I am working on some legacy code and trying to get everything under control.
I have some stored procedure that contains javascript. Something like
SET #result = #result + '<script>
$(document).ready(function () {'
I have created a SSDT project to keep track of all my database objects. However if I try and publish it SQLCMD will throw a fit as it is getting confused between javascript and its [$(DatabaseName)] syntax.
Is it possible to escape my $ so SQLCMD will correctly parse my SQL code?

I am currently using DYMO Label Printing software to print labels. I have previously had the label XML template stored as plain text and it worked fine. But recently I have decided to move to a more dynamic approach so that labels can be edited and modified directly from the database.
So I am currently storing the XML label templates in a simple SQL database table. I set up the viewmodel that contains the XML information, and then access it in Javascript when printing in the View itself.
I previously just tried this:
try {
var labelXml = "#Viewmodel.XMLString"; //Open XML from Viewmodel directly
var labelD = dymo.label.framework.openLabelXml(labelXml);
}
catch(err) {
alert("Couldn't load label");
return;
}
And that did not work.
I did some research and also tried this (placing viewmodel in "text/plain") and then accessing it above.
<script>
try {
var labelXml = $('#label_XML').text();
var labelD = dymo.label.framework.openLabelXml(labelXml);
}
catch(err) {
alert("Couldn't load label");
return;
}
</script>
<script id="label_XML" type="text/plain">
#Viewmodel.XML
</script>
Both of these methods result in this: (<> replaced with < and >)
How can I simply access a XML string in the database from the viewmodel while avoiding any unwanted conversions? Thanks.
Using #Html.Raw results in this problem:
The first line is read correctly but with each line break it reads as code instead of text. I put the original #Html.Raw in quotes, is there a way to prevent it from attempting to read it as code as shown above?
It looks like you are struggling with HTML Encoding. Have you tried using #Html.Raw(Viewmodel.XML)? That helper should prevent MVC from HTML encoding the content.
Depending on where that XML content comes from, you might be creating an XSS risk, so be careful how you use Html.Raw and consider reading more about it if it does solve this problem for you Is there a risk in using #Html.Raw?
I have a string like this:
{
WABrowserId: '"hTCl7asDPe/EIymrQC57Hg=="',
WASecretBundle: '{"key":"o65mhfj8XZpuCIIgamAdsaibobs0HKiiBCwTAn36qms=","encKey":"nw5vM2sa05Eh94boiPO5r2qi5fS7CZmJwNNWgIsEj08=","macKey":"o65mhfj8XZpuCIIgamAd3Eibobs0HKiiBCwTAn36qms="}',
WAToken1: '"ArRasrW9r63ByrbKDAauchBnzEUYOO9q0HTWJYfG0RM="',

}
I got an error message like this:
UnhandledPromiseRejectionWarning: Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WABrowserId = '"hTCl7AYDPe/EIymrQC57Hg=="', WASecretBundle = '{"key":"o' at line 1
How can I insert this string into a MySQL database with a Node.js script?
You can't insert normal JS object, you need to parse into JSON using JSON.stringify(obj) function then insert into the database.
you might also need to remove the single quotes and use double quotes.
Goal
Transform HTML extracted from Telligent (an extranet platform) to plain text and send to Slack
Setup
A Telligent webhook is triggered when an event occurs. An Azure Logic App receives the event JSON. The JSON value is in HTML. A JavaScript Azure Function inside the Azure Logic App pipeline transforms the JSON value to plain text. The final step in the pipeline posts the plain text in Slack.
Example of incoming code to the Azure Function
"body": "<p>" '</p><div style=\"clear:both;\"></div>"
Transformation method
This is the basic code in the Azure Function. I have left out parts that seem irrelevant to this question but can provide the entire script if that is necessary.
module.exports = function (context, data) {
var html = data.body;
// Change HTML to plain text
var text = JSON.stringify(html.body);
var noHtml = text.replace(/<(?:.|\n)*?>/gm, '');
var noHtmlEncodeSingleQuote = noHtml.replace(/'/g, "'");
var noHtmlEncodeDoubleQuote = noHtmlEncodeSingleQuote.replace(/"/g, "REPLACEMENT");
// Compile body for Slack
var readyString = "Slack text: " + noHtmlEncodeDoubleQuote;
// Response of the function to be used later
context.res = {
body: readyString
};
context.done();
};
Results
The single quote is replaced successfully and resolves accurately when posted in Slack.
The following replacement methods for the double quote throw a Status: 500 Internal Server Error within the Azure Function.
Unsuccessful replacement methods
"\""
'"'
"
"'"'"
"["]"
"(")"
Putting these replacement methods in their own var also throws the same error. E.g.:
var replace = "\""
...
var noHtmlEncodeDoubleQuote = noHtmlEncodeSingleQuote.replace(/"/g, replace);
The code appears to be correct because when I replace " with something like abc, the replacement is successful.
Thank you
Please forgive my JavaScript as I am not a programmer and am seeking to streamline a process for my job. However I am grateful for any advice both about the code or my entire approach.
Generally, you don't want to try to parse HTML with regular expressions or string replacement. There are just too many things that can go wrong. See this now famous StackOverflow answer. (It was even made into a T-Shirt.)
Instead, you should use a technique that is purposefully built for this purpose. If you were in a web browser, you could use the techniques described in the answers to this question. But in Azure Functions, your JavaScript doesn't run in a browser, it runs in a Node JS environment. Therefore, you need will need to use a library such as Cheerio or htmlparser2 (and others).
Here is an example using Cheerio:
var cheerio = require('cheerio');
var text = cheerio.load(html.body).text();
Also, regarding this part:
... as I am not a programmer ...
Yes you are. You are clearly programming right now. Anyone who writes code is a programmer. There is no club or secret handshake. We all start out exactly like this. Good job asking questions, and good luck on your journey!
I'm working with sensor units outfield that spit out data in the form of native text files and have a database created with pre-defined tags. E.G mm, level, voltage. The text file I'm using is pretty unstructured with the data being on the right side of the header separated by semicolon delimiters.
I want to try and import the content into the database where each header matches the tag name and the values are inserted into that tag consecutively. I'm wondering if there's a possible solution or maybe even some tips on how i can achieve this?
Currently i have been working with PHP but haven't gotten to far, is it the best language to use for such a method? Or would javascript be preferred?

database table Tag_data Structure
You can do like this
LOAD DATA INFILE '/yourtext.txt' INTO TABLE TABLENAME;
Your text will be pretty hard to explode every value with it's parameter because every single word end with ; so, first try to make your text file like parameter:value; or parameter=value; or parameter_value; then you can read the content of this file with this php function $content = file_get_contents("path/text_file_name.txt"); now the value of $content variable is equal to the entire text of your file hence, you can split this variable into an array with $splittedcontent = explode(";" , $content); every parameter:value is a parameter in this array like $splittedcontent[0] = parameter0:value0, $splittedcontent[1] = parameter1:value1 and so on, now you can use for loop throw this array and make what your need in you database..
I hope this will help you.
I am trying to use the beanshell script posted here to get the path of the jmx that is being run in my jmeter test - Access to JMeter script path
It is working and if I log the output of the path when set by beanshell or view the variables with the debugger I get the path to the script displayed as I expected -
c:\my\path\to\script
but when I then try to pass that variable into sendKeys, the slashes "\" are being removed so -
c:mypathtoscript
And this doesn't work so I am unable to attach/upload my file..
Sure I am missing something stupid
Thanks
Needed to user vars.put to put the JMeter UDV value into a Javascript variable, then use javascript concatenate to link it all together.
There are at least 2 ways to get this done without using Beanshell:
Call FileServer methods from WebDriver Sampler:
someElement.sendKeys(org.apache.jmeter.services.FileServer.getFileServer().getBaseDir())
Get the value from JMeterVariables
var vars = org.apache.jmeter.threads.JMeterContextService.getContext().getVariables()
someElement.sendKeys(vars.get('homepath'))
Example full code:
WDS.sampleResult.sampleStart()
WDS.browser.get('http://ya.ru')
var searchInput = WDS.browser.findElement(org.openqa.selenium.By.id('text'))
//directly access function from JavaScript
searchInput.sendKeys(org.apache.jmeter.services.FileServer.getFileServer().getBaseDir())
//alternative way - getting the value from JMeter Variables
var vars = org.apache.jmeter.threads.JMeterContextService.getContext().getVariables()
searchInput.sendKeys(vars.get('homepath'))
WDS.sampleResult.sampleEnd()
