HI --
ich bin Neuling in Javascript und könnte mal ein wenig Unterstützung gebrauchen. Ich habe ein Eingabefeld, dessen Einträge per Klick auf einen Button in eine Textbox geschrieben werden sollen.
Leider hat das nach mehreren Versuchen nicht geklappt. Hier mein Ansatz:

document.getElementById('eingabefeld').value = document.getElementById('textfeld').value

Kann mir hier vielleicht jemand kurz helfen.

Code:

	function dialog(){
		
		//Eingabe wird in variable b gespeichert, die dann die einzelnen Wörter in ein Array 		speichert
		var b = document.getElementById('eingabefeld').value;
		var temp = new Array();
		temp = b.split(' ');  
		
		
		// hier wird das 
		for(int i=0; i < temp.length; i++) {

		 for(int n=0; n < conj1.length; n++) {
		   if(temp[i] == conj1[n])
			temp[i] = conj2[n];
		 }
