Show second UI page from first one

Vaibhav39 · ‎02-09-2021

Hello,

My requirement is to show second UI page from first and that too in same window / frame.

There are two UI pages already created (say page1 & page2).

On click of UI action, if there are records in related list, show page1 & then page2 else show only page2. See below code.

Page1 HTML:

<g:ui_form>
	<input type="hidden" id="cancelled" name="cancelled" value="false"/>
	<input type="hidden" name="task_id" id="task_id" value="${RP.getWindowProperties().get('sysId')}"/>
	<g:evaluate var="jvar_URL" object="true">
        <!-- Code will check records and put all sys_ids in an array and return an URL -->
		url;
	</g:evaluate>
	<table>
		<tr id="dialog_buttons">
			<td colspan="2" align="left">
				<g:dialog_buttons_ok_cancel ok="return onSubmit();" cancel="return onCancel();" />
			</td>
		</tr>
		<br/><br/>
	</table>
	<table>
		<tr>
			<td><iframe src="${jvar_URL}" scrolling="yes" width="900" height="400"/></td>
		</tr>
	</table>
</g:ui_form>

If I wrote the <iframe> first & then dialog_buttons_ok_cancel then those buttons are not displaying.

Page1 Client script:

function onSubmit() {
	var taskId = gel('task_id').value;
	alert("task id="+taskId);
	GlideDialogWindow.get().destroy();
}

function onCancel() {
    var cancel = gel('cancelled');
    cancel.value = "true";
    GlideDialogWindow.get().destroy();
    return false;
}

Page1 Processing script:

if ('false' == cancelled) {
	response.sendRedirect("ui_page.do?sys_id=<SYS_ID_OF_PAGE2>");
}

The issue I'm facing is for second page. Page2 is not getting displayed in same UI page window/frame.
Also, if I click on "Cancel" button then it is redirecting to new record instead of same record.

Please help me to solve this issue.

Thanks in advance.

So here's a skeleton of how this could be done:

A client UI Action where field Onclick = u_onClick():

var u_onNextDlg;
var u_onCloseDlg;

function u_onClick () {
	var IS_READ_WRITE = false,
		dialog_1 = new GlideModal('u_ui_page_1', IS_READ_WRITE, 1024);

	dialog_1.setTitle('Title 1');

	dialog_1.render();

	u_onNextDlg = function (dialog_1) {
		return function (param) {
			dialog_1.destroy();

			var dialog_2 = new GlideModal('u_ui_page_2', IS_READ_WRITE, 1024);

			dialog_2.setTitle('Title 1');
			dialog_2.setPreference('sysparm_id', param);

			dialog_2.render();

			u_onCloseDlg = function (dialog_2) {
				return function () {
					dialog_2.destroy();
				};
			}(dialog_2);
		};
	}(dialog_1);
}

Make sure the UI Action is NOT marked as "Isolate script".

Next, the 1st UI Page:

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<g:ui_form>

		<article class="modal-body">
			<div class="form-horizontal">
				<span class="section">
					<div class="section-content" glide="true">
						<p>Content 1...</p>
					</div>
				</span>
			</div>
		</article>

		<footer class="modal-footer">
			<g:dialog_buttons_ok_cancel cancel_type="button" ok_id="u_ui_page_1_ok" ok="u_onNextDlg('an id')" ok_type="button"/>
		</footer>
	</g:ui_form>
</j:jelly>

Finally the 2nd UI Page:

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<g:ui_form>

		<article class="modal-body">
			<div class="form-horizontal">
				<span class="section">
					<div class="section-content" glide="true">
						<p>sysparm_id: $[ sysparm_id; ]</p>
						<p>Content 2...</p>
					</div>
				</span>
			</div>
		</article>

		<footer class="modal-footer">
			<g:dialog_buttons_ok_cancel cancel_type="button" ok_id="u_ui_page_2_ok" ok="u_onCloseDlg()" ok_type="button"/>
		</footer>
	</g:ui_form>
</j:jelly>

Of course this is just for demonstration, a lot of things is hard-coded, but when one clicks the UI Action, the 1st UI Page is shown, when that dialog is dismissed pressing the OK button, the 1st UI Page is unloaded and the 2nd UI Page is shown, receiving parameters that might have been passed to it by the 1st UI Page's OK routine. Hard-coded, of course.

Hope this helps.

Just an idea: I don't know why

GlideDialogWindow.get

is used or suggested, as far as I can tell, that is not a thing, method get does not exist on object GlideDialogWindow.

Nothing. Blank.

Hi,

are you getting the task sys_id in the 1st UI page itself.

If not then it won't pass to 2nd UI page

what came for this for 1st UI page

var taskId = gel('task_id').value;
	alert("task id="+taskId);

alert("task id="+taskId);

Above line is working fine. I'm getting the sys_id.

Not sure why it is not sending to page2.

And one more thing, that page2 is not getting loaded in frame like ui page do.

Hi,

So is the 2nd UI page getting called?

Do you wish to see the alert when Cancel is clicked or when OK is clicked
