Question

hello can anyone help me debug little error that my eyes seem to be skipping. error is: unexpected ( error. Are my array syntex correct?

function SourceClusting()
{
    // grabbing count
    var table = document.getElementById('OSDataCount');
    var counter= table.rows[1].children[0].innerHTML
    // putting all variable into arrays
    var latitude()
    var longitude()
    var i

    var marker =[];

    // placing values into arrays
    for (i=1;i == counter;i++)
        {
        longitude[i]=table.rows[i].children[6].innerHTML;
        latitude[i]=table.rows[i].children[5].innerHTML;

        marker[i]=new GMarker(new GLatLng(longitude[i],latitude[i])); 

        }

    var markerCluster = new MarkerClusterer(map, marker);


}

cheers

Answer 1

Quite a few things:

• You have to parseInt() the string you get from var counter = ..., as a string can’t be used in comparisons with integers the way you’d like.
• var latitude = () should be var latitude = [], as it’s an array, Don’t forget those semicolons!
• You usually use a lesser-than sign in a loop, not an equality sign ==.
• You can condense the loop by initializing i within it.

Try this new, possibly working code:

function SourceClusting() {
    // grabbing count
    var table = document.getElementById('OSDataCount');
    var counter= parseInt(table.rows[1].children[0].innerHTML, 10);
    // putting all variable into arrays
    var latitude = [];
    var longitude = [];

    var marker =[];

    // placing values into arrays
    for (var i = 0; i < counter; i++)
        {
        longitude[i]=table.rows[i].children[6].innerHTML;
        latitude[i]=table.rows[i].children[5].innerHTML;

        marker[i]=new GMarker(new GLatLng(longitude[i],latitude[i])); 

        }

    var markerCluster = new MarkerClusterer(map, marker);
