How to pass attribute value on double click using jquery - javascript

I want to pass blank value on single click function and want to redirect on double click.
Here my code for HTML
Code for j-query
$(function () {
var clicker = $('#Nav a');
$(this).click(function () {
$(this).attr('href', '');
});
clicker.dblclick(function () {
window.location = $(this).attr("href");
});
}
kindly suggest how i can pass same attribute value for two different function or any other way to do that.

You can use e.preventDefault() to prevent redirection on single click:
$(function () {
var clicker = $('#Nav a');
clicker.click(function (e) {
e.preventDefault();
});
clicker.dblclick(function () {
window.location = $(this).attr("href");
});
})
Also, note that $(this) of your click function is not map to any element at this moment. Since you've assigned var clicker = $('#Nav a') then you can use clicker.click instead.

How to shorten this jQuery onClick FadeOut to next Page code?

I am trying to do a nice FadeOut if you click on a Link. The following Code is perfectly working.
My question is: How can I shorten these functions? Demo: Here
$(document).ready(function () {
var newLocation = '';
$('a, .fadeLink').on('click', function(e){
e.preventDefault();
newLocation = this.href;
$('body').fadeOut(1000, changeLocation);
});
function changeLocation() {
window.location = newLocation;
}
});
Your code actually looks quite good already. You could shorten it (not necessarily better) by taking an arrow function instead of the additional function, so you can closure the link:
$(document).ready(function () {
$('a, .fadeLink').on('click', function(e){
e.preventDefault();
$('body').fadeOut(1000, () => window.location = this.href);
});
});
You can lose the $(document).ready function by placing the JavaScript code just before closing the <body> tag. Also, you don't have to define newLocation in the upper scope, you can pass it to the changeLocation function instead:
$('a, .fadeLink').on('click', function(e) {
e.preventDefault();
var location = this.href;
$('body').fadeOut(1000, function() {
changeLocation(location);
});
});
function changeLocation(location) {
window.location = location;
}
You could also get rid of the changeLocation function:
$('a, .fadeLink').on('click', function(e){
e.preventDefault();
var location = this.href;
$('body').fadeOut(1000, function() {
window.location = location;
});
});
In the end it's a matter of preference. Keep in mind that compacter code is not always better code.

Display read more button

I want to use a read more button after a text is larger than 300 characters.
I use this jQuery to fix this, but it is not working as I want.
var $j = jQuery.noConflict();
$j('.reviewtekst').each(function() {
var $pTag = $j(this).find('p');
if($pTag.text().length > 300){
var shortText = $pTag.text();
shortText = shortText.substring(0, 300);
$pTag.addClass('fullArticle').hide();
$pTag.append('<a class="read-less-link">Lees minder</a>');
$j(this).append('<p class="preview">'+shortText+'</p><div class="curtain-shadow"></div><a class="read-more-link">Read more</a>');
}
});
$j(document).on('click', '.read-more-link', function () {
$j(this).parent().hide().prev().show();
});
$j(document).on('click', '.read-less-link', function () {
$j(this).parent().hide().next().show();
});
See this JSFiddle: https://jsfiddle.net/8cm67cun/1/
How can I make this work, to display the <a> class outside the <p> class.
Here is updated version https://jsfiddle.net/8cm67cun/2/ now it works fine with a tag outside the p
$j(document).on('click', '.read-more-link', function () {
$j(this).hide().parent().find('.preview').hide().prev().show();
});
$j(document).on('click', '.read-less-link', function () {
$j(this).parent().hide().next().show();
$j(this).parents('.reviewtekst').find('.read-more-link').show();
});

How to change text to textbox on clicking it

Here is the fiddle for changing the label's value by clicking on it.
But i don't want to do it while i click on the edit (href)
I just want to click on the name and change it to textbox and while i take the mouse outside it should change back to label
How can i do this ?
Here's the jquery code i have
$(document).ready(function() {
$('a.edit').click(function () {
var dad = $(this).parent().parent();
dad.find('label').hide();
dad.find('input[type="text"]').show().focus();
});
$('input[type=text]').focusout(function() {
var dad = $(this).parent();
$(this).hide();
dad.find('label').show();
});
});
How about something like this. Demo
$(document).ready(function() {
$('.control-label').click(function () {
$(this).hide();
$(this).siblings('.edit-input').show();
});
$('.edit-input').focusout(function() {
$(this).hide();
$(this).siblings('.control-label').text($(this).val()).show();
});
});
You could try it with this modified version of the fiddle:
$(document).ready(function() {
$('.control-label').click(function () {
$(this).hide();
var dad = $(this).parent();
dad.find('input[type="text"]').show().focus();
});
$('input[type=text]').focusout(function() {
var dad = $(this).parent();
$(this).hide();
dad.find('label').text(this.value).show();
});
});
It doesn´t set the default value that was in the label before though.
Just change the target of your click function from:
$('a.edit').click(function () {
to
$('.text-info').click(function () {
You could also add a hover function if you want the input to be hidden on mouseout rather than when clicking outside. For example:
$('input[type=text]').hover(function () {
}, function () {
var dad = $(this).parent();
$(this).hide();
dad.find('label').show();
});
Here your adjusted fiddle.

jQuery loader calling function

This is a simple loading script from nettuts and I tried to modify it to suit my needs.
But I can't get function "res," which resizes loaded elements, to happen BEFORE function shownewcontent runs. Now it resizes after it is visible, which is very bad looking.
But if I place call the function sooner, nothing happens, because the content is not yet loaded.
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('#menu a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php #content';
$('#content').load(toLoad);
}
});
$('#menu a').click(function(){
var toLoad = $(this).attr('href')+' #content';
$('#content').hide('slow',loadContent);
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
function loadContent() {
$('#content').load(toLoad,'',showNewContent());
}
function showNewContent() {
$('#content').show("0", res)
}
return false;
});
});
You have res() defined as the callback to show(), meaning it will get called after the show() function completes.
I would change your callback structure so that it contains all of the work you want to do:
$('#menu a').click(function(e) {
var toLoad = $(this).attr('href') + ' #content';
$('#content').hide('slow', function() {
var self = this;
$(self).load(toLoad, '', function() {
res();
$(self).show("0");
});
});
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
e.preventDefault();
}
Then you don't need the function definitions inside your click handler.
FYI, instead of return false;, it would be better to use e.preventDefault(); at the end of your click handler, though. You will have to define e as a parameter to the click callback function. See this for the return false; vs. e.preventDefault() debate.
Additionally, if the resizing is taking a noticeable amount of time, you might want to have the res() function take a call back in the same fashion that show() does. Then you can show the content only once it's loaded and resized.

Using jQuery post

I have a link that posts to a url (ajax). Then I want to hide the entire li.
HTML
<li>Product Name Delete</li>
JQUERY
$(function(){
$(".del").click(function () {
var link = $(this).attr('href');
$.post(link, function() {
$(this).parent().slideUp();
return false;
});
event.preventDefault();
});
});
The this-keyword in the success-handler passed to $.post does not refer to the anchor element, so your code won't work. You can easily fix this by saving a reference to the li-element outside the success-handler:
$(function(){
$(".del").click(function () {
var link = $(this).attr('href');
var li = $(this).parent();
$.post(link, function() {
li.slideUp();
return false;
});
event.preventDefault();
});
});
