Create rows/columns dynamically in ASP.net with Javascript function

[Rambaldi]

Although i'm working on ASP.net, i think the problem i'm facing is related to my javascript function so i hope i create the thread in the right section.

My goal is to create a table dynamically, depending with the number of cameras i got. The code is:

 
    var tabela = "<table border=2 width='100%' heigth='100%'><tr>";
    var lastCol = 3;
 
    for (var i = 1; i <= nCam; i++)
    {
        if (i == lastCol)
        {
            if(i = nCam)
            {
                tabela += "</tr><tr><td><img src=\"http://server.ubiwhere.com/cgi-bin/nph-zms?mode=jpeg&monitor=" + i + "\" /></td></tr></table>";
            }
            else
            {
                tabela += "</tr><tr><td><img src=\"http://server.ubiwhere.com/cgi-bin/nph-zms?mode=jpeg&monitor=" + i + "\" /></td>";
            }
            lastCol = lastCol + 3;
        }
        else if (i = nCam)
        {
            tabela += "<td><img src=\"http://server.ubiwhere.com/cgi-bin/nph-zms?mode=jpeg&monitor=" + i + "\" /></td></tr></table>";
        }
        else
        {
            tabela += "<td><img src=\"http://server.ubiwhere.com/cgi-bin/nph-zms?mode=jpeg&monitor=" + i + "\" /></td>";
        }
    }
document.getElementById("montCam").innerHTML = tabela;
 

tabela --> a string that will have stored the whole table;
lastCol --> a flag i use to know when i am about to creat a third column, so i can after create another row;
nCam --> the number of cameras i got.

So my intention is increment on the string tabela each column and row according to the number of cameras, but what happen is that in 4 cameras, the webpage just show the last one :(

i put the alert() function to see what the string ‘tabela’ has and it show:

<table border=2 width='100%' heigth='100%'><tr><td><img src=\"http://server.ubiwhere.com/cgi-bin/nph-zms?mode=jpeg&monitor=4/></td></tr></table>

Why dont he increment the code that the compiler already passes through on the 'if' conditions?
I'm not good at javascript so i thought the code sintax maybe could be wrong. Someone can help me? Warn me if i wasnt too clear.

Thanks in advance.

On line 8 and 18, you're setting i to nCam instead of comparing. Use double equals ==.
