I have a page full of different links that each have a class of .post-link
.
In the following function, I'd like the line $(this).html('loading...');
to target the specific .post-link
div that is clicked. How would I go about achieving this? I feel I should create some sort of variable but I'm a bit lost. Any help would be appreciated.
$('.post-link').click(function(e) {
e.preventDefault();
var post_id = $(this).attr('rel');
var ajaxURL = site.ajaxurl;
function projectShow() {
$.ajax({
type: 'POST',
cache: false,
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
beforeSend: function() {
$('#project-wrapper').addClass('activated');
$(this).html('loading...'); <--line in question
},
success: function(response) {
$('#project-container').html(response);
$('.post-container').addClass('fadeInUp');
$('.close-button').addClass('fadeOutDown');
$('#project-wrapper .entry-title').shuffleLetters();
return false;
}
});
}
Edit
Here is how my HTML is set up:
<a class="post-link"><img src="image.jpg"></a>
Using Alexander's solution, the "loading..." text shows up like this:
<a class="post-link"><img src="image.jpg">loading...</img></a>
Is there a way to make it show like this?
<a class="post-link"><span>loading...</span><img src="image.jpg"></img></a>
Of course given that I wrap the text in span
tags?
Update
$('.post-link').click(function(e) {
e.preventDefault();
var post_id = $(this).attr('rel'),
ajaxURL = site.ajaxurl;
function projectShow() {
$.ajax({
type: 'POST',
cache: false,
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
beforeSend: function() {
$('#project-wrapper').addClass('activated');
$('<span class="loading">loading...</span>').insertBefore($(e.currentTarget).find('img'));
},
success: function(response) {
$('.loading').remove();
$('#project-container').html(response);
$('.post-container').addClass('fadeInUp');
$('.close-button').addClass('fadeOutDown');
$('#project-wrapper .entry-title').shuffleLetters();
return false;
}
});
}
if ($(window).scrollTop() != 0) {
projectShow();
$('html, body').animate({
scrollTop : 0
},100);
} else {
projectShow();
}
});
Use
$('<span>loading...</span>').insertBefore($(e.currentTarget).find('img'));
or
$(e.currentTarget).prepend('<span>Loading</span>');
because this
in beforeSend
does not refer to element
You could try something like:
$('.post-link').click(function(e) {
e.preventDefault();
// set a variable as a reference to 'this'
// prefixing variables containing jquery object with a '$'
// as an easy way to spot them in your code
var $self = $(this),
post_id = $(this).attr('rel'),
ajaxURL = site.ajaxurl;
function projectShow() {
$.ajax({
type: 'POST',
cache: false,
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
beforeSend: function() {
$('#project-wrapper').addClass('activated');
$self.html('loading...');
// use if .post-link is a text element
$self.prepend('<span>loading...</span>')
// if your .post-link is an image
},
success: function(response) {
$('#project-container').html(response);
$('.post-container').addClass('fadeInUp');
$('.close-button').addClass('fadeOutDown');
$('#project-wrapper .entry-title').shuffleLetters();
return false;
}
});
}
Although Alexander's answer is better as long as you don't override/re-declare the e
In browsers which support ES5 (IE >= 9), you can simply use .bind(this)
to get context.
beforeSend: (function() {
$('#project-wrapper').addClass('activated');
$(this).prepend('<span>loading...</span>');
}).bind(this),
You may have overcomplicated it a bit. Why do it in beforeSend
? Just do it like this:
$('.post-link').click(function(e) {
e.preventDefault();
var post_id = $(this).attr('rel');
var ajaxURL = site.ajaxurl;
// do it here:
$('#project-wrapper').addClass('activated');
$(this).find('img').before('<span>loading...</span>');
function projectShow() {
$.ajax({
type: 'POST',
cache: false,
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
success: function(response) {
$('#project-container').html(response);
$('.post-container').addClass('fadeInUp');
$('.close-button').addClass('fadeOutDown');
$('#project-wrapper .entry-title').shuffleLetters();
return false;
}
});
}
// I guess you are calling projectShow() somewhere in here
});
尝试使用此代码
$(this).parent('.post-link').html('loading....');
