I want to render some javascript snippet with sapui5. I am trying to use Text control but when I use that I cannt format javascript text to show up properly.Is there a way to do that?
You can use the HTML core control to embed html/javascript: https://sapui5.hana.ondemand.com/sdk/#docs/api/symbols/sap.ui.core.HTML.html
Or create a custom control
All other SAPUI5 controls are protected against XSS and forgery attacks so they won't accept any javascript code.
I also suggest that you use sap.ui.core.HTML to embed HTML in your sapui5 view. However to get your code formatted correctly (for example it shall be indented correctly) you can use the markdown-js library. See this example:
index.html:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
<title>Render javascript source code in sapui5</title>
<script id="sap-ui-bootstrap"
src="https://sapui5.hana.ondemand.com/resources/sap-ui-core.js"
data-sap-ui-theme="sap_bluecrystal"
data-sap-ui-libs="sap.ui.commons"></script>
<script src="markdown.js"></script>
<script>
$.get("markdown.md", function(data) {
var mdView = new sap.ui.core.HTML({
content: markdown.toHTML(data)
});
mdView.placeAt("uiArea");
}, "html");
</script>
</head>
<body class="sapUiBody">
<div id="uiArea"></div>
</body>
</html>
markdown.md:
# Markdown
To produce a code block in Markdown, simply indent every line of the block by at least 4 spaces or 1 tab.
for (i=0; i < 10; i++) {
if (true) {
console.log("Hello World!");
}
}
If you want to test this example in you Chrome browser, do the following:
Download markdown-browser-*.tgz from markdown-js and place the contained markdown.js together with the above index.html and markdown.md in some folder.
Start Chrome with parameter --allow-file-access-from-files and drop the index.html on the Chrome browser window.

When one adds an event handler to a tinymce-editor web component, the target of the received event appears to not be the tinymce-editor element, but another component
below the shadow-root of the tinymce-editor element.
Is there any simple way around this because its quite difficult to determine which tinymce-editor element the event was from if you have more than one for example?
(Is this a common approach for, or limitation of, web components or something - seems a bit odd??)
Sample Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<script>
function changeHandler(evt) {
console.log(evt.target.id); //gives something like mce_<n>
}
</script>
<tinymce-editor id='e1' api-key="<api-key>" on-Change="changeHandler"></tinymce-editor>
<tinymce-editor id='e2' api-key="<api-key>" on-Change="changeHandler"></tinymce-editor>
<script src="https://cdn.jsdelivr.net/npm/#tinymce/tinymce-webcomponent#2/dist/tinymce-webcomponent.min.js"/>
</body>
</html>
In some html editors when you create a new html file, some default codes as below created automatically:
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8"/>
</head>
<body>
</body>
</html>
how can I enable this feature in VSCode editor?
Thanks.
Press shift and 1 (!) It will show two options select the first one or type html:5 and enter the option it will give you default boilerplate for html
Just give the ! sign and then press Tab.
is it possible to add an event to SAPUI5 sap.ui.commons.Panel's minimize and maximize? What i need is to add a different style when the Panel's collapse- or expand-Button is clicked.
If the user clicks on the minus-Symbol i have to add a styleclass like pnl.addStyleClass("XYZ"); when the user clicks on "maximize" a different styleclass should be added to the panel pnl.addStyleClass("ZYFDEFD");
if i overwrite the .setCollapse- or .setExpanded-function the panel doesn't collapse or expand anymore, so something else has to be found.
A couple of possible options...
1) You could make use the standard style class (sapUiPanelColl) which is added to the control depending on the expanded state - see example below...
var oPanel = new sap.ui.commons.Panel({});
oPanel.addStyleClass("myPanel");
oPanel.placeAt("content");
.myPanel { background-color: green; }
.myPanel.sapUiPanelColl { background-color: red; }
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>sap.ui.commons.Panel style class example</title>
</head>
<body id="content">
<script src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js" id="sap-ui-bootstrap" data-sap-ui-theme="sap_bluecrystal" data-sap-ui-libs="sap.m,sap.ui.commons"></script>
</body>
</html>
2) Alternatively, if it's not essential to use the Panel from the commons library you could switch to sap.m.Panel (as the sap.ui.commons.Panel is depreciated since version 1.38) and then make use of the expand event
I want to use jquery live() to automatically select the text in a text box but it doesn't seem to work in internet explorer 8. Here's the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js"></script>
<script type="text/javascript">
$(function(){
$('input.textInput')
.live('focus',
function(e){
$(this).select();
// alert(1) // if i uncomment this it works
});
});
</script>
</head>
<body>
<input type="text" class="textInput" value="0,00" />
</body>
</html>
If, however, i uncomment the alert(1) statement it does work. Any ideas what the problem is here?
This is strange, it also works if you don't use the live event:
http://jsfiddle.net/JKVXU/1/
Try
$('input.textInput').live("focus",function(e){
$(this).focus(function () {
$(this).select();
});
});
http://jsfiddle.net/JKVXU/23/
Have you tried using val() to get the text box vlaue instead?
I think the browser doesn't like the integer value on the alert.
try this: alert('1');
I'm having strange issues with text on a canvas when using an iPhone or iPad.
Either the text gets drawn properly (rarely), or it gets drawn upside down, or it doens't get drawn at all.
When the text does manage to get drawn, it is wiped when the iPhone/Pad is rotated.
I have the following code. It seems that I can only get the text to stay on the page at all if I use a setTimeout. It seems to be drawn over if I call fillText as soon as the document is loaded.
Anyone else experiencing this sort of problem?
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<script src="http://code.jquery.com/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
//draw_b();
setTimeout('draw_b()', 500); ;
});
function draw_b() {
var b_canvas = document.getElementById("cv");
var context = b_canvas.getContext("2d");
context.fillText("Belated hello world", 50, 50);
}
</script>
</head>
<body>
<canvas id="cv" width="300" height="225"></canvas>
</body>
</html>
I have the same problem ,
the earlier version(3.2) doesn't support HTML5 Canvas filltext,
You can use alternative API such stroketext to fix this issue: http://www.netzgesta.de/dev/text/#canvas_api
