I want to use arrays and relative targeting to be able to add new templates without having to retarget in every new template. I could use 'getElementById' inside the function to write the json into an element, but then I have absolute targeting.
I tried using global variables, but I could not make it work.
The variables in my js code are limited to the scope of the function and cannot be used outside of it. Problems that I know of but can't find a solution to: I'm new to frontend coding and try hard to wrap my head around these technologies. I'm using gulp to build the final output files. Understanding these architecture concepts is way harder then learning the code.
These templates are very basic, like replacing h1 and p strings or image paths. Skip the extra JSON file and put the data into a javascript file (using gulp to concatenate and minify everything into one javascript file) Figure out a way to compile the JSON with gulp and have the data available when the pug is being compiled into html. I want to write templates in pug, that are populated with data from an external json file.
Thus if you can't add a event listener to them how are you able to comment, like, or react to those post.I don't understand how to use json as a simple database for my templates. Just think any time you post something on Facebook, Twitter, or LinkedIn you are essential dynamically adding a element to a page. You don't need me to tell you of all the possibility you can use this function with or how commonly this is used. Selenium webdriver has ability to track different events such as 'beforeNavigateTo', 'afterNavigateTo', 'beforeClickOn', 'afterClickOn', 'onException' and so on. It also plays an important role in analyzing results and helps us in debugging issues if we encounter any. Well since you now know the basics on how to add an event listener to a dynamically added element. Webdriver events are helpful to view the events triggered by webdriver. The third parameter is a callback value, in which I made a function that will turn the new button background yellow.Īs you can see I was able to add an event listener on my "new button", if when I click on the new button it will change its background to yellow. Then for the on function the first parameter is action value "click", the second parameter will be a child-selector name which in this case the class of the new button added(see line 3). First I create a event listener for the #content which if you remember is the main selector id for the empty div on the html document. How can we add an event listener to that new button ? Line 15 is the event listener that adds a new button every time I click on "click me". Therefore line 1-5 it's just me making a function called "addButton" that uses render function to make a new button called "new button". In the JavaScript file, in line 8 I made a render function that should append a string to an element, which in this case will be on the empty div from earlier.
I have a simple HTML document that includes a button named "click me" and also an empty div. Thank you for checking out my article on learning how to add event listener to dynamically added element. Welcome to my second installment of "How to" guides
