Hi Team,
I have below OnSubmit Catalog Client Script which checks attachment asynchronously, I have to use asynchronous server call only, but it will not wait for the response from the server and will let the system submit the form. It should check and alert the user for those mandatory attachments before the form submission.
Could you please suggest me the best approach for it, below is my code.
function onSubmit() {
//Type appropriate comment here, and begin script below
var catId = g_form.getParameter("sysparm_item_guid");
var ajaxAttachGlideAJAX = new GlideAjax('GetAttachment'); //calling S.I by GlideAjax
ajaxAttachGlideAJAX.addParam('sysparm_name', 'getAttachment');
ajaxAttachGlideAJAX.addParam('sysparm_catID', catId);
ajaxAttachGlideAJAX.getXML(callback);
function callback(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
if (answer == 'false') {
alert(" Please add a file ");
return false; //abort form to submit
} else {
return true;
}
}
}
Please help me with another possible way or what correction can be done to existing code to achieve the same.
