Below is my code but it does not work yet. What should I do to fix it?
See in particular function showtbl();
My real problem is in function showtbl(); which does not display the contents of the table.

My real problem is in function showtbl(); which does not display the contents of the table.
Please run the code. What should I do to fix it?
My real problem is in function showtbl(); which does not display the
contents of the table.
If you remove the irrelevant empty <tbody><tr></tr></tbody> it works :
http://jsfiddle.net/yujpozf9/1/
dataTables does not like multiple <tbody> elements, and certainly not <tbody> elements with an odd number of columns (like none).
Also move responsive: true out to where it belongs and remove the trailing ' - you seem to have a lot of focus on IE7, trailing quotes is a IE7-killer.
var table = $('#myTable').dataTable({
responsive: true,
"oSearch": {
//"sSearch": $.urlParam('apps')
}
});
have commented out $.urlParam since this is not the main issue, and I not fully understand what you are trying to do. Your code is one of the most peculiar uses of dataTables I have ever seen (no offense!) - try read about column rendering, I think you will be much happier doing it this way -> https://datatables.net/examples/advanced_init/column_render.html - the official examples in general.
Also, instead of using google drive, you can use the dataTables CDN - much easier to maintain and change versions. I have noticed you are using v1.10.2 :
<script type="text/javascript" src="//cdn.datatables.net/1.10.2/js/jquery.dataTables.min.js"></script>
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.2/css/jquery.dataTables.min.css"/>
As far as I remember, datatables plugin need well-formatted table to work properly. You need thead and tbody tags as it's specified in the doc (read it carefully : https://www.datatables.net/manual/installation). Once it's done you don't have to write all that code to filter and display what you want.

I'm parsing JSON feed from the blogger API but its throwing following error:
37:59 Uncaught TypeError: Cannot read property 'url' of undefined
Previously it was working fine, there weren't any issues but suddenly the error keeps coming up and nothing is displaying. I have looked for stackoverflow and followed this post as well but the error is not going away. Maybe blogger has changed their object nodes that i can't figure out.
Javascript Code:
<script type="text/javascript">
function mycallback(json) {
for (var i = 0; i < json.feed.entry.length; i++) {
for (var j = 0; j < json.feed.entry[i].link.length; j++) {
if (json.feed.entry[i].link[j].rel == 'alternate') {
var postUrl = json.feed.entry[i].link[j].href;
break;
}
}
var postTitle = json.feed.entry[i].title.$t;
var postAuthor = json.feed.entry[i].author[0].name.$t;
var postSummary = json.feed.entry[i].summary.$t;
var entryShort = postSummary.substring(0,400);
var entryEnd = entryShort.lastIndexOf(" ");
var postContent = entryShort.substring(0, entryEnd) + '...';
var postImage = json.feed.entry[i].media$thumbnail.url.replace('s72-c/','s640/');
var postTimestamp = json.feed.entry[i].published.$t;
var item = '<div class="col-md-3 mb-4 blogpost-main">';
var item = item + '<div class="card h-100">';
var item = item + '<img class="card-img-top" src="' + postImage + '"/>';
var item = item + '<div class="card-body">';
var item = item + '' + postTitle + '</h6>';
var item = item + '<p class="card-text text-muted"><i class="far fa-clock" style="color: #888"></i> <time class="timeago" datetime= '+ postTimestamp +'>' + postTimestamp + '</time></p>';
var item = item + '</div>';
var item = item + '</div>';
var item = item + '</div>';
//document.write(item);
document.getElementById("news").appendChild(item);
console.log(item);
}
}
</script>
<script src="https://www.wallpapersoverflow.com/feeds/posts/summary?orderby=published&max-results=4&alt=json-in-script&callback=mycallback"></script>
<div id="news"></div>
JsFiddle: https://jsfiddle.net/645pg9rz/
If you run console.log(json.feed.entry) in your fiddle, you'll see that there is no key called media$thumbnail in the returned objects. That is why your code is failing at var postImage = json.feed.entry[i].media$thumbnail.url.replace('s72-c/','s640/'); - it is trying to access the url property of an item that doesn't exist.
Perhaps the API used to use that key and no longer does, or there are just no thumbnails available in the entries you requested. I don't see a new key with an image file other than the Blogger logo.
Updated: the pictures you're trying to reach are not in the object that came to you. that's why you get the error. (json.feed.entry[i].media$thumbnail)
there are no pictures in the object that came to you. It's the only icon that comes. I put them.

I am displaying a table on the webpage as follows:
ID | Val | Num
ABC | Value1 | 1
ABC | Value1 | 0.8
CDB | Value 2 | 0.5
I want that if the cell value in Num column for that row is between 1 and 0.8, then the background color of the corresponding Val column's cell should be red, if between 0.7 to 0.5 then orange, and below it yellow.
I'm using DataTables
Below is my js code:
for (col_id = 0; col_id < csv_data[row_id].length; col_id++) {
if (col_id === 2) {
row_html += "<td>" + parseFloat(csv_data[row_id][col_id]) + "</td>";
}
else {
row_html += "<td>" + csv_data[row_id][col_id] + "</td>";
}
}
row_html += "</tr>";
$('#' + el + '-table tbody').append(row_html);
}
$('#' + el + '-table').DataTable(datatables_options);
I tried to add the background color to the cell using the style.backgroundColor but I don't think it's working. I added this inside the for loop:
if (col_id === 1) {
if (parseFloat(csv_data[row_id][2]) <= 1 && parseFloat(csv_data[row_id][2]) > 0.7)
{
row_html.style.backgroundColor = 'ec8e8e'
}
}
But it's not working. Could anybody tell me how to do it?? Thanks!
UPDATE:
My csvToHtml.js file:
var CsvToHtmlTable = CsvToHtmlTable || {};
CsvToHtmlTable = {

var el = options.element || "table-container";

var table_head = "<thead><tr>";
for (head_id = 0; head_id < csv_data[0].length; head_id++) {

You can append row_html with $(row_html) and apply css to that with your condition.
Here color will be based on your condition.
$('#' + el + '-table tbody').append($(row_html).css('background',color));
Check below sample to get more idea
$(document).ready(function() {
$('#example').dataTable();
var val = 0.1;
var row_html = "<tr>";
row_html += "<td>ADD</td><td>val 4</td><td>" + val + "</td>";
row_html += "</tr>";
var color = "red"; // can be hex value, #ededed
if (val > 0.7) {
color = "orange";
} else if (val < 0.4) {
color = "yellow";
}
$('#example').append($(row_html).css("background-color", color));
});

I'm trying to get and display the image and information of a clicked pokemon from pokemon API

$(document).ready(function(){

$("#pokemon").append("<img id=pokepic" + i + "

}
var clicked = false;
$("img").click(function(){
clicked = true;
console.log(this);
if(clicked){
$.get("http://pokeapi.co/api/v1/pokemon/" + i +"/", function(data){
var str = "";
str += "<h4>Types</h4>";
str += "<ul>";
var str2 = "";
str2 += "<h4>height</h4>";
str2 += "<ul>";
var str3 = "";
str3 += "<h4>weight</h4>";
str3 += "<ul>";
for(i = 0; i < data.types.length; i ++){
str += "<li>" + data.types[i].name + "</li>";
}
str2 += "<li>" + data.height + "</li>";
str3 += "<li>" + data.weight + "</li>";
str += "</ul>"
str2 += "</ul>"
str3 += "</ul>"
$("#chosen").html(str + str2 + str3); }, "json");
}
else{
clicked = false;
}
})
});
At the moment, the only information being brought up are for the first 3 pokemon in the list, not for the pokemon that was clicked. I need to find the information associated with the clicked pokemon, like a pokedex.
I included console.log to show that whichever image is clicked, the picture, and pokepic ID number associated with that image appear in the console. Instead what I need is for the image and stats associated with each image to appear in the div labeled chosen
Your click event uses the i variable defined in your for loop. Since the function inside the click is always called after the loop is done, i is always 152. You need to read the current pokemon from your click event:
$('img').on('click', function(e){
var pokemonId = e.target.id.split('pokepic')[1];
$.get("http://pokeapi.co/api/v1/pokemon/" + pokemonId +"/", function(data){
...
});
});
I have an application which returns a JSONObject. I am able to get data from JSON object using below code.

<body>
<form name="myform">

<table id="proctable">

</form>
</body>
</html>
The above html creates a table showing a list of the returned values. I also want to get rowIndex of hyperlink and pass value of column2 to function generateBPDInstance.
I am not so good at HTML and Jquery. Please suggest how can I get rowIndex for HTML table which is created through javascript.
Thanks in advance.
The simple way is :
change your table building to this
for (i = 0; i < obj.data.exposedItemsList.length; i++) {
ulink = "http://" + host + obj.data.exposedItemsList[i].startURL;
thtml = thtml + "" + obj.data.exposedItemsList[i].display + "" + ulink + "";
function my_function(e){
//e is the row index and when you call document.getLementById("proctable").rows[e]; this will give you the complete row.
}
--this is a simple way, and if you want traverse the tree and get , you always have parentnode or you can use jquery $(object).parent() to get the parent of hyperlink and traverse.
You problem is "pass value of column2 to function generateBPDInstance". Why not pass it already while generating the table?
for (i = 0; i < obj.data.exposedItemsList.length; i++) {
ulink = "http://" + host + obj.data.exposedItemsList[i].startURL;
thtml = thtml + "<tr><td><a onclick='my_function('" + ulink + "')' href='javascript:void(0)'>" + obj.data.exposedItemsList[i].display + "</a></td><td id='linkcell' class='hideMe'>" + ulink + "</td></tr>";
// ------------------------------------------------------^ pass the value
}
Add parameter to your function generateBPDInstance
function generateBPDInstance(ulink) {
//--------------------------^----
$.post(ulink, function (taskdata) {
var tobj = JSON.parse(taskdata);
alert(tobj.data.tasks[0].name);
alert(tobj.data.tasks[0].tkiid);
});
}
I've found dragtable http://www.danvk.org/wp/dragtable/ but I need a Jquery-based solution. May be I'm missing something?
The plugin jqGrid (latest versions at github repo) has a feature to re-order columns - the documentation is here. It does not appear to have drag/drop support for re-ordering columns however.
Here is a custom working sample of draggable table columns using only jQuery and jQuery UI sortable interaction.

This JavaScript does drag-and-drop on columns. As it doesn't uses any framework you can combine it easily with any other framework.
Why do you nee a jQuery based solution when you can have one without the need of a specific framework.
Another approach to reorder columns with Jquery UI Sortable:
http://jsfiddle.net/pg7wH/
Needs
jQuery (tested with 1.7.2 - 2.0)
jQuery UI (tested with 1.8.18 - 1.10.2)
HTML:
<button id="getSorting">Get sorting</button><input id="showSorting" />
<table id="table1">
<thead class="ui-state-default"></thead>
<tbody></tbody>
</table>
JS:
$(function() {
var $table1 = $('#table1');
var $table1Thead = $table1.find('thead');
var $table1Tbody = $table1.find('tbody');
var startPos;
var oldPos;
// populate fake data
var maxCols = 10;
var maxRows = 50;
for (var i = 1; i <= maxCols; i++) {
$table1Thead.append('<th sort="' + i + '" id="column[' + i + ']">column ' + i + '</th>');
}
var rowHtml;
for (var x = 1; x <= maxRows; x++) {
rowHtml = '<tr>';
for (var i = 1; i <= maxCols; i++) {
//rowHtml += '<td>' + i + ' - ' + x + '</td>';
rowHtml += '<td>col ' + i + '</td>';
}
rowHtml += '</tr>';
$table1Tbody.append(rowHtml);
}
// Show sorting
$("button#getSorting").click(function() {
$('#showSorting').val($table1Thead.sortable('toArray', { attribute: "sort" } ))
console.log($table1Thead.sortable('toArray', { attribute: "sort" } ))
})
// The sorting
$table1Thead.sortable({
axis: "x" ,
items: 'th',
containment: 'parent',
cursor: 'move',
helper: 'clone',
distance: 5,
opacity: 0.5,
placeholder: 'ui-state-highlight',
start: function(event, ui) {
startPos = $table1Thead.find('th').index(ui.item);
oldPos = startPos;
},
change: function(event, ui) {
// Get position of the placeholder
var newPos = $table1Thead.find('th').index($table1Thead.find('th.ui-state-highlight'));
// If the position is right of the original position, substract it by one in cause of the hidden th
if(newPos>startPos)newPos--;
// move all the row elements
//console.log('Move: 'oldPos+' -> '+newPos);
$table1Tbody.find('tr').find('td:eq(' + oldPos + ')').each(function() {
var tdElement = $(this);
var tdElementParent = tdElement.parent();
if(newPos>oldPos)// Move it the right
tdElementParent.find('td:eq(' + newPos + ')').after(tdElement);
else// Move it the left
tdElementParent.find('td:eq(' + newPos + ')').before(tdElement);
});
oldPos = newPos;
}
});
});
