使用 onclick 制作可点击的链接但没有 href=#？

Question

I have a set of clickable identifiers on my page. About hundred, like 'cat1', 'cat2', 'dog1', 'dog2', 'dog3' etc. Then I have a function IDClick(id) {}

I need those identifiers clickable in HTML, to achieve that I used <a> tag with onclick

<a onclick=IDClick(id)>id</a>

now it works, but the cursor will not change when it is hovered over the clickable element.

So I try to add href=#

<a href=# onclick=IDClick(id)>id</a>

Now the cursor is OK, but when I click the item, the URL in the browser location bar will change. This is not desired.

How to get the mixed behavior?

I do not need underline as well.

Answer 1

You need to stop the browser from doing it's default action.

<a href="#" onclick="IDClick(id);event.preventDefault();">id</a>

When you click on a link, the default action is to go to that address. event.preventDefault(); prevents the browser from doing the default action.

This is a significantly better solution for accessibility. Quoting @aij's comment above : "using CSS makes it look ok, but still leaves it inaccessible from the keyboard (ie, tab will never focus the link)".

Answer 2

You can use CSS to force the cursor to change on hover of the clickable element:

.myClickableThingy {
    cursor: pointer;
}

And then you can switch back to <span> s or whatever of element you were using before <a> tags.

Answer 3

Give your anchor element a class and style it to achieve what you need:

<a class='kinda-link' onclick='whatevs()'>Hi I'm a kinda-link</a>

And your css:

a.kinda-link:hover { cursor: pointer; }

Answer 4

Recently I use clickable spans in most cases.

 Some text with some <span onclick="alert('hey there')" style="color: blue; cursor: pointer">part</span> that is clickable.

Answer 5

Use return false; in the IDClick handler function.

<a href=# onclick=IDClick(id)>id</a>

IDClick() {

   ...
   return false;

}
