Using several techniques you can pass values from one page to another by creating links with parameters.

Portal

• Create a Portal shortcut and associate the link with that shortcut.

/urltopage?parameter1=@variable1@

User and Company variables can be used to pass the current logged in user details and their company details.

Application

• Create a Custom Field of the type Read Only - System Variables with one of the following.

Display as button

<input type="button" class=Button value="Button Label" onClick='parent.location.href="/urltopage?parameter1=@variable1@"'/>

Display as hyperlink

<a href="/urltopage?parameter1=@variable1@">Click Here</a>

Parsing Parameters

On the receiving page the parameters can pre-populate a form or an html element which resides on that page. In order to achieve this the following javascript functions can be used. Place the following first function in the head of the html.

function getParams() {
var idx = document.URL.indexOf('?');
var params = new Array();
if (idx != -1) {
var pairs = document.URL.substring(idx+1, document.URL.length).split('&');
for (var i=0; i<pairs.length; i++) {
nameVal = pairs[i].split('=');
params[nameVal[0]] = nameVal[1];
   }
}
return params;
}
params = getParams();

Place the following second functions in the body.

Form Field Population

<script>

var para1=document.getElementById('field1');
para1.value = unescape(params["parameter1"]);

</script>
