Using js onclick on one button to inject link into another

I have two buttons, both without links, and want to add a link to one when the other is clicked. How can I make one button with an onclick give a link attribute to something else on the page? If not a button, maybe a div?
The following is my current code:
<div class="container">
<div class="jumbotron" style="background-color:#000000 !important;">
<img id="myImage" src="images/closed.png" style="width:100%">
<p id="texthere"></p>
<div class="container">
<div class="row">
<div class="col">
<button onclick="document.getElementById('myImage').src='images/open.png'" class="btn btn-primary active btn-block">Open Eyes</button>
</div>
<div class="col">
<button onclick="document.getElementById('myImage').src='images/closed.png'"class="btn btn-primary active btn-block">Close eyes</button>
</div>
</div>
</div>
Thank you in advance for your help.
*Edited to clarify and pose as a question.

I think you may be confused about how HTML links work. HTML has the a tag for elements that a user can click to go to a different URL. The (worse) alternative is to use an onclick handler to redirect the user by setting the value of window.location.
To make a button that creates a link on the page, put a script tag at the bottom of the body that attaches a listener to a button that, when called, places a link on the page.
<script type="text/javascript">
var button = document.getElementById('my-button'); // This button has to exist.
button.addEventListener('click', function() {
var link = document.createElement('a');
link.href = 'google.com'; // Or wherever you want the link to point.
document.body.appendChild(link);
});
</script>

While there are many ways to do what you want, without knowing what programming skills you have and what you want to see on the screen, perhaps this sort of structure would help you. Replace your current onclick handlers on the BUTTONs:
<button id="open" class="btn btn-primary active btn-block">Open Eyes</button>
<button id="close" class="btn btn-primary active btn-block">Close eyes</button>
<script>
document.getElementById("open").addEventListener("click", function() {
changeState('open');
});
document.getElementById("close").addEventListener("click", function() {
changeState('closed')
});
function changeState(state) {
document.getElementById("myImage").src = 'images/' + state + '.png';
var new_para = document.createElement("p");
var new_link = document.createElement("a");
new_link.setAttribute("href", "https://www.google.com/search?" + state);
var new_link_text = document.createTextNode("Search for '" + state + "'");
new_link.appendChild(new_link_text);
new_para.appendChild(new_link);
document.body.appendChild(new_para);
}
</script>

Swap div and contents on click

Been trying to swap 2 divs. When the button is clicked #profeditclick1, #profswitch1 should swap with #hideedit1. At the moment when the button is clicked all the divs just disappear. Thank for your help or guidance.
HTML:
<div class="cart_verwrap" >
<div class="cart_verbill" *id="profswitch1">
<div class="btn blue cartprof-btn l-btn txt_fff s16" id="profeditclick1">Edit</div>
</div>
<!-- hidden edit profile in css it set to display:none-->
<div class="cart_verbill" id="hideedit1">
</div>
jQuery:
$("#profeditclick1").click(function(e) {
e.preventDefault();
var content = $(this).html();
$('#profswitch1').replaceWith('<div id="hideedit1">' + content + '</div>');
});
UPDATE
Next attempt although doesnt seem to work. i have taken of the display:none and tried to hide it:
$("#hideedit1").hide();
$("#profeditclick1").click(function(e) {
e.preventDefault();
var content = $(this).html();
$('#profswitch1').replaceWith('<div id="hideedit1">' + content + '</div>');
$("#hideedit1").show();
});

I think this may help you. I have added some modification in your HTML.
Please check it and change it as you need.
jQuery('#hideedit1').hide();
jQuery('#profeditclick1').click(function(){
jQuery(this).hide();
jQuery('#hideedit1').show();
});
jQuery('#hideedit1 #save_edit').click(function(){
jQuery('#hideedit1').hide();
jQuery('#profeditclick1').show();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div class="cart_verwrap" >
<div class="cart_verbill">
<div class="btn blue cartprof-btn l-btn txt_fff s16" id="profeditclick1">Edit</div>
</div>
<!-- hidden edit profile in css it set to display:none-->
<div class="cart_verbill" id="hideedit1"> EDIT PROFILE CONTENT <button id="save_edit">Save</button> </div>
</div>

Find sibling with Javascript and Hammer.js

I have made a simple system which detects double taps. I want to show a heart icon when someone double taps on an image, just like on Instagram.
This is what my code looks right now:
var elements = document.getElementsByClassName('snap_img');
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
// Some javascript to show the heart icon
});
});
This is what the HTML looks like:
<div class="snap_item">
<div class="snap_item_following_info">
<img class="snap_item_following_img" src="res/stat/img/user/profile/small/1.fw.png" alt="#JohnDoe" />
<a class="snap_item_following_name" href="#">#JohnDoe</a>
<div class="snap_too">
</div>
</div>
<img class="snap_img" src="res/stat/img/user/snap/43/2.fw.png" alt="#ErolSimsir" />
<div class="like_heart"></div>
<div class="snap_info">
<div class="snap_text">
LA is the shit...
<a class="snap_text_hashtah" href="#">#LA_city_trip</a>
</div>
<div class="snap_sub_info">
<span class="snap_time">56 minutes ago</span>
<div class="like inactive_like">
<div class="like_icon"></div>
<div class="like_no_active">5477</div>
</div>
</div>
</div>
</div>
So when the element 'snap_img' is double tapped, I need to get the element 'like_heart' which is one line below the snap_img element. How do I get that sibling element and fade it in with JQuery?

Like this
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
$(element).next().text('♥').hide().fadeIn();
});
});
P.S. I've added that heart text, since the sibling was empty.

On the event handler, i would do $(element).parent().find('.like_heart').fadeIn(); So the code is not dependant on the element ordering.
(To clarify to selector: take the parent element which is the div.snap_item and find an element with class like-heart inside it)

Want to make inactive hyperlink

I have problem in hide and show the div element.
In this scenario when user click on the year the respect content is shown.
Problem I want to inactive hyperlinking on respective year when it is opened.
The script and html is below;
for this I have tried .preventDefault(). but not got any success:
<script type="text/javascript" >
$(document).ready(function() {
$("div.new:gt(0)").hide();// to hide all div except for the first one
$("div[name=arrow]:eq(0)").hide();
// $("div.nhide:gt(0)").hide();
// $("a[name=new]").hide();
$("a[name=new]").hide();
$('#content a').click(function(selected) {
var getID = $(this).attr("id");
var value= $(this).html();
if( value == '<< Hide')
{
// $("#" + getID + "arrow").hide();
$("a[name=new]").hide();
$("#" + getID + "_info" ).slideUp('slow');
$("div[name=arrow]").show();
$("div.new").hide();
$(this).hide();
// var getOldId=getID;
// $("#" + getID ).html('<< Hide').hide();
}
if($("a[name=show]"))
{
// $("div.new:eq(0)").slideUp()
$("div.new").hide();
$("div[name=arrow]").show();
$("a[name=new]").hide();
$("#news" + getID + "arrow").hide();
$("#news" + getID + "_info" ).slideDown();
$("#news" + getID ).html('<< Hide').slideDown();
}
});
});
</script>
The html code is below:
<div id="content">
<div class="news_year">
<a href="#" name="show" id="2012">
<div style="float:left;" name="year" id="news2012year">**2012** </div>
<div style="float:left;" name="arrow" id="news2012arrow">>></div>
</a>
</div>
<div class="new" id="news2012_info">
<div class="news">
<div class="news_left">News for 2012</div>
</div>
<div class="nhide" ><< Hide </div>
</div>
<div id="content">
<div class="news_year">
<a href="#" name="show" id="2011">
<div style="float:left;" name="year" id="news2012year">2012 </div>
<div style="float:left;" name="arrow" id="news2012arrow">>></div>
</a>
</div>
<div class="new" id="news2011_info">
<div class="news">
<div class="news_left">News for 2011</div>
</div>
<div class="nhide" ><< Hide </div>
</div>
Fiddle

if i am understanding your problem,
event.preventDefault(); not works with all browser so if you are using other browser like IE
then use event.returnValue = false; instead of that.so you can detect your browser using javascript as
var appname = window.navigator.appName;

This is what I'm currently using in my projects to "disable" an anchor tag
Disabling the anchor:
Remove href attribute
Change the opacity for added effect
<script>
$(document).ready(function(){
$("a").click(function () {
$(this).fadeTo("fast", .5).removeAttr("href");
});
});
</script>
Enabling the anchor:
$(document).ready(function(){
$("a").click(function () {
$(this).fadeIn("fast").attr("href", "http://whatever.com/wherever.html");
});
});
Original code can be found here

Add a class called 'shown' to your wrapper element when expanding your element and remove it when hiding it. Use .hasClass('shown') to ensure the inappropriate conditional is never executed.

Surround the code inside of the click function with an if statement checking to see if a variable is true or false. If it is false, it won't run the code, meaning the link is effectively inactive. Try this..
var isActive = true;
if (isActive) {
// Your code here
}
// The place where you want to de-activate the link
isActive = false;
You could also consider changing the link colour to a grey to signify that it is inactive.
Edit
Just realised that you want to have multiple links being disabled.. the code above will disable all of them. Try the code below (put the if around the code in the click function)
if(!$(this).hasClass("disabled")) {
// Your code here
}
// The place where you want to de-activate the link
$("#linkid").addClass("disabled");
// To re-enable a link
$("#linkid").removeClass("disabled");
// You can even toggle the link from disabled and non-disabled!
$("#linkid").toggleClass("disabled");
Then in your CSS you could have a declaration like this:
.disabled:link {
color:#999;
}

how to hide/remove all text in-between two elements?

lets say i have this lump of HTML:
<div class="container">
<span class="title">Heading 1</span>
This is a description..<br />
This is the second line..
<div class="image"><img src="image.jpg" /></div>
</div>
What i want to do using jQuery/JavaScript is hide/remove all text and elements between <span class="title"> and <div class="image">.
I've looked all over and found pretty much nothing. Any ideas on how i could do this?

How about something like this? http://jsfiddle.net/ZW8q2/1
var foo = $('.container').children(':not(br)');
$('.container').html('').html(foo);

You could try:
var str = $('.container .title').text() + $('.container .image').html();
$('.container').html(str);
JS Fiddle.

Try this:
Place a tag around what you want to hide, give div an ID name. So in the end your will look like:
<div id = "hideMe" style ="display:block">...Your Content...</div>
Use this javascript:
function hide()
{
document.getElementById('hideMe').style.display = "none";
return;
}
Have the Javascript function called whenever you want to hide the stuff between the div from a button (or other control) like this:
<input type= "submit" onclick ="hide()">
