如何使用jQuery在元素中添加元素

Question

I have some code like this:

<p>Nuno</p>
<p>Eimes</p>

How can I manipulate it like this:

<p><a href="name/Nuno">Nuno</a></p>
<p><a href="name/Eimes">Eimes</a></p>

I've tried:

var name=$(this).text();
$( "p" ).each(function() {
  $(this).prepend('<a href="id/'+ $(this).text() +'"> ');
$(this).append("</a>");
});

but it results:

<p><a href="id/Nuno"> </a>Nuno</p>
<p><a href="id/Eimes"> </a>Eimes</p>

the <a> is not inside $('p').text(); also if i change to name . it didn't show the value.

Answer 1

$( "p" ).each(function() {
   var text = $(this).text();
   $(this).wrapInner('<a href="name/'+text+'"></a>');
 });

Answer 2

Simple and .wrapInner()

$('p').wrapInner(function(){
    return '<a href="name/' + $(this).text() + '" />' // even this.innerHTML instead of $(this).text() will do
})

Demo: Fiddle

Answer 3

Once you've extracted the name, I would just rewrite the whole code within the <p></p> tags again:

var name=$(this).text();
$( "p" ).each(function() {
  $(this).html('<a href="name/'+ $(this).text() +'">' + $(this).text() + '</a>');
});

Answer 4

You just need to grab the inner stuff, then replace everything in the tag with the new HTML:

var name=$(this).text();
$( "p" ).each(function() {
    old = $(this).html();
    $(this).html('<a href="id/'+ old +'">'+old+'</a>');
});

Answer 5

Demo

$('p').html(function () {
    return '<a href="name/' + this.innerHTML + '">' + this.innerHTML + '</a>';
});

.html()
