I new in Javascript. I'm working on my Django project and I want to add some buttons like img button. Here is example:
So when user will click img button in textarea will be added this text :
<img src="[YOUR IMAGE]">
Thanks for help.
If i understand your question correctly you have to call a function in javascript to write to your specified element and on your image you use a onclick.
something like:
onclick="document.location=this.id+'.html'
Sample:
$(function(){
var $display = $('#display');
$display.val(0);
$(document).on('click', 'button.number', function(){
if($display.val() != 0) {
$display.val($display.val() + $(this).val());
} else {
$display.val($(this).val());
}
});
});

This was probably already answered here: Using jQuery to click the button and display the value of the button

You need more than an image if you're not aware of it already. I suggest using Glyphicons for that purpose, will simplify everything and will be more lightweight.
Say we use the fontawesome glyphs.
Create a bar above text area where you'll hold your controls,
<section>
<i id="control-bold" class="fa fa-bold" aria-hidden="true"></i>
<i id="control-italic" class="fa fa-italic" aria-hidden="true"></i>
</section>
<textarea id="textarea"></textarea>
For simplicity I used ids on the button control elements, and will use JQuery to listen to click events to make it even more simple.
$("#control-bold").click(function(){
// Bold was clicked append {bold} to text area with whatever..
$("#textarea").append("{bold}");
});
$("#control-italic").click(function(){
// Italic was clicked append {bold} to text area with whatever..
$("#textarea").append("{bold}");
});
Note this is a simple & basic example to get you started. Glyphicons and JQuery are only my suggestion for this question.
If you are looking for a way to change your button style, I will suggest you to use CSS instead of <img> HTML tag.
a CSS class/id for unselected button with the default background-image
a CSS class/id which override background-image or selected buttons
And you will add/remove classes using javascript element.classList.add('.selected') or element.classList.remove('.selected')

I'm really new to Jquery, JavaScript, Html
In our WordPress shop, there's an alert message that only appears if the user is below his set "Order Minimum Total".
i've looked in the source code and i saw that when the message is not visible on the page, the DIV "wcc-validation" has "hidden" added in its Class.
That's a copy of the code <div class="wcc-validation hidden" id="wcc-validation">
What we need is for our SideCart button to be set "display:none", whenever wcc-validation message appears on the screen (doesn't have the Class attribute of "hidden")
Whenever wcc-validation message disappears and gets the Class Attribute "Hidden" - make the SideCart button appear on the screen. (display:block?)
I've researched a bit and realized this cant be done with CSS,
I dont mind adding JS/Jquery snippets to make it work, but couldn't figure out how to spot a DIV that has a "hidden" Class attribute in it - and apply the show/hide on the sidecart button from that.
thanks a lot.

you can check for the class 'hidden' if it is available for the 'wcc-validation', Like the following snippet:
jQuery(document).ready(function($){
if($('#wcc-validation').hasClass('hidden')){
$('.to_hide').hide();
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="wcc-validation hidden" id="wcc-validation">
<div class="to_hide">to hide based on hidden class</div>
You can check the value like this.
function checkValue(){
let ele = document.getElementById('wcc-validation')
if (ele.value) {
do what you want. change css, style etc
}
}
I've been searching the web for some tips regarding how to make your own numpad, created with html code, to act as a numpad would on the computer.
I have this numpad on my website that would give an input to a textfield in the same div. I've given a value to each button and now I guess I would have to create something more so that the numbers will add to my text field.
I'm really a beginner with programming so maybe this is really easy. Thanks for the help!
You could do it, alternatively, with jQuery. jQuery is better IMHO if you need a simple easy solution (jQuery is generally easier and faster).
HTML:
<div id="myDiv"> </div> //the div to which we add text
<div id="buttonContainer"> //this is the div containing the numbers (the numpad)
<button value="one"> one </button>
<button value="two"> two </button>
</div>
jQuery:
$("#buttonContainer button").click(function() {
$("#myDiv").append($(this).val());
});
http://jsfiddle.net/DLzUU/1/
What this does is: when you click any button inside the div with id of 'buttonContainer', it adds its value to the div with the id of "myDiv".
On the Javascript subject, if you want a VERY good guide: http://javascript.info/
what you need is to learn javascript. With javascript you will be able to write code to do this.
<script>
function AddValueToTextField(val)
{
document.getElementByID( <textfiled ID> ).value += val;
}
</script>
<button onClick="AddValueToTextField(this.value)"></button>
this is only very basic but it is a rough idea of what is needed, the button is set to call the function "AddValueToTextField" when it is clicked. When the function is called the value of the button is sent along with it. Inside the function it gets a handle on the textfield and adds the value of the button to whatever was already there, I'd suggest looking at:
http://www.w3schools.com/js/
as a place to start learning javascript.
you can try http://keith-wood.name/keypad.htmlkeypad example, this is an awesome example
$(document).ready(function(){
var selected;
$(".admin_loginid input").focus(function(){
selected = $(this);
});
$(".loginbtn").click(function(){
selected.val(selected.val() + $(this).val());
});
});
Solved it that way and it works really well, thanks for the help! Now my selected input box takes the input from the numpad that i've created.
I have following HTML and would like to disable the link using javascript.
<a style="white-space: nowrap;" onclick="return InstallWebApp(true);" id="uc_ii_lnkInstall" href="javascript:__doPostBack('uc_ii$lnkInstall','')">
<img style="border-width: 0pt; margin-right: 3px;" id="uc_ii_lnkInstallImg" alt="Install" title="Install" src="/CortexDotNet/pics/buttons/install_g.gif">
Install
</a>
The JavaScript I am using are :
document.getElementById("uc_ii_lnkInstall").disabled = true;
However , it does not work , I could still click this this link after I have disabled the link using the above javascript.I look at the html , it does not seem to have the disable attribute in the a tag.Can anyone help me to explain this please?
document.getElementById("uc_ii_lnkInstall").onclick = function() { return false; };
The return value of false in the old-style event handler prevents the default action (i.e. loading the javascript: URL).
If you want to gray out the image link, you would also need to swap out the image's src URL with one pointing to a grayed-out version of the icon and change the text's color using .style.color = "gray";.
I don't think the 'disable' attribute will work on links, it work mostly on form elements such as inputs, textarea, button, etc.
But as #idealmachine said normal links <a> can be disabled by returning false 'return false' in javascript/jquery.
For example:
let link_example = document.querySelector("#top-content .view-content a");
link_example.removeAttribute("href");
Here is a short and easy way to disable a link.
<a href="javascript:void(0)" >My link is disabled</a>
I'm applying a style to a certain phrase on our website over and over again. Is there a way to search the page for instances of that phrase and apply that style automatically?
Example:
<div>
This is what you get from <span class="comp">Company Name</span>.
We do all kinds of things here at <span class="comp">Company Name</span>.
</div>
You could take a look at these questions:
Highlight a word with jQuery
How to highlight certain words with jQuery
Both of the top answers point to the highlight plugin for jQuery.
sure...
http://docs.jquery.com/Selectors/contains#text
$("div:contains('Conpany Name')").css("text-decoration", "underline");
var body = document.getElementByTagName("body")[0].innerHTML;
body.replace(/Company Name/g, '<span class="comp">Company Name</span>');
document.getElementByTagName("body")[0].innerHTML = body;
The above should get everything in the body and replace it with your span and that doesnt need jQuery.
OK, I'm designing a site and thought I'd stick some jQuery in as I really need so js experience.
Page with my problem is here: http://new.focalpix.co.uk/moreinfo.php
JS in question is:
$(document).ready(function(){
$(".answer").css("display","none");
$("#maincontent a.animate").click(function() {
$("#maincontent .answer").slideUp('slow');
var id = $(this).attr('href');
$(id).slideDown('slow');
return false;
});
});
This works fine, but if you click on a link where the answer has already slid down, then it slides up, then back down again.
I'm not sure on the cleanest way to stop this happening - any ideas?
You should be using the .slideToggle() effect.
$(document).ready(function() {
$(".answer").css("display","none");
$("#maincontent a.animate").click(function() {
$("#maincontent .answer").slideToggle('slow');
});
});
First, I'd suggest the following structure for your faq's:
<div id="faq">
<div class="qa" id="faq_greenandflies">
<span class="q">What is green and flies</span>
<div class="a">
Super Pickle!
</div>
</div>
<div class="qa" id="faq_redandbadforteeth">
<span class="q">What is Red and bad for your teeth</span>
<div class="a">
a Brick
</div>
</div>
<!--
More FAQ's here
-->
</div>
and then defining your jQuery as follows:
<script type="text/javascript">
$(function(){
// hide all answers
$('div#faq .qa .a').hide();
// bind a click event to all questions
$('div#faq .qa .q a').bind(
'click',
function(e){
// roll up all of the other answers (See Ex.1)
$(this).parents('.qa').siblings().children('.a').slideUp();
// reveal this answer (See Ex.2)
$(this).parents('.qa').children('.a').slideDown();
// return true to keep any other click events
return true;
});
// check location.hash to see if we need to expand one (direct link)
$(location.hash).find('.q a').click();
});
</script>
Explanation:
(Ex.1)
this is the link that was clicked
get the element that contains this and has a class of 'qa' (the box that contains both question and answer)
select all of its siblings. (we now have all qa's as a jQ object)
hide the answers
(Ex.2)
this is the line or link that was clicked
get the element that contains this and has a class of 'qa' (the box that contains both question and answer)
reveal the answer
A working demo is here.
This does several things for you:
If a user deep-links to an answer, the answer is automatically revealed
If a user clicks on one answer, all other answers are hidden
You can give your divs proper ids, so which helps search engine optimization of links to individual answers
Use slideToggle() like Soviut said, but just as a tip -- you can declare the display property in the actual CSS file instead of declaring it inside the javascript. jQuery will pick up on the fact that it is hidden in the stylesheet and still perform the appropriate slide function.
You can also use $(".answer").hide();
Instead of setting the display CSS property. Just thought I would let you know.
try using the one method, something like:
$(selector).one('effect', 'data for effect', callback function);
it makes sure an effect only happens once per element.
