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

http://jsfiddle.net/sarbbottam/TUc94/

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-position&quo

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

Only allow input number value with autoNumeric.js

autoNumeric is a jQuery plugin that automatically formats currency and numbers as you type on form inputs. I used autoNumeric 1.9.21 for demo code. 1.

Import to project <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script type="text/javascript" src="js/autoNumeric.js"></script> 3. Define a function to use it <script type="text/javascript"> /* only number is accepted */ function txtNumberOnly_Mask() { var inputOrgNumber = $("#numberTxt"); inputOrgNumber.each(function() { $(this).autoNumeric({ aSep : '', aDec: '.', vMin : '0.00' }); }); } </script> 4. Call the function by event <form> <input type="text" value="" id="numberTxt"/>(only number) </form> <script ty

How to convert time between timezone in Java, Primefaces?

I use the calendar Primefaces component with timeOnly and timeZone attributes for using only hour format (HH:mm). Like this: <p:calendar id="xabsOvertimeTimeFrom" pattern="HH:mm" timeOnly="true" value="#{data.dateFrom}" timeZone="#{data.timeZone}"/> We can convert the value of #{data.dateFrom} from GMT/UTC time zone to local, conversely, from local time zone to GMT/UTC time zone. Here is my functions: package vn.nvanhuong.timezoneconverter; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.TimeZone; public class TimeZoneConverter { /** * convert a date with hour format (HH:mm) from local time zone to UTC time zone */ public static Date convertHourToUTCTimeZone(Date inputDate) throws ParseException { if(inputDate == null){ return null; } Calendar calendar = Calendar.getInstance(); calendar.setTime(inputDate); int

Just another career path

As a software engineer, I recently have heard of a lot of feedback from my colleagues and friends that they don’t see their career path or they don’t know how to move to the new levels in their company. No exception, I used to have that thinking before. In my opinion, there is a very important reason why people are struggling to find the answer because “career path is not always the job titles”. Normally, each company has its own job titles such as junior-level developer, middle-level developer, senior-level developer, teach lead, software architect, CTO, etc. Hence, it is not true that a job title is reasonable for every company. The interview is often conducted hardly to find a candidate matching the company title. If we have a good enough job title standard, the interview would take place very easily, right? Therefore, I prefer to define my own career path through what skills are gained under a job title. But wait, why do I need a career path? To me, a career is an indispensable pa
