Can someone please tell me how to compare elements in array with every other element. I mean in array arr = [a,b,c,d];, I would like to compare a with b,c,d , b with a,c,d, etc. And to do that dynamically, no mather of the size of the array.

Try this:
var a=["a","b","c","d"];
for(var i=0;i<a.length;i++){
for(var j=0;j<a.length;j++){
if(i!=j && a[j]===a[i]){
//match, do whatever you want
}
}
}

I have an object in Angular looking like this:
$scope.addEmployeeDepartments={ 5066549580791808=true, 6192449487634432=true, 7192449487634432=false}
How do I generate a comma-separated string like this
var ids="5066549580791808, 6192449487634432"
containing all the keys which are true ?
Btw, I am using underscore.js in other parts of my solution, so I don't know if that makes it easier.
thanks
Thomas

You can do this with reduce in one pass:
var collect_trues_in = function(a, v, k) {
if(v)
a.push(k);
return a;
};
var csv = _($scope.addEmployeeDepartments).reduce(collect_trues_in, [ ]).join(', ');

is it possible to convert a text from an input to a string or integer?
I have an input field, in which you can search a company:
<input type="text" id="company" name="company" />
Now I need the value as a string or int.
Thanks for you help.

Value of the input field is a string by default. You can convert it to an int by
parseInt(document.getElementById("company").value,10);

It is Simple stuff. You can convert by using parseInt() Function.
It will convert your string to Integer.
function convert()
{
var x=document.getElemenyById("company").value;
x=parseInt(x);
}

jquery version:
parseInt($( "#company" ).val(), 10);
plain javascript:
parseIntdocument.getElementById('company').value, 10);

I am new to jQuery. I have a text field and I want to validate this field so that it only takes character and alphanumeric values, however if you put in a numeric value it will show a message. How should I implement this?

$('#textfieldid').on('change', function(event) {
var text = $('#textfieldid').text();
//some validation code here
});
By the way, JQuery is a javascript library, not Java (which you have tagged).

Using regex, validations can be done.
var password = document.getElementB;
var letter = /[a-zA-Z]/;
var number = /[0-9]/;
if(number.test(password) && letter.test(password)){
//success
}else{
//error
}
Here password is the value which is returned from the field
