disabling text fields/onblur

Is there a way of disabling a text field (disabled) or using the onblur function without blurring the text within it?

Thanks

was doing it wrong...

<input type="text" value="valuestuff" onchange="this.value='valuestuff';">

A couple of other ways...

<input type="text" value="valuestuff" readonly="true" />

<input type="text" value="valuestuff" onchange="this.value=this.defaultValue" />
