I have an existing website composed of individual pages (each page is a different tool that requires some user input (ie forms), and each with it's own set of javascript functions to populate dropdown lists, etc on that page). Each of the tools is accessed from the main index.html.
Instead of each tool being its own "stand-alone" page that is invoked from index.html, I'd like each tool to be displayed in an iFrame instead on the main page. This way the main page remains static, while only updating the iframe with whatever tool the user selects. So say on the main index page, I have a 3 tools menu (collect logs, collect KPIs, collect status), along with an iFrame. If the user selects collect logs for example, the menu containing "collect logs" stays there, but the "collect logs" page is displayed in the iFrame.
My problem is that all the HTML content works fine, but none of the javascript code in the selected tool page works (ie none of the drop downs get populated since it's the javascript code in the page that does that by reading a file on the server).
Is there an easy way to port each tool page (html+javascript) to an iFrame without having to re-write tons of code (in my naivety I thought simply invoking the page inside an iFrame using target='' in the href would work)? Or is there a better method of accomplishing what I'm trying to do? Maybe iFrame isn't the solution.
Content in iframes remain autonomous from the wrapper app, so it makes sense that it's not working correctly. Other than building a listener for a click event associated with the div wrapped around the iframe, the iframe document isn't accessible if it points to a different origin. (See [same-origin policy]
(https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy))
To stay with simple html/css/js solution:
You can use a regular div to wrap each 'stand-alone' content and then just use whatever button/navigation target you have display that div and hide the previous by changing their css display style with the onClick event.
More invasive option:
You may want to consider using a more modular JS approach, like React JS, to build components vs pages and utilize React's structure to toggle components.
With react you can render each 'tool' when the user selects it . You would be able to utilize React component state as well to help in storing data and such for the life-cycle of the component.

So I'm constructing a induction-type webpage, I'm using a template which someone has already previously built in order to see how it fits my needs
Essentially, it includes a dynamic page switcher that uses previous and next buttons to swap out the body content without having to load another entire page.
EXAMPLE: https://css-tricks.com/examples/DynamicPage/
Upon clicking a hyperlink inside the main content, the body will show the correct content from the external pages. However, if I click either of the navigation links up top ("Home >> Inductions >>") the link is not opened as a new page, but instead I think ajax attempts to load that page inside the ajax-body section.
Specifically in the codepen, this is the navbar I'm mentioning which I do NOT want ajax to work on. I've tried multiple fixes but finally throwing my hands in the air.
<nav id="location">Home >> Inductions >> Vehicle 1</nav>
What I am aiming to build is attempt something like this: https://css-tricks.com/examples/DynamicPage/
This is the creator showing how its made, if I am unable to describe it as well as I should: https://css-tricks.com/dynamic-page-replacing-content/
I made a codepen the best I could, without being able to upload the other 2 pages which ajax will load the bodies from - https://codepen.io/dylan-mclean-the-vuer/pen/XWbONyP
Just imagine that clicking the 'prev' or 'next' will load a body inside the contained from external HTML docs. I couldn't figure out how to use multiple HTML files. I still need to make a proper prev/next in JS somehow still, just will take some time! Currently, prev just links to one HTML doc and next links to another.
Keep in mind I'm still at the diploma-grad coding level, so I'm sorry if I'm missing an obvious solution, or if its too messy to understand!
We provide live chat service to our customers. customer just copy some code and put in their footer. then they can have video chat, cobrowsing and many things..
but problem comes when user switch from page to page. so we have resume functionality as well. but thats not robost solution.
So i've come to two solution.
1. Iframe solution
i'll give client a some.html file which he'll need to upload to their root url, then upon video chat and cobrowse we load that page in some.html's iframe and chat appear in some.html
so that work well. chat box apprear seamlessly no page reload effects came in. and as its on same domain i can access all contents of iframe.
2. Another hack solution (not implemented yet, looks good solution)
i was thinking that instead of redirecting user to new page (some.html)
i should clear all contents of current page and load same url in one iframe within the page.
i think that will work well. but i affraid that some client might be using complex js based web app. so if i remove complete body from their page they might have problems.
as much as i know i can remove all dom nodes with their events handlers as well. but is their way to clean js runtime. so all js objects will destroyed and removed from scope so no longer run.
so is there a ways to clear any page completely with all its html and associated java-script as well. means reset page to blank.
Finally i found that there is no way to reset page.. but got another way to make it done.
upon need we can redirect user to same page with query string that identity that its reload for iframe, we put small bit of another code at head which remove all dom before loading dom, css, js.. and create just one iframe of same url.
thus it allows me, have user see no change in url, user browse website as normal without any problem and my chatbox always be there in same state across all pages.
will make it live soon on tagove.com
Why don't you empty the HTML page using empty() function of jquery first,
Then remove/update the link i.e.<script src="...."></script> so that the HTML has no dependency on that javascript and that way it won't be able to Modify the DOM.
And then try to build a javascript program to remove any file in the folder which is isolated(No calling, No dependency, no connection whatsoever)
I know this has been asked several times, but I just can't figure out how to change the url or render a new html and make it seem as if you never leave the site.
I want to do exactly what this site does:
http://uncharted.sunbrella.com/
Does it load all the content and just change the visible objects via javascript? Do they use angular states? I can't figure out how to get that effect of seamless transition between sections of websites.
Based on their page source code, it doesn't look like they're using angular, but you certainly could use it. If you did, I would recommend using ui router with multiple views on the page.
The secret to loading html dynamically is by using ajax to request data on the fly and updating the dom via javascript.
The site you referenced used css to make the page responsive and to prevent you from scrolling until you clicked a link. After clicking it looks like the content loaded outside of the view port so you don't see the data loading until you scroll.
Long story short, to point you in the right direction, I would urge you to learn more about ajax loading and css dom manipulations. If you are familiar with Angular, checkout ui router as it would allow you to easily setup multiple views on a page.
I am developing a retail store website and am using an html page with JavaScript. I want to use iFrames. The main page (Page1) is made up of a banner, a menu on the top and an iFrame below. For clarity I will call this iFrame1. In iFrame1 I have an html page (Page2) that contains another iFrame. I will call this iFrame2.
Page 1 has a top level menu detailing departments for example curtains, cushions, clothes etc. Selecting one of these items brings up another page (Page2) with a 2nd level menu based upon the selection within the first menu and a ListView of relevant sub headings and images pulled from the database. Making a selection from the menu in Page2 will change the “Where~ clause in the Select SQL statement and bring up different items for example types of curtains, colours of cushions, sizes available etc.
What I am looking for is a way to automatically resize both iFrames depending on the number of items that are displayed in the ListView in Page2.
Im not exactly familiar with iframe's (except for all the people telling me not to use them). So might i suggest using ajax instead with div's? (please correct me if im wrong in suggesting this)
You could define a scrollbar to appear instead of trying to automatically resize an iframe. What you're describing sounds messy though, and iframes there are many reasons why not to use iframes (http://blondish.net/iframes-why-not-to-use-them/). Try divs, and dynamically including the content?
In Google Reader, you can use a bookmarklet to "note" a page you're visiting. When you press the bookmarklet, a little Google form is displayed on top of the current page. In the form you can enter a description, etc. When you press Submit, the form submits itself without leaving the page, and then the form disappears. All in all, a very smooth experience.
I obviously tried to take a look at how it's done, but the most interesting parts are minified and unreadable. So...
Any ideas on how to implement something like this (on the browser side)? What issues are there? Existing blog posts describing this?
Aupajo has it right. I will, however, point you towards a bookmarklet framework I worked up for our site (www.iminta.com).
The bookmarklet itself reads as follows:
javascript:void((function(){
var e=document.createElement('script');
e.setAttribute('type','text/javascript');
e.setAttribute('src','http://www.iminta.com/javascripts/new_bookmarklet.js?noCache='+new%20Date().getTime());
document.body.appendChild(e)
})())
This just injects a new script into the document that includes this file:
http://www.iminta.com/javascripts/new_bookmarklet.js
It's important to note that the bookmarklet creates an iframe, positions it, and adds events to the document to allow the user to do things like hit escape (to close the window) or to scroll (so it stays visible). It also hides elements that don't play well with z-positioning (flash, for example). Finally, it facilitates communicating across to the javascript that is running within the iframe. In this way, you can have a close button in the iframe that tells the parent document to remove the iframe. This kind of cross-domain stuff is a bit hacky, but it's the only way (I've seen) to do it.
Not for the feint of heart; if you're not good at JavaScript, prepare to struggle.
At it's very basic level it will be using createElement to create the elements to insert into the page and appendChild or insertBefore to insert them into the page.
You can use a simple bookmarklet to add a <script> tag which loads an external JavaScript file that can push the necessary elements to the DOM and present a modal window to the user. The form is submitted via an AJAX request, it's processed server-side, and returns with success or a list of errors the user needs to correct.
So the bookmarklet would look like:
javascript:code-to-add-script-tag-and-init-the-script;
The external script would include:
The ability to add an element to the DOM
The ability to update innerHTML of that element to be the markup you want to display for the user
Handling for the AJAX form processing
The window effect can be achieved with CSS positioning.
As for one complete resource for this specific task, you'd be pretty lucky to find anything. But have a look at the smaller, individual parts and you'll find plenty of resources. Have a look around for information on modal windows, adding elements to the DOM, and AJAX processing.
