getElementsByName returns list of matching name elements. you need to specify index of element you want to access. like this document.getElementsByName('test['+count+']')[0].value;

var count='0';
var value= document.getElementsByName('test['+count+']')[0].value;
alert(value);

<input type="hidden" value="4" name="test[0]">
