Checkboxes--number written to screen

srotondo · January 10th, 2005, 12:19 PM

Good morning.

I have a program in which I write various numbers of checkboxes to the user's screen. The number of checkboxes written varies depending on the content written from the database. The form will have all sorts of items written to it: checkboxes, dropdown lists, text boxes, etc.

Is there a way in JavaScript to "count" the total number of checkboxes written to the screen? I need to loop through all of the checkboxes that I write to the screen.

Thank you!

No direct way but:

Code:

function getInputsByType(Type)
{
  var colInputs = document.getElementsByTagName("input");
  var arrTargets = new Array():
  var sType = Type.toLowerCase();
  for (var i = 0; i < colInputs.length; i++)
  {
    var oInput = colInputs[i];
    if (oInput.type.toLowerCase() == sType)
    {
      arrTargets.push(oInput);
    }
  }
  return arrTargets;
}

then

Code:

 var arrCheckboxes = getInputsByType("checkbox")

or

Code:

var arrTextboxes = getInputsByType("text")
