client script to refresh a list in a tab

georgechen — Sun, 07 Feb 2016 00:08:19 GMT

Hello folks,

How can i refresh a list in a tab in a form with client script on the form? For example, when a record is saved, the Task SLAs tab does not immediately get updated, and the users need to click the Task = Form for Processing link (see below) to refresh the list.

Thanks in advance.

You can achieve this by below piece of code in your client script. You need to execute this based upon some logic

setTimeout(function(){ GlideList2.get("your_table_name").refresh(); }, 2000);

Hi George,

The below blog should answer your question.

Thanks Pradeep, I refer to the form, and have the code as a new client script on form_load

function onLoad() {

try {

var elementLookup = $$('div.tabs2_list');

var listName = "Task SLA";

for (i = 0; i != elementLookup.length; i++) {

if (elementLookup[i].innerHTML.indexOf(listName) != -1) {

//alert ('element ' + elementLookup[i].innerHTML + ' found');

var listHTML = elementLookup[i].id.split('_');

alert ('listHTML=' + listHTML);

var listID = listHTML[2];

alert ('listID=' + listID);

//nowRefresh(listID);

}

catch (err) {

alert(err.message);

}

function nowRefresh(id) {

GlideList2.get(id).refresh('');

}

When form loads, it pops up with the warnings,

If you could help, it would be greatly appreciated.

Regards,

Thank you for this tip, I have referred to Pradeep's wiki, and use the code below

function onLoad() {

try {

var elementLookup = $$('div.tabs2_list');

var listName = "Task SLA";

for (i = 0; i != elementLookup.length; i++) {

if (elementLookup[i].innerHTML.indexOf(listName) != -1) {

var listHTML = elementLookup[i].id.split('_');

var listID = listHTML[2];

nowRefresh(listID);

}

catch (err) {

alert(err.message);

}

function nowRefresh(id) {

GlideList2.get(id).refresh('');

}

I don't understand why it pops 'undefined' on GlideList2.get(id).refresh('');, the tab does not have a refresh button, does this make a difference?

Any advice would be appreciated.

Hi George,

I tried and here is the final script you have to write.

Script :

function onLoad() {

     //Type appropriate comment here, and begin script below

     GlideList2.get(g_form.getTableName() + '.task_sla.task').setFilterAndRefresh('');

}

Thanks very much Pradeep, it works like a charm! the Task Sla tab list refreshes effectively when form get reloads (saved/updated)

Your assistance is much appreciated.

Best regards,
