I have this JSON which generates a table :
function show(json)
{
var content = '<table id = "myTable" border = 1>';
var counter;
for(counter = 0; counter < json.length ; counter++)
{
content += '<tr><td class = "topics">' + json[counter]['topic_name'] + '</td>''</tr>';
}
content += '</table>';
$('#table_here').append(content);
}
I call it two times :
1st. here :
$(document).ready(function(){
$.getJSON("admin.php", show);
Second when I add something on the table:
When I add something, the new table appears below the old one, I want to lose the old one and see only the new one. How can I do it?
try to change
$('#table_here').append(content);
into
$('#table_here').html(content);
this will replace the entire content of #table_here element

As the code below shows, I am appending a table with some table rows containing table data. The table data is getting appended with excel formula inside. How can I change the count variable inside td.class after it was appended in table upon click event or something similar.
I Want to update td.excel count attribute with onclick event
.append("<td class="
excel " x:num x:fmla=\"=SUM(H" + count + " *I" + count + ")
$("#example").on("click", "button", function() {
$(this).closest("tr").remove();
count--;
var i = 10;
for (i = 10; i < count; i++) {
let div1 = document.getElementsByClassName("excel");
var attribute = div1.SetAttribute(count, count);
}
}
Your problem is not clear. But what I've got from your question is that you want to dynamically append to . But you end up with excel formula getting inside it.
So, according to me when you want to insert something dynamically then you should use `` these quotes instead of '' and "". eg :-
var i = 1;
.append(`<td class="hello${i}"></td>`)
I'm kinda lost in figuring out the logic for javascript.
Currently, I'm extracting every element and pushing them into an array.
I'm having a hard time when I want to access the object element.
This is the data in the text file:
1#1#test#Tombstone#8#Yes
2#3#test2#Tombstone3#81#Yes
When I access the first array rowCells[0] . It returns me
1
2
which is the first column itself.
I was hoping for it to return the first row. The intended functionality is as follows:
1- Push everything to an array
2- Giving element key like first column is no,type,header,content,score
3- Search all the row based on the element key such as type=2
4- Search based on the type and no, then show the content.
Any suggestions?
Thanks in advance.
<script type="text/javascript"
src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script>
$.ajax({
url: 'content.txt',
dataType: 'text',
}).done(successFunction);
function successFunction(data) {
var allRows = data.split(/\r?\n|\r/);
var table = '<table>';
for (var singleRow = 0; singleRow < allRows.length; singleRow++) {
var rowCells = allRows[singleRow].split('#');
//table += rowCells.toString();
table += '<br>';
var first_word = rowCells;
table += first_word;
}
$('body').append(table);
}
</script>
I would just use split, reduce, split, and join to build the table.
var str = `1#1#test#Tombstone#8#Yes
2#3#test2#Tombstone3#81#Yes`
var rows = str.split(/\n/g).reduce( function (str, row) {
return str + "<tr><td>" + row.split(/#/g).join("</td><td>") + "</td></tr>";
}, "")
var table = "<table><tbody>" + rows + "</tbody></table>"
$("#out").append(table)
td { border: 1px solid black; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="out"></div>
I am making a program, and I'm wondering why all I see on my html page is the form, but only a single . where the bulleted list for an unordered list should be. I input the user input in the fields, but it doesn't show me the data in the fields, like it's supposed to, when I click submit. Here's the code.
function getFormElements() {
var gather_form_elements = new Array(
$("#first_name").val(),
$("#last_name").val(),
$("email").val(),
$("#phone_number").val()
);
displayValues(gather_form_elements);
}
function displayValues(gather_form_elements) {
for(i=0; i<gather_form_elements.length; i++)
{
document.getElementById("contact_info").innerHTML = "<li>" + gather_form_elements[i] + "</li>";
}
}
Because you are overiding it on every iteration. Try to accumulate the html before using innerHTML like this:
var html = "";
for(var i = 0; i < gather_form_elements.length; i++) {
html += "<li>" + gather_form_elements[i] + "</li>";
// ^^ the += is crucial. If you don't use it, it will just replace the content of html (the innerHTML in your code), we need to use += to append to html instead of overriding it.
}
document.getElementById("contact_info").innerHTML = html;
You can acheive the same result using only one line of code:
document.getElementById("contact_info").innerHTML =
'<li>' + gather_form_elements.join('</li><li>') + '</li>';
What I'm trying to do is pretty simple: Add a 1x20 table of input cells inside a div.
I created a JavaScript function
var tableHTML = function(attributes, rows, columns)
{
var retHTML = "<table " + attributes + ">";
for (var i = 0; i < rows; ++i)
{
retHTML += "<tr>";
for (var j = 0; j < columns; ++j)
retHTML += "<td> </td>";
retHTML += "</tr>";
}
return (retHTML + "</table>retHTML");
}
to give me the HTML for a table with a specified dimensions and attributes. Then, in the body of my HTML, I put
<div class="inner_div" id="input_table">
<!-- div to house the table -->
</div>
<script type="text/javascript">
document.getElementById("input_table").innerHTML += tableHTML("id=\"input_table\" type=\"input\"", 1, 20);
</script>
which I thought would accomplish the task, but hasn't. I think this is because I'm trying to assign a string object to an HTML object. I kinda assumed that an implicit cast would be made. Anyways, I'm wondering if anyone has a "quick fix" to my problem. I would prefer not to redo my entire approach to the problem, but I also wouldn't mind someone informing me of the proper way to do the type of thing I'm trying to do -- using JavaScript to fill in page HTML on load.
Here's my take on this. I'm learning functional programming, so I do a bunch things here that might seem like their a waste of coding, but here's the concept:
Get the dimensions
Create a single row
Copy that row to make the table
After that return the table.
If you want to add id's, class's, etc... work with the DOM element returned by makeTable.
// Makes a single row
var makeRow = function(_columns) {
var row = document.createElement('tr');
var cell = document.createElement('td');
var cols = _columns;
while (cols) {
row.appendChild(cell.cloneNode(true));
cols--;
}
return row;
}
// Makes a table
var makeTable = function(_rows, _columns) {
var table = document.createElement('table');
var row = makeRow(_columns);
var rows = _rows;
while (rows) {
table.appendChild(row.cloneNode(true));
rows--;
}
return table;
}
I tried your code and it works: the table is generated and obviously empty
But be carrefull: if you do this, you will have two elements with the same ID (input_table)
Is there a plugin or way to make certain table columns (not rows) editable and others not editable
with jQuery?
I have seen plugins for clicking on a cell to make it editable, but I mean explicitly making a cell/column editable or not.
I have a way of doing it but it feels like a bit of a hack job.
Here is my function for making a column editable:
function isEditable(rowArray, headersArray)
{
var counter = 0;
var notEditable = ['product code', 'product'];
for(i in rowArray){
counter = 0;
data = headersArray[i].toLowerCase();
for(a in notEditable){
if(data == notEditable[a]){
counter++;
}
}
if(counter > 0){
rowArray[i] += 'notEditable';
}
}
return rowArray;
}
it compares the header of the cell to an array of predefined values which = a non-editable column.
Then I build the row:
function buildHTMLTableRow(row, mutable)
{
output = '';
output += '<tr>';
for(var i = 0; i < row.length; i++)
{
value = trim(row[i]);
if(mutable){
index = value.indexOf('notEditable');
if(index != -1){
value = value.substring(0, index);
output += '<td>' + value + '</td>';
}
else{
output += '<td><input size="5" type="text" value="' + value + '" /></td>';
}
}
else{
output += '<td>' + value + '</td>';
}
}
output += '</tr>';
return output;
}
The mutable parameter decides if the row is editable or not, and the indexOf('noteditable') decides for the cell(but pretty much column) from the isEditable function.
Is there a plugin that does this better, or should I just settle with what I have?
Visit this jsFiddle link: Disable Columns
Following is the data flow:
I have created a row Array named "rowsD". When page loads I am populating my table (id=myData) with these rows.
Now creating another array called disableHeaders wherein I am passing the headers,
which you need to disable entire columns.
I am calling function disableFields passing disableHeaders as parameter
In the function, first I am fetching the index of the header whose value is equal to the values in headers array
If I find one, then from Input tag I am extracting the Value attribute using $(this).find('input') selector
Finally I am replacing the current child with Label tag passing the extracted Input tags Value
You may also comment out disableFields(disableHeaders); line to actually see, how table gets rendered initially
Thank you
