Hi,
Lacking javascript knowledge, I just realized why my project has a bug.
I am using ASP to loop through a set of records while it creates URLs
with a querystring that has a single value pair. This URL needs to open
in a floating window if clicked. (this is for an administrator and so
opening a small floater gives them more efficient access to the data that
will be displayed). I now understand that because the ASP executes first,
that is why the querystring that shows up in all the URLs is the last one
thta was resolved in the ASP loop.
This is what I was using within my ASP loop.
<script LANGUAGE="JavaScript">
<!--
function win2()
{
window.open("admin_detail_contact_info.asp?id=<%=d bRecordset
("id")%>","Window2","menubar=no,scrollbars=yes,wid th=375,height=
520,toolbar=no");
}
//-->
</script>
And then
<a href="javascript:win2()" onMouseOver="self.status='Open A Window';
return true;"><%=dbRecordset("lastname") & ", " & dbRecordset
("firstname")%></a>
The above of course keeps repeating in the ASP loop as it should, but the
querystring of course is resolving to the last id resolved in the loop.
I have been searching and reading, but without javascript knowledge I am
not being able to resolve the above. Note that there is another javascript
on the page which forces me to have to use javascript for this. If I do
not, the anchor object will default to the other script because it is a
default for each row in the output. Only by having my URL controlled by
another javascript will it be available without also executing the default
script for the row. If I use a target instead, thereby opening an full new
window, both URLs open simultaneously. This is not an issue, it is an
explanation as to why I cannot just use a simple target and give up the
javascript defined window.
BACK ON TOPIC
I can see that there is a way to parse the querystring using javascript but
the examples are for querystrings with multiple value pairs. I am not able
to both pair that down and also make it work with opening a new window for
the client chosen URL. Can someone help me?
I believe that the following has some of what I need in it if it was
reduced to only resolving the one value pair since I do not need to hunt.
Can someone possibly remove all the code that is unnnecssary for my need
and maybe help me to apply that to creating the final URLs by parse the
querystring that the ASP loops makes and then appendeding that single value
pair to the javascript window.open function similar to or whatever is
needed, to the one posted above.
<script>
function PageQuery(q) {
if(q.length 1) this.q = q.substring(1, q.length);
else this.q = null;
this.keyValuePairs = new Array();
if(q) {
for(var i=0; i < this.q.split("&").length; i++) {
this.keyValuePairs[i] = this.q.split("&")[i];
}
}
this.getKeyValuePairs = function() { return this.keyValuePairs; }
this.getValue = function(s) {
for(var j=0; j < this.keyValuePairs.length; j++) {
if(this.keyValuePairs[j].split("=")[0] == s)
return this.keyValuePairs[j].split("=")[1];
}
return false;
}
this.getParameters = function() {
var a = new Array(this.getLength());
for(var j=0; j < this.keyValuePairs.length; j++) {
a[j] = this.keyValuePairs[j].split("=")[0];
}
return a;
}
this.getLength = function() { return this.keyValuePairs.length; }
}
function queryString(key){
var page = new PageQuery(window.location.search);
return unescape(page.getValue(key));
}
function displayItem(key){
if(queryString(key)=='false')
{
document.write("you didn't enter a ?name=value querystring item.");
}else{
document.write(queryString(key));
}
}
</script>
<body onload="displayItem('name');">
