javascript script used to download images

This time I will bring you the javascript script used to download images. What are the precautions for using the javascript script to download images? The following is a practical case, let’s take a look.

Function Description:
I often find a problem when browsing picture websites. When I want to copy pictures to the local computer, I often save them as, save as, save as. Oops, that's a bit troublesome. So the function of this script is to pop out all the pictures when you are on a picture website, and then just click on the picture you want to download. Of course, using the browser plug-in directly is also a good choice.
--The code couldn't be simpler, so I won't explain it in detail.
--You can save the script to your favorites and just click it when you want to use it.
--Possibly, older versions of browsers do not support click-to-download

javascript:(  function(){ var ALLA= $("html").find("img");  var code=""; for(var aa=0;aa<ALLA.length ;aa++){  code=code+"<a href=&#39;"+$(ALLA[aa]).attr("src")+"&#39; download >"+"<img src=&#39;"+$(ALLA[aa]).attr("src")+"&#39;/></a>";;  }; if (code!=&#39;&#39;){  var newwin=window.open(&#39;&#39;,&#39;&#39;,&#39;&#39;); newwin.opener = null ;  newwin.document.write(code); newwin.document.close(); };   }  )()

[Code] If the image cannot pop up, it may be that JQuery has not been added to the web page (this is an example of adding JQuery code)

javascript:(function(){  try  {   $("body").html();  alert("jq%E5%B7%B2%E7%BB%8F%E5%BC%95%E5%85%A5"); }  catch (e)  {  new_element=document.createElement("script"); new_element.setAttribute("type","text/javascript"); new_element.setAttribute("src","http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.1.4.min.js"); document.body.appendChild(new_element);  } })()
