死灵法术：
并且没有 jQuery，需要这样的复选框结构：
<label>
<input type="checkbox" id="mytrackers_1" name="blubb_1" value="">--- Bitte auswählen ---
</label>
<label>
<input type="checkbox" id="mytrackers_2" name="blubb_2" value="7">Testtracker
</label>
<label>
<input type="checkbox" id="mytrackers_3" name="blubb_3" value="3">Kundenanfrage
</label>
<label>
<input type="checkbox" id="mytrackers_4" name="blubb_4" value="2">Anpassung
</label>
<label>
<input type="checkbox" id="mytrackers_5" name="blubb_5" value="1" checked="checked" >Fehler
</label>
<label>
<input type="checkbox" id="mytrackers_6" name="blubb_6" value="4">Bedienung
</label>
<label>
<input type="checkbox" id="mytrackers_7" name="blubb_7" value="5">Internes
</label>
<label>
<input type="checkbox" id="mytrackers_8" name="blubb_8" value="6">Änderungswunsch
</label>
