I have a button inside the anchor tag(defined it using class).
<a id="moreButton" class="contactButtonSmall" style="position:absolute; left:225px; top:165px; FONT-WEIGHT:normal; FONT-SIZE:11pt;" onclick="doSomething();">More</a>
Now I want to disable it.So I have used the following code to disable the anchor tag.
moreButton.disabled = true;
The anchor tag is not working after disabling it , but the button of anchor still looks as if it is not disabled i.e. not grayed out. Is there any way to disable the button? Please let me know if you need any additional information.
The best way to disable an anchor tag is to give it the correct pointer-events property. Here's a simple example how to disable the anchor tag with one simple CSS line:
a {
pointer-events: none;
}
I am a disabled anchor tag
As others have said, inline CSS is bad practice so you should export your style code to a separate CSS file, as so:
.contactButtonSmall {
position:absolute;
left:225px;
top:165px;
font-weight:normal;
font-size:11pt;
}
Then you can use the :disabled selector to change the appearance of the button when it is disabled:
.contactButtonSmall:disabled {
/* Styling for disabled button */
}
I have used button along with the style attributes
background-color: Transparent;
border: none;
instead of anchor tag to fix the issue. The style attributes helped to remove the grayed out area of the original html button and to keep my own image for the button.
example code is given below:
<button> id="moreButton" class="contactButtonSmall" style="position:absolute; left:225px; top:165px; FONT-WEIGHT:normal; FONT-SIZE:11pt; background-color: Transparent;border: none;" onclick="doSomething();">More</button>
In CSS file:
.contactButtonSmall {
position:relative;
display: block; /* 'convert' <a> to <div> */
width: 60px;
max-height: 20px;
padding-top: 2px;
padding-bottom: 2px;
background-position: center top;
background-repeat: no-repeat;
background-image: url(../contactImages/blankSmallButton.gif);
text-decoration: none;
text-align: center;
cursor:pointer;
background-color: Transparent;
border: none;
}
You can use a mixture of CSS and JS to accomplish this:
HTML:
<a href="/" id="myLink">
click me!
</a>
CSS:
#myLink {
background: red
}
a#myLink.disabledLink {
background: grey;
cursor: not-allowed;
}
JS:
document.getElementById("myLink").onclick = function(e)
{
e.preventDefault();
this.className += " disabledLink";
}
jsfiddle here
this on click prevents the default action of the anchor tag and assigns it a class. The class has css that makes the cursor show the now-allowed icon as well as changing background colour to grey.
i am trying to implement accordion.
My accordion should expand on mouse hover on the "accordian head".
And also mouse click on "accordian head" should show/hide the accordion-body.
I got the show/hide working through CSS on hover.
But when i club mouse click event , the functionality is not working
here is the sample
http://jsfiddle.net/yf4W8/157/
.accordion-body{display:none;}.accordion:hover div{display:block;}
you need to change
myDivElement.style.display = none;
myDivElement.style.display = block;
to
myDivElement.style.display = "none"; //double quotes are missing
myDivElement.style.display = "block"; //double quotes are missing
Demo
I have created a working demo, please check the link below not it is working on mouse click. Replace your JavaScript code with this and remove the css properties.
function expandAccordionBody(){
var myDivElement = document.getElementById("accbody" );
var cStyle=window.getComputedStyle(myDivElement, null);
if(cStyle.display=='block'){
myDivElement.style.display='none';
}else{
myDivElement.style.display='block';
}
}
Demo
I took a liberty to change your code a bit. This code works.
Hope that this is what you meant to do....
Instead of using pure Javascript I used jQuery event click and hover.
here is the link for working code
click here for DEMO
HTML code;
<div class="accordion">
<div class="headA">
Head
</div>
<div id="accbody" class="accordion-body">
Body
</div>
</div>
CSS code;
.accordion {
border: 1px solid #444;
margin-left: 60px;
width: 30%;
}
.accordion:hover div {
display: block;
}
.accordion-body a {
background-color: green;
display: block;
color: white;
padding: 25px;
text-align: center;
}
.headA a {
text-align: center;
display: block;
background-color: yellow;
padding: 25px;
}
jQuery code;
$(document).ready(function() {
// on page load hide accordion body
var accordionBody = $('#accbody');
accordionBody.hide();
// first make on click event happening
// when user clicks on "Head" accordion "Body will show up"
$('.headA').click(function() {
if (accordionBody.is(':hidden')) {
accordionBody.slideDown(400);
} else {
accordionBody.slideUp(400);
}
});
$('.headA').hover(function() {
if (accordionBody.is(':hidden')) {
accordionBody.slideDown(400);
} else {
accordionBody.slideUp(400); // turn this off if you want only to slide down and not back up
}
});
});
So I'm making a sort of blog posting system or TODO list, however you want to call it.
I want that the following can happen / is possible:
[Working] The user types something in the textarea
[Working] The user clicks on the button.
[Working] A new div will be created with the text of the textarea.
[Working] The textarea will be empty.
[Not Working] The user has got the choice to delete the post by clicking the 'X' on the right side of each '.post' div.
BUT: If I click on the button when there's nothing in the textarea, there appears an empty div, with only an 'X' close button, no background color either. They appear on the same line as the previous message, so you can get a lot of 'X's next to each other.
AND: Clicking the 'X' close button doesn't do anything. No errors in Firefox console.
If it's not clear enough, run this JSFiddle, click the button and I think you'll understand what I mean:

You appear to have two issues:
1) You don't want a post to be created if the textarea is empty
Simple fix . . . check to see if it is empty, before calling the logic to add the new post (and use jQuery's $.trim() to account for only blank spaces):
$('#button').click(function() {
var text = $.trim($('#poster').val());
if (text !== "") {
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
}
});
2) The 'X' buttons are not closing the posts
This also should be a pretty easy fix . . . the reason that they are not working is because the 'X' buttons don't exist when the page is loaded so $('.close-post').click(function() { is not binding to them on page load. You will need to delegate that event binding, so that it will apply to the 'X' buttons that are dynamically added after the page is loaded.
Now, not knowing what version of jQuery that you are using (I can't access jsFiddle from work), I'll point you to the right place to figure out the correct way to do it: https://api.jquery.com/on/
If it is jQuery 1.7 or higher, you would do it like this:
$("#posts").on("click", ".close-post", function() {
$(this).parent().hide();
});
If your version is earlier than that, then investigate the jQuery .delegate() and .live() methods to determine which is the right one to use for your code..
Try this:
$(document).ready(function() {
$('#button').click(function(event) {
event.preventDefault();
var text= $('#poster').val();
if (text === '') {
alert('Nothing to post!');
return;
}
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
});
$('#posts').on('click', '.close-post', function() {
$(this).closest('.post').fadeOut();
});
});
JSFiddle
The way you are doing this, the user will only ever see what they are posting - if you're trying for a chat type where users talk to each other then you will need to store what is being typed on the server side and refresh the screen using something like ajax
but in response to your question, you need to bind the close click like this:
$( "#posts" ).on( "click", ".close-post", function() {
$(this).parent().hide(); // $(this) is the clicked icon, the way you did it above wouldn't as if it had the dollar, it would close all .close-post parents
});
See the part about delegated events: http://api.jquery.com/on/
i have an userscript which traces all the dynamically created tags in javascript of a webpage. the problem here is presently i am using alert box to dispaly the output. The problem with alert() is that it can be very obtrusive. For every alert, you need to click the OK button to proceed which wastes your time. so i want an alternative method like log files other than alert box. how can i do this.
i am restricted to use console.log
I would use some kind of console element statically placed on your page which can be hidden if necessary. See this jsFiddle.
HTML:
<div id="console">
<div class="header">
Console
<span class="expand" onclick="toggleConsole();">+</span>
</div>
<div class="content" style="display: none;"></div>
</div>
CSS:
#console {
position: fixed;
right: 0px;
bottom: 0px;
width: 300px;
border: solid 1px #dddddd;
}
#console .header {
background-color: #ededed;
border: solid 1px #dddddd;
}
#console .header .expand {
padding-right: 5px;
float: right;
cursor: pointer;
}
#console .content {
overflow: auto;
background-color: #F9F9F0;
width: 100%;
height: 180px;
}
Javascript:
function log(text) {
var consoleContent = document.getElementById('console')
.getElementsByClassName('content')[0];
var line = document.createElement('div');
line.className = 'consoleLine';
line.innerHTML = text;
consoleContent.appendChild(line);
}
function toggleConsole() {
var content = document.getElementById('console')
.getElementsByClassName('content')[0];
if (content.style.display === "none") {
content.style.display = "block";
document.getElementById('console')
.getElementsByClassName('expand')[0].innerHTML = "-";
} else {
content.style.display = "none";
document.getElementById('console')
.getElementsByClassName('expand')[0].innerHTML = "+";
}
}
document.onload = function() {
document.getElementById('console')
.getElementsByClassName('expand')[0].onclick = toggleConsole;
};
Use log("some text"); to output to your console !
Install firefox add-on to your Mozilla(if you are using) and you the follwing code:
console.log("test"+your_variable);
So above code will display all logs in console.If IE press F12 and check console.
If a normal user should be able to see it, using the console is not a very user-friendly way.
Define a space on your webpage (a <div> might be handy) where you want the information to be, and just add the messages to that space using javascript (or jQuery) to modify the DOM:
HTML:
<div id='logmessages'>Log messages:</div>
JavaScript
function log(yourMsg) {
document.getElementByID('logmessages').innerHTML() += yourMsg;
}
It might be friendly to allow the user to show/hide the div with a button or another way.
Create a fixed div either at the top, bottom or corner of your page with set width/height and overflow auto, then insert the log entries in it.
I want to display the alert box but for a certain interval. Is it possible in JavaScript?
If you want an alert to appear after a certain about time, you can use this code:
setTimeout(function() { alert("my message"); }, time);
If you want an alert to appear and disappear after a specified interval has passed, then you're out of luck. When an alert has fired, the browser stops processing the javascript code until the user clicks "ok". This happens again when a confirm or prompt is shown.
If you want the appear/disappear behavior, then I would recommend using something like jQueryUI's dialog widget. Here's a quick example on how you might use it to achieve that behavior.
var dialog = $(foo).dialog('open');
setTimeout(function() { dialog.dialog('close'); }, time);
May be it's too late but the following code works fine
document.getElementById('alrt').innerHTML='<b>Please wait, Your download will start soon!!!</b>';
setTimeout(function() {document.getElementById('alrt').innerHTML='';},5000);
<div id='alrt' style="fontWeight = 'bold'"></div>
setTimeout( function ( ) { alert( "moo" ); }, 10000 ); //displays msg in 10 seconds
In short, the answer is no. Once you show an alert, confirm, or prompt the script no longer has control until the user returns control by clicking one of the buttons.
To do what you want, you will want to use DOM elements like a div and show, then hide it after a specified time. If you need to be modal (takes over the page, allowing no further action) you will have to do additional work.
You could of course use one of the many "dialog" libraries out there. One that comes to mind right away is the jQuery UI Dialog widget
I finished my time alert with a unwanted effect.... Browsers add stuff to windows. My script is an aptated one and I will show after the following text.
I found a CSS script for popups, which doesn't have unwanted browser stuff. This was written by Prakash:- https://codepen.io/imprakash/pen/GgNMXO. This script I will show after the following text.
This CSS script above looks professional and is alot more tidy. This button could be a clickable company logo image. By suppressing this button/image from running a function, this means you can run this function from inside javascript or call it with CSS, without it being run by clicking it.
This popup alert stays inside the window that popped it up. So if you are a multi-tasker you won't have trouble knowing what alert goes with what window.
The statements above are valid ones.... (Please allow).
How these are achieved will be down to experimentation, as my knowledge of CSS is limited at the moment, but I learn fast.
CSS menus/DHTML use mouseover(valid statement).
I have a CSS menu script of my own which is adapted from 'Javascript for dummies' that pops up a menu alert. This works, but text size is limited. This hides under the top window banner. This could be set to be timed alert. This isn't great, but I will show this after the following text.
The Prakash script above I feel could be the answer if you can adapt it.
Scripts that follow:- My adapted timed window alert, Prakash's CSS popup script, my timed menu alert.

If you are looking for an alert that dissapears after an interval you could try the jQuery UI Dialog widget.
tooltips can be used as alerts. These can be timed to appear and disappear.
CSS can be used to create tooltips and menus. More info on this can be found in 'Javascript for Dummies'. Sorry about the label of this book... Not infuring anything.
Reading other peoples answers here, I realized the answer to my own thoughts/questions. SetTimeOut could be applied to tooltips. Javascript could trigger them.
by using this code you can set the timer on the alert box , and it will pop up after 10 seconds.
setTimeout(function(){
alert("after 10 sec i will start");
},10000);
You can now use the HTMLDialogElement.
In this example a dialog is created when you click the button, and a timeout function is created to close it:
async function showMessage(message) {
const dialog = document.createElement("dialog");
document.body.appendChild(dialog);
dialog.innerText = message;
dialog.show();
setTimeout(function () {
dialog.close();
}, 1000);
}
<button class="btn" onclick="showMessage('This is my message')">click me!</button>
If you want you can test it on codepen.
function alertWithTimeout(title,message,timeout){
var dialog = $("<div id='dialog-confirm' title='"+title+"'>"+message+"</div>").dialog();
setTimeout(function() { dialog.dialog('close'); }, timeout);
}
alertWithTimeout("Error","This is the message" ,5000);
