我想删除环绕图像的 noscript 标签：

<a href="some_image.jpg">
 <noscript>
  <img src="some_image.jpg">
 </noscript>
</a>

我试过unwrap()了，但是在noscript里面不起作用，接下来我尝试了这个html()方法：

$('a').html(function(index, oldhtml){
   return oldhtml.replace(/\<noscript\\?>/g, '');
});

虽然标签被移除，但它会生成一个字符串而不是 DOM：

<a href="some_image.jpg">
 "
  <img src="some_image.jpg">
 "
</a>

如何在保持 img 元素不变的同时删除 noscript 标签包装器？

您可以用它的内容替换元素：

$('noscript').replaceWith(function() {
    return this.textContent || this.innerText;
    // return $('<div/>').html(this.innerHTML).text();
});

尝试类似的东西 -它实际上是一个非常粗糙的黑客

jQuery(function($){
    $('a:has(noscript)').html(function(){
        return $(this).find('noscript').text()
    })
})

你可以这样试试：

var image=$('noscript').text();
$("noscript").remove();
$("a").append(image);

为什么不保留noscript原样并自己附加图像？

$("noscript").each(function () {
    $('<img src="' + this.parentNode.href + '" />').appendTo(this.parentNode);
});

Noscript's usage today can be logical for <a href="google.com"><p id="javascripton">eg pc/laptop/high quality tablets usage the complete website with all features:images high resolution,javascript<br><h1>OR without javascript so no high resolutions images inserted with a jquery automated script generated from some php+javascript scripts so have usage for 80% mobile application cause almost are from China ,so low quality products=low cpu,low ram :IN THIS CASE SOMEONE CAN THINK TO SWITCH HIS PHONE TO NO JAVASCRIPT USAGE SO IF ANY PROGRAMMER CAN ADAPT AN ENTIRELY APPLICATION TO THE METHOD I USED IN THIS EXAMPLE AUTOMATED HIS BROWSER IS ADAPT FOR ANY RANDOM ACTION ABOUT THE USER CHOISE(YOU UNDERSTAND "TO USE OR NOT JAVASCRIPT") SO HIS CHINESE PHONE CAN BE APROXIMATELLY APROACH LIKE QUALITY OF SPEED EXECUTION THE OTHERS PC/LAPTOPS/TABLETS QUALITY PRODUCTS.<BR><BR>This stupid example is the best example how no script tag can change the quality of services on this planet ,boost the speed of the internet connection and stops unnecessary use of A LOT OF INTERNET TRAFFIC on slow devices..a simple tag can change the entirely dynamic of programmer's views so entirely Planet's beneficts</h1><p></a> <br>
run this code in two instances :<br>with browser javascript enable <br>and without(browser's javascript disable or eg a firefox plugin noscript states on/off)
