First and most important thing to change is the tag you're using for your add row button. By using a button you're going to cause the form to submit each time you press it, thereby undoing your row add and any other page changes. Use an < input > tag with type button if you want the same look. You'll probably want to do the same with your save edit and delete buttons if you want the page to respond without reloading.
For everything else you're pretty much there. If I were you I would stop using setAttribute for everything. You can set the id and onclick of an element by a direct property set (ie table.id = "myTable";). I typically only use setAttribute for inline style when I want to set more than one property at once (ie table.setAttribute("style","border:2px solid;color:red;");
Here's my version of your code that works.
window.onload = function(){
var addTable = function() {
var checkbox = document.createElement('input');
checkbox.type = "checkbox";
var input = document.createElement('input');
input.type = "text";
input.placeholder = "Firstname";
var input1 = document.createElement('input');
input1.type = "text";
input1.placeholder = "Lastname";
var input2 = document.createElement('input');
input2.type = "email";
input2.placeholder = "Email";
var input3 = document.createElement('input');
input3.type = "number";
input3.placeholder = "Number";
var btnSave = document.createElement('button');
btnSave.innerHTML = "Save";
var btnDelete = document.createElement('button');
btnDelete.innerHTML = "Delete";
var btnEdit = document.createElement('button');
btnEdit.innerHTML = "Edit";
var row = document.createElement('tr');
table.appendChild(row);
addCell(row,checkbox);
addCell(row,input);
addCell(row,input1);
addCell(row,input2);
addCell(row,input3);
addCell(row,btnSave);
addCell(row,btnEdit);
addCell(row,btnDelete);
};
var form = document.createElement('form');
form.method = "post";
document.body.appendChild(form);
var table = document.createElement('table');
table.id = "myTable";
form.appendChild(table);
var btnClick = document.createElement('input');
btnClick.type = "button";
btnClick.value = "Add Row";
btnClick.onclick = addTable;
form.appendChild(btnClick);
};
function addCell(row,elm){
var cell = document.createElement('td');
row.appendChild(cell);
cell.appendChild(elm);
}

I'm trying to create a search datalist with DOMs, and populating the datalist with options from allCardsArray. I know that the option.value is working, but none of the options are being appended to the datalist. Below is the simple table I'm trying to make. I appreciate the help.
function generate_topnav(lowerCaseHeroName, allCardsArray){
var body = document.getElementsByTagName("body")[0];
var tbl = document.createElement("table");
var tblBody = document.createElement("tbody");
var row = document.createElement("tr");
var cell1 = document.createElement("td");
var database = document.createTextNode("OverRealm Card Database")
database.id = 'database';
cell1.appendChild(database);
row.appendChild(cell1);
var cell2 = document.createElement('td');
var input = document.createElement('input');
input.style.fontSize = '18pt';
input.style.height = '56pt';
input.style.width = '300px';
input.setAttribute('placeholder', ' Search for a card...');
input.setAttribute = ('type', 'text');
input.id = 'minionSearch';
input.setAttribute = ('list', 'cardSearch');
input.onchange = function() {
redirect(value);
};
cell2.appendChild(input);
var datalist = document.createElement('datalist');
datalist.id = 'cardSearch';
//THIS IS WHERE I'M TRYING TO POPULATE OPTIONS IN DATALIST
allCardsArray.forEach(function(item){
var option = document.createElement('option');
option.value = item;
datalist.appendChild(option);
});
input.appendChild(datalist);
row.appendChild(cell2);
tblBody.appendChild(row);
tbl.appendChild(tblBody);
body.appendChild(tbl);}
I originally did this in HTML and it worked and it looked like this:
<input style="font-size:18pt; height:56px; width:300px;" type="text" id="minionSearch" list="cardSearch" placeholder=" Search for a card..." onchange="javascript:redirect(value)">
<datalist id="cardSearch"></datalist>
<script>
var list = document.getElementByID("cardSearch");
allCardsArray.forEach(function(item){
var option = document.createElement('option');
option.value = item;
list.appendChild(option);
});
</script>
I'm curious as to why my DOMs version isn't working.
input.setAttribute = ('type', 'text'); should be input.setAttribute('type', 'text'); and input.setAttribute = ('list', 'cardSearch'); should be input.setAttribute('list', 'cardSearch');
The <option> elements are being appended to <datalist> element. The issue is that JavaScript at Question does not set .textContent of created <option> element.
So I have a code with check boxes and I need a suggestion for a function to get data from database if the check box is checked. The table name for the database is Shifliigid and the column name which data I use in the check box is shiffer. So any suggestions would be nice (English isn't my first or even second language, so don't be mad for the short and shady explanation)
var nodeTr = document.createElement("tr");
var td_tekst = document.createElement("td");
td_tekst.innerHTML="Motoorika";
var td = document.createElement("td");
td.style.width = "370px";
var input = document.createElement("textarea");
//input.type = "text";
input.name = "//funktsioonide hindamine/funktsioon[" + count + "]/motoorika";
input.value = rowData.motoorika.replace(/<br\/>/g, "\r\n");
input.className = "txt_left";
input.style.width = "368px";
input.style.fontSize = "9pt";
var nodeMotoorika = input;
addChangeListener(input);
td.appendChild(input);
nodeTr.appendChild(td_tekst);
nodeTr.appendChild(td);
evaluationContainer.appendChild(nodeTr);
//This is the part that makes the checkboxes
var nodeTr = document.createElement("tr");
var td_tekst = document.createElement("td");
var td = document.createElement("td");
var echeckbox = document.createElement("input");
echeckbox.type="checkbox";

There is no JS "function to get data from database".
You will have to choose a backend technology to access the database. For example PHP.
Use ajax calls to get the data from database using PHP or asp.
You can check if a particular checkbox is checked using the checked property of DOM.
I am creating a dynamic form to submit with few input elements, but it does not send a request. I use fiddler to check
Here is my code
var form_ref = document.createElement("form");
form_ref.id = "viewform";
form_ref.name = "viewform";
form_ref.action = "/csm/showResult.action";
form_ref.method = "post";
form_ref.target = "_self";
var cfgidField = document.createElement("input");
cfgidField.name = "cfgid";
cfgidField.type = "text";
cfgidField.value = configid;
form_ref.appendChild(cfgidField);
var cfgnameField = document.createElement("input");
cfgnameField.name = "cfgname";
cfgnameField.type = "text";
cfgnameField.value = configname;
form_ref.appendChild(cfgnameField);
var cfgdescField = document.createElement("input");
cfgdescField.name = "cfgdesc";
cfgdescField.type = "text";
cfgdescField.value = configdesc;
form_ref.appendChild(cfgdescField);
var cfgenvField = document.createElement("input");
cfgenvField.name = "cfgenv";
cfgenvField.type = "text";
cfgenvField.value = configenv;
form_ref.appendChild(cfgenvField);
var cfgfileField = document.createElement("input");
cfgenvField.name = "cfgfile";
cfgenvField.type = "text";
cfgenvField.value = absolutepath;
form_ref.appendChild(cfgfileField);
var cfgdateField = document.createElement("input");
cfgenvField.name = "updatedDate";
cfgenvField.type = "text";
cfgenvField.value = absolutepath;
form_ref.appendChild(cfgdateField);
form_ref.submit();
Maybe you have the same problem seen here:
Why can't I submit a dynamically created form in Firefox
it basically says to append it to your document.body before submitting.
With javascript, i want my checkbox to change the text decoration of an input text field.
So when it's checked, the text in the input text field turns bold.
Remember i'm learning so i'm not a pro as you guys ;)
I thought something like this;
var checkbox = create("input");
checkbox.type = "checkbox";
checkbox.id = "checkboxId" + counter;
div.appendChild(checkbox);
checkbox.onClick="boldChange(this)"
var input = create("input");
input.type = "input";
input.id = "inputId" + counter;
div.appendChild(input);
function boldChange()
var boldgroup = document.getElementsByName(el.name);
for (var b=0; boldgroup[b]; ++b)
inputId.style.textDecoration = boldgroup[b].checked ? 'bold' : 'none';
}
How can i make this work?
Thank you so much in advance
Here is a working JSFiddle example based on your code above: Link to example
Code snippet: (place below </body> so that all of DOM is loaded)
<script>
var div = document.getElementById('div'),
counter = 0;
var checkbox = document.createElement("input");
checkbox.type = "checkbox";
checkbox.id = "checkboxId" + counter;
div.appendChild(checkbox);
checkbox.onclick = boldChange;
counter++;
var input = document.createElement("input");
input.type = "text";
input.id = "inputId" + counter;
div.appendChild(input);
function boldChange() {
input.style.fontWeight = (checkbox.checked)?'bold':'normal';
}
</script>
I am trying to create a checkbox dynamically using following HTML/JavaScript. Any ideas why it doesn't work?
<div id="cb"></div>
<script type="text/javascript">
var cbh = document.getElementById('cb');
var val = '1';
var cap = 'Jan';
var cb = document.createElement('input');
cb.type = 'checkbox';
cbh.appendChild(cb);
cb.name = val;
cb.value = cap;
cb.appendChild(document.createTextNode(cap));
</script>
You're trying to put a text node inside an input element.
Input elements are empty and can't have children.
...
var checkbox = document.createElement('input');
checkbox.type = "checkbox";
checkbox.name = "name";
checkbox.value = "value";
checkbox.id = "id";
var label = document.createElement('label')
label.htmlFor = "id";
label.appendChild(document.createTextNode('text for label after checkbox'));
container.appendChild(checkbox);
container.appendChild(label);
The last line should read
cbh.appendChild(document.createTextNode(cap));
Appending the text (label?) to the same container as the checkbox, not the checkbox itself
You can create a function:
function changeInputType(oldObj, oTyp, nValue) {
var newObject = document.createElement('input');
newObject.type = oTyp;
if(oldObj.size) newObject.size = oldObj.size;
if(oldObj.value) newObject.value = nValue;
if(oldObj.name) newObject.name = oldObj.name;
if(oldObj.id) newObject.id = oldObj.id;
if(oldObj.className) newObject.className = oldObj.className;
oldObj.parentNode.replaceChild(newObject,oldObj);
return newObject;
}
And you do a call like:
changeInputType(document.getElementById('DATE_RANGE_VALUE'), 'checkbox', 7);
/* worked for me */
<div id="divid"> </div>
<script type="text/javascript">
var hold = document.getElementById("divid");
var checkbox = document.createElement('input');
checkbox.type = "checkbox";
checkbox.name = "chkbox1";
checkbox.id = "cbid";
var label = document.createElement('label');
var tn = document.createTextNode("Not A RoBot");
label.htmlFor="cbid";
label.appendChild(tn);
hold.appendChild(label);
hold.appendChild(checkbox);
</script>
