用xquery插入jQuery后的javascript代码

Question

我试图在html格式化文本中插入javascript代码。所以我用这个jQuery代码：

function getActualWords(node) { 
 
    return node.textContent.split(/\s+/).filter(function(word) { 
 
    return word.trim().length; 
 
    }); 
 
} 
 

 
function insertElemAfterNthWord(opts) { 
 
    var defaults = { 
 
    'nth': 5, 
 
    'elemText': 'new element', 
 
    'elemTag': 'div' 
 
    }; 
 

 
    for (var prop in opts) { 
 
    if (opts.hasOwnProperty(prop)) { 
 
     defaults[prop] = opts[prop]; 
 
    } 
 
    } 
 

 
    var d = defaults, 
 
    tag = d.elemTag.replace(/<|>/g, ''), 
 
    elem = document.createElement(tag); 
 

 
    elem.textContent = d.elemText; 
 

 
    d.nth = parseInt(d.nth, 10); 
 

 
    if (d.node) { 
 
    var n = d.node.firstChild, 
 
     words = getActualWords(n), 
 
     wordCount = words.length; 
 

 
    while ((n.nodeType !== 3 || d.nth > wordCount) && n.nextSibling) { 
 

 
     n = n.nextSibling; 
 
     words = getActualWords(n); 
 
     wordCount = words.length; 
 
    } 
 
    if (getActualWords(n).length < d.nth) { 
 
     return; 
 
    } else { 
 
     var w = getActualWords(n).slice(0, d.nth).pop(), 
 
     i = n.textContent.indexOf(w); 
 
     n.splitText(i + w.length); 
 
     n.parentNode.insertBefore(elem, n.nextSibling); 
 
     n.parentNode.insertBefore(document.createTextNode(' '), n.nextSibling); 
 
     n.parentNode.normalize(); 
 

 
     return elem; 
 
    } 
 

 
    } 
 
} 
 

 

 
insertElemAfterNthWord({ 
 
    'nth': 10, 
 
    'elemTag': 'span', 
 
    'elemText': 'this is the newly-added text inside the newly-added element!', 
 
    'node': document.querySelector('div > div') 
 
}).classList.add('newlyAdded');

span { 
 
    color: #f90; 
 
} 
 
div { 
 
    margin-left: auto; 
 
    margin-right: auto; 
 
} 
 
.newlyAdded { 
 
    background-color: #ffa; 
 
}

<div class="newsitem_text"> 
 
    <div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec pellentesque urna eu pulvinar maximus. Sed elit nunc, vestibulum ut eros vitae, pellentesque rhoncus ipsum. In et metus non diam porttitor maximus iaculis nec lectus. Quisque sodales scelerisque 
 
    auctor. Nam rutrum venenatis eros, eu condimentum erat placerat ut. Pellentesque sed tempus sem, eu viverra ipsum. Vestibulum nec turpis convallis, dapibus massa vitae, posuere mauris. Suspendisse mattis tincidunt lorem. Aliquam erat volutpat. Nullam 
 
    at tincidunt erat, maximus laoreet ipsum.</div>

这里找到：

Insert a <br /> tag after x words using jQuery

是否有可能与例如AdSense中的JavaScript代码替换

'elemText': 'this is the newly-added text inside the newly-added element!' 

？

Answer 1

您可以使用span应答器，并像jQuery容易替换它：

'elemText':'<span class="adsense">this is the newly-added text inside the newly-added element!</span>' 

而只是用jQuery取代：

$('.adsense').html('adsense code');
