I have a json file with some data and I am using a Js loop to load a jQuery template to iterate through and load a table made of 4 rows based on the data, so far I only get the last row. https://github.com/codepb/jquery-template
<script type="text/html" id="tableContent">
<tr>
<th>Key</th>
<th>Product</th>
<th>Bookings</th>
<th>%</th>
<th>Transactions</th>
</tr>
<tr>
<td data-content="">sth</td>
<td data-content="Product"></td>
<td data-content="Bookings"></td>
<td data-content="Percentage"></td>
<td data-content="Transactions"></td>
</tr>
</script>
function builTable(){
var table = "",
colors = ['col1', 'col2', 'col3', 'col4', 'col5', 'col6'];
for(i = 0; i< source.Products.length; i++){
$("table").loadTemplate($("#tableContent"),
{
Product: source.Products[i].Product,
Bookings: source.Products[i].Bookings,
Percentage: source.Products[i].Percentage,
Transaction: source.Products[i].Transaction
} );
$(document).ready(function(){
builTable();
});
<table border="1" cellpadding="2">
</table>
Is there something wrong inside the loop?

I think you just need to add an array because it loads the whole content just once and then overrides it again. But therefore you need to only include the data rows in the template and add the headings to the table (DEMO):
<script type="text/html" id="tableContent">
<tr>
<td data-content="">sth</td>
<td data-content="Product"></td>
<td data-content="Bookings"></td>
<td data-content="Percentage"></td>
<td data-content="Transactions"></td>
</tr>
</script>
Your table:
<table>
<thead>
<tr>
<th>Key</th>
<th>Product</th>
<th>Bookings</th>
<th>%</th>
<th>Transactions</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
And the js:
function builTable(){
$("tbody").loadTemplate($("#tableContent"), source.Products);
}

I have the following table
<table width="97%" border="1" class="queueList">
<thead>
<tr>
<th>Delete</th>
<th>Queue Name</th>
<th>Current queue length</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model.ImportQueues)
{
<tr id="watchRow">
<td id="DeleteButton">X</td>
<td id="QueueName", value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
}
</tbody>
how can I get the value of the element "QueueName" when "#DeleteRow" is clicked, using JQuery ?
So far I have
$("body").on("click", "#DeleteButton", function (event) {
var queueName = $(event.target).closest("div.queueList").find("#QueueName");
alert(queueName);
}
Use the data attribute to store the desired value on the button itself
<tr class="watchRow">
<td class="DeleteButton" data-queuename="#item.QueueName">X</td>
<td class="QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
then on click of TD (by the way, it should be a button)
$("body").on("click", ".DeleteButton", function() {
var queueName = $(this).data("queuename");
alert(queueName);
}
If you want to use this name on other buttuns also, like edit etc. then it is better to assign it to the whole row:
<tr class="watchRow" data-queuename="#item.QueueName">
<td class="DeleteButton">X</td>
<td class="QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
and read it like this:
$("body").on("click", ".DeleteButton", function() {
var queueName = $(this).closest('tr').data("queuename");
alert(queueName);
}
Without JQuery
<tr id="watchRow">
<td class="DeleteButton" onclick="deleteItem(#item.QueueName)">X</td>
<td value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
<script>
function deleteItem(item) {
alert(item)
}
</script>
With JQuery
<tr id="watchRow">
<td class="DeleteButton">X</td>
<td value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
<script>
$(".DeleteButton").on("click", function() {
alert($(this).next("td").html());
}
</script>
</script>
I have something like this:
<table id="thatTable" class="table toggle-circle">
<thead>
<tr>
<th>ID</th>
<th>FieldA</th>
<th data-hide="all">FieldB</th>
<th data-hide="all">FieldC</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<td colspan="4">
<div class="text-right">
<ul class="pagination"></ul>
</div>
</td>
</tr>
</tfoot>
</table>
Then a JS like this:
var fillThatTable = function (list) {
$.each(list, function (index, item) {
$('#thatTable tbody').append($('<tr>')
.append($('<td>').text(item.ID))
.append($('<td>').text(item.FieldA))
.append($('<td>').text(item.FieldB))
.append($('<td>').text(item.FieldC))
)
);
});
};
Everything works fine, the table gets the data and shows it all. Problem comes when I want to set footable() to that table, like so:
$(document).ready(function () {
fillThatTable();
$('#thatTable').footable();
});
And instead of getting something beautiful, I just receive an average filtered table, almost like I didn't put that $('#thatTable').footable(). I checked the JS are imported, they are. Is it maybe because the table doesn't have anything in the tbody? What am I missing?
Dream:
Reality:
I've updated PM's fiddle to make an easier use of FooTable: http://jsfiddle.net/0pb4x7h6/1
If your html changes to this:
<table id="thatTable" class="table toggle-circle">
<thead>
<tr>
<th data-name="ID">ID</th>
<th data-name="FieldA">FieldA</th>
<th data-name="FieldB" data-breakpoints="all">FieldB</th>
<th data-name="FieldC" data-breakpoints="all">FieldC</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<td colspan="4">
<div class="text-right">
<ul class="pagination"></ul>
</div>
</td>
</tr>
</tfoot>
</table>
Then you can simplify your script to this:
$(document).ready(function () {
var list = [
{"ID":"1","FieldA":"A1","FieldB":"B1","FieldC":"C1"},
{"ID":"2","FieldA":"A2","FieldB":"B2","FieldC":"C2"},
{"ID":"3","FieldA":"A3","FieldB":"B3","FieldC":"C3"}
];
// No need for this
//fillThatTable();
$('#thatTable').footable({
rows: list
});
});
Can anyone help me learn how to convert an HTML table into a dynamic Javascript table using the for loop? This is an example I found in my book and wanted to see how I could go about doing this.
Heading There is sections of the table that need to have the rows combined and he columns combined. I have been struggling with this for some time. Any help would be appreciated. I did not include the CSS portion of the code only the table.
<html>
<body>
<table class="table">
<tr>
<th colspan= "3" class= "MH">Conversion Tables</th>
</tr>
<tr>
<th rowspan="3" class="heading1">Meters to
<br />Feet</th>
<td>1 meter</td>
<td>3.28 feet</td>
</tr>
<tr class="difrow">
<td>50 meters</td>
<td>164.04 feet</td>
</tr>
<tr>
<td>100 meters</td>
<td>328.08 feet</td>
</tr>
<tr class="difrow">
<th rowspan="3" class="heading1">Kilometers to
<br />Miles</th>
<td>1 kilometer</td>
<td>0.62 miles</td>
</tr>
<tr>
<td>50 kilometers</td>
<td>31.07 miles</td>
</tr>
<tr class="difrow">
<td>100 kilometers</td>
<td>62.14 miles</td>
</tr>
</table>
</body>
</html>
you can add id attribute to table tag then call a javascript method on page load:
<table class="table" id="tableId">
function createRows(){
var items = "<tr><td></td></tr>...";
document.getElementById("tableId").innerHTML = items;
}
in javascript method you can use for to generate table rows.
For each element with the class the_name, I want to alert the value inside that element. So for the code below, it should alert three times. Once each for: "apples", "pears", and "plums".
Not sure what I am missing here.
var arr = $('.the_name');
for(var i = 0; i < arr.length; i++){
alert(arr[i].val());
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table id="datatable">
<thead>
<tr>
<th></th>
<th>Fruits</th>
</tr>
</thead>
<tbody>
<tr>
<td class="the_name">Apples</td>
<td class="the_count">3</td>
</tr>
<tr>
<td class="the_name">Pears</td>
<td class="the_count">2</td>
</tr>
<tr>
<td class="the_name">Plums</td>
<td class="the_count">5</td>
</tr>
<tr>
<td>Bananas</td>
<td>1</td>
</tr>
<tr>
<td>Oranges</td>
<td>2</td>
</tr>
</tbody>
</table>
By accessing the jQuery object by index you're retrieving the underlying DOMElement, not the jQuery object, and they do not have a val() method. Also note that you seems to be looking to retrieve the text of the element, not the value. As such, you should use each() to loop over the selected elements, using this to refer to the element of the current iteration. Try this:
$('.the_name').each(function() {
alert($(this).text());
});
Also note that for debugging purposes, console.log() should be used instead of alert().
$('.the_name').each(function() {
alert($(this).text());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table id="datatable">
<thead>
<tr>
<th></th>
<th>Fruits</th>
</tr>
</thead>
<tbody>
<tr>
<td class="the_name">Apples</td>
<td class="the_count">3</td>
</tr>
<tr>
<td class="the_name">Pears</td>
<td class="the_count">2</td>
</tr>
<tr>
<td class="the_name">Plums</td>
<td class="the_count">5</td>
</tr>
<tr>
<td>Bananas</td>
<td>1</td>
</tr>
<tr>
<td>Oranges</td>
<td>2</td>
</tr>
</tbody>
</table>
you need to use .text() instead of .val().
.val() works on input elements (or any element with a value attribute?) and .text() will not work on input elements. .val() gets the value of the input element -- regardless of type. .text() gets the innerText (not HTML) of all the matched elements:
.text()
The result is a string that contains
the combined text contents of all
matched elements. This method works on
both HTML and XML documents. Cannot be
used on input elements. For input
field text use the val attribute.
.val()
Get the content of the value attribute
of the first matched element
you need to use use $ to use jquery method .text().
var arr = $('.the_name');
for(var i = 0; i < arr.length; i++){
alert($(arr[i]).text());
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table id="datatable">
<thead>
<tr>
<th></th>
<th>Fruits</th>
</tr>
</thead>
<tbody>
<tr>
<td class="the_name">Apples</td>
<td class="the_count">3</td>
</tr>
<tr>
<td class="the_name">Pears</td>
<td class="the_count">2</td>
</tr>
<tr>
<td class="the_name">Plums</td>
<td class="the_count">5</td>
</tr>
<tr>
<td>Bananas</td>
<td>1</td>
</tr>
<tr>
<td>Oranges</td>
<td>2</td>
</tr>

The indexed values of a jQuery object are HTML elements, not jQuery objects.
You have to wrap them in a jQuery object before you can call jQuery methods on them:
var arr = $('.the_name');
for(var i = 0; i < arr.length; i++){
var html_element = arr[i];
var $html_element = $(html_element);
alert($html_element.val());
}
I've got a couple tables whose content should change based on clicking certain buttons (in this case, links). I've used this Javascript code elsewhere successfully, though with only one parameter in the switchid() function (there was only one table to mess around with). I keep researching examples of this and I seem to be passing the variables correctly, so what am I doing wrong? This code doesn't work on Chrome or IE:
Edit: Per the comments, I was able to whittle my javascript section down to a single, smaller function, that should do the same thing. I have made the change below. It still doesn't work, though.
I also changed my "array" and "x" variables to "JonArray" and "JonX" to avoid any chances of one of those being a reserved word.
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
var topTable = new Array('English','Spanish');
var bottomTable = new Array('Japanese','Italian');
function switchid(JonArray,JonX) {
for(var i=0;i<JonArray.length();i++) {
document.getElementById(JonX).style.display='none';
}
document.getElementById(JonX).style.display='table-row-group';
}
</script>
<table border='1'>

<tr><td>Odds</td><td>Evens</td></tr>

I made sure the function and variables were available regardless of when they are created.
I also gave your variables descriptive names, cleaned up and stored the table data in a single object.
JavaScript
window.switchid = function (table, language) {
var tables = {
'top': ['English', 'Spanish'],
'bottom': ['Japanese', 'Italian']
};
for (var i = 0; i < tables[table].length; i++) {
document.getElementById(tables[table][i]).style.display = 'none';
}
document.getElementById(language).style.display =
'table-row-group';
}
HTML
<table border='1'>
<thead>
<tr>
<td>Odds</td>
<td>Evens</td>
</tr>
</thead>
<tfoot>
<tr>
<td>English
</td>
<td>Spanish
</td>
</tr>
</tfoot>
<tbody id='English'>
<tr>
<td>One</td>
<td>Two</td>
</tr>
<tr>
<td>Three</td>
<td>Four</td>
</tr>
</tbody>
<tbody id='Spanish' style="display:none;">
<tr>
<td>Uno</td>
<td>Dos</td>
</tr>
<tr>
<td>Tres</td>
<td>Quatro</td>
</tr>
</tbody>
</table>
<br />
<table border='1'>
<thead>
<tr>
<td>Odds</td>
<td>Evens</td>
</tr>
</thead>
<tfoot>
<tr>
<td>Japanese

<td>Italian
</td>
</tr>
</tfoot>
<tbody id='Japanese'>
<tr>
<td>Ichi</td>
<td>Ni</td>
</tr>
<tr>
<td>San</td>
<td>Shi</td>
</tr>
</tbody>
<tbody id='Italian' style="display:none;">
<tr>
<td>Un</td>
<td>Due</td>
</tr>
<tr>
<td>Tre</td>
<td>Quattro</td>
</tr>
</tbody>
</table>
you have to change your javascript a little:
var tables=new Array();
tables['topTable'] = new Array('English','Spanish');
tables['bottomTable'] = new Array('Japanese','Italian');
function switchid(JonArray,JonX) {
//alert(JonArray);
var tmptable=tables[JonArray];
for(var i=0;i < tmptable.length;i++) {
document.getElementById(tmptable[i]).style.display='none';
}
document.getElementById(JonX).style.display='';
}
Some of these answers work, but I just caught the REAL answer via Chrome DevTools! In my 'for' loop I was using 'length()' instead of 'length'!!!
Why not to use CSS instead of looping through IDs?
