This is my web structure. In which all link contents are opened in iFrame when link is clicked.
Say I have clicked on 1st link (not Home page) , it gets open in iFrame,contents are displayed properly,all ok. But as I press refresh button expected is shlould load same page whose link I have clicked,but instead of that it loads Home page.
How should I be on same page after refresh also?
I'm using php for server side scripting. Thanks!
Edit:
I tried to store visited page name in session variable and then while loading Home page I check like
$_Session['visited']='/pages/neworder.html';
if(isset($_Session['visited']))
{
echo "<script>window.location.href=</script>".$_Session['visited'];
}
But didnt work!
I think the simplest way is with Jquery. If you make your website use anchors, for example
http://yoursite.com/#page-example
example
When you refresh the page, you will still be accessing this anchor. With jquery you can get this value and do some stuff based on that. So!
var hash = $(this).attr('href').split('#')[1];
This will get that # value, you can compare that in javascript then, or use a switch to determine what to do or simulate the page change.
Server side: Link sends GET request to the page and the src of the iFrame is set by the server.
-OR-
Client side: Add onclick function on the links which changes the src atribute for example with the following code:
document.getElementById('Iframe').src="new link";
-OR-
<iframe src="startin_link" name="iframe_a"></iframe>
<p>link</p>
Pure html.
EDIT: If you want to stay in the page... I suggest you use the first option. Example:
<a href='?page=1'>Some link</a>
then on server side:
if(!is_null($_GET['page'])){
$iframeLink=arrayOfLinks[$_GET['page']];
}else{
$iframeLink="Starting Link";
}
and the iFrame should look like this:
<iframe src='<?php echo $iframeLink; ?>'></iframe>

It was hard to encapsulate my question in the title.
I've rewritten a personal web page that made extensive use of javascript. I'm simplifying matters (or so I hope).
I use a home automation server that has a REST interface. I can send commands such as 'http://192.168.0.111/rest/nodes/7%2032%20CD%201/cmd/DON to turn on a light. I'm putting links on my simplified web page using an href tag. The problem is that it opens the rest interface page and displays the XML result. I'd like to avoid having that page show up. ie when you click on the link it 'goes' to the link but doesn't change the page.
This seems like it should/would not be possible but I've learned not to underestimate the community.
Any thoughts?
You can use the fetch function if your browser is modern enough:
document.querySelector(lightSelector).addEventListener('click', e => {
e.preventDefault(); // prevent the REST page from opening
fetch(lightURL).then // put promises here
})
The variables lightSelector and lightURL are expected to be defined somewhere.
The code listens for clicks on the link, and when one comes, we prevent the REST page from opening (your intention) then we send a request to your light URL with fetch. You can add some promises to deal with the response (e.g. print "light on" or "light off" for example) using then but that's another matter.
If you make the "link" a button, you can get rid of e.preventDefault(); which is the part preventing the REST page from opening.
I'm trying to create a link on my page that goes to a page with the right id. The page where the link is is at: http://localhost:3000/quotes/9942/marketingScheduleShell. Once the link is clicked the page should redirect to http://localhost:3000/quotes/9942/.
Something along these lines is how I want this to work but when I try the code below it just takes me to the /quotes/ page.
<a href='http://localhost:3000/quotes/' + #quote.id>Show</a>
How can I use the id of the quote object I click on to go to the correct page for that object?
The only think you need is a link_to method
link_to('Show', quote_path(#quote))
Also reading some guides would save you a lot of time: http://guides.rubyonrails.org/
I am at a bit of loss of knowledge and honestly don't know what to search for. What I need to be able to do is determine what content to show on a webpage that way when I refresh it will not reset everything. For example, if someone clicks on the messages tab I want the browser to know when it refreshes, that is the tab to stay on. I believe this is done through url encoding but I am not sure. Any help would be AWESOME! Thanks fellow coders.
MORE INFO: I have 2 buttons on a page. One is named "home" and when I click it I want the content of the home page to appear in a box named "info-main". I am doing this with ajax requests. When I click on "edit profile", I want the content in div id "info-main" to be replaced with the edit profile information that is retrieved via ajax as well. I need to figure out how if someone refreshes the page... I want it to stay showing the edit profile information rather then going back to the default of "home" content.
MORE INFO(AGAIN)
I just had a great idea. When the page refreshes, I want it to load specific ajax code based on what the url encode is.
For example.... if the url is:
http://www.exampleurl.com/index.php?info=status-load
I want the browser to execute the ajax I have for retrieving status's.
OR
If the url is:
http://www.exampleurl.com/index.php?info=edit-prof
I want it to load the ajax code I have for retrieving profile edit info.
I really hope this helps. :/
The way I do it is I place a # before the link i.e. href="#messages"
Then I link a .js with this code.
$(function () {
var hash = location.hash
, hashPieces = hash.split('?')
, activeTab = $('[href=' + hashPieces[0] + ']');
activeTab && activeTab.tab('show');
});
I hope this helps
For referring an element on your page, you use a link with a hashtag.
For example, if you have a layout like this:
<div class="top-nav">
Home
Edit Profile
</div>
And you have a password edit form on your editProfile page, you can like to it like this:
Edit Profile
if you have a <form id="passwordChange"> on your editProfile.

I'd like my web page to have a "Show Source" link that will show the source of my HTML.
I'm also wondering if there's something I could append to the URL of my page that'll just show the source as opposed to rendering the page. Like this...
http://www.example.com/mypage.html#show_source
If you are okay with a link that opens source, you could use the following javascript:
if you are using FF:
window.location = "view-source:" + window.location.href;
and with IE:
var popup=window.open();
popup.document.open('text/plain').write(document.documentElement.outerHTML)
If all you need is code between the body tags - then you could do the following:
document.body.innerHTML
Can you provide a bit more information on the application?
"View Source Button" could be a solution, but if you need a direct link you need to change the Content-Type Header of your file to "plain/text".
If your page could be, for example, a PHP script, it would be:
<?php if($_GET["viewsource"]=="yes") header("Content-Type: plain/text"); ?>
and you can open link by appending ?viewsource=yes to your URL.
Remember, it works only "server side".
When I add a HTML link to a specific part of the page:
test
I noticed that it changes the URL at the address bar. Although I have come across websites where they link that way without the address bar being updated. How is this possible?
EDIT: It might be an AJAX solution were they make it work without URL change, as if I remember correctly, the page didn't reload, it went directly to the destination...
You may wish to look at the jquery plugin, scrollTo.
http://jquery.com
And a couple of links for scrollTo
http://demos.flesler.com/jquery/scrollTo/
http://flesler.blogspot.com/2007/10/jqueryscrollto.html
You can do something like this:
The HTML
click me to scroll
<div class="gap">a big gap</div>
<h1 id="scrollToMe">I should scroll to here without a # in the URL</h1>
The javascript (jquery and the scrollto plugin)
$(document).ready(function() {
$(".scrollLink").click(function(e) {
$.scrollTo($(this).attr("href"));
e.preventDefault();
});
});
What the javascript does, is when ever a link is clicked that has the class ".scrollLink", scroll the page down to the element that has the same ID, as the href for the particular link clicked. Then the e.preventDefault() stops it working like the normal hash link and stops it appearing in the URL bar.
Here is a working example for you: http://jsfiddle.net/alexkey/c3jsY/7/
And a version not in a frameset, so you can see that the URL doesn't change:
http://fiddle.jshell.net/alexkey/c3jsY/7/show/light/
This approach has a couple of good points
Simply apply the scrollLink class to links you want to stop the hash appearing (nice and easy)
It uses the normal href, which also means the links will still work even if javascript is disabled - good for accessibility and probably search engine optimisation to.
It's possible to use javascript to intercept the click event, perform your own custom logic, then cancel the navigation event so the URL never changes
Maybe you can try something like: window.scroll(0,150);
instead of "(0,150)" put the cooridnate of your target.
You'll have to experiment with the number (shown here as 200) to get the window to align properly.
test
You could use inline the next code:
link text
<div id="bookmark">Jump to here</div>
