mein Code:
function checkFormFieldIsPositiveInt(formFieldID)
{
if((formFieldID == "[object KeyEvent]") || (formFieldID == "[object KeyboardEvent]"))
{
formFieldID = formFieldID.target.id;
}
if(formFieldID == "[object Event]")
{
formFieldID = formFieldID.srcElement.id;
}
for(i = 0; i < document.getElementById(formFieldID).value.length; ++i)
{
alert('Event ausgelöst');
if((document.getElementById(formFieldID).value.charAt(i) == ".") || (document.getElementById(formFieldID).value.charAt(i) == ",") || ((document.getElementById(formFieldID).value.charAt(i) < "0") || (document.getElementById(formFieldID).value.charAt(i) > "9"))) {
document.getElementById(formFieldID).style.border = "thin solid #FF0000";
break;
}
else if((document.getElementById(formFieldID).value.charAt(i) == " ") || (document.getElementById(formFieldID).value.charAt(i) == "") || (document.getElementById(formFieldID).value == ""))
{
document.getElementById(formFieldID).style.border = "thin solid #000000";
}
else
{
document.getElementById(formFieldID).style.border = "thin solid #000000";
}
}
}
arrayEventListeners = new Array("field1#keyup#checkFormFieldIsPositiveInt","field2#keyup#checkFormFieldIsPositiveInt");
function addEventListeners(arrayEventListeners) // v. 1.0.3
{
// arrayEventListeners: "elementID#shortEvent#funtionName
for(var i in arrayEventListeners)
{
var arrayEventListener = arrayEventListeners[i].split("#");
var functionReference = window[arrayEventListener[2]];
