At the moment I can generate pages by drawing the content with javascript based on ajax requests for JSON files which describe what is to be drawn.
The result is good, but I want users to be able to access a page such as www.example.com/SomePage where I use SomePage in javascript to display the content based on it.
Since SomePage isn't an actual existing .aspx page I get 404 error from the server. Could I capture the url path and hand it somehow to the javascript to generate the page dynamically? Thanks in advance!
You look for the HttpContext.RewritePath Method.
In a short, you read your path eg: www.example.com/SomePage
and using the HttpContext.RewritePath you translated it to
www.example.com/editor.aspx?id=SomePage
and there you have your SomePage value to use
on your javascript code
and still the url show www.example.com/SomePage

I want to load a new template page with data inserted via the previous call.
I have a list of items generated and they link to the general item page but without php all is lost.
I was thinking about using a href="page.html#itemid" then finding the item by querying the url.
Is this overthinking it? Any easier ways to do it?
I am assuming that on the current page, you have used AJAX to load all the data you need to display on the new template page, correct?
I can think of multiple ways to do this. It just depends on the nature of your data:
Have a popup instead:
You could have the new template page be a popup (instead of a real, separate page). Grey out the main page's content (via a darker, half transparent overlay) and then have this new popup div display the data you want. This is typically used on sites that want you to sign up for their newsletter, etc.
Pass the data via URL:
If you have very small amounts of data and it isn't sensitive data, you can just pass it through the parameters. Let's say page.html is the new page template you want to populate the data with. Then just have the link on the current page be page.html?itemid=123¶m2=Hi or something like that. Then, on page.html, make sure you have JS to read the parameters from the URL and display the data.
Pass the data via cookie:
Otherwise, you might just want to use JS cookies. Especially if you have a medium or larger amount of data. Store the data loaded from AJAX into cookies. If you are expecting the user to open multiple page.html templates at the same time, you might want to use an identifier and pass it to each one, such as page.html?itemid=1 and page.html?itemid=2 etc. Then have that page.html's JS look up the appropriate cookie based on the URL's parameter id.
Do be careful and use best practices if handling sensitive data.
I am using GET and POST methods for getting data from the server and getting response using request.send(object);.
However my requirements changed, I need to use request.render('pageName',object); but the render method refreshes my page but I only want to refresh a particular <div> section. I read on this link https://www.npmjs.com/package/ejs but I am not able to refresh only particular section without refreshing the entire page.
If you want to redraw only a part of the page then you probably need some kind of client-side rendering for your templates. You fetch the data from the server using GET just like you mentioned and then do the actual drawing of the page on the client instead of sending HTML with request.render.
I have used php simple html dom to no success on this issue.
Now I have gone to DOMDocument and DOMXpath and this does seem promising.
Here is my issue:
I am trying to scrape data from a page which is loaded via a web service request after the page initially shows. It is only milliseconds but because of this, normal scraping shows a template value as opposed to the actual data.
I have found the endpoint url using chrome developer network settings. So if I enter that url into the browser address bar the data displays nicely in JSON format. All Good.
My problem arises because any time the site is re-visited or the page refreshed, the suffix of the endpoint url is randomly-generated so I can't hard-code this url into my php file. For example the end of the url is "?=253648592" on first visit but on refresh it could be "?=375482910". The base of the url is static.
Without getting into headless browsers (I tried and MY head hurts!) is there a way to have Xpath find this random url when the page loads?
Sorry for being so long-winded but I wanted to explain as best I could.
It's probably much easier and faster to just use a regex if you only need one item/value from the HTML. I would like to give an example but therefor I would need a more extended snippet of how the HTML looks like that contains the endpoint that you want to fetch.
Is it possible to give a snippet of the HTML that contains the endpoint?
I thought this would be easy but I guess I was wrong. I have a url;
http://www.example.com/aa/bb.html?uid=123
using javascript jquery and html, I am able to retrieve data from a json api with the uid in the sample url above. However, I don't want that url displayed like that in the address bar after the data has been parsed. Rather, I need it to display as;
http://www.example.com/aa/item-title
where item-titleis the title of the data referenced by uid=123.
A php mod-rewrite would have been ideal, but this project does not make use of server side scripting.
Thanks in advance
If you change or modify the URL then the browser try to fetch data fro the new URL. You can do something with the part of URL after # mark.
Like :
http://www.example.com/aa/bb.html?uid=123#old_part
to
http://www.example.com/aa/bb.html?uid=123#newpart
I can see only one solution to your problem as you don't want to use mod_rewrite. You can redirect from first page just changing the URL based on the given uid value to the next page you want to display.
First page - read parameter uid and build the redirect URL based on the title(not any other stuff in your first URL page)
Redirect to the built URL
In redirected page do the rest of page specific stuff.
How should I proceed in achieving the following:
I need to get the data from another server which is a jsp page it has the data related to the information i want to show in tooltip. The code for this is working and I can make ajax call to get the response.
The concern is that I want the contents of qtip library to fit in the page since the page doesn't allow cross domain contents. If I will try to just reference the contents of qtip saved on my website(the domain is different from the page which I am using) it wont allow to do this. so is it fine embedding the contents in the main form or there is some other optimal way?
Similar question was asked:
How to display information returned by ajax call in a tooltip
If you can't reach cross domain via AJAX you can always uses an intermediary script (in your case Java) to output a buffer containing the information you want in the qTip.
Script calls digest.jsp?params=someparameters
digest.jsp fetchs the information from any domain it needs.
outputs the information in a buffer in XML o JSON
with javascript you parse the information an put it in the option attribute.
If it doesn't work for you nor you want to do it you can always relay in putting the information in each title="" attribute in each option.
