Asynchronous GlideAjax in onSubmit not working

[wayneryeo]

Hi,

I have a single line variable in sp which i need to validate whether this value exists in the table record. if it exists, it will prevent the form from submmiting and shows the error message below the variable.

I am using the following in catalog client script with script include using async glideajax. can anyone help to advise as i cant seem to get the answer to stop my form submission? Thank you!

g_form.hideFieldMsg('name');

var validate = false;

if(g_form.getValue('name') != '')

{

checkName();

}

if(validate == false)

{

g_form.submitted = false;

return false;

}

else {return true;}

}  

function checkName(){

var ga = new GlideAjax('nameAjax');

ga.addParam('sysparm_name','checkname');

ga.addParam('sysparm_namelist',g_form.getValue('name'));

validate = ga.getXML(serverResponse);

}

function serverResponse(response){

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

if(answer == 'true')

{

g_form.showFieldMsg('name','name Exists','error');

validate = false;

return false;

}

else{

validate = true;

return true;}

Hi Surya,

I tried your code but not able to get answer from my script includes.

alert(ga.getAnswer());         returns null value.i did a gs.info and confirmed that i am returning true on my script includes.

Sorry. forgot to add that my script includes is client callable and was able to get answer from script includes using async ajax before i changed my code.

Can you provide your server side code?

Hi Paul,

my script include as below. client callable is ticked and acessible from all application scope.

var nameAjax = Class.create();

nameAjax.prototype = Object.extendsObject(AbstractAjaxProcessor, {

checkname:function(){

gs.info('here');                             // this was printed in log.

var name = this.getParameter('sysparm_namelist');

var returnValue = '';

var gr = new GlideRecord('u_name_record');

gr.get(name);

gr.query();

if(gr.getRowCount() == 0)

{

returnValue = 'false';

}

else

{

returnValue = 'true';

}

gs.info(returnValue); // this returns true which means there is such record.

return returnValue;

},

      type: 'nameAjax'

});

I think it might be best to go with a simple solution first.

GlideAjax may not be the best choice for this scenario (onSubmit), especially if you're new to scripting.

Also, if this is for a scoped app, GlideAjax is off the table completely for this scenario.
Refactor this before going into production.

g_form.hideFieldMsg('name');
var validate = false;

if(g_form.getValue('name') != ''){
         validate = checkName();
}

if(validate == false) {
g_form.submitted = false;
         return false;
} else {
         return true;
} 

function checkName() {
var gr = new GlideRecord('u_name_record');
return gr.get(g_form.getValue('name'));
}
