored value by search function afther page reload / refresh

I use the following form and script to let users filter a td table on the input they give in. It filters the rows of the table and only shows the rows corresponding to their given value. They can update the rows that they are seeing, after they do this the page refreshes/reloads to refresh the table. After the page is refreshed/reloaded the search filter shows all rows again. I am searching for a way to keep the rows that they had before the update event happend based on their filter input. In other words, as if the refresh never happend.
Search form;
...
<p align='left' style="display:inline">
<table class="userprof" align='left'>
<tr>
<td class="footer">Filter:
<input type="text" id="myInput" name="filter" style="color:black !important;" placeholder="Filter table" onkeyup='saveValue(this);' />
</td>
</tr>
</table>
</p>
...
I use the folowing script to save their input as localstorage.
...
document.getElementById("myInput").value = getSavedValue("myInput"); // set the value to this input
/* Here you can add more inputs to set value. if it's saved */
//Save the value function - save it to localStorage as (ID, VALUE)
function saveValue(e) {
var id = e.id; // get the sender's id to save it .
var val = e.value; // get the value.
localStorage.setItem(id, val); // Every time user writing something, the localStorage's value will override .
}
//get the saved value function - return the value of "v" from localStorage.
function getSavedValue(v) {
if (!localStorage.getItem(v)) {
return ""; // You can change this to your defualt value.
}
return localStorage.getItem(v);
}
...
I use the following script to filter the table rows
...
function filterTable(event) {
var filter = event.target.value.toUpperCase();
var rows = document.querySelector("#myTable tbody").rows;
for (var i = 0; i < rows.length; i++) {
var nameCol = rows[i].cells[1].textContent.toUpperCase();
var rankCol = rows[i].cells[2].textContent.toUpperCase();
var rankerCol = rows[i].cells[5].textContent.toUpperCase();
var typeCol = rows[i].cells[6].textContent.toUpperCase();
var emailCol = rows[i].cells[3].textContent.toUpperCase();
if (nameCol.indexOf(filter) > -1 || rankCol.indexOf(filter) > -1 || rankerCol.indexOf(filter) > -1 || typeCol.indexOf(filter) > -1 || emailCol.indexOf(filter) > -1) {
rows[i].style.display = "";
} else {
rows[i].style.display = "none";
}
}
}
document.querySelector('#myInput').addEventListener('keyup', filterTable, false);
...

You are almost there and only need minor modifications to make this happen.
I'd suggest that you change your flow up a bit.
First remove the onkeyup inline listener from your HTML. You are currently listening for that event 3 times on 1 element which seems overkill.
...
<p align='left' style="display:inline">
<table class="userprof" align='left'>
<tr>
<td class="footer">Filter:
<input type="text" id="myInput" name="filter" style="color:black !important;" placeholder="Filter table" />
</td>
</tr>
</table>
</p>
...
Then modify the filterTable to accept just a value, not an event object. This way you can call filterTable at any time and inject a value into it. And it allows you to call it immediately with the stored value when the page loads so that your initial filter will be set (or not if there is nothing stored).
Now listen for the keyup event with only a single listener which will both pass the value of the event to filterTable and the event itself to saveValue so that are both filtering and saving.
// Store the input in a variable for reference.
var myInput = document.getElementById("myInput");
var savedValue = getSavedValue("myInput");
// Immediately filter the table and set the input value.
filterTable(savedValue);
myInput.value = savedValue;
//Save the value function - save it to localStorage as (ID, VALUE)
function saveValue(e) {
var id = e.id; // get the sender's id to save it .
var val = e.value; // get the value.
localStorage.setItem(id, val); // Every time user writing something, the localStorage's value will override .
}
//get the saved value function - return the value of "v" from localStorage.
function getSavedValue(v) {
if (!localStorage.getItem(v)) {
return ""; // You can change this to your default value.
}
return localStorage.getItem(v);
}
function filterTable(value) {
console.log(value);
var filter = value.toUpperCase();
var rows = document.querySelector("#myTable tbody").rows;
for (var i = 0; i < rows.length; i++) {
var nameCol = rows[i].cells[1].textContent.toUpperCase();
var rankCol = rows[i].cells[2].textContent.toUpperCase();
var rankerCol = rows[i].cells[5].textContent.toUpperCase();
var typeCol = rows[i].cells[6].textContent.toUpperCase();
var emailCol = rows[i].cells[3].textContent.toUpperCase();
if (nameCol.indexOf(filter) > -1 || rankCol.indexOf(filter) > -1 || rankerCol.indexOf(filter) > -1 || typeCol.indexOf(filter) > -1 || emailCol.indexOf(filter) > -1) {
rows[i].style.display = "";
} else {
rows[i].style.display = "none";
}
}
}
myInput.addEventListener('keyup', function(event) {
var value = event.target.value;
saveValue(event);
filterTable(value);
});

How to get value of text box embeded in cell

I have the following code
<tr val='question'>
<td>
<input style='width: 500px' type='text' placeholder='Q.Enter your question here for radio button? '>
</tr>
How can i find the value of input box embedded in cell .
function saveUserDefQues(){
var table=document.getElementById("QuestionList");
var surveyquestionform=document.forms[0];
var count=$('#QuestionList tr').length
for (var i = 0; i<count; i++) {
var row = table.rows[i];
if(row.getAttribute('val')==='question')
{
var Cells = row.getElementsByTagName("td");;
}
}
}

document.querySelector('tr[val] > td > input').value;
Array.from(document.querySelectorAll('tr[val] > td > input')).forEach(function(entry, index, entries)
{
entry.value; // you may store the value OR process with it AS you see fit
});

Since you are using Jquery this can be done this way.
replace this line of code
var Cells = row.getElementsByTagName("td");
with
var Cells = $(row).find('td');
var inputValue = Cell.find('input').val(); // gives you value of input
Code Refactoring recommended
I would like to refactor your code as below
HTML
<tr data-val='question'> // use data-* attribute to add custom attributes into tags
<td>
<input style='width: 500px' type='text' placeholder='Q.Enter your question here for radio button? '>
</td> // close your td
</tr>
Script
function saveUserDefQues(){
var surveyquestionform = document.forms[0]; // not sure what this is for, so ill leave it as is.
$('#QuestionList tr[data-val="question"]').each(function(){ //loop all tr's which has the data-val set to question
var inputValue = $(this).find('td input').val(); //get the value of input
console.log(inputValue);
});
}

$("tr[val='question'] > td > input").val()
But first you need to write a valid HTML. </td> closing tag is missing. Also you need to put this tr in a <table>.

See this Plunker
function getResult(){
$( "tr" ).each(function( index ) {
console.log($(this).find('input').attr('placeholder') );
});
}

Add input text into html table td when double clicked

I have an html table with rows, in one of the cells I want to be able to insert an input text inside the cell whenever it is double clicked, and when this input is onblured I want to remove it and see it's value inside the td.
This is my code:
<td dir='ltr' id='test1' class='tLine' nowrap ondblclick='addInput(this);'>sdadfew</td>
function addInput(xxx) {
var id = xxx.id;
var value = document.getElementById(id).innerHTML;
document.getElementById(id).innerHTML = "<input type='text' id='input"+id +"' value='"+value+"' onblur='closeInput("+id+")'/>";
document.getElementById("input"+id).focus();
}
function closeInput(id) {
var value = document.getElementById('input'+id).value;
document.getElementById(id).innerHTML = value;
}
The problem is when I double click the input I get the text of the input inside of it.
How can I prevent this from happening? How can I resolve this issue?
UPDATE:
Inside the input I see this text:
<input type='text' id='input"+id +"' value='"+value+"' onblur='closeInput("+id+")'/>

Sorry for misunderstanding, this is the pure javascript version
javascript code
function closeInput(elm) {
var td = elm.parentNode;
var value = elm.value;
td.removeChild(elm);
td.innerHTML = value;
}
function addInput(elm) {
if (elm.getElementsByTagName('input').length > 0) return;
var value = elm.innerHTML;
elm.innerHTML = '';
var input = document.createElement('input');
input.setAttribute('type', 'text');
input.setAttribute('value', value);
input.setAttribute('onBlur', 'closeInput(this)');
elm.appendChild(input);
input.focus();
}
html code
<table>
<tr>
<td dir="ltr" id="test1" class="tLine" nowrap ondblclick="addInput(this)">sdadfew</td>
</tr>
</table>
jquery version still at http://jsfiddle.net/ZLmgZ/

Please have a look at this link
I have added some code on your function.
function addInput(xxx) {
xxx.setAttribute("ondblclick","return false");
var id = xxx.id;
var value = document.getElementById(id).innerHTML;
document.getElementById(id).innerHTML = "<input type='text' id='input"+id +"' value='"+value+"' onblur='closeInput("+id+")'/>";
document.getElementById("input"+id).focus();
}
Let me know if its work for you.

trying to get values from a HTML form?

I have a HTML form where i dynamically create elements and set its name , value attributes .
when i tried to access the value say document .formname.nameoftheelement.value then i get the error that value is undefined.
Then i tried to use the following function to access the values .it returns the input elements as 4 but value as null when i it already has predefined value .
function returnTheStoredValues(getTableName) {
//Array arrList = new Array(20);
var tableName = document.getElementById (getTableName);
console.log("The table name" + tableName);
if (tableName) {
var inputs = tableName.getElementsByTagName ('td');
console.log("the inputs are " + inputs.length);
if (inputs) {
console.log("inputs not equal to null")
for (var i = 0; i < inputs.length; ++i) {
console.log("the value in phones table are " + inputs[i].value);
//arrList[i] = inputs[i].value;
}
}
}
//return arrList;
}
The html code is
Phone
<table id="email_table">
<tr>
<td><h3>Email</h3></td>
<td><input value="+" type="submit" onClick="checkTheEmailButtonClicked()"></td>
</tr>
</table>
<table>
<tbody>
<tr>
<td><input type="submit" value ="Save" onclick="getData();"/></td>
<td><input type="submit" value = "Cancel"/></td>
</tr>
</tbody>
</table>
Appreciate all your help .

You seem to want the values of the input elements, so:
function returnTheStoredValues(getTableName) {
var arrList = [];
var table = document.getElementById(getTableName);
var inputs = table.getElementsByTagName('input');
for (var i=0, iLen=inputs.length; i<iLen; i++) {
arrList[i] = inputs[i].value;
}
return arrList;
}

Because you're getting the TD's and not the INPUT's?
var inputs = tableName.getElementsByTagName('td');
Should be
var inputs = tableName.getElementsByTagName('input');
By the way, if you use a Javascript framework, your code will be happier.

You really need to look into using jQuery for accessing elements through JavaScript.
You could then re-write your function to the following:
function returnTheStoredValues(getTableName) {
return $("#email_table input").map(function() {
return $(this).val();
}).get();
}
