So I have the following divs

```
    <div id="az" class="d_1" value="data1"></div>
    <div id="az" class="d_2" value="data2"></div>
    <div id="by" class="d_3" value="data3"></div>
    <div id="az" class="d_4" value="data4"></div>

```

how can I check **only** if `az` divs are clicked without adding `onClick="reply_click(this)"` to every div?
