The program is a Seat reservation program rows 1 and 2 are first class, row 3-9 are business class and rows 10 through 13 are economy. They are initialized to * and become X when it is reserved. and alert you if the seat is already filled.
The rows will fill for the first 6 rows but it ignores request for row 7 and beyond. But i know it goes to the appropriate function because if i request Economy with row 3 (which is invalid) it alerts me. But if i ask for first class with row7 it will act like nothing has been requested.
It won't let me post the html code but it will display as row1-13 on the left and A - F across the top. I use drop down list and I set the values to the corresponding for the options to their corresponding spot in a the 2-d array (eg if i select row 5 and seat c the value of row 5 is 5 and the value of C is 3)
var rowSeat;

j++;

rowSeat[i][0] = "Row "+i;

}
}
window.addEventListener("load",start, false);
</script>
var row = inputField.options[inputField2.selectedIndex].value;
inputField.options should be inputField2.options
inputField.options only goes to 6 because you only have 6 seats wide, but you are trying to look at the row in the seat list.

The thing that I am now looking for and is unable to do is how do I add a checkbox in the first column in each row. Also upon checking this checkbox the entire row should get highlighted so that I can perform specific task on all the selected items.
As far as I have understood your code, your first column's data is being set as:
tdsentBy.innerHTML = sentBy;
So in the same line, you can add textbox as a string as:
var cbox = "<div class='select-box'>
<input type='checkbox' name='selectBox' class='select-row'>
</div?>"
tdsentBy.innerHTML = cbox + sentBy;
In this way, a checkbox will always be available in first column of every row.
Now in RowSelection function, to bind event you can do something like:
var checkBox = table.rows[i].cells[j].querySelector(".select-row");
checkBox.addEventListener("click",function(evt){
});
I am very new to Javascript, and have a question about one of my functions(checkOrBet). I am trying to make a Texas Hold'em poker game, and the part that doesn't seem to be working is where I test for a regular pair.

//will be computer's response when prompted during the flop
this.checkOrBet = function checkOrBet() {
var response;
//Ace High
if (this.firstCard.rank == "A") {
response = "call";
console.log("Ace High!");
} else if (this.secondCard.rank == "A") {
response = "call";

I am trying to swap two array in javascript. While the replacement comes to the last iteration, I am getting "NotFoundError: Node was not found" in the call of parent.replaceChild(item2,item1). Please help me what mistake I have committed.
function sortTable(col){
if($("loacte-resultsTable") == null || $("loacte-resultsTable") == undefined){

// sorting on same column twice = reverse sort order

copyArr = new Array(); //holds an original copy of the sort data to match to colArr
resultArr = new Array(); //holds the output
allNums = true

The call to the sortTable method is from synch().This is the UI part coded in JS:
function synch(){
var loacteResults = $('loacte-results');
var loacteResultsTable = $('loacte-resultsTable');
tab = loacteResults.getElementsByTagName('TABLE')[0];
loacteResults.removeChild(tab);
var updatedResults =
'<table id="loacte-resultsTable" cellspacing="0" cellpadding="3" border="1">' +
'<thead class="thead">' +
'<tr>' +
'<th>Site ID</th>' +
'<th>Store Name</th>' +
'<th>Agent Code</th>' +
'<th>Address</th>' +
'<th>City, State</th>' +
'<th>Phone</th>' +
'<th>Hours</th>' +
'<th>Deleted</th>' +
'<th width="65px;">Priority <img src="images/sort_up_down.gif" onclick="javascript:sortTable(8)" style="cursor: pointer;"/></th>' +
'<th width="115px;">Est.Dist.(miles) <img src="images/sort_up_down.gif" onclick="javascript:sortTable(9)" style="cursor: pointer;"/></th>' +
'</tr>' +
'</thead>' ;
if(tr == '')
updatedResults = updatedResults + '<tbody><tr><td colspan="10">No Stores to display</td></tr></tbody></table>';
else
updatedResults = updatedResults + '<tbody>' + tr + '</tbody></table>';
loacteResults.innerHTML = updatedResults;
}
In the third parent.replaceChild line item1 is no longer is on the page, since it has been replaced with item2.
Your code broken down:
function swapNodes(item1,item2)
{
var itemtmp = item1.cloneNode(1); //create a copy of item 1
var parent = item1.parentNode; //set a reference to the parent
item2 = parent.replaceChild(itemtmp,item2); //replace item2 with the copy of item1 and store the old child in item2
parent.replaceChild(item2,item1); //replace item1 with item2
parent.replaceChild(item1,itemtmp); //this line is redundant. <-- item1 no longer is on the page.
itemtmp = null;
}
I am trying to create mine field game. "I am very new to Js".
What I have done so far:
var level = prompt("Choose Level: easy, medium, hard");
if (level === "easy") {
level = 3;
} else if (level === "medium") {
level = 6;
} else if (level === "hard") {
level = 9;
}
var body = document.getElementsByTagName("body")[0];
var tbl = document.createElement("table");
var tblBody = document.createElement("tbody");
for (var i = 1; i <= 10; i++) {
var row = document.createElement("tr");
document.write("<br/>");
for (var x = 1; x <= 10; x++) {
var j = Math.floor(Math.random() * 12 + 1);
if (j < level) {
j = "mined";
} else {
j = "clear";
}
var cell = document.createElement("td");
var cellText = document.createTextNode(j + " ");
cell.appendChild(cellText);
row.appendChild(cell);
}
tblBody.appendChild(row);
}
tbl.appendChild(tblBody);
body.appendChild(tbl);
tbl.setAttribute("border", "2");
So I create here 2d table and enter 2 random values in rows and columns (mined or clear).
Where I am stuck is:
Check if td = mined it dies otherwise open the box(td) etc.
How do I assign value of td? I mean how can I check which value(mined/clear) there is in the td which is clicked?
Ps: Please don't write the whole code:) just show me the track please:)
Thnx for the answers!
Ok! I came this far.. But if I click on row it gives sometimes clear even if I click on mined row or vice versa!
// create the table
var body = document.getElementsByTagName("body")[0];
var tbl = document.createElement("table");
tbl.setAttribute('id','myTable');
var tblBody = document.createElement("tbody");
//Create 2d table with mined/clear
for(var i=1;i<=10;i++)
{
var row = document.createElement("tr");
document.write("<br/>" );
for(var x=1;x<=10;x++)
{
var j=Math.floor(Math.random()*12+1);
if(j<level)
{
j = "mined";
}
else{
j = "clear";
}
var cell = document.createElement("td");
var cellText = document.createTextNode(j + "");
cell.appendChild(cellText);
row.appendChild(cell);
}
tblBody.appendChild(row);
}
tbl.appendChild(tblBody);
body.appendChild(tbl);
tbl.setAttribute("border", "2");
//Check which row is clicked
window.onload = addRowHandlers;
function addRowHandlers() {
var table = document.getElementById("myTable");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
var currentRow = table.rows[i];
var createClickHandler =
function(row)
{
return function() {
var cell = row.getElementsByTagName("td")[0];
var id = cell.innerHTML;
if(id === "mined")
{
alert("You died");
}else
{
alert("clear");
}
};
}
currentRow.onclick = createClickHandler(currentRow);
}
}
I think I do something wrong with giving the table id "myTable"..
Can you see it?
Thank you in advance!
So, the idea would be:
assign a click event to each td cell:
td.addEventListener('click', mycallback, false);
in the event handler (callback), check the content of the td:
function mycallback(e) { /*e.target is the td; check td.innerText;*/ }

JavaScript, getting value of a td with id name
I have this code that sends the values a user have typed in... the information and numbers are sent as an array and pushed into another array, I then display the text in a dynamically created list element and number in a span element...
var button = $('#add');
button.click(function()
{
var filmnamn = $('#name');
var filmnamnet = filmnamn.val();
var betyg = $('#star');
var betyget = betyg.val();
betyget = Number(betyget);
if(filmnamnet == 0)
{
$('#name').css('background-color', 'red');
}
if(betyget == 0)
{
$('#star').css('background-color', 'red');
}
if(betyget == 0 || filmnamnet == 0)
{
alert("Vänligen fyll i fälten korrekt");
}
else
{
var array = new Array();
array.unshift(betyget);
array.unshift(filmnamnet);
film_array.unshift(array);
betyg_array.unshift(array);
updateFilmList();
}
});
var film_list = $("#filmlista");
var film_array = new Array();
function updateFilmList()
{
document.getElementById("name").value = '';
document.getElementById("star").value = 0;
var filmen = film_array[0][0];
var grade = film_array[0][1];
var element = '<li class="lista">' + filmen + '<span class="betyg">'+ grade +'</span></li>';
film_list.append(element);
changeNumber();
}
And at last I have the function that i want to change the number in the span element to the amount of stars that the number shows... this works fine but only for the first created list and span element, when I try to add more listelements the number wont show up as stars, can someone tell me why this happens and point me in the direction to fix the problem?
function changeNumber(){
var elements= document.getElementsByClassName("betyg");
for (var i=0; i<elements.length; i++) {
var element = elements[i];
var length = parseInt(element.innerHTML);
var x=Array(length+1).join("*");
element.innerHTML=x;
}
}
