In the below example, infoScroller is a UIWebView and println(HTMLDescription) prints a lovely string of HTML. However, the attempt to loadHTMLString gets the runtime error: fatal error: Can't unwrap Optional.None
if let HTMLDescription = self.myData?.content? {
println(HTMLDescription)
infoScroller.loadHTMLString(HTMLDescription, baseURL: nil)
}
I've tried every combination of ! and ? in both the assignment and use of the string but I get this same error every time, though the variable never fails to print out perfectly to the console.
There is another value that I set using the same method and it works fine. Both are strings, but the other one is more simple in that HTMLDescription is multiline and the working one is not.
Edit: The discussion in the comments prompted me to check the infoScroller and it's description as printed in the console is: (#sil_weak UIWebView!) infoScroller =
I'm thinking that's the issue, but I'm not sure what it means or how to fix it.
Edit 2: This has to be the issue. println(infoScroller.description) yields the exact same error.
Got it! This question put me on the path. I was trying to load the content before the view was fully loaded. Moved loadHTMLString() into viewDidLoad(). Stupid simple.

Please don't ask me not to use eval, this isn't going to be public anyways.
I've made a chatting website, and I have implemented a "!eval" command (admin only), whatever is after it is run. I can use "!eval '2'+'2'" (Strings added), but not "!eval 2+2." The error returned is .
I've console.logged the input to the eval, and it returned exactly what I wanted: "1+1." I've looked around for this, but it seems like no one else had this problem before. A solution (more like a debugging one) is that I tried "eval('1+1')" and returned the same error. Any thoughts? Thanks in advance.
(I forgot to add what I was expecting)
I was expecting this.
VLAZ pointed out in the comments that it must be another piece of code, which he is correct. I was encrypting the messages so it can be sent securely to the client, and it only takes a string. I added
if (typeof(results) != 'string'){
results = String(results)
}
and it seemed to work, Thanks!
L20N is setup in my ReactJS project and I am calling getSync on the context after its ready event has fired (so things should be good to go). However, rather than my expected string including other Entity values and variable expansion, I get the raw Entity string.
The string I get looks like this:
{{$user.name}} - {{appName}}
But of course, I'm expecting something like this:
Ben Taylor - My Cool App
I have tried to recreate the problem in this plunker. Unfortunately, it works fine! When you run it, the alert box shows the expected L20N expanded string.
What could cause the Entity value to be returned raw? I have a valid context and there are no errors in inspector, so it appears all is configured fine. I'm wondering if there is some interaction with something else I'm doing that is breaking L20N. Any ideas appreciated!
I am unable to include the app I'm working on, but needless to say it has more moving parts. It is a React app based on this template.
If there is some sort of error in your .l20n file (the extension formerly known as .lol) then the getSync call will return the raw string value. In my case the error was to quote the keys in an L20n dictionary.
If you have context data like { user: { type: "Awesome" } } then the following does not work and calling getSync for useTheShout will return the unprocessed string value (including the text {{shout}}):
<shout[$user.type] {
"Awesome": "HEY AWESOME USER!",
"Loser": "i can't be bothered to shout at you loser..."
}>
<useTheShout "I'm gonna shout the following: {{shout}}">
Removing the quote marks from the dictionary key names will make this work, as follows:
<shout[$user.type] {
Awesome: "HEY AWESOME USER!",
Loser: "i can't be bothered to shout at you loser..."
}>
<useTheShout "I'm gonna shout the following: {{shout}}">
Update: You can avoid the pain by logging using the error and warning event emitters.
This is probably a stupid one but I have tried all the things I can think of. I am currently getting the below error on my client side script when I try and execute it.
Error: ReferenceError acvt_serialNumber_saveRecord is not defined
On the Script record in Netsuite I have set the saveRecord function as follows:
acvt_serialNumber_saveRecord
The code in the file is:
function acvt_serialNumber_saveRecord(){
/**do stuff */
}
I have reuploaded to code to make sure the right version was in NetSuite. I have added one character to both the script fn name and the fn name on the Script record (as a shot in the dark). I have seen in the Javascript console at runtime that the correct code is in there and I can see the exact function name (I did a ctrl+f for the "undefined" function in the code in the console to make sure spelling was all the same).
NOTHING has worked. I had this code working earlier, but the changes I made were not to this function at all.
Any help is appreciated
Another thing to check is the code that you recently changed. In particular, check for a hanging comma. IE:
var someObj = {
someProp:'somevalue',
};
The comma at the end of 'somevalue' will cause the script to fail, throwing 'undefined' errors.
Have you tried deleting the Script record in NetSuite and re-creating it?
Do you have any library included for that Client Script in netsuite ?
Provide a screen shot of your Netsuite script page
I encounter similar problem like this before, but it was because i called a function which is inside a library file
Thanks
I just started trying out Derbyjs, and I already ran into a problem. I can't find any support for this error, and most likely is some dumb mistake i'm making.
I'm trying to render a view, following the example from the www.derbyjs.com documentation.
My app is as simple as this:
var app = require('derby').createApp(module);
app.get('/', function (page, model) {
page.render('home');
});
My views are composed by two files.
"index.html"
<import: src="home">
<Body:>
Default page content
"home.html"
<Body:>
Welcome to the home page
I get the following error whenever the page is rendered:
TEMPLATE ERROR
Error: Template import of 'home'... ...can't contain content
As you can see, it is a very simple example. What am I missing?
I get that error even if I have the "home.html" file empty.
Well, I got the answer from one of the developers.
It seems like there was a subtle bug in the Template Parser that probably has already been fixed.
Having a whitespace or linebreak in front of
<import: src="home">
was causing the parser to raise the error. Writing
<import: src="home"><Body:>
solved the issue.
Not sure why, but I'm getting an unexpected identifier error when trying to append an element to the document in a response function. I've found that doing anything with the document seems to give me this error. Here's a sample code:
chrome.extension.sendRequest({send:data},function(response) {
document.body.innerHTML='test'
})
It looks to me like it should work, but evidently it does now. This piece of code is located in the contentscript, and messing with the document outside of this function seems to work just fine, but I always get "unexpected identifier" when trying this. Unfortunately I cannot do it outside of the function because the response determines whether or not an element is added to the body.
The code you shared should work. Try restarting your browser to see if that fixes it.
