当值大于1时，执行此操作

Question

I have a variable named countTicked that is storing an integer of how many relatedBoxes there are on the page.

I need an if statement that does something when the value of countTicked is greater than 1.

if (!$(clickedCheckBox).is(':checked'))
{
     //do something
} 
else
{
    var selectedDots = $(currentMap).find('div.' + checkBoxID);
    var relatedCheckBoxes = $(selectedDots).attr('class');        
    var countTicked = $(relatedCheckBoxes).filter(':checked');

    if (countTicked > 1)
    {
        //do one thing
    } 
    else
    {
        //do something else
    }      
}

I have implemented the changes you guys have provided. But my second IF statement still doesnt work. What am I still doing wrong?

Answer 1

Just use this as if condition:

if (countTicked > 1)

countTicked contains an integer, no need to put it in a jquery object.

Answer 2

Why do use use the $ sign? what is relatedBoxes?

var countTicked = parseInt($(relatedBoxes).length);

if (countTicked > 1)
{
    //do something

} 
else
{
    //do something else
}

Update: you have to use the length to get the number of elements.

var countTicked = $(relatedCheckBoxes).filter(':checked').length;

Answer 3

it should be :

  var countTicked = parseInt($(relatedBoxes).length);

            if (countTicked > 1)
            {
                //do something

            } else
            {
                //do something else
            }

as you are using countTicked as variable. No need to use it as a jquery object

Answer 4

$(relatedCheckBoxes).filter(':checked') is a jQuery object, which has length property. So in order to know amount of ticked checkboxes, use

var countTicked = $(relatedCheckBoxes).filter(':checked').length

parseInt isn't obligated.
