Develop Reference

Copy content from <td> into a text box using jQuery

With the code below, I don't seem to be able to just set the textbox to the value of an TD element. What I need to achieve is to populate Enter Refund Amount box with the already present value of Grand Total field above. Nothing else is needed except copying the content from one element to the other.
window.onload = function() {
var src = document.getElementById("grand_total").innerHTML;
dst = document.getElementById("refund_amount").innerHTML;
src.addEventListener('#refund_amount', function() {
dst = src;
});
};

Firstly, #refund_amount isn't a valid event name. Given the context of the code and your goal I would assume that should be click instead. You also need to bind the event handler on the Element reference, not the a string variable containing its innerHTML value. In addition, to set the value of an input element you need to use the value property of the Element directly. Try this:
var src = document.getElementById("grand_total");
var dst = document.getElementById("refund_amount");
src.addEventListener('click', function() {
dst.value = src.textContent;
});
<table>
<tbody>
<tr>
<td>Grand total:</td>
<td id="grand_total">26.58</td>
</tr>
<tr>
<td>Refund amount:</td>
<td><input type="text" id="refund_amount" /></td>
</tr>
</tbody>
</table>

jQuery: Cannot access text box value using .val()

I'm building a dynamic table that users can add to, delete from, or edit. I have the following:
$(document).on('click', '.edit_rule', function() {
// editable text boxes for name and description
$(this).closest("tr").find("td:nth-child(2), td:nth-child(3)").each(function() {
var html = $(this).html();
var input = $('<input type="text" />');
input.val(html);
$(this).html(input);
});
// replace Edit and Delete with Save and Cancel
$(".edit_rule").replaceWith("<input id='Button' type='button' value='Save' class='sav$
$(".delete_rule").replaceWith("<input id='Button' type='button' value='Cancel' class=$
});
Which all works fine. But, when I try to access the new values in the next boxes, the value comes up blank. I was trying to use .val() and now am trying .text() as follows:
$(document).on('click', '.save_edit', function() {
var $row = $(this).closest("tr");
var $name = $row.find("td:nth-child(2)").find('input');
console.log($name.text()); // prints empty string
});
I'm fairly new to Javascript, so is there some weird scope thing I'm not understanding that prevents the value from being accessed in a separate function? Is there another way to do it?
EDIT: Here is the corresponding HTML
<div id="customperms_table_container" style="height:655px;">
<table id="customperms_table_form" cellpadding="10" cellspacing="$
<caption></caption>
<thead>
<tr>
<th>#</th>
<th>Role Name</th>
<th>Description</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
</div>

Issue is td has no value.
Solution is use .text() or .html() to get its text or html
Based on comment:
Your selector should be:
var $name = $row.find("td:nth-child(2)").find('input')// add class or id if there other inputs

Sorry about broken html, but combo of guradio and Haze fixed it.
var $name = $row.find("td:nth-child(3)");
console.log($name.val()); // <-- prints correct value

Using .find() and .each() in JS/Jquery

I've a PHP file which is a view (so mainly HTML) composed of several tables.
When the user click on one of the button, I want that the variables that are into my cells (and into the correct table) are sent to a Table in my Database.
To do this i'll use AJAX later, but at the moment i've a problem using JS/Jquery.
So I did something like this :
$('.boutton').click(function(){
$(?).find('td input').each(function(){
console.log($(this));
console.log($(this).val());
var iValue = $(this).val();
var sAllId = $(this).attr('id');
var sName = $(this).attr('name')
});
});
My table and buttons are into a div which has as id "table" + the number of the table.
I don't know what to do since I want this to work on every table, and on every button. It has to select only the td input that is into the table where the button was clicked.
My HTML is into a variable $sHtml since everything in this table are made of datas (in my DB) but it should be something like this :
<table id = "domaine-1-south">
<tr>
<th>BlaBla</th> // Several times
</tr>
<tr>
<td>Blabla</td>
<td><input id = "1#1#1#" name="high"></td>
<td><input id = "1#1#1#" name="mid"></td>
<td><input id = "1#1#1#" name="low"></td>
</tr>
<tr>
<td>Blabla</td>
<td><input id = "1#1#2#" name="high"></td>
<td><input id = "1#1#2#" name="mid"></td>
<td><input id = "1#1#2#" name="low"></td>
</tr>
For the id 1#1#1# the last 1 is for the number of the line and the second one is for in which table I'm.

You could use "start with" selector ^= to select all tables that have an id start with table :
$('[id^="table"]').find('td input').each(function(){
But in your OP you want to select the specific table related with the clicked button .boutton, so i guess that you have this button inside the table so you could select the current table using :
$(this).closest('table[id^="table"]').find('td input').each(function(){
Hope this helps.

Next <a> tag in table

I have a table that look like that :
<table>
<tbody>
<tr>
<td>
<a id="firstTAG" class="jp-play-me" data="foo"></a>
</td>
</tr>
<tr>
<td>
<a id="secondTAG" class="jp-play-me" data="bar"></a>
</td>
</tr>
<tr>
<td>
<a id="thirdTAG" class="jp-play-me" data="foobar"></a>
</td>
</tr>
</tbody>
</table>
And a javascript/jQuery function :
function getnextmedia(current) {
var res = current.split("/");
rowId = "#" + res[5];
$(".jp-play-me").each(function() {
if (this.id == rowId) {
alert(this.data);
alert($(this).next(".jp-play-me").attr("data"));
}
});
}
rowid is an id Im looking for in the table. I use the class jp-play-me to find all <a> tags and then compare id to get the good <a> tag. That works fine.
The next step is to get the following <a> tag in the table so the function can read the data attribute.
For exemple, if rowId is equal to secondTAG then I need to get the value foobar, which is the value of the following data <a> tag attribute.
I tried to use the next() method but I guess I do it the wrong way.
Let me know if you need more informations.

It's not working because the .next() method returns the immediately following sibling element. Since the anchor elements are not siblings, nothing is returned.
In order to get the anchor element in the next tr element, you would need to select the closest tr, then find the anchor element in the next tr:
$(this).closest('tr').next().find('.jp-play-me').attr("data");
$(".jp-play-me").each(function() {
if (this.id == rowId) {
// Next <a>
$(this).closest('tr').next().find('.jp-play-me').attr("data");
}
});

How to fetch the dynamically created element by its ID in jQuery

Initially adding the element statically like below:
<td valign="top" id="description_div">
*<table class="des_box" id="comment_div">
<tr><td class="head" id=file_comments> The function comments </td></tr>
<tr><td class="comment" id="test_point_comment_info"></td></tr>
</table>*
</td>
Dynamically adding the element as below :
$("#description_div").append(
'<table class="des_box1" id=comment_div><tr><td class="head" id=file_comments> The function comments </td></tr><tr><td class="comment" id=test_point_comment_info_' + id + '></td></tr> </table>')
Now, when I try to fetch the element by its id (that is by "comment_div") ... I am not able to retrieve the dynamically created element. But able to fetch the static element by using $("#comment_div")
I am trying to do following on the element :
$("#comment_div").show();
tried .live() ....but was not able to fetch the dynamic element.
$("#comment_div").live().show();
check box code :
<li><input type="checkbox" name="comment" />Comment</li>
actual functions where am trying to fetch the element:
$("#checkbox_div input:checkbox").click(function() {
var division = "#" + $(this).attr('name') + "_div";
$(division).show();
}
function SetCheckboxes(checkbox_data) {
//SetCookie('pre_checkbox', "1111111111111111")
var checkbox_data = GetCookie('pre_checkbox');
if (checkbox_data == null) {
SetCookie('pre_checkbox', "1111111111111111")
checkbox_data = GetCookie('pre_checkbox');
}
checkbox_array = new Array("owner", "test_time", "bp", "single_use", "num_of_test", "pause", "clearall", "clearclass", "clearmax", "closeall", "qeinbat", "m_lint","geck","header","comment","feature");
for ( i = 0; i < checkbox_data.length; i++) {
var checkbox_name = checkbox_array[i];
var value = checkbox_data[i];
var division = "#" + checkbox_name + "_div";
if (checkbox_name=="geck" || checkbox_name=="header" || checkbox_name== "comment" || checkbox_name=="feature"){
console.log("entering_loop_as_expected")
if (value == "1") {
//alert("1");
$("#checkbox_div input[name='" + checkbox_name + "']").attr("checked", "checked");
$(division).show();
} else {
$(division).hide();
}
continue;
}
Please help me out on this.

.live() is what you wanted but it has been depreciated, you now need to use .on()
$(document).on("click", "#checkbox_div input:checkbox", function(){
//Your code here.
});
Using document for your selector with .on will allow you to bind events to dynamically created elements. This is the only way I've found to do it when the DOM elements don't exist prior to execution.
I do this in a dynamically created table that is sort-able and works great.
EDIT:
Here is an example. Click the button to add a div then click the div to get it's contents.
http://jsfiddle.net/FEzcC/1/

You missed the quotes, also ensure you try to access them before they are added to DOM, e.g they will not be available on DOM ready if they are added on some button click. I think you forgot to give value of id, I have made a live demo.
Live Demo
$("#checkbox_div input:checkbox").click(function() {
var division = "#" + $(this).attr('name') + "_div";
$(division).show();
});
id=1;
$("#description_div").append('<table class="des_box1" id="comment_div"><tr><td class="head" id="file_comments"> The function comments </td></tr><tr><td class="comment" id="test_point_comment_info_' + id + '"></td></tr> </table>');
Edit based on comments and fiddle being provided.
You have few problems with html in the demo
Your html starts with td instead of table
You do not enclose the ids with quotes
You are assigning same id to more then one element, instead assign a
common class and use that.
Live Demo, Problem here are not dynamic element but the wrong HTML / Script
Html
<table>
<tr>
<td valign="top" id="description_div">
<table class="des_box" id="comment_div1">
<tr>
<td class="head" id="file_comments">The function commentszz</td>
</tr>
<tr>
<td class="comment" id="test_point_comment_info"></td>
</tr>
</table>
</td>
</tr>
</table>
<div id="checkbox_div">
<input type="checkbox" name="des" />Comment
</div>
Javascript
$("#description_div").append(
'<table class="des_box" id="comment_div2"><tr><td class="head" id=file_comments> The function comments </td></tr><tr><td class="comment" id=test_point_comment_info_' + 'id' + '></td></tr> </table>');
$(document).on("click", "#checkbox_div input:checkbox", function () {
var division = "." + $(this).attr('name') + "_box";
$(division).show();
});
If you have to use same id for more than one element with is wrong you can use attribute selector. First correct the html by enclosing td within tr and table tag.
Live Demo
$(document).on("click", "#checkbox_div input:checkbox", function(){
var division = "[id=" + $(this).attr('name') + "_div]";
$(division).show();
});

What is id value in + id +, id is undefined in current context. I have put it in single quote and its working fine.
Update: You are using same id comment_div for static and dynamic content, id should be unique in DOM. Use class instead of id for multiple elements
