How to retrieve URL parameters in a scoped app in an onLoad client script

[Sheryl Lyke2]

Within a scoped app, I have a UI action on a custom table form with the following code:

 var nameCI = current.name;
 var comp = current.invoice_parent.company;
 var url = 'cmdb_ci.do?sys_id=-1&sysparm_view=contract_management&sysparm_view_forced=true?sysparm_CIname=' + nameCI + '?sysparm_Comp=' + comp;

 action.setRedirectURL(url);
 action.setReturnURL(current);

This works. Then I have an onLoad client script where I want to take the parameter values being sent in the url to populate fields. I've seen similar code working so I don't know if it's because I'm in a scoped app but it's not working. It doesn't populate. Even the addinfoMessage or setMandatory pieces don't work. I had an addInfoMessage at the start and that did work so I know the script is triggering. Any idea why I can't use the getParameterValue function here? Or does someone have another way to send values from a UI action to a client script in a scoped app? I've tried setting isolate script to true and this also does not have any effect. Thanks!

function onLoad() {
	g_form.setMandatory('model_id', true);
        var nm = getParameterValue('sysparm_CIname');
   
    if (nm) {
        g_form.setValue('name', nm);
    } else {
        g_form.addInfoMessage('no name');
    }
    var comp = getParameterValue('sysparm_Comp');
    if (comp) {
        g_form.setValue('company', comp);
    }
}

function getParameterValue(name) {
    var url = document.URL.parseQuery();
    if (url[name]) {
        return decodeURI(url[name]);
    } else {
        return;
    }
}

Can you try commenting out this line in your UI action

//action.setReturnURL(current);

See if the url alert goes to cmdb_ci

Also can you check the url formation. it has some extra '?'

It should be

var url = 'cmdb_ci.do?sys_id=-1&sysparm_view=contract_management&sysparm_view_forced=true&sysparm_CIname=' + nameCI + '&sysparm_Comp=' + comp;

Thank you! Finally got it working. I did have an errant ? in there. Final code for others:

UI Action code

var nameCI = current.name;
var comp = current.invoice_parent.company;
var url = 'cmdb_ci.do?sys_id=-1&sysparm_view=contract_management&sysparm_view_forced=true&sysparm_CIname=' + nameCI + '&sysparm_Comp=' + comp;

action.setRedirectURL(url);
action.setReturnURL(current);

OnLoad client script

function onLoad() {
    g_form.setMandatory('model_id', true);
	g_form.setMandatory('location', true);
    var glideURL = new GlideURL();
    glideURL.setFromCurrent();
    var comp = glideURL.getParam("sysparm_Comp");
	if (comp) {
        g_form.setValue('company', comp);
    }
    var CI = glideURL.getParam("sysparm_CIname");
	if (CI) {
        g_form.setValue('name', CI);
    }

The setMandatory is still not working but it looks like that's due to it being on a global table
