Question

我想删除环绕图像的noscript标记：

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

我尝试unwrap()，但它在noscript中无效，接下来我尝试了html()方法：

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

虽然删除了标记，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元素不受影响的同时删除noscript标记包装？

Answer 1

你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();
});

Answer 2

尝试类似的事情 - 它实际上是一个非常粗暴的黑客

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

Answer 3

您可以尝试这种方式：

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

Answer 4

为什么不保留noscript原样并自己附加图片？

$("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)
