jQuery Clear Data With Each Form Submission - javascript

I have a form where I'd like to allow users to change their inputs. The code below handles the form. I thought that $("tabledata").empty(); would clear it with each submission, but it is not. Instead, the new table is just being appended to the existing.
jQuery(function () {
$('#401k').submit(function (e) {
$("#tabledata").empty();
var salary = [];
var data = $('#401k :input').serializeArray();
currentage = +data[2].value;
retirementage = +data[3].value;
contribution = +data[0].value/100;
salaryincrease = +data[1].value;
tabledata += "<h3>Starting Salary: " + startingsalaryedit + "</h3><h3>401k Match Percentage: " + match + "%</h3>";
tabledata += "<table class=bluetable>";
tabledata += "<tr><th>Age</th><th>Employee Contribution</th><th>Employer Contribution</th><th>Ending Balance (No Contribution)</th><th>Ending Balance (Contributions)</th><th>Ending Balance (Total)</th></tr>";
for (i = currentage; i <= retirementage; i++) {
yearsage = i - currentage;
salary[i] = startingsalary * Math.pow(1+(salaryincrease/100),yearsage);
employeecontribution = (salary[i] * contribution).formatMoney(2,'.',',');
employercontribution = (salary[i] * (match/100)).formatMoney(2,'.',',');
tabledata += "<tr>";
tabledata += "<td>" + i + "</td>";
tabledata += "<td>" + employeecontribution + "</td>";
tabledata += "<td>" + employercontribution + "</td>";
tabledata += "</tr>";
};
tabledata += "</table>";
$("#tabledata").append(tabledata);
e.preventDefault();
});

Problem is you are not declaring
var tabledata = ''
Therefore it is global scoped, and you are just appending to the previous. You can console.log tabledata variable to see.

Pulling data from SQLite, but data is undefined

I have a class project where I need to pull data from my SQLite DB and place it into <table>.
But every time I reload the page I get this Table image and I was hoping for some help. I'm new to JavaScript and I need to finish this task in a few hours, I've tried to pull the data into an object and from the object into this line str += "<td>" + results.rows.item(i).Firstname + "</td>" and still it didn't work.
db.transaction(function (tx) {
tx.executeSql('SELECT * FROM Customers_Table ', [], function (tx, results) {
var len = results.rows.length, i;
document.getElementById("tablea").innerHTML = '';
var str = '';
str += "<th>FirstName</th>";
str += "<th>LastName</th>";
str += "<th>Address</th>";
str += "<th>City</th>";
str += "<th>Email</th>";
for (i = 0; i < len; i++) {
str += "<tr>";
str += "<td>" + results.rows.item(i).Firstname + "</td>";
str += "<td>" + results.rows.item(i).Lastname + "</td>";
str += "<td>" + results.rows.item(i).Address + "</td>";
str += "<td>" + results.rows.item(i).City + "</td>";
str += "<td>" + results.rows.item(i).Email + "</td>";
str += "</tr>";
document.getElementById("tablea").innerHTML += str;
str = '';
}
});
});
Well, considering that you have data in results. It should be used as:
results.rows.item[i].Firstname
NOT
results.rows.item(i).Firstname
Finally figured out the problem, the .Firstname and the rest didn't match the column names from the Db table, it was lowercase,look carefully at your code guys!!

display multiple image into HTML table using jquery [duplicate]

This question already has answers here:
How to return an image from http source in Javascript
(5 answers)
Closed 3 years ago.
Hi I want to display multiple image into html table using jquery check my code for more clearification.
In Console i get only image source as
<img src="uploads/">
$.ajax({
url : 'check.php',
success: function (data) {
data = $.parseJSON(data);
var html = "";
for(var a = 0; a < data.length; a++) {
var firstName = data[a].first_name;
var email = data[a].email;
var dob = data[a].dob;
var country = data[a].country;
var gender = data[a].gender;
var meal= data[a].meal;
var img = data[a].profile_pic;
var array = img.split(',');
for (var i = 0; i < array.length; i++) {
var src = "uploads/"+ array[i];
var img1 = '<img src='+ src +'>';
}
html += "<tr>";
html += "<td>" + firstName + "</td>";
html += "<td>" + email + "</td>";
html += "<td>" + dob + "</td>";
html += "<td>" + country + "</td>";
html += "<td>" + gender + "</td>";
html += "<td>" + meal + "</td>";
html += "<td>" + img1 + "</td>";
html += "</tr>";
document.getElementById("data").innerHTML += html;
}
},
Just move your img content inside for loop.
$.ajax({
url : 'check.php',
success: function (data) {
data = $.parseJSON(data);
var html = "";
for(var a = 0; a < data.length; a++) {
var firstName = data[a].first_name;
var email = data[a].email;
var dob = data[a].dob;
var country = data[a].country;
var gender = data[a].gender;
var meal= data[a].meal;
var img = data[a].profile_pic;
var array = img.split(',');
html += "<tr>";
html += "<td>" + firstName + "</td>";
html += "<td>" + email + "</td>";
html += "<td>" + dob + "</td>";
html += "<td>" + country + "</td>";
html += "<td>" + gender + "</td>";
html += "<td>" + meal + "</td>";
html += "<td>";
for (var i = 0; i < array.length; i++) {
var src = "uploads/"+ array[i];
var img1 = '<img src='+ src +'>';
html += img1
}
html += "</td>";
html += "</tr>";
document.getElementById("data").innerHTML += html;
}
},

Dynamic option list from an array

I have the following code which works perfectly, but can I make the drop menu dynamic using quantityAllowed as the maximum the drop menu goes to. at the moment I have added 10 options for every print, but what i would prefer is the drop menus only have the correct quantity in. I think the loop I need would go where the options begin using the value of the loop, but when i have tried, i just get an error, so I know I have done something wrong.
function arrayData() {
var index;
var text = "<ul>";
var htmlTable = '';
var calcTable = [];
calcTable = [
{ printName:"Name1", printPrice:8000000, quantityAllowed:6},
{ printName:"Name2", printPrice:12000000, quantityAllowed:5},
{ printName:"Name3", printPrice:20000000, quantityAllowed:4},
{ printName:"Name4", printPrice:2000000, quantityAllowed:3},
];//end of array
for (index = 0; index < calcTable.length; index++) {
var myclass = 'class="printwant"';
$("#tbNames tr:last").after("<tr>" +
"<td style='padding:0px 0px 0px 36px;'>" + calcTable[index].printName + "</td>" +
"<td class='printpoints'>" + calcTable[index].printPrice + "</td>" +
"<td>" + calcTable[index].quantityAllowed + "</td>" +
"<td><select " + myclass + "><option value=0>0</option><option value=1>1</option><option value=2>2</option><option value=3>3</option><option value=4>4</option><option value=5>5</option><option value=6>6</option><option value=7>7</option><option value=8>8</option><option value=9>9</option><option value=10>10</option></select></td><td></td> </tr>");
}//end of loop
$("#tbNames tr:last").after("<tr>" + "<td colspan = '5' height=40 > </tr>");
}
You can separate out your HTML generation code from the jQuery DOM assignment. This makes it a little easier to read and manipulate. When you come to your select/option area, drop it into a for... loop to generate the appropriate number of options.
function arrayData() {
var index;
var text = "<ul>";
var htmlTable = '';
var calcTable = [];
calcTable = [
{ printName:"Name1", printPrice:8000000, quantityAllowed:6},
{ printName:"Name2", printPrice:12000000, quantityAllowed:5},
{ printName:"Name3", printPrice:20000000, quantityAllowed:4},
{ printName:"Name4", printPrice:2000000, quantityAllowed:3},
];//end of array
for (index = 0; index < calcTable.length; index++) {
var myclass = 'class="printwant"';
var output = '';
output += "<tr>";
output += "<td style='padding:0px 0px 0px 36px;'>" + calcTable[index].printName + "</td>";
output += "<td class='printpoints'>" + calcTable[index].printPrice + "</td>";
output += "<td>" + calcTable[index].quantityAllowed + "</td>";
output += "<td><select " + myclass + ">";
for( var i=0, x=calcTable[index].quantityAllowed; i<x; i++ ){
output += '<option value="' + i + '">' + i + '</option>';
}
output += "</select></td><td></td> </tr>";
$("#tbNames tr:last").after(output);
}//end of loop
$("#tbNames tr:last").after("<tr>" + "<td colspan = '5' height=40 > </tr>");
}
arrayData();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tbNames">
<tr></tr>
<tr></tr>

Create a table in javascript from returned JSON object by http get

This is the function in my javascript. Triggered by an onclick function by an another function.
function getValueUsingParentTag(){
var tv_type = [];
var screen_size = [];
var connectivity = [];
var features = [];
var chkArray = [tv_type,screen_size,connectivity,features];
$("#tvtype input:checked").each(function() {
tv_type.push($(this).val());
});
$("#screensize input:checked").each(function() {
screen_size.push($(this).val());
});
$("#connection input:checked").each(function() {
connectivity.push($(this).val());
});
$("#feature input:checked").each(function() {
features.push($(this).val());
});
console.log(chkArray);
//alert(JSON.stringify(chkArray));
alert('hello');
$.get("output-tv.php",{tv_type:tv_type,screen_size:screen_size,connectivity:connectivity,features:features},function(chkArray){
});
}
This is the sample json object returned
{"result":[
{"product_code":"B2810","tv_name":"32B2810","size":"32","tv_type":"INTERNET TV"},
{"product_code":"B2610","tv_name":"48B2610","size":"48","tv_type":"INTERNET TV"}
]}
I need to create a table in javascript based on the json object returned. I dont know how. Please Help.
following function builds the table in a string.
function getTable(data) {
var html = "";
html += "<table><tr><td>product_code</td><td>tv_name</td><td>size</td><td>tv_type</td></tr>";
html += "<tr>";
for(var i = 0, ceiling = data.result.length; i < ceiling; i++) {
var row = data.result[i];
html += "<td>" + row.product_code + "</td>";
html += "<td>" + row.tv_name + "</td>";
html += "<td>" + row.size + "</td>";
html += "<td>" + row.tv_type + "</td>";
}
html += "</tr>";
html += "</table>";
return html;
}
suppose you have a div with id mydiv, you can add the table to this div with following code:
document.getElementById("mydiv").innerHTML = getTable(data);
Here's a simple Javascript only loop example:
http://jsfiddle.net/mCLVL/
var tableData = {"result":[
{"product_code":"B2810","tv_name":"32B2810","size":"32","tv_type":"INTERNET TV"},
{"product_code":"B2610","tv_name":"48B2610","size":"48","tv_type":"INTERNET TV"}
]};
var tableHTML = "<table>";
for (var i = 0; i < tableData["result"].length; i++) {
tableHTML += "<tr>";
tableHTML += "<td>" + tableData["result"][i]["product_code"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["tv_name"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["size"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["tv_type"] + "</td>";
tableHTML += "</tr>";
}
tableHTML += "</table>";
console.log(tableHTML);
It will be so simple by using JSRender. I made a fiddle using jsrender template check it.

Creating a table in Javascript

I am reading data from an XML file then displaying it in a table in Javascript. However, only the first row displays well and the rest of the rows dont as follows:
results = "<table class= \"table table-condensed table-hover table-bordered table-striped\">";
results += "<caption>Payment History</caption>";
results += "<thead>";
results += "<tr>";
results += "<th>User</th>";
results += "<th>Video Name</th>";
results += "<th>Payment Date</th>";
results += "<th>Time</th>";
results += "</tr>";
results += "</thead>";
results += "<tbody>";
for (var index = 0; index < items.length; index++)
{
var deviceNumElement = items[index].getElementsByTagName("devicenumber")[0];
var VideoNumElement = items[index].getElementsByTagName("videonumber")[0];
var dateElement = items[index].getElementsByTagName("paymentdate")[0];
var timeElement = items[index].getElementsByTagName("paymenttime")[0];
if (deviceNumElement && VideoNumElement && dateElement && timeElement)
{
deviceNum[index] = deviceNumElement.firstChild.data;
videoNum[index] = VideoNumElement.firstChild.data;
paidDate[index] = dateElement.firstChild.data;
paidTime[index] = timeElement.firstChild.data;
results += "<tr>";
results += "<td>"+ deviceNum[index] + "</td>";
results += "<td>" + videoNum[index] + "</td>";
results += "<td>" + paidDate[index] + "</td>";
results += "<td>" + paidTime[index] + "</td>";
results += "</tr>";
}
results += " </tbody>";
results += " </table>";
alert(results);
var div = document.getElementById("paymentDetails");
div.innerHTML = results;
}
The data gets displayed as follows:
Payment History
User VideoName Payment Date Time
43CA3KZXYQGBK Animal Series 14-01-2014 14:12:20
43CA3KZXYQGBKAnimalSeries10-01-201415:40:12
43CA3KZXYQGBKAnimalSeries10-01-201403:21:15
43CA3KZXYQGBKAnimalSeries10-01-201416:39:28
The XML Data:
<xml>
<payments>
<devicenumber>43CA3KZXYQGBK</devicenumber>
<videonumber>1234567</videonumber>
<paymentdate>2014-01-11</paymentdate>
<paymenttime>19:38:19</paymenttime>
</payments>
<payments>
<devicenumber>43CA3KZXYQGBK</devicenumber>
<videonumber>1234567</videonumber>
<paymentdate>2014-01-10</paymentdate>
<paymenttime>19:38:19</paymenttime>
</payments>
<payments>
<devicenumber>43CA3KZXYQGBK</devicenumber>
<videonumber>1234567</videonumber>
<paymentdate>2014-01-01</paymentdate>
<paymenttime>19:38:19</paymenttime>
</payments>
<payments>
<devicenumber>43CA3KZXYQGBK</devicenumber>
<videonumber>1234567</videonumber>
<paymentdate>2014-01-09</paymentdate>
<paymenttime>19:38:19</paymenttime>
</payments>
</xml>
What could i be doing wrong?
The closing tag for table is in the for-loop. You need to put it outside the for-loop:-
for (var index = 0; index < items.length; index++)
{
var deviceNumElement = items[index].getElementsByTagName("devicenumber")[0];
var VideoNumElement = items[index].getElementsByTagName("videonumber")[0];
var dateElement = items[index].getElementsByTagName("paymentdate")[0];
var timeElement = items[index].getElementsByTagName("paymenttime")[0];
if (deviceNumElement && VideoNumElement && dateElement && timeElement)
{
deviceNum[index] = deviceNumElement.firstChild.data;
videoNum[index] = VideoNumElement.firstChild.data;
paidDate[index] = dateElement.firstChild.data;
paidTime[index] = timeElement.firstChild.data;
results += "<tr>";
results += "<td>"+ deviceNum[index] + "</td>";
results += "<td>" + videoNum[index] + "</td>";
results += "<td>" + paidDate[index] + "</td>";
results += "<td>" + paidTime[index] + "</td>";
results += "</tr>";
}
}
results += " </tbody>";
results += " </table>";
alert(results);
var div = document.getElementById("paymentDetails");
div.innerHTML = results;
