我只想要那个 div 的标题

Question

I want only headings from that div . I have many more other things it that div .

let content = document.getElementsByClassName("myClass");

for (item in content){
    console.log(content[item].innerText);
}

Answer 1

What do you mean by headings? <h1> , <h2> tags? You could change this to use a querySelector instead.

document.querySelectorAll('.myClass h1') 

This will return all the elements inside the element with "myClass"

Answer 2

Use querySelectorAll() and loop through with Array.forEach()

 let content = document.querySelectorAll(".myClass > h1, .myClass > h2, .myClass > h3, .myClass > h4, .myClass > h5"); content.forEach(el => { console.log(el.innerText) })

 <div class="myClass"> <h1>Heading 1</h1> <p>Text</p> </div> <div class="myClass"> <h2>Heading 2</h2> <p>Text</p> </div>
