use of document.body.getElementsByTagName('*')

[tas2826]

Given the snippet below, let just say that elem[1] is a text input. How do I get the the type of input which would be "text", and the value that the text input contains?

var elem = document.body.getElementsByTagName('*');

var getIt = elem[1].id;

alert(getIt); //gives me the id
alert(getIt.type); //does not work, how do I get to type?
alert(getIt.value); //does not work, how do I get to value?

Thanks in advance,

Troy

What you have [!]will[/!] work if 'getIt' is a standard text input.

Use try/catch

try {
   if (getIt.type == "text") {
      window.alert(getIt.id + " is a text field!");
      // do whatever
   }
} catch (e) {
   // this probably wasn't a text field, or trying to
   // do getIt.type threw a JavaScript exception. The
   // property `e.message` will tell you the error
   window.alert(e.message);
}

...and it isn't... it's a string containing the ID.

My bad

var elem = document.body.getElementsByTagName('*');

var getIt = elem[1].id;

alert(getIt); //gives me the id
alert(getIt.type); //does not work, how do I get to type?
alert(getIt.value); //does not work, how do I get to value?

should be this.

var elem = document.body.getElementsByTagName('*');

var getIt = elem[1];

if(getIt.type == "text")
{
   alert(getIt.id);
   alert(getIt.type);
   alert(getIt.value);
}

This should work correct? If its a standard input that is.

Thanks,
Troy
