I'm using WebView2 to display data in my app. If I send a string literal it works fine. But if I send a value in a variable I get nothing.
This works:
wb.ExecuteScriptAsync("document.body.innerHTML=" & ChrW(39) & "HELLO" & ChrW(39))
This doesn't ("lStr" is my string variable):
wb.ExecuteScriptAsync("document.body.innerHTML=" & ChrW(39) & lStr & ChrW(39))
I assume I'm doing something wrong here. Any advice is appreciated.

That's going to depend on the content of your variable, which we can't see.
For example, if the variable contains a single quote or any newline characters, your script will end up with an "unterminated string literal" error.

Could possibly contain quotes but no newline chars. I was trying to give my old spell checker a facelift. I wanted to use the WebView2 for the error text ("Not In Dictionary"). It's one line from the text editor with the error highlighted. So I'd need to send it the error start/end positions plus tell it to scroll to that position. All easily done if I could figure out how to send it a value in a variable.

As I said, you'll need to ensure the value is properly encoded.
Assuming you're running .NET Framework 4.7.2 or later, .NET Core, or .NET 5+, then you can use the System.Text.Json package[^] to encode the string:
wb.ExecuteScriptAsync("document.body.innerHTML=" & System.Text.Json.JsonSerializer.Serialize(lStr)) For older frameworks, use the Json.NET[^] package.

Hi,
New here. Anyway I'm working on a project and I'm placing some text over some images. All is good with that.
However I only want to rotate the text 35 degrees but I can't figure how to do that in Javascript.
Here is how I'm displaying the text -
const ctxt = canvas.getContext('2d');
ctxt.fillStyle = 'red';
ctxt.font = '40px Brush Script MT';
ctxt.fillText('TEST',200,178);
Thanks.

The canvas uses a transformation matrix and it has a few functions for manipulating it.
Here is a 35-degree rotation:
const ctxt = canvas.getContext('2d');
ctxt.fillStyle = 'red';
ctxt.font = '40px Brush Script MT';
const tm = ctxt.measureText('TEST');
ctxt.translate(200 + tm.width / 2, 178);
ctxt.rotate(35 * 3.14159 / 180);
ctxt.translate(-(200 + tm.width / 2), -178);
ctxt.fillText('TEST',200,178);
ctxt.resetTransform();

Awesome! Just what I needed. Thanks!

An unformatted dump of your exception message, with no details of the code, posted in the wrong forum?
Sure, let us get right on helping you to fix that.

That looks like something you should start your investigation with.

What are the differences between Heap and Stack Memory in Java?
modified 1-Jun-22 13:03pm.

Yes, but you need to provide the details. You also need to post it in the Java forum; this one is for Javscript which is not the same thing. But do not expect anyone here to do all the work for you, even if you do offer ridiculous amounts of money.

I have a SharePoint List (list_dls) which has all the Email addresses. The list has a single column with Field name "Title". I need to validate that the Item in the "LookupField" is contained in the 'list_dls'. The list has over 5000 emails, hence I will need to do a CAML query. The script does not seem to find the item. Any ideas to get it to work would be really appreciated.
Here is the code.
<pre><input type='button' value='get Lists' onclick="PopulateLookupField();"/>
<p id="demo"></p>
<script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
var LookupField = 'lnam@xyz.com';
function PopulateLookupField()
{
var clientContext = new SP.ClientContext.get_current();
var LookupList = clientContext.get_web().get_lists().getByTitle('list_dls');
var camlQuery_list = new SP.CamlQuery();
camlQuery_list.ViewXml = @"<View Scope='RecursiveAll'><ViewFields><FieldRef Name='ID'/><FieldRef Name='Title'/></ViewFields><RowLimit Paged='TRUE'>5000</RowLimit></View>";
LookupList<ListItem> allListItems = new LookupList<ListItem>();
do
{
var listItemCollection = LookupList.GetItems(camlQuery_list);
clientContext.Load(listItemCollection);
clientContext.ExecuteQuery();
allListItems.AddRange(listItemCollection);
var ItemFound = listItemCollection.Where(item => item.FieldValues["Title"].ToString().Contains(LookupField);
if(ItemFound !== null){break;}
camlQuery_list.ListItemCollectionPosition = listItemCollection.ListItemCollectionPosition;
} while (camlQuery_list.ListItemCollectionPosition != null);
clientContext.load(ItemFound);
alert("ItemFound = " + ItemFound);
}
</script>

Hello everyone,
I have a problem that I'm having trouble solving, I have the following errors on my screen:
1. Error in src\App.js line 2:7: parsing error: identifier 'react' has already been declared.(2:7)
Webpack 5.72.0 compiled with 2 errors 2.in 8076 I show you an example of the code
1.Import React from "react"
2.Import react, {component} from "react";
Const App = () => {
Return(
< BrowserRouter>
<route path="/" element="{Home/">}/>
<route path = '/About'element = {About/>}
)
}
Thanks for your help

|

I think it's because you are already importing react on line 1. You don't need the "import react" on line 2.

Based on this GitHub issue[^], it looks like addImage can't use the path of an image on the server to generate a file on the client.
The suggested workaround is to load the image as a buffer. The code in the issue uses axios, but you could use the fetch API instead[^]:
const imageSrc = '/assets/images/graph.jpeg';
const response = await fetch(imageSrc);
const buffer = await response.arrayBuffer();
const imageId1 = workbook.addImage({
buffer: imageBuffer.data,
extension: 'jpg'
});

I am learning Javascript right now and am looking to start as soon as possible, but I don't know where to begin.
In my mind I would like the user experience to be as simple as possible; focused on the centre of the screen, on a single drop down menu, of which when a choice is selected that menu visually slides out of the way (so the user doesn't feel disoriented), as a new one slides in, and so forth, until the selections are exhausted.
What should I look into to achieve this please ?

|
|
|
|

Thanks, but I'm already working through that (about half way through). What a mess JavaScript has become, how on Earth a let can be a var God only knows, especially coming from a type-safe language like Swift ?!
I found the following code, which was pretty similar to what I wanted : https://codepen.io/balapa/pen/zvObzO[^]
I am just figuring out how the code works now, to see how to load up new menu options..

After the file is played, you need to load a new file and start playback.
According to my plan, I did this:
the file "au.js"
function replay()
{
var aud = document.getElementById("audio_label");
aud.src = "cap.wav?cb=" + new Date().getTime();
aud.load();
aud.play();
}
function hproc(e)
{
replay();
}
var x = document.getElementById("audio_label");
x.addEventListener('ended',hproc,false);
the "index.html"
<pre><script src="au.js"></script>
<body>
<audio id="audio_label" autoplay controls src="cap.wav"
type="audio/wav"></audio>
...plays only once...
