I've seen this how to export javascript array info to csv on client side
which works fine for me but there's a thing that annoys me.
in CSV you can seperate the strings in differents cell with a simple comma (,) so you got like:
[["name1", "city_name1", ...], ["name2", "city_name2", ...]]
and name1 and city_name1 are in the same cell. Is there a way to get them in two different cells in Excel with JavaScript?
When you parse a CSV in JavaScript, the array of arrays that results is not an array of cells. It is an array of rows where Array[0] is a row and Array[0][0] is a cell. What you have here is exactly what you are already asking for- name1 in row 1 cell 1, and name2 in row 2 cell 1.
Why not just set your data up in a hidden html table? The table will pop into the csv complete with your css styles. So if you want name1 and city_name1 in cells 1 and 2 of row 1, and then name2 and city_name2 in cells 1 and 2 of row 2, set the table up like that.

Maybe tittle is not too descriptive, but how do I get this kind of result
var string = 11+'-'+10
// expected result 11-10
console.log(string);
Every time I try to do the above I get 1, or whatever the result of the subtraction is
I will be a little bit clear about this. What I want to do with this is generate a button with onclick like this:
onClick = method(1,[11-10, 12-10])
method(id,...array){
console.log(array)
//result [1,2]
}
even if inspecting the button actually shows the correct output
In your first example, you use
11+'-'+10
In the second one, you use
11-10
There is a clear difference
Using the first method in the second code will work as expected
method(1,[11+'-'+10, 12+'-'+10])
To make it shorter just use strings
method(1,['11-10', '12-10'])

I wanted to get a radar chart using the following query. But the graph is not displayed. What is the problem?
str= "{type:'column',showInLegend: true,name:'"+userdet.getCompname()+"'"
+ ",dataPoints:[{y:"+aa+",label:'self'},{y:"+r+",label:'average'},{y:"+bb+",label:'superior'}]},";
sb.append(str);
I am getting data from the the following table. "aa" is self marks, "bb" is superior marks and "r" representing the average marks. "userdet.getCompname()" will retrieve the competency name from the table report. table report
The LIMIT keyword isn't allowed in an INSERT statement. It limits the number of rows returned by a query.
Your insert query is only ever going to insert 1 or 0 rows (since you only have one set of values but might hit an error if you duplicate a unique key).
If you want to limit the number of rows then you can do two queries:
Count the number of rows (with a SELECT)
Insert the new row (if the count isn't too high)
You should wrap the two queries in a transaction to avoid race conditions.
A cursory Google suggests that there might be database specific approaches to doing an insert if with a row count, but they will depend on whatever database server you are using (and didn't mention in the question).
The Limit 5 is for retrieving the data i.e. it will return 5 rows. I think you dont want to add any rows where there is already 5 rows inserted. You can check first the count of rows in table and after that you can add when count is less than 5.

I have three select lists that are filled with table names, column names and attribute names. I push them to a variable like this:
data.forEach(function(field){
fieldList.push(field);
But if I change a select list it adds all the column names of the second table to the array like this:
Here u you can find an exmample of what I want.
If you simply want data of the last selected table, clear array on your event.
fieldList = [];
data.forEach(function(field){
fieldList.push(field);
}
I fixed the problem. Just needed to add this line infront of the code:
fieldList.length = 0; . This line empty's the array before it gets filled again.

Using Javascript, Html and BFO (Big Faceless Org) PDF Generator, I need to create a table with fixed number of rows for every page in a sales order. Basically, the table should consist of fixed 10 rows, however rows populated with information may only be 1 or 2 rows. The other rows will be empty.
Anyone can help?
Currently all I have is:
for(I=0;i<=salesitem.length;i++){
document.write('<tr><td>salesitem[I]</td></tr>');
}
That generates one td row for every sales item. However, I want a fixed 10 rows in the table.
There are several issues with the tiny piece of code you've supplied...
javascript is case sensitive, therefore I and i are different variables
looping from 0 to i<=salesitems.length will end in an error, because if length is 10 and you use salesitem[10] it will fail (arrays are 0-based, and therefore an array with length of 10 has items 0 to 9)
I believe you think that salesitem[I] will process like PHP, it won't. PHP allows you to use echo "print this $varName", javascript simply doesn't allow that.
Try something along these lines...
for (i = 0; i < salesitem.length; i++) {
document.write('<tr><td>' + salesitem[i] + '</td></tr>');
}
for (i = salesitem.length; i < 10; i++) {
document.write('<tr><td></td></tr>');
}
The first loop will display everything in your array (including any entries over 10)
The second loop will display lines to complete the table (if there are less than 10 entries)
Try this.
for (var i=0;i<10;i++) {
document.write("<tr>");
//This will depend entirely upon what conditions have to be met
//in order for you to display the content of each row
if(variable == 'condition') {
document.write("<td>content</td>");
}
document.write("</tr>");
}

I am trying to create an array from a text field. I need to paste fifty lines into a text field. Then convert the lines to an array, with each line being a different element in the array.
Given an input field like this:
<textarea id="myInput"></textarea>
You can get the value from the text field as follows:
var myValue = document.getElementById("myInput").value;
And then split it like this
var myArray = myValue.split("\n");
