以编程方式单击超级链接的不同方式？

Question

What are some other ways to programmatically click a text link on a page? The link does not have a ID and will not have one. example link will look like this:

<div unselectable="on" class="x-grid-cell-inner " style="text-align:left;">
<a href="file/files/now.pdf">Click Here</a>   
</div>

Here's one way I can do it but want to know more ways to click it.

var els = document.getElementsByTagName('a');
    for (var i = 0, l = els.length; i < l; i++) 
    {
       var el = els[i];
       if (el.text === 'Click Here') 
       {
           el.click()
       }
    }

Answer 1

It can't have an id? That would be the best route IMO. Second best approaches:

2. Assign a class, and look up by class

or

3. Assign an id or class to the parent object, and look up the first "a" child
