How do I use jQuery to display multiple URLs from a database?


How do I use jQuery to display multiple URLs from a database?

I think the issue was by ths following , Your question is not very clear. If I understand it correctly, you want to parse JSON output by splitting it first, and then checking whether it's a URL.
Here's some pseudocode that might help you along:
code :
item.community_plan.split("\\:\\").each(function(url) {
    if(/^http/.test(url) {
        // Starts with http, so should be a 
        $('#jsondata').append('<h3>other links</h3><a href="'+url+'">'+url+'</a>');
    } else {
        $('#jsondata').append('<h3>other links</h3><p>'+url+'</p>');
    }
});

I think the issue was by ths following , I do have thousands of urls in my database. what I want to do is display all urls in multiple pages say number of URLS per page is 100 and alphabetically then when ever a user search for a URL info it should get updated on relevant page. for example if it is google.com then it should get updated on "G" page and no duplicate entry. how can I do this with PHP and MySQL?? , fist of all alphabetically ordered list:
code :
SELECT url_column_name 
FROM my_table 
ORDER BY url_column_name ASC

I wish did fix the issue. Take a look at the very capable Typhoeus and Hydra combo. The two make it very easy to concurrently process multiple URLs.
The "Times" example should get you up and running quickly. In the on_complete block put your code to write your statuses to the DB. You could use a thread to build and maintain the queued requests at a healthy level, or queue a set number, let them all run to completion, then loop for another group. It's up to you.
code :
#!/usr/bin/env ruby

require 'nokogiri'
require 'addressable/uri'
require 'typhoeus'

BASE_URL = ''

url = Addressable::URI.parse(BASE_URL)
resp = Typhoeus::Request.get(url.to_s)
doc = Nokogiri::HTML(resp.body)

hydra = Typhoeus::Hydra.new(:max_concurrency => 10)
doc.css('a').map{ |n| n['href'] }.select{ |href| href[/\.gz$/] }.each do |gzip|
  gzip_url = url.join(gzip)
  request = Typhoeus::Request.new(gzip_url.to_s)

  request.on_complete do |resp|
    gzip_filename = resp.request.url.split('/').last
    puts "writing #{gzip_filename}"
    File.open("gz/#{gzip_filename}", 'w') do |fo|
      fo.write resp.body
    end  
  end
  puts "queuing #{ gzip }"
  hydra.queue(request)
end

hydra.run

seems to work fine You would query the database then use a loop to display the results in the format of your choice. I assume you know how to connect to the database, so see the link below for an example of a database query and loop using PHP PDO.

this will help Let's say we have an URL looking something like this. , It would be easy. You can use the FOR LOOP.
code :
<?php
for($i=1; $i < 1000; $i++) {
    echo file_get_contents('http://domain.com/index.php?p=' . $i . '&u=A1b2C3d4E5f6G7h8I9j');
}

Hope this helps ignoring invalid urls: try ... except urllib2.HTTPError will help you with this loading several images: Iterate through your urllist and load each of those images. When successfull, draw it onto you canvas.
code :
#from urllib.request import HTTPError #py3
#from urllib2 import HTTPError #py2
#... 
def load_image_to_base64(image_url):
    """ Load an image from a web url and return its data base64 encoded"""
    image_byt = urlopen(image_url).read()
    image_b64 = base64.encodestring(image_byt)
    return image_b64

# load photos to photos list
urllist = ['http://www.okclipart.com/img16/kjlhjznjvkokwqpalupl.png', 
           'invalidurltest', 
           'http://www.okclipart.com/YouWontFindThisImage.png']
photos = []
for i, url in enumerate(urllist):
    print(i,"loading",url)
    try:
        photo = tk.PhotoImage(data=load_image_to_base64(url))
        photos.append(photo)
        print("done")
    except HTTPError as err:
        print("image not found, http error code:", err.code)
    except ValueError:
        print("invalid url", url)

# iterate through photos and put them onto the canvas
for photo in photos:
    cv.create_image(10*i, 10*i, image=photo, anchor='nw')

root.mainloop()
