How to call a script include function with a parameter in a catalog client script

[pavani19]

the script include is:

var RL_WkeyLinkDetails = Class.create();
RL_WkeyLinkDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {
callRLapi : function(wkey){
var r = new sn_ws.RESTMessageV2('RL_rldbApi', 'Get_WkeyLinkDetails');
midserver = gs.getProperty('mid.server.rba_default');
r.setMIDServer(midserver);
r.setStringParameter('code',wkey);
var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

var res= JSON.parse(responseBody);
var res1= JSON.stringify(res);
if(res.length>0){
alert("Do you want to update the site map link of :"+ wkey +":"+res[0].shortDesc);
} else{
alert(" please enter a valid wkey");
}

},

type: 'RL_WkeyLinkDetails'
});

i want to call this script include from catalog client script and pass the wkey parameter value from input value of catalog request field value.

catalog client script is:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

//Type appropriate comment here, and begin script below
var wkey = g_form.getValue('ux_wkey') ;//geeting variable value

var ga = new GlideAjax('RL_WkeyLinkDetails'); // SI Name
ga.addParam( 'sysparm_name', 'callRLapi'); // Function Name


}

i am not getting an idea how to pass wkey parameter for callRLapi function.

please help..

Hi,

Please reference this cheat sheet to accomplish what you need: https://community.servicenow.com/community?id=community_article&sys_id=9f7ce2e1dbd0dbc01dcaf3231f961...

You also need to make your script include "client callable" as well.

Please mark reply as Helpful/Correct, if applicable. Thanks!

Hi,

I'm glad you found an answer your question. The overarching issue is that you aren't aware of how to use GlideAjax...please still reference the link I provided. It's nice for the other user to literally give you all the code to use, but you don't learn anything.

Take care!

Hi Pavani,

Your script include and catalog client script looks incorrect; please correct it as below

Script Include: Corrections

1) you need to call API and only send the response body from the function

2) you need to get the wkey using this.getParameter() terminology

var RL_WkeyLinkDetails = Class.create();
RL_WkeyLinkDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

callRLapi : function(){

// this is how you get the value passed from client script

var wkey = this.getParameter('sysparm_wkey');

var r = new sn_ws.RESTMessageV2('RL_rldbApi', 'Get_WkeyLinkDetails');
midserver = gs.getProperty('mid.server.rba_default');
r.setMIDServer(midserver);
r.setStringParameter('code',wkey);
var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

return responseBody;

},

type: 'RL_WkeyLinkDetails'
});

Catalog Client Script Corrections:

1) send sysparm_wkey with the form value

2) parse the json response body returned from the script include function

catalog client script is:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

//Type appropriate comment here, and begin script below
var wkey = g_form.getValue('ux_wkey') ;//geeting variable value


var ga = new GlideAjax('RL_WkeyLinkDetails'); // SI Name
ga.addParam('sysparm_name', 'callRLapi'); // Function Name
ga.addParam('sysparm_wkey', wkey); // send the value to script include function

ga.getXML(getValue);

}

function getValue(response){

var answer = response.responseXML.documentElement.getAttribute("answer");

var parsedData = JSON.parse(answer);

// parse the json and set the value wherever required

// parse for url, short description, app ID

// use g_form.setValue() to set the values

}

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks
Ankur

Thanks Ankur for Your response.

i am getting error in script message while executing the g_form.setValue statement.

this is script include:

var RL_WkeyLinkDetails = Class.create();
RL_WkeyLinkDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {
//callRLapi : function(wkey){

callRLapi : function(){
var wkey = this.getParameter('sysparm_wkey');
var lang=this.getParameter('sysparm_lang');
var r = new sn_ws.RESTMessageV2('RL_rldbApi', 'RL_WKeylinkdetails');
midserver = gs.getProperty('mid.server.rba_default');
r.setMIDServer(midserver);
r.setStringParameterNoEscape('userKey', wkey);
r.setStringParameterNoEscape('languagueCode', lang);

var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

return responseBody;

},

type: 'RL_WkeyLinkDetails'
});

catalog client script
