Escaping jelly

GregLusk · ‎03-07-2017

I am trying to use the <g:no_escape> tag to stop escaping a variable that has HTML. It is not working and I can not figure out why. UI Page code is below. Thanks for any help.

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

a {

color: blue;

text-decoration: underline;

}

img {

visibility: visible;

display: inline;

}

table {

white-space: normal;

width: 80%;

border-style: solid;

border-width: 2px;

border-color: #000000;

}

tr.gray{

background-color: #C0C0C0;

}

td.field {

width: 25%;

text-align: right;

padding-right: 10px;

font-weight: bold;

}

td.info {

text-align: left;

padding-left: 5px;

}

</style>

<head>

<br/>

<g2:evaluate var="jvar_link" jelly="true">

var id = RP.getWindowProperties().get('id');

//var id = 'eb8439590f19f200c1a16ab8b1050eac';

var number = '';

var grOut = new GlideRecord('incident');

grOut.get(id);

grOut.next();

var link = grOut.getLink(true);

link;

</g2:evaluate>

<g2:evaluate var="jvar_updates" object="true">

var upd = grOut.work_notes.getJournalEntry(-1); //gets all journal entries as a string delimited by '\n\n'

upd = upd.replace(/\[code\]/g, "");

upd = upd.replace(/\[\/code\]/g, "");

var na = upd.split('\n'); //convert the updates to an array of strings

na; //return the array to the jvar_updates variable for use in the table below

</g2:evaluate>

</head>

<body>

<j2:whitespace trim="false">

<table>

<td colspan="2" align="center" style="font-size: 18;">Work Notes</td>

</tr>

<tr>

<j2:if test="$[jvar_updates.length gt 0]">

<j2:forEach var="jvar_upd" items="$[jvar_updates]">

<g:no_escape>$[jvar_upd]</g:no_escape>

</j2:forEach>

</j2:if>

</script>

</td>

</tr>

</table>

</center>

</j2:whitespace>

</body>

</j:jelly>

I figured it out. There is nothing wrong with the last code I posted. UI Pages do not render the same if they are invoked using GlideDialogWindow. When you use GlideDialogWindow escaped HTML is treated as XML.

Hello Gregory,

Please refer

Thanks Pradeep, I have gone over that document and every single document relating to escaping jelly I could find and I still can not figure out why my code does not work.

I simplified my UI page and now it appears that it is not escaping the HTML, but I get errors about end tags missing. It's as if it is being interpreted as XML instead of HTML. Here is my new code:

<?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:evaluate>

var id = RP.getWindowProperties().get('id');

//var id = 'eb8439590f19f200c1a16ab8b1050eac';

var grOut = new GlideRecord('incident');

grOut.get(id);

grOut.next();

var docType = '<!DOCTYPE HTML>';

var upd = grOut.work_notes.getJournalEntry(-1); //gets all journal entries as a string delimited by '\n\n'

//upd = upd.replace(/\[code\]/g, "");

//upd = upd.replace(/\[\/code\]/g, "");

//upd;

</g:evaluate>

<g:no_escape>${HTML:upd}</g:no_escape>

</j:jelly>
