Adding a default text to the beginning of an text area

I have a text area where I can enter a SQL statement. The text "SELECT TOP 1" is used at the begining of the sql statement as a default prefix that can not be removed.

In order to archive this functionality, I found three options:

1. Use an inputMask and build a pattern for the entered text. We can use the prefix inside the text area:

2. Create an javascript event listener on event "input" and calculate to prevent the prefix is removed

3. Use another html tag like "div"/"span" that contains the prefix and calculate the suitable position

+ Tag "span": http://jsfiddle.net/4YzZy/
+ Tag "div": http://jsfiddle.net/215b34fs/

I chose the 3rd approach with tag "div" because it's the most easiest solution and suitable for me at that monment.

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent"> <div id="child"> </div> </div> And, CSS: #parent{ position: relative; overflow:hidden; } #child{ position: absolute; top: -1; right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-positi...

Selenium - Override javascript functions to ignore downloading process

I have got an issue with downloading process on IE 8. This browser blocks my automatic-download functionality on my app so that I could not work with my test case any more after that. In my case, I didn't care about the file is downloaded or not, I just focus on the result after downloading process finished successfully. Therefore, I found a solution to ignore this process so that I can work normally. I use Primefaces, here is the remote command to trigger the download process <p:remoteCommand name="cmdGenerateDocument" actionListener="#{logic.onGenerateDocument}" update="xrflDocumentCreationPanel" oncomplete="clickDownloadButton();"/> The following is my test case: @Test public void shouldUpdateStep6ToWarningIfStep1IsValidAfterFinished(){ MainPage mainPage = new MainPage(); waitForLoading(mainPage.getDriver()); EmployeeDetailPage empDetailPage = new EmployeeDetailPage(); waitForLoading(empDetailPage.getDriver()); e...

Creating a Chatbot with RiveScript in Java

Motivation "Artificial Intelligence (AI) is considered a major innovation that could disrupt many things. Some people even compare it to the Internet. A large investor firm predicted that some AI startups could become the next Apple, Google or Amazon within five years" - Prof. John Vu, Carnegie Mellon University. Using chatbots to support our daily tasks is super useful and interesting. In fact, "Jenkins CI, Jira Cloud, and Bitbucket" have been becoming must-have apps in Slack of my team these days. There are some existing approaches for chatbots including pattern matching, algorithms, and neutral networks. RiveScript is a scripting language using "pattern matching" as a simple and powerful approach for building up a Chabot. Architecture Actually, it was flexible to choose a programming language for the used Rivescript interpreter like Java, Go, Javascript, Python, and Perl. I went with Java. Used Technologies and Tools Oracle JDK 1.8...

BarcampSaigon 2015

Barcamp Saigon is one of my most expected events of the year. This year, it took place at RMIT university. As usual, it brought many useful topics to the community. Here is all topics that I have attended. Scale it! - Lars Jankowfsky Lars is founder of 8bitrockr.com How do we make a decision correctly? It is hard to know that until we try and measure it. He gave an example about how good an app was. And, most of people thought that the app with nice user interfaces is good at the first look. But it is not correct because it is only true until we try to use it, even the nice GUI app sometime is not good at UX, functionalities, etc. The key of success for working in team is collaboration. We can not only base on the experience of members likes: "In my opinions| As I know.... this is the best way..bla..bla.." but we should test it. Therefore, manually testing as well as automation testing is more and more necessary nowadays. "Don't think, just try...
