Question: I have reviewed several responses to this matter however I can not find an error in my code.

```
button1.addEventListener('click',function(e)
{
    pesquisa.open("POST","http://10.0.2.2/jobfinder/teste.php");
    var params = {
        pesquisa: box1.value
    };
    pesquisa.send(params);
});

```

Answer: 
Vera, 

Unexpected end of input error usually means there is a an unclosed parenthesis or bracket. Please post the full sample of code you are executing and I can find the problem for you.
```
button1.addEventListener('click',function(e) )
{

```

you were missing a closing parenthesis after `function(e)`
