javascript - 如何在表单元素中将按钮标记为事件 onclick

Question

如何使用 Onclick 激活输入按钮？

<div class="paForm-right">
    <form onsubmit="" name="form1" id="form1" method="post">
        <input type="submit" class="paForm-choose" id="paForm-bottom-vk" value="Visitenkarten" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-briefbogen" value="Briefbogen" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-flyer" value="Flyer" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-faltblaetter" value="Faltblätter" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-einzelblaetter" value="Einzelblätter" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-plakate" value="Plakate" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-postkarten" value="Postkarten" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-prospekte" value="Prospekte" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-kataloge" value="Broschüren usw." name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-mappe" value="Mappe" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-buch" value="Bücher" name="submit" />
        <input type="submit" class="paForm-choose" id="paForm-bottom-calender" value="Kalender" name="submit" />
        <input type="hidden" name="value[Produkt]" id="senden" value="Detailanfrage" />
    </form>
    <br />
</div>

这是我的 CSS...但是事件背景不起作用...

    input.paForm-choose:hover 
background-color:#D10C2D;


#paForm-bottom-vk 
background-image:url(../Icon_Visitenkarte_HG-Trans.png);

#paForm-bottom-vk:hover 
background-image:url(../Icon_Visitenkarte_HG-Trans.png);


#paForm-bottom-vk:active 
background-image:url(../Icon_Visitenkarte_HG-active.png);

Answer 1

这是一个FIDDLE使用你的代码，除了我在你的行前面放了一个“#”，上面有 :active。

:active 仅在按下键时显示，而不是在释放键时显示。因此，当您按住该键时，您可以看到米老鼠。

如果您要在按下不同的键之前更改它，则必须更改 js 代码。

CSS

#paForm-bottom-vk:active {
background-image:url('http://i.imgur.com/1Xm81k2.jpg');
}
