Using jQuery to find <em> tags and adding content within them - html

Question

The users on my review type of platform highlight titles (of movies, books etc) in <em class="title"> tags. So for example, it could be:
<em class="title">Pacific Rim</em>
Using jQuery, I want to grab the content within this em class and add it inside a hyperlink. To clarify, with jQuery, I want to get this result:
<em class="title">Pacific Rim</em>
How can I do this?

Answer 1

Try this:
var ems = document.querySelectorAll("em.title");
for (var i = 0; i < ems.length; ++i) {
if (ems[i].querySelector("a") === null) {
var em = ems[i],
text = jQuery(em).text();
var before = text[0] == " ";
var after = text[text.length-1] == " ";
text = text.trim();
while (em.nextSibling && em.nextSibling.className && em.nextSibling.className.indexOf("title") != -1) {
var tmp = em;
em = em.nextSibling;
tmp.parentNode.removeChild(tmp);
text += jQuery(em).text().trim();
++i;
}
var link = text.replace(/[^a-z \-\d']+/gi, "").replace(/\s+/g, "+");
var innerHTML = "<a target=\"_blank\" href=\"http://domain.com/?=" + link + "\">" + text + "</a>";
innerHTML = before ? " " + innerHTML: innerHTML;
innerHTML = after ? innerHTML + " " : innerHTML;
ems[i].innerHTML = innerHTML;
}
}

Answer 2

$("em.title").each(function() {
var content = $(this).text();
var parameter_string = content.replace(/ /g, "+").trim();
parameter_string = encodeURIComponent(parameter_string);
var new_content = '' + content + '';
$(this).html(new_content);
});
If you want to remove any kind of punctuation, refer to this other question.

Answer 3

$('em.title').html(function(i,html) {
return $('<a/>',{href:'http://domain.com/?='+html.trim().replace(/\s/g,'+'),text:html});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<em class="title">Pacific Rim</em>
UPDATE 1
The following updated version will perform the following:
Grab the contents of the em element
Combine with the contents of the next element, if em and remove that element
Create a query string parameter from this with the following properties
Remove the characters ,.&
Remove html
Append the query parameter to a predetermined URL and wrap the unmodified contents in an e element with the new URL.
DEMO
$('em.title:not(:has(a))').html(function() {
$(this).append( $(this).next('em').html() ).next('em').remove();
var text = $(this).text().trim().replace(/[\.,&]/g,'');
return $('<a/>',{href:'http://domain.com/?par='+encodeURIComponent(text),html:$(this).html()});
});
Or DEMO
$('em.title:not(:has(a))').html(function() {
$(this).append( $(this).next('em').html() ).next('em').remove();
var text = $(this).text().trim().replace(/[\.,&]/g,'').replace(/\s/g,'+');
return $('<a/>',{href:'http://domain.com/?par='+text,html:$(this).html()});
});
UPDATE 2
Per the comments, the above versions have two issues:
Merge two elements that may be separated by a text node.
Process an em element that's wrapped in an a element.
The following version resolves those two issues:
DEMO
$('em.title:not(:has(a))').filter(function() {
return !$(this).parent().is('a');
}).html(function() {
var nextNode = this.nextSibling;
nextNode && nextNode.nodeType != 3 &&
$(this).append( $(this).next('em').html() ).next('em').remove();
var text = $(this).text().trim().replace(/[\.,&]/g,'').replace(/\s/g,'+');
return $('<a/>',{href:'http://domain.com/?par='+text,html:$(this).html()});
});

Answer 4

Actually,if you just want to add a click event on em.title,I suggest you use like this:
$("em.title").click(function(){
q = $(this).text()
window.location.href = "http://www.domain.com/?="+q.replace(/ /g,"+")
}
you will use less html code on browser and this seems simply.
In addition you may need to add some css on em.title,like:
em.title{
cursor:pointer;
}

Answer 5

Something like this?
$(document).ready(function(){
var link = $('em').text(); //or $('em.title') if you want
var link2 = link.replace(/\s/g,"+");
$('em').html('' + link + '');
});
Ofcourse you can replace the document ready with any type of handler

Answer 6

$('.title').each(function() {
var $this = $(this),
text = $this.text(),
textEnc = encodeURIComponent(text);
$this.empty().html('' + text + '');
});
