Want to add Placeholder to Dynamically Generated Field Angular Material

I have an Angular Reactive form in which the input fields are generated dynamically
I want to change the placeholder of input fields which are dynamically generated
based upon what user has selected in the first textbox.

So Suppose User typed anything in first textbox so based upon that i want to change the value of Second textbox and so on..

Please note all the input fields are dynamically generated so i cannot just update the placeholder like this:
somePlaceholder : string = “new value”;

Is using JavaScript to dynamically add ads from Google Adsense on a page allowed by Google?

I want to use this way to add an ads segment on my pages:

 <ins class="adsbygoogle"

Is this okay? Do I need to be aware of anything?


seo – How can a search engine crawl a dynamically generated website?

Short answer: That PHP code is run on the server before sending the response to the crawler, so by the time the page reaches the crawler, all that info is already populated.

For sites written using server-side languages such as your example, here’s the full lifecycle when a user visits a page:

  1. The user’s browser sends an HTTP request to the server for a certain path (such as /an/example/page/).

  2. The server receives the request and determines the appropriate server-side code to run to generate the page. It executes this code, if any (or none if it’s a static site).

  3. The server sends the final generated, by that point static HTML page back to the user’s browser.

Note that all the code is finished running on the server before the server actually sends any information back to the user’s browser (or a web crawler).

Things are a little different when the page is generated in part by client-side code (JavaScript) instead, which is a topic for a different discussion.

image – How to give the img src dynamically in the html without using external javascript file

I want an image adjacent to the card number. Cards are of different type – mastercard , visa , american express. So my html goes like this( I’am working on vue framework)

<img src="https://stackoverflow.com/assets/images/brand-logos/mastercard.png" class="payment-card-icon" alt="card-logo"> 

I have an api which gives me a key-value pair like – card_brand: “visa” or card_brand: “mastercard”. I want to use this dynamically available variable to render the images in the html. I know i can use v-if for each case and have a img there. But I wanted to have optimised code if possible.

I wanted the mastercard.png as dynamic variable. maybe like {{user.card_brand}} in place of that. I know this method wont work. I can save the images in the names i wish to achieve this. Is there a way t do it ?

Web Scraping Dynamically Generated Content Python

This is a small web scraping project I made in 2 hours that targets the website remote.co . I am looking forward for improvements in my code. I know about the inconsistency with the WebDriverWait and time.sleep() waits, but when I used the WebDriverWait to wait until the load_more button was clickable and ran the program selenium crashed my webdriver window and continuously spammed my terminal window with 20-30 lines of seemingly useless text.

import scrapy   
from selenium import webdriver

from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import ElementClickInterceptedException

    name = 'jobs'
    start_urls = (f'https://remote.co/remote-jobs/search/?search_keywords={job_title}')

    def __init__(self):
        self.driver = webdriver.Chrome(r'C:Usersleaguchromedriver.exe')

    def parse(self, response):

            load_more = WebDriverWait(self.driver, 10).until(

        except TimeoutException:
            self.log("Timeout - Couldn't load the page!")

        while True:
                load_more = self.driver.find_element_by_css_selector('a.load_more_jobs')
            except (ElementNotInteractableException, ElementClickInterceptedException):
                    close_button = WebDriverWait(self.driver, 6).until(
                        EC.element_to_be_clickable((By.CSS_SELECTOR, '#om-oqulaezshgjig4mgnmcn-optin > div > button'))

Java – Possibility of dynamically generated prepared statements and stored procedure SQL injection?

I am working on a Java application that generates SQL prepared statements and stored procedure query strings using user input and runs with PreparedStatement.execute () or CallableStatement.execute ()

String query = "{? = call UserSuppliedStoredProcName(?,?)}"

Is there a way for the user to insert a SQL injection before or after the definition of the stored procedure? I have tried the cases below and all of them throw the exception.

String query = "{? = call UserSuppliedStoredProcName(?,?)} or select * from login_table"
String query = "{? = call UserSuppliedStoredProcName(?,?)} AND select * from login_table"
String query = "{select * from login_table UNION ? = call UserSuppliedStoredProcName(?,?)}"
String query = "{sleep(1) or ? = call UserSuppliedStoredProcName(?,?)}"

woocommerce – Dynamically load the list of products in the subcategory

I have a product page, where I want to list all the products in a subcategory.

Category> Mtn> Series <- product page level.

Category> Mtn> Series> Model <- product subcategory level.

            'post_type' => 'product', 
            'posts_per_page' => 8,
            'product_cat' => '**SubCategory goes here**',

            'meta_key'  => '_price',
            'order' => 'asc'

$loop = new WP_Query( $args );
            while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

show the producdts here. 


the above code works when I hardcode the product_cat in the field,

tiles – Is it possible to build TileMaps dynamically from a database?

So basically the game I create allows users to create their own tile maps, so I want the server to respond with tilemap coordinates if / when a user enters their custom world.

Is it possible to do with GoDot, if so, are there tutorials on how to tackle this type of task?
