I have the following piece of code:
compareHtml += " </tr><tr>";
for (i = 0; i < compareArr.length; i++) {
compareHtml += '<td>' + compareArr[i].journaltitle + '</td>';
journalTitle.append('<span>' + compareArr[i].journaltitle + '</span> ');
}
And it creates a new span for each journalTitle. However, I want each new span to be created to have the ID "journalTitle1" "journalTitle2" "journalTitle3"....and so on.
Is this something that is possible? Currently they have no ID when created it is just a normal span.
You can do like following
compareHtml += " </tr><tr>";
for (i = 1; i < compareArr.length-1; i++) {
compareHtml += '<td>' + compareArr[i].journaltitle + '</td>';
journalTitle.append('<span id=journalTitle'+i+'>' + compareArr[i].journaltitle + '</span> ');
}

I have this for code for a data table, I made this to support a search function, but I can figure out how to set a table length. I want to set it to ten.
I want to add Array elements to the table.
Array elements are dynamic coming from the database. And i am creating the Row for adding the one row from the generated data and appending rowAfter to add the other array elements
Here is the code i have written -
var rowSpan = 0;
var rowSpan1 = 0;
for (element in data)
{
// get products into an array
var productsArray = data[element].products.split(',');
var QuantityArray = data[element].quantity.split(',');
var ChemistArray = data[element].Retailername.split(',');
var PobArray = data[element].Pob.split(',');
rowSpan = productsArray.length;
rowSpan1 = ChemistArray.length;
var row = '<tr>' +
'<td rowspan="'+rowSpan+'">' + data[element].date + '</td>'+
'<td rowspan="'+rowSpan+'">' + data[element].doctor_name + '</td>';
// loop through products array
var rowAfter = "";
for (var i = 0; i < rowSpan; i++) {
if(i == 0) {
row += '<td>' + productsArray[i] + '</td>';
row += '<td>' + QuantityArray[i] + '</td>';
} else {
rowAfter += '<tr><td>' + productsArray[i] + '</td><td>' + QuantityArray[i] + '</td>';
}
}
for (var k = 0; k < rowSpan1; k++) {
if(k == 0) {
row += '<td>' + ChemistArray[k] + '</td>';
row += '<td>' + PobArray[k] + '</td>';
} else {
rowAfter += '<td>' + ChemistArray[k] + '</td><td>' + PobArray[k] + '</td> </tr>';
}
}
row +=
'<td rowspan="'+rowSpan1+'">' + data[element].locations +'</td>'+
'<td rowspan="'+rowSpan1+'">' + data[element].area + '</td>'+
'</tr>';
$('#tbody').append(row+rowAfter);
So as per the code I can finely display ProductArray and Quantity Array
And But i am not able to display the Chemist array after one another.
In the above Image i want to display data( Kapila and Kripa below the Chemist column) Some where making issue with tr and td.
Any help would really appreciated.
Data is a JSON Response -
In my case, ChemistArray(Retailername in response) contains 4 names and POBArray 4 values.
You need to add an empty <td></td> as a "placeholder".
for (element in data) {
var productsArray = data[element].products.split(',');
var quantityArray = data[element].quantity.split(',');
var chemistArray = data[element].Retailername.split(',');
var pobArray = data[element].Pob.split(',');
// find the largest row number
var maxRows = Math.max(productsArray.length, quantityArray.length, chemistArray.length, pobArray.length);
var content = '';
var date = '<td rowspan="' + maxRows + '">' + data[element].date + '</td>';
var doctorName = '<td rowspan="' + maxRows + '">' + data[element].doctor_name + '</td>';
var locations = '<td rowspan="' + maxRows + '">' + data[element].locations + '</td>';
var area = '<td rowspan="' + maxRows + '">' + data[element].area + '</td>';
content += '<tr>' + date + doctorName;
for (var row = 0; row < maxRows; row++) {
// only add '<tr>' if row !== 0
// It's because for the first row, we already have an open <tr> tag
// from the line "content += '<tr>' + date + doctorName;"
if (row !== 0) {
content += '<tr>';
}
// the ternary operator is used to check whether there is items in the array
// if yes, insert the value between the <td></td> tag
// if not, just add an empty <td></td> to the content as a placeholder
content += '<td>' + (productsArray[row] ? productsArray[row] : '') + '</td>';
content += '<td>' + (quantityArray[row] ? quantityArray[row] : '') + '</td>';
content += '<td>' + (chemistArray[row] ? chemistArray[row] : '') + '</td>';
content += '<td>' + (pobArray[row] ? pobArray[row] : '') + '</td>';
// only add "locations + area + '</tr>'" if it is the first row
// because locations and area will span the whole column
if (row === 0) {
content += locations + area + '</tr>';
} else {
content += '</tr>';
}
}
$('#tbody').append(content);
}
content += '<td>' + (productsArray[row] ? productsArray[row] : '') + '</td>'; is just a short-hand for
content += '<td>';
if (productsArray[row]) {
content += productsArray[row];
} else {
content += '';
}
content += '</td>';
If there is item in the productsArray[row], let's say productsArray[0], which is 'Sinarest', then productsArray[row] would be truthy. Else, if there is no more products in the array, such as productsArray[3] will gives us undefined, which is a falsy value and the corresponding conditional will be ran.
i have this code:
for (var i = 0; i < data.times.length; ++i) {
var time = formatTime(data.times[i].time);
tableContent += '<tr><td>' + data.times[i].destination.name + '</td><td id="appendLate' + i + '">' + time + '</td><td>' + data.times[i].track + '</td><td>' + data.times[i].train_type + '</td><td>' + data.times[i].company + '</td></tr>'
// laat vertragingen zien (BETA)
if (data.times[i].delay / 60 >= 1) {
$('#appendLate' + i + '').append("+" + data.times[i].delay / 60).addClass("late");
}
}
table.html(tableContent);
}
The if statement appends stuff and adds a class. i know it wont work like this.. but i cant seem to get how it WIL work.. Can some one help?

Well, you're basically almost there. The right way to do it is to build the entire string before doing any DOM manipulation, since DOM operations are very slow (relatively).
Let's say your index.html looks like:
<html>
<head>
<title>Cool site!</title>
</head>
<body>
<table id="myCoolTable"></table>
</body>
</html>
Then your JavaScript simply becomes:
var tableContent = '';
for (var i = 0; i < data.times.length; ++i) {
var time = formatTime(data.times[i].time);
tableContent += '<tr>'
+ '<td>' + data.times[i].destination.name + '</td>';
if (data.times[i].delay / 60 >= 1) {
tableContent += '<td id=\'appendLate\'' + i + ' class=\'late\'>' + time + '</td>' + '+' + (data.times[i].delay / 60);
} else {
tableContent += '<td id=\'appendLate\'' + i + '>' + time + '</td>';
}
tableContent += '<td id=\'appendLate\'' + i + '>' + time + '</td>'
+ '<td>' + data.times[i].track + '</td>'
+ '<td>' + data.times[i].train_type + '</td>'
+ '<td>' + data.times[i].company + '</td>'
+ '</tr>';
}
$('#myCoolTable').html(tableContent);
What this does is build the HTML for the entire table. Then update the table only once. Hope it helps!
I have below line in my js code. i runs from 0 to 2. I want to put a custom text in place of: ' + info[i] + ' for each of the i's(over iterations of i). How do I do that?
for(var i=0; i < origins.length-1; i++) {
var results = response.rows[i].elements;
output += '<tr><td>' + info[i] + '</td><td>' + origins[i] + '</td><td></td><td>' + destinations[i+1] + '</td><td></td><td>' + results[i+1].distance.text + '</td></tr>';
}
. I want to put a custom text in place of: ' + info[i] + ' for each of the i's(over iterations of i).
Not sure what is "custom text" but assume your custom text should be in an array:
var customText = ["Custom text for i=0",
"Custom text for i=1",
"Custom text for i=2"];
for(var i=0; i < origins.length-1; i++) {
var results = response.rows[i].elements;
output += '<tr><td>' + customText[i] + '</td><td>' + //....
}
Also how to align the out-put of the code at the center of my webpage?
This is connected to CSS rather than with JS. Use CSS property text-align: center for a table, div or wharever you want to center.
If the custom text isn't in a variable, just put it directly into the HTML that you're generating:
output += '<tr><td>Custom Text</td><td>' + origins[i] + '</td><td></td><td>' + destinations[i+1] + '</td><td></td><td>' + results[i+1].distance.text + '</td></tr>';
I am creating a table dynamically in a return statement from ajax. But I see only one row of the table, although debugger shows data.length as 4. How do I correct the recreating of table?
// using ajax return to recreate a table
// ...
if (data.length > 0) {
for (var i = 0; i < data.length; i++) {
var $mytablerow = $(
'<table>' +
'<tbody>' +
'<tr>' +
'<td id="td' + data[i].Value + '" >' +
data[i].Text +
'</td>' +
'</tr>' +
'</tbody>' +
'</table>'
);
}
}
var $mylst = $("#Userslist");
$mylst.html($mytablerow);
// ....
using ajax return to recreate a table
...
if (data.length > 0)
{
var $mytablerow = '<table><tbody>';
for (var i = 0; i < data.length; i++)
{
$mytablerow += $(
'<tr>' +
'<td id="td' + data[i].Value + '" >' + data[i].Text + '</td>' +
'</tr>');
}
$mytablerow += '</tbody></table>';
}
var $mylst = $("#Userslist");
$mylst.html($mytablerow);
....
I think you should use a variable outside the loop. For example:
if(data.length > 0) {
var $myTable = '<table><tbody>';
for (var i = 0; i < data.length; i++) {
$myTable += '<tr><td id="td' + data[i].Value + '" >' + data[i].Text + '</td></tr>';
}
$myTable += '</tbody></table>';
}
var $mylst = $("#Userslist");
$mylst.html($myTable);
You have problem in your script. To fix this problem replace by this script:
if (data.length > 0)
{
var $mytablerows = '<table>' + '<tbody>';
for (var i = 0; i < data.length; i++) {
$mytablerows += '<tr>' +
'<td id="td' + data[i].Value + '" >' + data[i].Text + '</td>' +
'</tr>';
}
$mytablerows += '</tbody>' + '</table>';
var $mylst = $("#Userslist");
$mylst.html($mytablerows);
}
That looks like you are creating a single row table each iteration and then only adding the last table you create. You need to create the table stuff once and then iterate to create the rows.
