我需要禁用上传按钮.这是可能的？

如果选中或不选中复选框,我需要启用或禁用表单上的引导提交按钮

echo "<div class='panel panel-danger'><div class='panel-heading'>OBSERVACIONES</div><div class='panel-body'>";
echo "<div class='input-group'>";
echo "<label class='checkbox-inline'><input type='checkbox' name='visto' id='visto' value=''> Visto bueno del Responsable</label>";
echo "</div>"; 
echo "</div>"; 

...

echo "<input type='submit' class='btn btn-primary' value='SAVE' name='grabaperaus' formaction='update.php'>";
