I need to provide information for various clients when they log in to build a profile. I will be using HTML and Javascript for this purpose. What I would like is a concise set of instructions followed by an option to show more detailed instructions. If the client chooses to see the more detailed instructions, the field (ideally) expands to show more content.
Other ideas that achieve a similar result are also welcome, as are comments that simply point me in the right direction. Preliminary research hasn't turned up much for me; I imagine this is largely due to being a novice and not knowing what to look for. Is this a conditional visibility issue, or is that something else entirely?
Many thanks for any help.
Place the hidden content in a separate container element with its display initially set to none. Then, add an onclick handler to a link that shows the content. That handler should set the display value to block or inline. Here is one way to do it (there are many). Set up your HTML something like this:
<p>
[Instruction text here]
more ...<span class="more">
[Additional content here]</span>
</p>
Some CSS to initially hide the additional content:
.more
{
display: none;
}
Create your expandContent() function:
function expandContent(link)
{
link.nextSibling.style.display = "inline";
}

Im very new to this and have reviewed other posts similar to this question. However, I'm finding that those solutions don't work for me.
Background: I'm working in Wix's Velo platform for Javascript. (forgive me if that's not the right technical terminology here)
My goal: When my website home page loads, I want one of the text boxes on the page (#text45) to NOT be visible until 5 seconds have passed. Then, when box #text45 is visible, I want another plain box (#box2) to turn to hidden.
I have found some examples like the one below: (not all code has been pasted and I realize some elements like div1 would need to change to my specific element names)
document.getElementById("div1").style.visibility = "visible";
}
setTimeout("showIt()", 5000);
However, I get an error code: Cannot find name 'document'. Do you need to change your target library? Try changing the 'lib' compiler option to include 'dom'.
When researching this, I found out that Velo cannot access the dom and elements can only be accessed via "$w".
Would someone be kind enough to set me in the right direction on how to accomplish the "goal" above? I would really appreciate it! Thank you in advance.
Here's how you would do it. Note, that it's good practice to change the IDs of your elements to more descriptive names, but I've stuck with the names you provided in your question.
Start by setting #text45 to hidden in using the Properties & Events panel.
Then use this code (note that your page might already have an onReady. If it's there an you're not using it yet, delete all the code on the page and replace it with this):
$w.onReady( () => {
setTimeout(() => {
$w('#text45').show();
$w('#box2').hide();
}, 5000)
} );
I'm looking for a solution that will allow me to display a div when I click on a single link (which will change the way css style) with variable content (eg a sub-div with service1, service2, service3 ). This div will be displayed also propose several offers that will only display the div payment when one of these offers will be selected.
It's maybe hard to explain (i'm not english so sorry for really noob level), so maybe with this image you will "understand" a little bit more:

I confess to being a bit lost with JavaScript for this kind of thing. I know it's probably achievable, but how? :-(
Thank you for your help folks!
If you want to go the way with altering CSS with javascript, assuming you are not creating the variable content on the fly, have the divs css for display set to none.
#divID {
display = none;
}
Then set an event listener on your link to change the display style to block.
document.getElementById("linkID").addEventListener("click", function() {
document.getElementById("divID").style.display = "block";
}
Ok so I created a crude representation of what you asked without much effects. But the fiddle I created completely functions as you intended. If you click buttons on div 1 the content of div 2 gets updated. If you click anything on div2 the information is displayed in div3. Here is the example: Working Example
window.function1 = function(){
var edits = document.getElementById('2');
edits.style.background="aliceblue";
}
//SAMPLE CODE TO EDIT ANY ELEMENT BY REFERRING BY ID. CALL SUCH FUNCTION ONCLICK
Please check the example to understand it fully.
I've looked everywhere for a technique, but I failed to find much that suited my needs.
Basically, I would like to utilize JavaScript or jQuery (probably using Ajax) to grab a div that contains a word from a page on my site.
I'm not asking anyone to code this for me, I would just like to be pointed in the right direction.
For example, let's say I have this HTML page:
<div class='findfromthis'>hello guys</div>
<div class='findfromthis'>goodbye guys</div>
<div class='findfromthis'>goodbye people</div>
I would like to display all the divs that contain the word "guys" in them.
Thank you so much in advance!!
JQuery has a contains selector that will find all elements containing specific text. Something along the lines of $("div:contains('guys')") should do the trick. Then you can use .each or .show etc to work with the selected elements.
See http://api.jquery.com/contains-selector/ for more detail.
EDIT :
The following code was deemed useful by the OP. It'll select all divs with class "findfromthis" which don't contain the phrase "guys", and remove them from the DOM:
$("div.findfromthis:not(:contains('guys'))").remove();
Give your div a class, say '.myDiv' and then via jQuery:
$('.myDiv').doSomething...
I'm not entirely sure how AJAX would play into this, but to point you in the right direction:
http://api.jquery.com/jQuery.ajax/
Your edit is an entirely different question. But you'd do the same to get the divs. In this case, you'd use 'each':
$('.findfromthis').each(function(){
// for each div you can now grab the text it contains:
DivText = $(this).text();
// now you could use a variety of different JS seach techniques to find
// your content. But one example to search for a word or word fragment would be:
if (DivText.indexOf("guys") !== -1)){
// then this div has the word 'guys' in its text somewhere
}
})
If the search term is more complex (like not wanting to find fragments) then you may want to use REGEX for the search part instead.
Again, though, not sure where AJAX would fit into this. This all can happen client-side.
I have a site that is in English and Spanish, and in each page of the site there is a link that leads to the Spanish version of that specific page, so if the user were on the "home.php" page, it would look like this:
<div id="language">
<ul class="language">
<li class="english"></li>
<li class="divider"></li>
<li class="spanish"></li>
</ul>
</div>
What I would like to do is leave the href and the class in the <a> tags in the HTML blank and assign a class and an href URL to the <a> depending on the page the user is on, that way I could, for example, just add that language div to an external file, and use an <include> to attach it to each page. To accomplish this I'm using the following code:
$('ul.menubar a').each(function(){
if(location.href.match('home.php')){
$('ul.language li.english a').addClass('active');
$('ul.language li.english a').append(function() {
$(this).attr('onclick', 'return false;');
});
$('ul.language li.spanish a').addClass('notactive');
$('ul.language a[href!="home.php"]').append(function() {
$(this).attr('href', 'inicio.php');
});
}
}
The problem is that the English version of the site has 4 links in the navigation bar (home.php, services.php, aboutus.php, contact.php), and the Spanish version likewise (with the corresponding translation of the URL names). I think that having to repeat that code 8 times (1 for each link, 4 links in each language) would be excessive and would actually add more code than simply adding the class and href url in the HTML. The point of using JS would be to simplify things.
So I basically would like to know if anyone can think of a better way to do this, that wouldn't require that much code. I'm trying to avoid having to, in the event that I'd need to change something, have to edit each different page. Also, I would like to know if this is the best way to achieve want I want to do using JavaScript.
HTML is best suited for managing content. CSS is best suited for presenting that content, and JavaScript is best suited for determining how that content behaves. Instead of trying to inject links and control the HTML from JavaScript; instead, leave the content where it belongs, inside the HTML, and use JavaScript to define one or two event-handlers to take action based on the class values on the hyperlinks themselves.
You already have a class on your English hyperlinks, and a separate class on your Spanish hyperlinks, so you can use this to your advantage.
Writing the Click Handlers:
Since toggling your "Language switch" most likely causes a boolean value to be set, you can use two click handlers to target all of your English links and all of your Spanish links, and then control the behavior based on the value of that switch at the time the links are clicked.
// handler for all English links
$('li.english a').click(function(event) {
event.preventDefault();
if(/* Switch is english */) {
window.location = $(this).attr("href");
}
});
// handler for all Spanish links
$('li.spanish a').click(function() {
event.preventDefault();
if(/* Switch is SPANISH */) {
window.location = $(this).attr("href");
}
});
Note that when a link is clicked, we first check the switch. Depending on it's value, we either redirect to that hyperlink, or simply prevent the default behavior -- going to a new page -- from completing.
Handling the Presentation:
Now, your other problem is going to be that, assuming your Spanish site and your English site are one in the same, you'll now see 8 hyperlinks in total. Again, this is where your switch can come in handy.
// single handedly hide or display the relevant content, based on the switch
function switchToEnglish() {
$('.english').show();
$('.spanish').hide();
}
function switchToSpanish() {
$('.spanish').show();
$('.english').hide();
}
Now, I don't know what else is contained in your switch function, but the general idea here is that we don't need to modify the content. We just need to show and hide the content. You'd need to integrate this concept into your existing switch function, if you don't already have something like this in place.
There are several advantages in this approach:
Your Web designers will still see href's in the HTML and can read and understand the HTML without needing your help or needing to go and look at JavaScript code. Not only will they see familiar patterns that they're used to seeing, but you'll likely have a better working relationship with them.
Search engines spidering your site will be able to read the links and follow them.
Browsers without JavaScript will be able to process the links. Some people seem to care about this. I don't. But it's worth mentioning anyway.
In summary, you're right about it being easier to manage in HTML. By using this technique, you can eliminate the repetition in the code that you're rightfully concerned about, and also move the content back to the HTML, as your gut is telling you is the correct thing to do. Not only will your code be more readable, but you'll get better SEO results as well.
I have a list being displayed on a JSP. On mouse hover on any of the value i need to show a description corresponding that value. Need to show description not as an alert and also cannot make the values as hyperlink.
eg.
suppose the value is ABC so on mouse hover should show AppleBoyCat.
need to use onmouseover. let me know how to do it..
What do you want to do? If you just want to show a tooltip, you can set the title attribute of any element and it will be displayed as a tooltip.
Also, the abbr tag can be used as tooltips too:
<abbr title="test">stuff</abbr>
You can go about it in two ways:
1 - a hidden dom object (a div for instance) which reveals itself when you roll over whatever
or
2 - you can rewrite the html of the particular element you're mousing over.
You can load this data in when you load everything else (either as Javascript objects, or as markup, though that's much bulkier) or you can asynchronously load the description data from a service when you mouse over (though you'll have more lag).
jQuery is a quick and dirty way to achieve this (more quick than dirty), but straight JS or pretty much any other JS library will do as well.
Perhaps not the cleanest solution but something like this:
<a class='hover' rel='tooltip'>Link</a>
//Some hidden div, putting css inline just for example
<div id='tooltip' style='display:none;'>Content</div>
$(function() {
$('.hover').mouseover(function() {
var tooltip = $(this).attr('rel');
$('#' + tooltip).fadeIn();
});
});
And offcourse add a callback hiding it again. It just takes the value from rel of the link and use as an id for the div to show.
This is a quick and dirty solution, can be made alot smoother if you just work with it a little;)
There also alot of plugins out there allowing the same functionality in a cleaner fashion.
*Edit: Just noticed you added a comment on another post that you can't use jQuery.. shouldn't tag a post with something you're not intending to use.
As TJHeuvel already said, you can simply use the title attribute.
Best approach is to build the list with both the value and title attribute from within JSP, if not possible for some reason, you can build client side array of each value and its corresponding description then using JavaScript dynamically assign the title on mouseover.
Show us some more code to get more/better help.
For simple tooltips, the title attribute is most effective, as pointed out by TJHeuvel
If you need more advanced tooltips with HTML and CSS formatting, I'd suggest you use an external library.
One that works nicely without jQuery ist wz_tooltip download here, documentation here
When included correctly, you can add tooltips by calling the functions Tip() and UnTip() as follows:
