<a>使用jQuery</a>将<a>文本字符串</a>转换<a>为dom元素</a>

Question

How can I convert the text in a link to an html element?

I'm targetting the text with $('a').text(); which returns the value but I can't add the element to it.

I've tried this:

var someText = $('a').text();
var theElement = $('< p >' + someText + '< /p >');
someText.replaceWith(theElement);

---

I know this supposedly would add a text element inside the link which is not the best practice but not even this works.

what I really need is to remove the whole text and rewrite it immediately after de link as a text element.

any help is appreciated. thank you

markup:

<li>
<a href="/"> <img src="image.png"> text to be converted to element </a>
</li>

what I want:

<li>
<a href="/"> <img src="image.png"></a>
<p> text to be converted to element </p>
</li>

Since someText is a string, not a jQuery element, you can't call .replaceWith() on it. Try something like this:

var someLink = $('a');
var someText = someLink.text();
var theElement = $('<p>' + someText + '</p>'); // no spaces inside tags
someLink.replaceWith(theElement);

UPDATE Since you added new information to your question, here's a solution to meet your needs:

var someLink = $('a');
var someText = someLink.text();
var someImg = someLink.find('img');
var theElement = $('<p>' + someText + '</p>');
someLink.html(someImg).after(theElement);

var anchor = $('li a');
anchor.after('<p>' + anchor.text() + '</p>')
    .contents()
    .filter(function(){
        return (this.nodeType == 3);
    })
    .remove();

Found the code for removing the text afterward here https://stackoverflow.com/a/17852238/1415091

I'd suggest:

// iterate over each of the <a> elements within <li> elements:
$('li a').each(function() {
  // create a <p> element, setting its text
  // to that of the 'this' element (the <a>):
  $('<p>', {
    'text': this.textContent
  // insert that created <p> after the current <a> element:
  }).insertAfter(this);

  // filtering the childNodes of the current <a>:
  $(this).contents().filter(function() {
    // keeping only those that are of nodeType === 3
    // and therefore are textNodes:
    return this.nodeType === 3;
  // removing those nodes:
  }).remove();
});

 $('li a').each(function() { $('<p>', { 'text': this.textContent }).insertAfter(this); $(this).contents().filter(function() { return this.nodeType === 3; }).remove(); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul> <li> <a href="/"> <img src="http://lorempixel.com/300/300/people" />text to be converted to element</a> </li> </ul>

Use .html()

var someText = 'Hey!';
$('#test').html('<p>' + someText + '</p>');
