我有一个html表单和一个“提交”按钮。我有两个标签，我想做不同的事情。提交时，一个选项卡应转到一个链接，而另一选项卡应将表单带到另一个链接。 这是我的小提琴，以显示我正在使用的工具：
https://jsfiddle.net/4s8qevz7/
我已经尝试将动作链接到（到目前为止）通用链接。但是没有运气。
<form style="margin-top:40px;" id="search-box" action="">
<div class="search-tab" data-search-type="catalog" action="http://catalog.com/" onClick="changePlaceholder(this)">Catalog </div>
<div class="search-tab selected" data-search-type="website" action="https://www.google.com/"onClick="changePlaceholder(this)">Website </div>
我的预期结果将取决于活动选项卡，单击“执行”按钮时表单将尊重该结果。

1）以表单提交方法调用preventDefault（）
2）从event.target获取活动标签
3）调用form.submit，并根据活动选项卡使用正确的选项。

我无法让您的jsfiddle工作，但是这里有一个示例：“在一个表单中，一个按钮执行2个操作”。如果选中此复选框，则操作将转到 bing.com ，否则将转到 Wikipedia 。您的if语句可以按照Dov Rine的建议使用currentTarget，而不是使用复选框动态更改表单操作。
function ActionSelect() {
if (document.getElementById('bing').checked) {
document.getElementsByTagName('form')[0]['action'] = 'https://bing.com';
}
}<form style="margin:40px 50px;" action="https://www.wikipedia.org">
Choose your form action:<br/>
<input type="checkbox" id="bing"> Bing
<p>
<button type="submit" onclick="ActionSelect()">Submit</button>
</p>
</form>
