button linke value

[terti]

Hi there, newbie here.

appologies if this is OT. (DOM based)

I have a button defined in the html as follows:

<input name="btnPay" value="Continue with payment"
onclick="document.location='LoadPayment.asp?TPID=23448&RGID=7'"
type="button"><br>

How can I extract the document.location portion from the html?
IOW. 'LoadPayment.asp?TPID=23448&RGID=7'

Many TIA
T

I don't know why you need to do it, it's a bit "ugly".. BTW, a method could
be:

<input id="btn-pay" name="btnPay" value="Continue with payment"
onclick="document.location='LoadPayment.asp?TPID=23448&RGID=7'"
type="button">

<script type="text/javascript">
function getPayURI(){
var btn=document.getElementById("btn-pay"),
txt=btn.getAttribute("onclick"),
res=[];

txt=typeof txt=="function"?txt.toString():txt;

res=txt.match(/document\.location='([^']+)'/);

return (res && res[1])?res[1]:null;
}

alert(getPayURI())
</script>

Thanks for the reply,

I can not alter the html that is sent to me so the getElementById() may
not work
What I really wanty to do is to simmilate a button being pressed
without user intervention.


The reason why I wanted the link was so that I could follow it with a
get() method.
Is there a way to simmulate a butted pressed event ?

thanks

This is not a problem, you can use getElementsByTagName instead:

var btn=document.getElementsByTagName("btnPay")[0]

What I really wanty to do is to simmilate a button being pressed
without user intervention.

You can try with click() method, then.

document.getElementsByTagName("btnPay")[0].click();

You don't need getElementById(). The following code will loop through all
input's on the page (in reverse order btw, that 's usually faster this way)
and activite the first it finds that points to said url:

var a=document.getElementsByTagName('input');
var i=a.length; while(i--) {
if( a.type.toLowerCase()==='button'
&& a.onclick.indexOf('LoadPayment.asp')>0 ) {
a.click();
}
}

Are you sure this is within the law?

Many thanks for the help
the .click() method gets the job done.

Argh, sorry.. I was misunderstanding:

var btn=document.getElementsNames("btnPay")[0]

You can use document.getElementsNames("btnPay")[0] for obtain the reference
to button.. The loop is not necessary:

document.getElementsNames("btnPay")[0].click()

You can use document.getElementsNames("btnPay")[0]

The name is getElementsByName, but considering that this control is in a
form,

document.forms[...].elements['btnPay']

where the ellipsis is either a number or a string containing the name or
id of the form, would be better.

yes, I misunderstanding again.. unfortunately, I've made a copy&paste in
my post.. but the concept is the same.

but considering that this control is in a form,

well, I don't know if the control is in a form. In the post of terti the
code is out of context.
So, I wrote a code that works with or without a form parent element.

document.forms[...].elements['btnPay']

In that case you can use directly:

document.forms[...].btnPay.click();

or

document.forms.nameOfForm.btnPay.click();

as well.

P.S.
Sorry for my english, I know is not very good.

Re-examining the original post, it might not be. The text of the button,
"Continue with payment", would suggest that it is a submit button, but
it's not.
