I'm making a discord bot with discord.js. jQuery get the image src
looked for the most relevant article, but it's different from what I'm trying to do.
I'd like to receive several srcs of img in the span tag by array.
<div class="jewel__wrap">
<span id="gem00" class="jewel_btn" data-grade="3" data-item="E595062cGem_000">
<span class="jewel_img">
<img src="https://xxx/60.png" alt=""> // this src
</span>
<span class="jewel_level">Lv.5</span>
</span>
<span id="gem01" class="jewel_btn" data-grade="3" data-item="E595062cGem_001">
<span class="jewel_img">
<img src="https://xxx/50.png" alt=""></span> // this src
<span class="jewel_level">Lv.5</span>
</span>
</div>
const jewel = $(".jewel_level").text();
const jewel2 = $(".jewel_img").find('img').attr("src");
console.log("jewel : ", jewel, "jewel2 : ", jewel2);
jewel receives both lv.5 and ex) lv.5lv.5. jewel2 only receives one src.
How should I bring it?
console
jewel : Lv.5Lv.5 jewel2 : https://xxx/60.png
The problem with jQuery's .attr() is...
Get the value of an attribute for the first element in the set of matched elements
Instead, you can use jQuery's .map() to transform a collection of elements into an array
const sources = $(".jewel_img > img")
.map((_, { src }) => src) // extract property
.get() // get the array out of the jQuery object
console.log("sources", sources)<!-- minified HTML -->

<div class="jewel__wrap"> <span id="gem00" class="jewel_btn" data-grade="3" data-item="E595062cGem_000"> <span class="jewel_img"> <img src="https://xxx/60.png" alt=""> </span> <span class="jewel_level">Lv.5</span> </span> <span id="gem01" class="jewel_btn" data-grade="3" data-item="E595062cGem_001"> <span class="jewel_img"> <img src="https://xxx/50.png" alt=""></span> <span class="jewel_level">Lv.5</span> </span></div>You may even want to treat the text in a similar way and collect all the data into objects
const data = $(".jewel_btn")
.map((_, btn) => {
const $btn = $(btn)
return {
image: $btn.find(".jewel_img img").attr("src"),
level: $btn.find(".jewel_level").text()
}
})
.get()
console.log("data", data)<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.slim.min.js"></script>
