Extract Value From Multiple Tags

[JBorges]

Hi,

I'm designing a Bible for iPhone and use Javascript to extract a verse into a label when the verse is touched. That's why I'm asking for help in this forum.

A typical HTML file look like this:

<a href="" id="1:1">Now these are the names of Israel’s sons who came into Egypt with Jacob; each man and his household came:</a>
<a href="" id="1:2">Reu´ben, Sim´e·on, Le´vi and Judah,</a>
<a href="" id="1:3">Is´sa·char, Zeb´u·lun and Benjamin,</a> 
etc...

with this code I can extract a verse into a label

document.getElementsByTagName('a')[0].innerHTML;

When I implement the above JS code into my action in my iPhone app it only extracts the text of the first verse. My question is, how can I extract any given verse into a label? What does the JS code look like?

document.getElementsByTagName('a')[[red]0[/red]].innerHTML;

Change the value between brackets to whatever number your verse is.

0 refers t0 the first link it finds, 1 would be the next one etc...

Yes that is true but that would require a set of 100s lines of document.getElementsByTagName('a')[0].innerHTML;
document.getElementsByTagName('a')[1].innerHTML;
document.getElementsByTagName('a')[2].innerHTML;
etc...

But I'm looking for a way for JS to extract the verse no matter what verse I press.

I'm thinking that [0].innerHTML should be a global variable like .innerHTML. But I'm not sure how that is accomplished.

Any ideas?

If you are using an onClick event of the link you can use the "this" reference to get the link that was clicked its innerHTML.

For instance:

<a href="" id="1:1" [red]onClick="get_line(this);"[/red]>Now these are the names of Israel's sons who came into Egypt with Jacob; each man and his household came:</a>
<a href="" id="1:2" [red]onClick="get_line(this);"[/red]>Reu´ben, Sim´e·on, Le´vi and Judah,</a>
<a href="" id="1:3" [red]onClick="get_line(this);"[/red]>Is´sa·char, Zeb´u·lun and Benjamin,</a>

get_line(lineObj){
var label= lineObj.innerHTML;
}

Thanks.

I'll see if I can embed it in my iPhone app.
