How to search for items in array properties?

December 19, 2021

I am trying to make a simple website(without CSS3) to search for items in an array. My way of accomplishing this goal is to search in the ‘title’ or ‘desc’ properties of an item in the array. My expected result is to get titleOfItem + ‘ fizz’ in the console if the title includes the keyword from the input. Instead, I get the following error:

EDIT: I fixed this by adding a condition instead of a number in the for loop.

Here is my HTML5 code:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width">
    <title>replit</title>
    <link href="style.css" rel="stylesheet" type="text/css" />
  </head>
  <body>
    <input id="keywordText" type="text">
    <button id="submit" onclick="search()">Search</button>
    <script src="script.js"></script>
  </body>
</html>

and Here is my JS code:

const items = {
  john:{title:'john', desc:"doe", elem:document.getElementById('john')},
  jane:{title:'jane', desc:"doe", elem:document.getElementById('jane')}
}

let allItems = []
for (var key in items) {
  allItems.push(items[key])
}



function search() {
  let keyword = document.getElementById('keywordText').value;
  for (let count = 0; allItems.length; count++) {
    let titleOfItem = allItems[count].title
    if (titleOfItem.includes(keyword)) {
      console.log(titleOfItem + ' fizz')
    } else {
      console.log(titleOfItem + ' buzz')
    }
  }
}

Is there something that I am doing wrong in this code? Also, for organization purposes, is there some way to get this information straight from the first array?

Thank you for your help!

>Solution :

for (let count = 0; count < allItems.length; count++) {

}

You are getting the error because you did not specify how long the count value will continue in the for loop. You can fix the problem by updating the code like this.
