I was trying to add the id value of active element into a url. Then using a button to redirect to the url.
HTML
<div class="icon" tabindex="0" id="company">
<img src="company.png">
</div>
<button type="submit" onclick="myFunction()">jump</button>
Javascript
function myFunction(){
var x = document.activeElement.id;
location.href = "apps-online.html?page=" + x;
}
My expectations was: when I click the button, it will redirect to page
"apps-online.html?page=company"
However, the url of the new page is
"apps-online.html?page="
I was wondering why the value of x hasn't been added to the url.
Hi, everyone. For now I have understood why this problem happened. Because every time when I click the button, the button became the last active element.
So is there any way to achieve my goal?
Do check the value of x whether it is empty or not if it is empty the value of x will be passed as empty so there is no value in the url .try debugging the code or use console.log
function myFunction(){
var x = document.activeElement.id;
console.log(x);
location.href = "apps-online.html?page=" + x;
}
this gives the value of x in the console check this.
Your button does not have an id.
Give id="company" to button element.
<div class="icon" tabindex="0">
<img src="company.png">
</div>
<button id="company" type="submit" onclick="myFunction()">jump</button>
When you click on the button, the active element is button itself. I am assuming you have several divs and you need to pass the id of the highlighted element. You need to send the id to the function in some way.
Take a look below. This can be one of the many possible solutions.
HTML
<div class="icon" tabindex="0" id="company">
<img src="company.png">
</div>
<div class="icon" tabindex="1" id="something">
<img src="something.png">
</div>
<button type="submit" onclick="myFunction()">jump</button>
JS
let tabID = null;
let icons = document.getElementsByClassName('icon');
for (icon of icons)
{
icon.onclick = function()
{
tabID = document.activeElement.id;
}
}
function myFunction()
{
window.open("apps-online.html?page=" + tabID);
}

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>
I have a select field and a couple of links with images. Clicking on these images displays another link. That works flawlessly.
Now I have, in Javascript, the text of the alt attribute of the image that has to be clicked. How can I select the right one to click the one with the same alt attribute:
This is my HTML:
<div class="additionalimages">
<div class="additional-images">
<div class="row">
<div class="col">
<img src="image1.jpg" class="product-image" style="cursor: pointer" data-descr="">
</div>
<div class="col">
<img src="image2.jpg" class="product-image" style="cursor: pointer" data-descr="">
</div>
</div>
</div>
</div>
This is my Javascript to get the values of the select. Now I got for example the text "ImageOne". Now I want to select the a element with the title attribute ImageOne, so that I can fire a click event.
$(".vm-chzn-select").chosen().change(function (event) {
console.log("Select changed");
var colorText = $(".vm-chzn-select option:selected").text();
$(".additionalimages").find("a.product-image").attr("title");
});
Now the last line gives me back the value, but how can I compare so I know which one to click?
If I assume that your colorText holds the selected text value ImageOne, you should be able to simply do like this to fire a click event on the anchor with the very same title value.
$(".vm-chzn-select").chosen().change(function (event) {
console.log("Select changed");
var colorText = $(".vm-chzn-select option:selected").text();
$(".additionalimages a.product-image[title='" + colorText + "']").click();
});
You can select elements by attribute (and a variable) like this...
var altValue = "alt-tag-value";
var $img = $("img[alt='" + altValue + "']");
That will return the image (or images) that have the specified alt attribute value.
I want to know if it's possible to have the text of an "a href" element to be the value of a textbox on a button click.
$("#btn").click(function(){
$("#myLink").text($("#Coordinate1").val());
$("#myLink").prop("href", "https://www.google.com/maps/place/" + $("#Coordinate1").val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="Coordinate1">
<button id="btn">Click</button>
<a id="myLink" href="#"><!-- THIS MUST BE VALUE OF "Coordinate1" --></a>
I hope the explanation is clear enought.
Thank you.
SOLVED: Added the code on the chosen answer below. Thanks everyone for your help all the solutions given by members worked how I wanted.
You can use following code:
function setLink() {
var t = document.getElementById("Coordinate1").value;
var h = "https://www.google.com/maps/place/" + t;
var link = document.getElementById("myLink");
link.href = h; //set link url
link.innerText = h; //set link text (remove this line if you don't want it)
}
<input type="text" id="Coordinate1" oninput="setLink()">
<input type="button" value="get link" onclick="setLink()">
<div>
<a id="myLink" href="#"></a><!-- THIS MUST BE VALUE OF "Coordinate1" -->
</div>
Seem you want to do something like this.
$("#btn").click(function(){
$("#myLink").text($("#Coordinate1").val());
$("#myLink").prop("href", "https://www.google.com/maps/place/" + $("#Coordinate1").val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="btn">Click</button>
<input type="text" id="Coordinate1">
<a id="myLink" href="#"><!-- THIS MUST BE VALUE OF "Coordinate1" --></a>
Yes, you can, but you have to do it when the user click something or finishes typing the link, or some other event. Here I use a button:
$("#change").click(function() { // when the button is clicked, change the href to whatever in the input + the root, and change it's text to the value as well
var value = $("#Coordinate1").val();
$("#myLink").prop("href", "https://www.google.com/maps/place/" + value) // change the href
.text(value); // change the text content
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="Coordinate1">
<a id="myLink" href="#">
<!-- THIS MUST BE VALUE OF "Coordinate1" -->
</a>
<button id="change">Change</button>
I believe that this is what you were asking for. I took the code you already had and just placed it within the click of a button element I added to the page. Also be sure to give an actual text value inside the a tag or it won't be clickable to the user.
$("#update").click(function() {
$("#myLink").prop("href", "https://www.google.com/maps/place/" + $("#Coordinate1").val());
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="Coordinate1">
<button id="update">update</button>
<a id="myLink" href="#">
Link
<!-- THIS MUST BE VALUE OF "Coordinate1" -->
</a>
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;
}
I am using dynamic div content and toggling between them on clicks, works well but is there a way to retain the last viewed div when the user clicks forward and backward on his browser? Thanks.
<script>
$(".settings").click(function() {
var id = this.id;
if ($("." + $(this).attr('rel')).css('display') == 'none') {
$('.n_tab').hide();
$('.p_tab').hide();
($("." + $(this).attr('rel')).show());
}
});
</script>
<div class="settings" rel="n_tab">
<div class="title info_2_Title">
Notifications</div>
</div>
<div class="settings" rel="p_tab">
<div class="title info_2_Title">
Privacy</div>
</div>
<div id="MasterContainer">
<div class="n_tab" style="display: none;"> the N DIV </div>
<div class="p_tab" style="display: none;"> the P DIV </div>
</div>
Try using a library like history.js to set that up. Internally it will use the pushState API, or fall back to url fragments if the browser doesn't support that.
You could try adding an id to each tab and appending that in an object or array each time a div is selected.
Define an array history = []; outside the click event and in your click event something like
history.push($(this).id);
If you wanted to keep more detailed data you could use a json object and append to it.
Thanks for the help guys, but after fiddling ard with History.js, I still couldn't get it to work, in the end I used a cookie to store the state and then check it when the page with dynamic div loads.
$(function() {
var x = $.cookie('tab_cookie');
($(x).show());
if (x == '.m_tab') {
var btn = document.getElementById('<%= btnLoadm.ClientID %>');
if (btn) btn.click();
}
});
