Question

I have this

<div id="mainDiv">
    <input type="text" value="Here is the text" />
</div>
<input type="button" value="Push" onclick="changeText()">

When I push the button I want to change the value from textfield.

Only this value I want to be changed because in my page there are a lot of textfields but those values must remain unchanged.

<div id="mainDiv"> 
<input type="text" value="Here is the text" /> 
</div> 
<input type="button" value="Push" onclick="document.getElementById('mainDiv').children[0].value='asd'">
