search text march Entire text

developers. I need help. I have given below the code. when I type anything in the search box typed value matches the beginning of a list item. But I want when I type anything in the search box typed value to match any part of the search item and the text color will be red. I try so many times to do it.

function myFunction(e) {
  // find all `li` > a elements
  let col=document.querySelectorAll('ul#myUL li a');
      // iterate through all elements; re-hide & remove className from each.
      col.forEach(n=>{
      
        n.parentNode.style.display='none';
        n.classList.remove('bold');
        
        // if the typed value matches the beginning of a list item; display the text & assign Bold className
        if( this.value.length > 0 && this.value.trim()!='' && n.textContent.toLowerCase().startsWith( this.value.toLowerCase() ) ){
        
          n.parentNode.style.display='block';
          // make the whole word bold
          //n.classList.add('bold');
          
          // make the matched portion bold
          n.innerHTML = `<span class="bold">${this.value}</span>` + n.textContent.substr(this.value.length)
        }
      });
}



document.querySelector('input[name="search"]').addEventListener('keyup',myFunction);
* {
  box-sizing: border-box;
}

#myInput {
  background-image: url('/css/searchicon.png');
  background-position: 10px 12px;
  background-repeat: no-repeat;
  width: 100%;
  font-size: 16px;
  padding: 12px 20px 12px 40px;
  border: 1px solid #ddd;
  margin-bottom: 12px;
}

#myUL {
  list-style-type: none;
  padding: 0;
  margin: 0;
}
#myUL li{
  display:none;
}

#myUL li a {
  border: 1px solid #ddd;
  margin-top: -1px; /* Prevent double borders */
  background-color: #f6f6f6;
  padding: 12px;
  text-decoration: none;
  font-size: 18px;
  color: black;
  display: block
}

#myUL li a:hover:not(.header) {
  background-color: #eee;
}

.bold{font-weight:bold;color:red
<input name='search' type="text" placeholder="Search for names.." title="Type in a name" />
<ul id="myUL">
  <li><a href="#">Adele</a></li>
  <li><a href="#">Agnes</a></li>
  <li><a href="#">Billy</a></li>
  <li><a href="#">Bob</a></li>
  <li><a href="#">Calvin</a></li>
  <li><a href="#">Christina</a></li>

Answer

Use includes() instead of startsWith(). To display the found text, you need to display the text before as well as the text after.

function myFunction(e) {
  // find all `li` > a elements
  let col=document.querySelectorAll('ul#myUL li a');
      // iterate through all elements; re-hide & remove className from each.
      col.forEach(n=>{
      
        n.parentNode.style.display='none';
        n.classList.remove('bold');
        
        // if the typed value matches the beginning of a list item; display the text & assign Bold className
        if( this.value.length > 0 && this.value.trim()!='' && n.textContent.toLowerCase().includes( this.value.toLowerCase() ) ){
        
          n.parentNode.style.display='block';
          // make the whole word bold
          //n.classList.add('bold');
          
          // make the matched portion bold
          n.innerHTML = n.textContent.substr(0,n.textContent.toLowerCase().indexOf(this.value.toLowerCase()))+`<span class="bold">${this.value}</span>` + n.textContent.substr(n.textContent.toLowerCase().indexOf(this.value.toLowerCase())+this.value.length)
        }
      });
}



document.querySelector('input[name="search"]').addEventListener('keyup',myFunction);
* {
  box-sizing: border-box;
}

#myInput {
  background-image: url('/css/searchicon.png');
  background-position: 10px 12px;
  background-repeat: no-repeat;
  width: 100%;
  font-size: 16px;
  padding: 12px 20px 12px 40px;
  border: 1px solid #ddd;
  margin-bottom: 12px;
}

#myUL {
  list-style-type: none;
  padding: 0;
  margin: 0;
}
#myUL li{
  display:none;
}

#myUL li a {
  border: 1px solid #ddd;
  margin-top: -1px; /* Prevent double borders */
  background-color: #f6f6f6;
  padding: 12px;
  text-decoration: none;
  font-size: 18px;
  color: black;
  display: block
}

#myUL li a:hover:not(.header) {
  background-color: #eee;
}

.bold{font-weight:bold;color:red
<input name='search' type="text" placeholder="Search for names.." title="Type in a name" />
<ul id="myUL">
  <li><a href="#">Adele</a></li>
