Pratap,
PASSING PARAMETERS:
this is very easy to do - you may use cookies for this task. You talking about dialogs - therefore you talking about client-side logic. In this case cookies is very popular mechanism to use.
1 - STEP - put data into cookie on 1st page
document.cookie="chosen="+value;
2 - STEP - retrieve data from cookie on another page/window
When you put data from one window/dialog into cookie, then you get get it using, for example, similar logic:
//prepare variable to get value from cookie
var myData = '';
//read all values from cookie
var coo_str = document.cookie;
//split values into array
var coo_arr = coo_str.split(";");
var tmp = null;
//running through array until find our data
var coo_str = document.cookie;
var coo_arr = coo_str.split(";");
var tmp = null;
for(var i=0; i<coo_arr.length; i++) {
tmp = coo_arr[i].split("=");
if(tmp[0].trim() === 'chosen') { // in this example - we looking for variable named "chosen"
myData = tmp[1].trim();
break;
}
}
RENDERING DIALOG WINDOW:
Assuming you decide to render from UI Action:
var gdw = new GlideDialogWindow('incident_display_list');
gdw.setTitle('Parent Incident');
gdw.setPreference('table', 'incident_list');
gdw.setPreference('title', 'A New Title');
var query = 'active=true^sys_idIN'+param;
sid = param.split(",");
gdw.setPreference('sysparm_query', query);
gdw.render();
Wiki&Community have some good basics on this as well:
