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.

Yes, Page2 is getting displayed but not like UI pages used to get displayed. Means not in frame.

I think the code written in processing script is running.

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

Above code is in the processing script of first ui page.

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

This one.

Hi,

Why are you calling the 2nd UI page from processing script if you are already calling it from Client script

Actually, I just tried with commenting the code in processing script and kept the client script code.

But the second page is not getting called.

function onSubmit() {
	var taskId = gel('task_id').value;
	alert("task id="+taskId);
	//GlideDialogWindow.get().destroy();
	
	var closureDialog = new GlideDialogWindow("for_testing");
	closureDialog.setTitle("Closure Fields"); //Set the dialog title
	closureDialog.setSize(600, 600);
	closureDialog.setPreference("secondSysId", taskId);
	closureDialog.render(); //Open the dialog
	GlideDialogWindow.get().destroy();
}

This is the code I'm trying but not working. Page2 is not getting displayed.

And I commented the processing script code.
