QUESTION
I have set up DB2 as NoSQL storage (following https://www.ibm.com/developerworks/data/library/techarticle/dm-1306nosqlforjson4/index.html). The premise by IBM is that any application talking to MongoDB can switch to DB2 if we add the Wire Listener in between.
The layout is: Client app ----> Wire listener ----> DB2
Wire listener is started with the following command:

I have a form with a few fields. When the user checks the checkbox, I want the data in 3 of the fields to be set to blank.
Currently, it's not working the way I was hoping. I am using DOM development to achieve this.
...ANSWER
Answered 2020-Jul-06 at 13:58I assume you want to update the inputs when the checkbox is clicked. In that case you'll need to add an event listener.

QUESTION
I have a table generated using an array of objects. I am having a hard time figuring out how to use computed properties to filter the array of objects. I am using VuE.js. I'm not sure how to properly use the filter() in my computed properties to filter the table.
...ANSWER
Answered 2019-Nov-30 at 20:08Computed properties have to return a value, and you can use it as same as data and props. So what you need to do is return the result of the filter. For the case with no search
option, you can return raw programs
without the filter.
The computed property will be like this:
(if you filter the programs by it's funding
attribute.)
QUESTION
I have a table that was generated dynamically using Vuejs. It has input elements in cells that render as readOnly. Each element has an 'edit' button and when it is click, it changes to 'save' and enables the input elements of that row for editing. When save is clicked, I would like to capture the new value entered and the previous value. I formatted my date field as mm/dd/yy
from the original which is in this format 2019-10-10T07:00:00Z
I am able to successfully format the date using momentjs but it doesn't seem to stick. The value entered is different from when I alert it. Any ideas of what I'm doing wrong? Do I need to refactor my code to allow me to do this because this has to be done for each field, which is to get access to new value and previous value.
ANSWER
Answered 2019-Oct-29 at 18:52If you want it to behave in a way that the data in the input is different than what is being shown you'll have to decouple the input from the data.
v-model
needs to havea a variable assigned so that the input can update its value. Right now you're using v-model="formatDate(program)"
which cannot work, because passing a static result of the function cannot be reactive.
There are several ways of accomplishing this. Here is an example that just gets it done. There's certainly room for improvement and alternative implementations...
replacev-model
with value
and event listeners
This defines where the value comes from; a function generating a formated date. (note that using a function in template for rendering is not good practice. it's better to do this once and use a cached value, so that the value doesn't have to be recalculated)
QUESTION
I have a table that is dynamically being rendered with data in a readonly input box in each cell. In the first cell, there is an edit button. When the user clicks edit, the readonly on the input boxes should be disabled so data can be entered in each cell. The edit button should be hidden and the save button should show. When the user clicks save, it should call a method that can use the data (save to a database or something).
I thought I could use the event and drill down to the target but it's an array and I'm not sure what to do. Any ideas?
...ANSWER
Answered 2019-Oct-27 at 04:38Add a readonly attribute to the elements in an array. Upon clicking the edit button, set the readonly attribute of the elements in the array to false.
QUESTION
I'm developping a web UI in javascript. Data are stored in a remote DB, accessed by an API. I need extra data that are not stored in the DB, and I can't create any table or store any structured data in it.
I started by creating arrays in the code but it quickly becomes unreadable and overwhelming, leading to an awful mix of code and data in my JS files.
So I created a JSON file to store them, looking like that.
...ANSWER
Answered 2019-Oct-12 at 01:32The answer is so simple, I ashamed.
- Add a variable declaration at the beginning of the JSON data file.
QUESTION
I am trying to insert a document into oracle12c using SODA lib using example.
I have created a collection using SODA. Now I am trying to insert a document, But I am getting the exception while inserting doc.
...ANSWER
Answered 2019-Sep-19 at 09:07The issue is due to the mismatch of ojdbc.jar
.
The official document says,
If you're using JDK8 or above, you could use ojdbc8.jar that ships with Oracle Database 18c. Alternatively, you can also use ojdbc8.jar that ships with OracleDatabase 12.2.0.1. If you're still on JDK7 or even JDK6, you can use ojdbc7.jar or ojdbc6.jar respectively. These ship with Oracle Database 12.1.0.2, and are downloadable from this page.
My project is using JDK 7 and project has custom ojdbc6 jar and version 11.3. Then I replace ojdbc7.jar
(downloaded from this link.) with my custom jar.
Due to this change above exception is gone and the code works well.
