index order of an object in an array

Copy linkTweet thisAlerts:
May 20.2004

I have

<a href=”#” onclick=”showOrder(this)”>zero</a>
<a href=”#” onclick=”showOrder(this)”>one</a>
<a href=”#” onclick=”showOrder(this)”>two</a>

In code. these objects are elements in an array:

hrefArray = document.getElementsByTagName(‘a’);
thus i have 3 elements (objects)
hrefArray[0]
hrefArray[1]
hrefArray[2]

how can return on click, in function showOrder(), the order of these elements (0,1 or 2)?

function showOrder(which){
var order = which.[color=red][i]what_attribute_here?[/i][/color];
alert(order);
}

?

@KorauthorMay 20.2004 — well, I solved the problem by compare the two objects

for(i=0;i<hrefArray.length;i++){

if(which==hrefArray[i]){alert(i)}

}



Still I wonder if there is a property or method to return directly the order



if there is

document.getElementById('theid').id

could not be something like

document.getElementsByTagName('tagname')[0].[i]order[/i]?

@FangMay 20.2004 — You can't; the only attribute that is defined is [I]href[/I](and the onclick itself), so "which" returns the url.

Easy enough using the DOM, as you did, to help you.
