Menu
I need some help. I have to write a javascript code that will toggle the a element for show more or less. If I click on show more, it should show the more with a link for show less.
Problem I am Having
1. If I click show more About the Author, instead of just showing more info about just that, it will also show more info about the book description, and who this book is for.. I don't want it to do that, I just want it to show me more info about just that specific one.
2. It's also not showing me or giving me the less link option.
Here is my HTML and JavaScript code.
$(document).ready(function() {
$("#jdom").click(function() {
$("a").toggle(function () {
$(this).text("").siblings("div").hide();
}, function() {
$(this).text("Less").siblings("div").show();
});
});
});article, aside, figure, figcaption, footer, header, nav, section {
display: block;
}
* {
margin: 0;
padding: 0;
}
body {
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 87.5%;
width: 650px;
margin: 0 auto;
border: 3px solid blue;
}
section {
padding: 15px 25px;
}
h1 {
font-size: 150%;
}
h2 {
font-size: 120%;
padding: .25em 0 .25em 25px;
}
div.hide {
display: none;
}
ul {
padding-left: 45px;
}
li {
padding-bottom: .4em;
}
p, a {
padding-bottom: .4em;
padding-left: 25px;

Try This,
$(document).ready(function() {
$(document).on('click','a',function(e){
$(this).text( ($(this).text() == "Show more") ? "Less":"Show more" ) ;
$(document).find($(this).attr('data-target')).toggle();
/*OR WITH ANIMATION*/
/*
if($(this).text() == "Show more"){
$(this).text("Less");
$(document).find($(this).attr('data-target')).slideDown(300);
}else{
$(this).text("Show more");
$(document).find($(this).attr('data-target')).slideUp(300);
}*/
});
/*MORE ACTION*//*
$(document).on('click','#jdom',function(e){
$(document).find('a').each(function(){
$(this).trigger('click');
})
});
*/
});
