Ho do you use GlideAjax in Catalog Clint Script?

[aryanjain27]

Hey,

I've recently learned about GlideAjax and was using it in the catalog clint script but couldn't make it to work. I have a table 'x_accounts' that has columns u_account_id and u_account_alias. I have a reference variable in the catalog item that is referencing this table via account_alias and depending upon what account is selected I want to account_id to be shown on the catalog item. So I have another read only variable for account_id whose value I am setting in catalog clint script. I used glideAjax to get the account_id from the table but its not working. Is it implemented correctly?

Catalog Clint Script:

onChange is applied on the account_alias variable on the catalog item.

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

    // Perform a GlideAjax call to fetch the id based on the selected name
    var ga = new GlideAjax('D_Ajax');
	ga.addParam('sysparm_name','getAccountId');
    ga.addParam('sysparm_accountSysId', newValue);
	ga.getXMLAnswer(function(answer){
		var response = JSON.parse(answer);
		g_form.setValue('account_id', response.accountId);
	});
}

Script-Includes:

var D_Ajax = Class.create();
D_Ajax.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    getAccountId: function() {
        var account_sys_id = this.getParameter("sysparm_accountSysId");
        var gr = new GlideRecord("x_accounts");
        gr.get(account_sys_id)
        accountId = gr.u_account_id;

	    var response = {};
	    response.accountId = 'Test'; // Debugging
        return JSON.stringify(response);
    },
	type: 'D_Ajax'
});

 To debug, I set the response static to verify if the issue is with glide record. But even after that I do not see the text 'Test' on the account_id variable in the catalog item.

Any help would be appreciated.

Thanks!

Hi there,

Have you considered a more no code solution for this?

Wow, This is very interesting! Learning something new everyday.

Although I am all for trying to get things to work, especially when you are trying things you just learned, why not use the 'auto populate' tab on the variable? Client scripts are less performant than using this OOB functionality.
