Stack Overflow Asked by sys73r on December 2, 2021
I’m trying to read inside a class the UL and then a LI element which contains links but the data to create the URL to finally download the files is separated.
The LI element contains an ID and the <a href title contains the filename, so I’m trying to first get all the LI elements inside the class but I can’t find a way to associate/read each LI ID with the corresponding A HREF TITLE.
This is part of a chrome extension
chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
//this no longer works..
if (request.message == "getLinks") {
var links = [];
$("a").each(function(i, el) {
links.push({ "url": el.href, "description": $(el).text() });
});
chrome.runtime.sendMessage({ "message": "links", "links": links });
//TESTING HERE. so I can create a link to download
const listItems = document.querySelectorAll('.view-items li');
for (let i = 0; i < listItems.length; i++)
{
alert (listItems[i].id);
const urlTitle = document.querySelectorAll('.view-name a');
for (let k = 0; k < urlTitle.length; i++)
{
alert (urlTitle[i].title);
}
}
}
});

// declaring an empty array to contain all the built urls
var array_of_urls = [];
var all_li = document.getElementsByClassName("view-item");
for (var i = 0; i < all_li.length; i++)
{
// get the needed id
var id = all_li[i].getAttribute("id");
// get the filename
var file_to_download = all_li[i].childNodes[1].getAttribute("title");
// build the link
var new_url = "https://myhost/files/"+id+"/"+file_to_download+".pdf";
array_of_urls.push(new_url); // push the URL in an array
// if you need to put the each built link in its relative href
all_li[i].childNodes[1].setAttribute("href", new_url);
}
console.log(array_of_urls); // dislay all the built URL
<ul class="view-items">
<li id="VBGC00" class="view-item">
<a href="#" title="my-file-name-to-download" class="text_button>my-file-name-to-download.pdf"> link 0 </a>
</li>
<li id="VBGC01" class="view-item">
<a href="#" title="my-file-name-to-download-1" class="text_button>my-file-name-to-download.pdf"> link 1 </a>
</li>
<li id="VBGC02" class="view-item">
