Can you help me plz. In my code i create elements(div) with table elements in it.
When i put "blue_button" - creates a new div with table in it. The table has 5 td rows. I need to numbering only 1st rows. I mean when i put blue_button twice, the first row in first table in first div - has number 1, the second(i need) must have number 2 (for example).
I "broke my brains". Help plz.
Here is my code:
var unitTableTrTd_1 = [];
var unit = document.createElement('div');
var unitTable = document.createElement('table');
unit.appendChild(unitTable);
var unitTableTr = document.createElement('tr');
unitTable.appendChild(unitTableTr);
var unitTableTrTd_1 = document.createElement('td');
var td_1_p = document.createTextNode("1");
unitTableTrTd_1.appendChild(td_1_p);
unitTableTr.appendChild(unitTableTrTd_1);
var unitTableTrTd_2 = document.createElement('td');
unitTableTr.appendChild(unitTableTrTd_2);
var unitTableTrTd_3 = document.createElement('td');
unitTableTr.appendChild(unitTableTrTd_3);
var unitTableTrTd_4 = document.createElement('td');
unitTableTr.appendChild(unitTableTrTd_4);
var unitTableTrTd_5 = document.createElement('td');
unitTableTr.appendChild(unitTableTrTd_5);
unit.id = "block";
wrapper.appendChild(unit);
Its very simple,
take a global variable table_index ( outside button click's callback )
var table_index = 0;
now on each button click's callback increment the table_index by 1, and use it;
table_index++;
var td_1_p = document.createTextNode( table_index );

Hello i try to generate a table with only one column. So my Links get displayed in only one column.
Here is my function:
function createTableForPdfFiles() {
//To Create The Table
var table = document.createElement("table");
table.setAttribute('id', 'pdfTable');
table.setAttribute('class', 'AANTable');
// insert Title Row
var TitleRow = table.insertRow();
var cell = TitleRow.insertCell();
cell.setAttribute('class', 'AANTitleRow');
cell.setAttribute('colSpan', pdfFiles.length + 1);
cell.appendChild(document.createTextNode("Datenblätter"));
//Insert Table Rows
var pdfRow = table.insertRow();
var cell = pdfRow.insertCell(); //Where the PDF´s are displayed
cell.setAttribute('class', 'AANPdfRow');
for (var i = 0; i < pdfFiles.length; i++) {
var cell = pdfRow.insertCell();
var link = document.createElement("a");
link.setAttribute("href", "www.test.at" + pdfFiles[i].Link);
var linktext = document.createTextNode(pdfFiles[i].Link);
link.appendChild(linktext);
cell.appendChild(link);
cell.setAttribute('class', 'AANPdfCell');
}
$("#divTable").append(table);
}
Right now it looks like:
But i want it to look like:
So how i can i make that possibe? I tried to add another Row to the table but the debugger says not supported...... Any help would be really great.
thanks for your Time.
You have to create anew row foer each pdf.
Hae to put this
var pdfRow = table.insertRow();
var cell = pdfRow.insertCell(); //Where the PDF´s are displayed
cell.setAttribute('class', 'AANPdfRow');
Inside the for
take a look at this -> fiddle
http://jsfiddle.net/waH5S/6/
function add_row_retail() {
$(document).ready(function () {
var table = document.getElementById("Retail");
var row = table.insertRow(-1);
var row_id = $('#Retail').val('tr[id]:last');
console.log(row_id);
var cell_init = row.insertCell(-1);
cell_init.innerHTML = "blank";
});
}
I am trying to get the id of the table row(<tr>) before the added row, and then add 1 to this, with proper parseint(...). Then doing the same with the cell (<td>) next, so that every cell has a unique id for each table. I can't seem to find the row's id.
HERE IS THE "CORRECT" CODE FOR MY QUESTION
function add_row_retail() {
var table = document.getElementById("Retail");
// Row id
var row_id = $('#Retail tr:last').attr('id');
var row = table.insertRow(-1);
var next_row_id = "tr_" + (1+parseInt(row_id.match(/\d+/)[0],10));
$(row).attr('id', next_row_id);
for (var i = 0; i < 8; i++) {
var cell_id = $('#Retail td:last').attr('id');
console.log(cell_id);
var next_cell_id = "td_" + (1+parseInt(cell_id.match(/\d+/)[0],10)); console.log(next_cell_id);
var cell = row.insertCell(-1);
$(cell).attr('id', next_cell_id);
$(cell).innerHTML = "blank";
}
}
Rather than $('#Retail').val('tr[id]:last'); I think you want:
var row_id = $('#Retail tr:last').attr('id')
This selector finds the last tr under the #Retail element, and returns its id attribute.
jQuery last selector: http://api.jquery.com/last-selector/
Next problem: IDs cannot start with numbers. Rename your IDs like "tr_1", "tr_2", etc.
Next problem: To extract the numbers from a string:
"tr_123".match(/\d+/)[0]; // returns 123.
Add 1 to it:
var next_id = "tr_" + (1+parseInt("tr_123".match(/\d+/)[0],10));
Then, set your new id.
var row = table.insertRow(-1);
...
$(row).attr('id', next_id);
I have select tag within a cell in the table. I want to add a new row only if the option is selected in the previous rows. I just want to know how to achieve it using DOM.
This is my addRow javascript function
function addRow()
{
var newRow = document.all("estTable").insertRow();
var tblObj = document.getElementById("estTable");
var noOfRow = document.getElementById("estTable").rows.length;
var oCell = newRow.insertCell();
oCell.innerHTML = tblObj.rows[1].cells[0].innerHTML;
oCell.childNodes[0].selectedIndex =0;
oCell = newRow.insertCell();
oCell.innerHTML = tblObj.rows[1].cells[1].innerHTML;
oCell.childNodes[0].selectedIndex =0;
oCell = newRow.insertCell();
oCell.innerHTML = tblObj.rows[1].cells[2].innerHTML;
}
Your new code would use:
var objParent = document.getElementById("someUniqueId");
Where someUniqueId is the row you want to get the parent of. From here you can access the parent anyway you want to.
This code generates a ledger. I narrowed it down to the minimum. By clicking a plus sign it adds an additional row to the ledger.
I'm looking to add each total of the variable newAmount and locate its updated total in a TD to the right of each row. I created newAmount.id = "mainAmount"; to create unique IDs thinking this would help.
var mainNumber = 0;
function addElement()
{
//add a number for each row
mainNumber++;
//create each row, id each slot, and add it where it goes
newDiv = document.createElement("div");
newDiv.id = "main";
newTable = document.createElement("table");
newTable.id = "mainTable";
newDiv.appendChild(newTable);
newTr = document.createElement("tr")
newTr.id = (mainNumber);
newTr.className = "mainRow";
newTable.appendChild(newTr);
newAmount = document.createElement("td");
newAmount.id = "mainAmount";
newAmount.className = (mainNumber);
newPlus = document.createElement("td");
newPlus.id = "mainPlus";
newTotalTable = document.createElement("table");
newDiv.appendChild(newTotalTable);
newTotalTable.id = "mainTotalTable";
newTotalTr = document.createElement("tr");
newTotalTable.appendChild(newTotalTr);
newTotalTr.id = "mainTotalTr";
newTotalTd = document.createElement("td");
newTotalTd.id = "mainTotalTd" + (mainNumber);
newTr.appendChild(newAmount);
newTotalTr.appendChild(newTotalTd);
//whats default inside of each slot
newAmount.innerHTML = '<form name="formAmount"><textarea name="textAmount" size="25" onfocus="wait();" id="amount' + (mainNumber) + '">0</textarea>';
newTr.appendChild(newPlus);
//click this to add a row
newPlus.innerHTML = '<img src="images/plus.png">';
// add the newly created element and it's content into the DOM
my_div = document.getElementById("mainAnchor");
document.body.insertBefore(newDiv, my_div);
}
//doesn't work...trying to hover over any row and show var idName in console
function trHover(){
$('tr').hover(function() {
var idName = $('tr'+'#'+(mainNumber)).attr('id');
console.log(idName);
});
}
//when you focus on amount box, this is activated, which adds attribute onblur and stars addTotal
function wait(){
var blurred = $(this).attr("onblur");
blurred = addTotal();
}
//adds total and displays it in td to the right
function addTotal(){
var y = 1;
var sum = 0;
var input;
while( ( input = document.getElementById( 'amount'+y ) ) ) {
sum += parseInt( input.value );
++y;
console.log(sum);
$("#mainTotalTd1").text(sum);
}
}
Rather than adding a single row, it looks like clicking the plus sign adds a div and two tables, so I'm not sure what you are going for there. I can fix the hover function, though:
$('tr').hover(function() {
var idName = $(this).attr('id'); // 'this' is the element being hovered
console.log(idName);
});
How can I apply an element ID to a newly created element through JavaScript DOM?
The code I have written creates a table which is triggered from a button.
I need to apply a unique ID to this table so it can be styled differently to others which appear on my site.
Here is a sample of my code:
var tab = document.createElement("ViewShoppingCart");
document.getElementById("shopping_list").appendChild(tab);
var tbdy = document.createElement("tbody");
tab.id = "new_cart";
tab.appendChild(tbdy);
new_cart = true;
var total = 0;
for (var a = 0; a <= nameArray.length-1; a++) {
var tr = document.createElement("tr");
tbdy.appendChild(tr);
var td = document.createElement("td");
td.appendChild(document.createTextNode("x " + quantityArray[a]));
tr.appendChild(td);
var td2 = document.createElement("td");
td2.appendChild(document.createTextNode(nameArray[a]));
tr.appendChild(td2);
var td3 = document.createElement("td");
td3.appendChild(document.createTextNode(sumArray[a]));
tr.appendChild(td3);
}
Try
var tbdy = document.createElement("tbody");
tbdy.id = "newtbodyid";
tab.id = "new_cart";
tab.appendChild(tbdy);
new_cart = true;
For applying styles consider using class selectors, you may not need IDs at all.
Note that if you want to create valid HTML you can't have duplicated IDs that significantly lessens value for CSS styles, especially for table data.
