I am trying to add several buttons to a table using javascript, however I keep being offered this result with [objectHTMLInputElement]
Here is my code:
function createDiseaseTable(country){
var displayCountry = document.getElementById("countrySelected");
displayCountry.innerHTML = country.name;
var diseaseTable = document.getElementById("diseases");
diseaseTable.innerHTML = "";
for (var i = 0; i<country.diseases.length; i++) ////////////////////////////////////
{
var changeDisease = document.createElement('input');
changeDisease.type = 'button';
changeDisease.name = "x"
changeDisease.onclick = hi();
var row = diseaseTable.insertRow(i);
var cell1 = row.insertCell(0)
var cell2 = row.insertCell(1)
var cell3 = row.insertCell(2)
var cell4 = row.insertCell(3)
var cell5 = row.insertCell(4);
cell1.innerHTML = OurDiseases[i].name;
cell2.innerHTML = OurDiseases[i].cureLevel;
cell3.innerHTML = OurDiseases[i].killLevel;
cell4.innerHTML = OurDiseases[i].cured;
cell5.innerHTML = changeDisease;
console.log(changeDisease);
}
var row = diseaseTable.insertRow();
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
cell1.innerHTML = "Disease";
cell2.innerHTML = "Level needed to cure";
cell3.innerHTML = "Deaths each year";
cell4.innerHTML = "Cured";
cell5.innerHTML = "More Info";
}
Note: I'm not concerned about not running a function yet upon click, i just want the actual button to appear
you need to use the appendChild function
your code could than look like this:
...
cell5.appendChild(changeDisease);
...
You can find more details on this function here: http://www.w3schools.com/jsref/met_node_appendchild.asp
Update - see comment:
name is an attribute of an element and not the caption of the button, if you want to set the caption use the attribute value instead - here is an example: http://www.w3schools.com/html/tryit.asp?filename=tryhtml_button
It's been a long time since I've done DOM manipulation without jQuery, but I believe you need to do cell5.appendChild(changeDiseas) rather than .innerHTML (which is expecting an HTML string).

I'm trying to add a onclick event to a newly dynamically created button inside a row cell in a table.
When I try to use the button this appears in the console:
"Uncaught ReferenceError: i is not defined"
How can I access the variable i to put it inside the parenthesis of the change() function?
cell9.innerHTML ='<input type = "button" value = "Edit" onclick="change(i)"/>';
Edit: So here is the entire function, i is a number that increases by 1 every time this function is used. The variable count is equal to the length of the table.
function save(){
var myTable = document.getElementById("myTable");
var i = count;
// Create an empty <tr> element and add it to the 1st position of the table:
var row = myTable.insertRow(myTable.rows.length);
row.id="row-"+i;
// Insert new cells (<td> elements)in the"new" <tr> element:
var cell0 = row.insertCell(0);
var cell1 = row.insertCell(1);
var cell2 = row.insertCell(2);
var cell3 = row.insertCell(3);
var cell4 = row.insertCell(4);
var cell5 = row.insertCell(5);
var cell6 = row.insertCell(6);
var cell7 = row.insertCell(7);
var cell8 = row.insertCell(8);
var cell9 = row.insertCell(9);
var cell10 = row.insertCell(10);
// Add some text to the new cells:
cell0.innerHTML = document.getElementById("fname2").value;
cell1.innerHTML = document.getElementById("lname2").value;
cell2.innerHTML = document.getElementById("cemail2").value;
cell3.innerHTML = document.getElementById("pnumber2").value;
cell4.innerHTML = document.getElementById("city2").value;
cell5.innerHTML = document.getElementById("address2").value;
cell6.innerHTML = document.getElementById("postalCode2").value;
cell7.innerHTML = document.getElementById("province2").value;
cell8.innerHTML = document.getElementById("cpwd2").value;
cell9.innerHTML ='<input type = "button" value = "Edit" onclick="change(i)"/>';
}
You have to inject the i into element by string concatenation or Template literals like below
cell9.innerHTML ='<input type = "button" value = "Edit" onclick="change('+ i + ')"/>';
or
cell9.innerHTML =`<input type = "button" value = "Edit" onclick="change(${i})"/>`;
Is it possible to get information, such as the id, value, of a button created by a javascript loop? For example, the following code, which creates a button for each line in a table formed by an array of objects?
var table = document.createElement("TABLE");
table.setAttribute("id", "tableOfArray");
var array = [ (a large array of objects here) ];
for (var i = 0; i < array.length; i++)
{
row = table.insertRow(i);
cell1 = row.insertCell(0);
cell2 = row.insertCell(1);
cell3 = row.insertCell(2);
cell4 = row.insertCell(3);
cell5 = row.insertCell(4);
cell6 = row.insertCell(5);
cell1.innerHTML = i + 1; //for numbering the table
cell2.innerHTML = array[i].property1;
cell3.innerHTML = array[i].property2;
cell4.innerHTML = array[i].property3;
cell5.innerHTML = array[i].property4;
var button = document.createElement("BUTTON");
var buttonText = document.createTextNode("Remove Line");
button.appendChild(buttonText);
button.setAttribute("id", String(i));
button.setAttribute("value", String(i));
button.setAttribute("onClick", "remove()");
cell6.appendChild(button);
}
function remove()
{
?? //gets the value of the button that was pressed
var buttonValue = ??; //assigns the value of button to the variable
arrayTable = document.getElementById("tableOfArray");
table.deleteRow(buttonValue);
}
Is there a method that can be used to get the id or value of the button in order to perform the remove action?
you can pass the current context by passing this
button.setAttribute("onClick", "remove(this.id)");
function remove(id){
var _id=id;// id of the button;
}
Else you can use the event object
function remove(event){
var _target = event.target;
var _getId = _target.id;
var _getParentTD = _target.parentElement; // will give the td which contain button
var _getParentTR = _target.parentElement.parentElement; // will return tr
}
I am creating a page which is dynamically fetching entries from a JSON file and is displaying it in the form of table I have written the code to create the table in Java script, but it is fetching all the entries at once. I'm trying to create a pagination with only 10 entries per page and trying to create a sort. Here's the function for creating the table.
function myFunction32()
{
var table = document.getElementById("contentTable");
table.innerHTML = "";
var row = table.insertRow(0);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
cell1.innerHTML = "Disk ID";
cell2.innerHTML = "Serial Number";
cell3.innerHTML = "Hypervisor IP";
cell4.innerHTML = "TIER";
cell5.innerHTML = "Total Capacity";
for(var i=0; disk.length;i++)
{
var row = table.insertRow(i+1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
cell1.innerHTML = disk[i].disk_id;
cell2.innerHTML = disk[i].disk_serial_id;
cell3.innerHTML = disk[i].hypervisor_ip;
cell4.innerHTML = disk[i].storage_tier;
cell5.innerHTML = disk[i].disk_size +" GiB";
}
I have updated the code to include 10 entries per page, but I am not able to create a new button for next page along with sorting.
I am calling my table in the HTML as follows
<div id="fatal" style="margin-left:20px;margin-right:10px;">
<table id = "contentTable" class="table table-bordered"></table>
</div>
Thanks for any help.
I had this same problem and I solved using jQuery datatable, take a look on my gist https://gist.github.com/dptole/08f090b3cbe00e8ba937. You gonna have to edit and apply to your scenario.
From line 65 to 67 I have a wrapper to return the API endpoint string, without actually requesting it.
I want to add row and change the style of it. I use javascript to add cell and row, but I can't change style the of cell and can't change the property of new row.
Any one please suggest to change it. Let my script is
var table = document.getElementById("dataTable");
var row = table.insertRow(5);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(3);
var cell4 = row.insertCell(4);
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
cell3.innerHTML = "NEW CELL3";
cell4.innerHTML = "NEW CELL4";
You can set the height and color like this :
document.getElementById('dataTable').style.backgroundColor="#FFFFFF";
document.getElementById('dataTable').style.height="50";
document.getElementById('dataTable').style.textAlign="center";
Use element.style.property='value' to set the style of the element.
If there are multiple css properties to be assigned then use classes(.className) over .style.propertyName
Try this:
var table = document.getElementById("dataTable");
var row = table.insertRow(0);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
cell3.innerHTML = "NEW CELL3";
cell4.innerHTML = "NEW CELL4";
cell1.className = 'yourClass';
cell2.className = 'yourClass';
cell3.className = 'yourClass';
cell4.className = 'yourClass';
.yourClass {
height: 50px;
text-align: center;
background-color: #FFFFFF
}
<table id='dataTable'>
<table>
I have three working bits of javascript that I'm trying to combine... unsuccessfully. I'm trying to make it so when you click a button, it knows that two fields have the same entry. If not, it will make another row in a table in my HTML with the information.
document.getElementById("goRow").addEventListener("click", check)
function check () {
if (document.getElementById("firstName").value == document.getElementById("lastName").value){
prompt('First name can not be last');
}
else {
function newRow() {
var table = document.getElementById("myTable");
var row = table.insertRow(1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
cell1.innerHTML = document.getElementById("firstName").value;
cell2.innerHTML = document.getElementById("lastName").value;
cell3.innerHTML = document.getElementById("email").value;
cell4.innerHTML = " ";
}
}
Like I said, all the different parts work on their own, but I can't get them all to play nice with each other.
Why are you trying to define a function as part of an ELSE condition? You should have that on its own, and call it from the ELSE:
function check() {
if (document.getElementById("firstName").value == document.getElementById("lastName").value) {
prompt('First name can not be last');
} else {
newRow();
}
}
function newRow() {
var table = document.getElementById("myTable");
var row = table.insertRow(1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
cell1.innerHTML = document.getElementById("firstName").value;
cell2.innerHTML = document.getElementById("lastName").value;
cell3.innerHTML = document.getElementById("email").value;
cell4.innerHTML = " ";
}
window.onload() {
document.getElementById("goRow").addEventListener("click", check)
}
function check () {
if (document.getElementById("firstName").value == document.getElementById("lastName").value){
prompt('First name can not be last');
} else {
newRow();
}
}
function newRow() {
var table = document.getElementById("myTable");
var row = table.insertRow(1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
cell1.innerHTML = document.getElementById("firstName").value;
cell2.innerHTML = document.getElementById("lastName").value;
cell3.innerHTML = document.getElementById("email").value;
cell4.innerHTML = " ";
}
