I'm currently teaching myself the Dart language, and my first app doesn't seem to be working right. Here's the code that's causing trouble:
usrLoc = int.parse(query("#txtLoc").text);
When I try to run the app, it opens fine, but when I click the button that triggers this (and three other similar parses), the debugger stops and tells me "Source not found" for int._native_parse(), int._parse(), and int.parse().
Any help would be greatly appreciated.
The text property for the specified element #txtLoc returns an empty string.
The parse method requires that:
The source must be a non-empty sequence of base- radix digits, optionally prefixed with a minus or plus sign ('-' or '+').
You can specify an onError named argument in your call to parse, which takes a callback that handles the invalid input. E.g., if you want the parse call to return the value 42 for all invalid input, you can do this:
usrLoc = int.parse(query("#txtLoc").text, onError: (val) => 42);
If you really expect the element to have some text, you can store the result of query("#txtLoc").text into a separate variable and verify the value. It would also be interesting to check what the real element type is or which tag is marked with id #txtLoc.
If you want to get the content of an input element, you should use the value property instead of text:
query("#txtLoc").value

I'm trying to modify an existing lua script that cleans up subtitle data in Aegisub.
I want to add the ability to delete lines that contain the symbol "♪"
Here is the code I want to modify:
-- delete commented or empty lines
function noemptycom(subs,sel)
progress("Deleting commented/empty lines")
noecom_sel={}
for s=#sel,1,-1 do
line=subs[sel[s]]
if line.comment or line.text=="" then
for z,i in ipairs(noecom_sel) do noecom_sel[z]=i-1 end
subs.delete(sel[s])
else
table.insert(noecom_sel,sel[s])
end
end
return noecom_sel
end
I really have no idea what I'm doing here, but I know a little SQL and LUA apparently uses the IN keyword as well, so I tried modifying the IF line to this
if line.text in (♪) then
Needless to say, it didn't work. Is there a simple way to do this in LUA? I've seen some threads about the string.match() & string.find() functions, but I wouldn't know where to start trying to put that code together. What's the easiest way for someone with zero knowledge of Lua?
in is only used in the generic for loop. Your if line.text in (♪) then is no valid Lua syntax.
Something like
if line.comment or line.text == "" or line.text:find("\u{266A}") then
Should work.
In Lua every string have the string functions as methods attached.
So use gsub() on your string variable in loop like...
('Text with ♪ sign in text'):gsub('(♪)','note')
...thats replace the sign and output is...
Text with note sign in text
...instead of replacing it with 'note' an empty '' deletes it.
gsub() is returning 2 values.
First: The string with or without changes
Second: A number that tells how often the pattern matches
So second return value can be used for conditions or success.
( 0 stands for "pattern not found" )
So lets check above with...
local str,rc=('Text with strange ♪ sign in text'):gsub('(♪)','notation')
if rc~=0 then
print('Replaced ',rc,'times, changed to: ',str)
end
-- output
-- Replaced 1 times, changed to: Text with strange notation sign in text
And finally only detect, no change made...
local str,rc=('Text with strange ♪ sign in text'):gsub('(♪)','%1')
if rc~=0 then
print('Found ',rc,'times, Text is: ',str)
end
-- output is...
-- Found 1 times, Text is: Text with strange ♪ sign in text
The %1 holds what '(♪)' found.
So ♪ is replaced with ♪.
And only rc is used as a condition for further handling.
I'm trying to retrieve an event from the grapi api based on a binary extended property that I already have a value for. I have retrieved this value from the same api so I know that an event with this value exists. I also know that the property id is correct since I used this with .Expand() to get the value.
var value = "BAAAAIIA4AB0xbcQGoLgCAAAAAAwMvfBFvzUAQAAAAAAAAAAEAAAAEZ53uCfQ51AhtRf+FNQjOk=";
var cleanGlobalObjectIdPropertyId = "Binary {6ed8da90-450b-101b-98da-00aa003f1305} Id 0x23";
var events = await client.Users["myuser#example.com"].Events.Request()
.Filter($"singleValueExtendedProperties/Any(ep: ep/id eq '{cleanGlobalObjectIdPropertyId}' and ep/value eq '{value}')")
.GetAsync();
This is the error i get:
Microsoft.Graph.ServiceException : Code: ErrorInvalidUrlQueryFilter
Message: The filter expression for $filter does not match to a single extended property and a value restriction.
I have used the same filter syntax with an extended property of type string and that works fine, so I think the fact that this is a binary property is relevant to the problem.
I also faced to this problem. But I try to search for /messages against mapi property SearchKey.
I was thinking to use something like:
https://graph.microsoft.com/v1.0/me/messages?$filter=singleValueExtendedProperties%2FAny(ep%3A%20ep%2Fid%20eq%20'Binary%200x300B'%20and%20ep%2Fvalue%20eq%20'yxum+DwfxUy13C4qs5R6ig==')
According to https://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/part2-url-conventions/odata-v4.0-errata03-os-part2-url-conventions-complete.html#_Toc453752358
"The six comparison operators can be used with all primitive values except Edm.Binary, Edm.Stream, and the Edm.Geo types."
So I assume that binary should be casted or decoded from base64 somehow, or it's impossible at all.
UPDATE:
So I finally figure it out.
Let's say I got the value of singleValueExtendedProperty as:
{
"id": "Binary 0x300b",
"value": "yxum+DwfxUy13C4qs5R6ig=="
}
And I wanted to find message by value of this property. The problem here is that '+' should be encoded if exists. Also value should be casted to Edm.Binary. Correct query looks like this:
https://graph.microsoft.com/v1.0/me/messages?$filter=singleValueExtendedProperties%2FAny(ep%3A%20ep%2Fid%20eq%20'Binary%200x300B'%20and%20cast(%20ep%2Fvalue,Edm.Binary)%20eq%20binary'yxum%2BDwfxUy13C4qs5R6ig==')
I am using LoadRunner version 12.02 - Build 2739
Looking at an old, yet correct 'guide' shows that I have used the statements correctly (3rd Point, around 1/3rd of the way down the page, inside the code block - the atoi statement).
But I am still unable to convert the _count parameter to an int-Variable.
In the script, before the call is made;
web_reg_save_param(
"ParamName=rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
After the web call the save_param function is placed before, the output log shows;
Notify: Saving Parameter "ParamName=rotaPeople_count = 21".
Inside the script, after the call is made, and the count has been totaled;
lr_output_message("RP_C:%d",lr_eval_string("{rotaPeople_count}"));
lr_output_message("RP_C:%s",lr_eval_string("{rotaPeople_count}"));
peoplesCount = atoi(lr_eval_string("{rotaPeople_count}"));
lr_output_message("PC:%d",peoplesCount);
In the logs after the above executions are made;
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
RP_C:110826864
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
RP_C:{rotaPeople_count}
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
PC:0
Anyone have any ideas?
Note: The Warning messages are expected
Note: Workaround: Used web_reg_save_param_regex() and created a regular expression. Using the returned _count parameter within a for-loop worked. Keeping question open, as the original problem still persists
The problem is that you use a soon to be deprecated API web_reg_save_param which does not support the ParamName syntax. In this API the second parameter is always the parameter name and therefore the correct use would be:
web_reg_save_param(
"rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
The proper API to use is web_reg_save_param_ex which does support the syntax you used so the call should look like:
web_reg_save_param_ex(
"ParamName=rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
Then the rest of your code should work properly.
I am not sure what you are doing but you might want to take a look at the somewhat unknown API lr_paramarr_random which will automatically pull a random value from the parameters array.
This should help you
web_reg_save_param(
"rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
lr_output_message("PC:%d",atoi(lr_eval_string("{rotaPeople_count}")));
You are using ord=all,see the run time data which value you want to capture,If you want to capture the 10th value please use ord=10,automatically this warning will remove from output log.
Example for capturing an array of dynamic values:
Action()
{
int i;
int ncount;
char ParamName[100];
web_set_sockets_option("SSL_VERSION", "TLS");
web_reg_save_param("trackingno","LB=;","RB= (NTN 0430)","search=All","ord=all",LAST);
web_submit_data("barcode.pl",
"Action=http://qtetools.rmtc.fedex.com/barcode/cgi-bin/barcode.pl",
"Method=POST",
"TargetFrame=",
"RecContentType=text/html",
"Referer=http://qtetools.rmtc.fedex.com/barcode/html/barcode.shtml",
"Snapshot=t2.inf",
"Mode=HTML",
ITEMDATA,
"Name=formcode", "Value=0430", ENDITEM,
"Name=count", "Value=10", ENDITEM,
"Name=narrow", "Value=2", ENDITEM,
LAST);
ncount= atoi(lr_eval_string("{trackingno_count}"));
for (i =1;i <= ncount;i++)
{
sprintf(ParamName, "{trackingno_%d}", i);
lr_output_message("Value of %s: %s",ParamName,lr_eval_string(ParamName));
}
return 0;
}
I have a page that contains a login form. I am calling a separate function (which resides in a separate .js file) on the onsubmit event of the form. Below is the function
var LoginClick = function() {
// Omniture Code
s.linkTrackVars="events, eVar1";
s.linkTrackEvents="event1";
s.events="event1";
s.eVar1="Login";
s.tl(true, "o", "Login Clicks");
};
while the events data is getting passed on the s.tl call, the evar1 value turns up as "none" in the conversion report. I used a packet sniffer (omnibug) to check the values being passed. Even though s.eVar1 is assigned the value "Login" it does not pass that value.
Ofcourse, s.t() works well (evar value gets passed) but I dont want to do that.
I have tried s.tl(this, "o"...) which doesnt work either.
What am I doing wrong here?
Appreciate your time and help.
remove the space between the comma and eVar1
s.linkTrackVars="events, eVar1"
should be
s.linkTrackVars="events,eVar1"
There is a method I have been calling:
t1, t2 = LSL:GetDiffItem(item)
where the method is declared as:
GetDiffID(item, ignoreEnchant, ignoreGem, red, yellow, blue, meta, ignorePris)
Now I want to pass additional parameters, skipping some:
item, ignoreEnchant, ignoreGem, red, yellow, blue, meta, ignorePris
I tried just skipping the parameters:
t1, t2 = LSL:GetDiffItem(item, ignore, ignore, , , , , ignore)
But of course that doesn't work:
unexpected symbol near ','
So, how do I skip optional parameters in Lua?
See also
lua.org - 5.3 - Named Arguments "arguments are positional"
Pass nil. This will be identical to not ever having passed the parameter. However, be aware that the documentation states that you can do this, because most functions will not check each individual optional parameter, and only check each parameter if the previous one was provided.
You could use Named Arguments.
As said on lua.org: "This style of parameter passing is especially helpful when the function has many parameters, and most of them are optional. "
The idea is to pass all arguments as a table:
function InfoItem(item)
if item.name then
print("Name: ",item.name)
end
if item.color then
print("Color: ",item.color)
end
if item.enchant then
print("Enchant: ",item.enchant)
end
if item.specialInfo then
print(item.specialInfo)
end
end
InfoItem{name = "Internet Troll's Bane", color = "silver"}
InfoItem{name = "Death's Toenail Clipper", enchant = "unbreakable", specialInfo = "Little effort required to cut through the thickest nails."}
If you're writing your own functions (rather than using a preexisting API), the method I've used is to pass a table as the only parameter to the function, and fill in the appropriate values in that table. Assigning a metatable with the defaults as the first step in your function avoids looking up defaults at each step, but make sure users know you are overwriting the metatable on their input.
Use nil.
note that this won't work when the C code uses gettop, or relys on 'NONE' such as in a switch/case on the type, or explicity checking for none or nil instead of lua_isnoneornil.
