I have a page that contains several HREFs. Each HREF that I'm
interested in has a common parameter (parmX). Does anyone have a script
example on how to find-and-replace parmX with parmY?
I'm assuming that I'd need to do this in the onload event - but I don't
know much about Javascript.
Please Help!
Thanks

<a href='...'>...</a> usually contains just a URL.
Do you mean that?
Show us some code, the relevant part, that is.

Yes - thats what I mean. The URL in the <a Href= tag may contain a
parameter &stream= 1. I want to replace every occurrence of that
with a new parameter &stream= 0.
I wrote a test script:
OnLoad() {
var frm = document.forms[0];
var cnt = 0;
// loop through all elements
for (i=0; i<frm.length; i++) {
// Look for hrefs with the stream=1 parameter
if (frm.elements[i].name.indexOf(' &stream= 1') != -1) {
cnt = cnt + 1;
alert('Found HREF w/stream=1[' + cnt + ']');
}
}
}
return;
}
Followed by a call to the function in the Body Onload event
</head>
<body onload="OnLoad( );" marg...
However, I'm getting an error - so I assume that my syntax or something
is wrong. I just wanted to start trying to access the function and
report on hits. I'll have to tackle the data replacement once I get
over this hurdle...
Thanks

Bad name for a function
function searchHrefForSt r(Str){ var frm = document.forms[0];
Surely you mean "document.links " ?
var cnt = 0;
// loop through all elements
for (i=0; i<frm.length; i++) {
for(var i=0;i<document. links.length;i+ +){
// Look for hrefs with the stream=1 parameter
if (frm.elements[i].name.indexOf(' &stream= 1') != -1) {
if (document.links[i].href.indexOf(S tr) != -1{
cnt = cnt + 1;
Not neccesary
alert('Found HREF w/stream=1[' + cnt + ']'); alert('Found HREF w/'+Str'+'[' + (cnt++) + ']');
}
}
}
return;
why return? }
Followed by a call to the function in the Body Onload event
</head>
<body onload="OnLoad( );" marg...
<body onload="searchH refForStr('stre am=1');"
Not tested.

Let's make this compact:

Very good, not sure that will replace "&" though.

If you are not sure, why not test it, it's your code anyway.
& should not be necessary in the result, so try:
/[\?\&](amp;)?stream=0 (\&||$)/

Thanks for the help! I really appreciate the code example.
I'll test it today and let you know it works.

Ok, so what I am attempting to accomplish is to replace my table-based

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
