从haml link_to调用javascript函数

Question

I would like to invoke a javascript function (without JQuery) when the onclick even fires from a link_to tag in haml. How can I do this?

Answer 1

以下是使用haml中的Rails link_to的方法：

= link_to "my link", "", :onclick => "my_function(); return false"

Answer 2

I think this could work:

link_to "your link", href, :onclick => "jsFunction"

Or, doing everything JS side:

document.body.addEventListener('click',function(e)
{
    var target = e.target || e.srcElement;
    if (target.tagName.toLowerCase() !== 'a')
    {
        return e;//not clicked on link
    }
    //a link was clicked, maybe check class or id or other stuff to narrow it down
    //if a link you were interested in was clicked:
    return theClickFunction.apply(target,[e]);
},false);

Answer 3

纯粹的HAML相当于@ edouardbriere的答案：

%a{href: '#', onclick: 'my_function(); return false;'} my link

Answer 4

<a onclick="YOURMETHOD;"/>A link</a>

如果您还想阻止位置更改，请在方法调用后添加return false 。
