Retrieve Parameter from location bar

TheMSsForum.com: The Microsoft Software Forum

Hi Everybody

I have an Access database that passes a Parameter to a web page
something like this.
http://localhost/index.htm?paramName=1234-54321

I want to be able to retrieve the parameter (In this example
1234-54321) and pass it to a text box on a form. Something like this.

<form name="form1" id="form1" method="post" action="">
<input type="text" name="txtinput" value= "Param" />
</form>

Any help gratefully received

Try getting window.location.href in your script. Should return your
http://localhost/index.htm?paramName=1234-54321; then you can parse it
to get whatever you need...

There might be an easier way, but I don't recall right now...

Hi Marcello

I am not too familiar with javascscipt yet but I have found this coding
that almost does what I want but I am not fluent enough with javascript
to achieve the effect I want.........which is to have a text box on the
form which receives the # 1234-54321 from
the http://localhost/index.htm?paramName=1234-54321...Url

Thanks for the prompt reply

Bob

var pairs = qString.split(/\&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/\=/);
getVars[nameVal[0]] = nameVal[1];

return getVars;

Try this:

<script>
function GetQSVal(pName) {
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/\&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/\=/);
if(nameVal[0]==pName) return nameVal[1];
}
return "";
}

function popText(){
var v = GetQSVal("paramName");
document.getElementById("idTextInput").value = v;
}

</script>

<body onload="popText();">
....

The type attribute is required:

<script type="text/javascript">

> function parseGetVars() {

I'd rather call it 'getSearchParams'.

> var getVars = new Array();

This function uses an array like an ordinary object, so it may as well
use one (unless you want to use its array-ness for something else):

var getVars = {};

> var pairs = qString.split(/\&/);

To get a particular parameter value, you can do:

var searchParams = getSearchParams();
var paramValue;
if ( (paramValue = searchParams[paramName]) ){
// do something with paramValue
} else {
// paramName was not in the searchstring
// deal with it...
}
