this is my first time posting here, please help me. i want to make else if function to display an alert "error not found" if I search any data was not country name in array data. Here is my code below:
function searchByName(){
let display = document.getElementById("data-container");
let textInput = document.getElementById("search").value;
display.innerHTML = "";
let regex = new RegExp(textInput, 'ig');
for(let i=0;i<country.length;i++){
if(regex.test(`${country[i].countryRegion}`)){
display.innerHTML += `
<h3>${country[i].countryRegion}</h3>
<div id="data-negara">
<div id="konfirmasi">
<h4>Konfirmasi</h4>
<p>${country[i].confirmed}</p>
</div>
<div id="sembuh">
<h4>Sembuh</h4>
<p>${country[i].recovered}</p>
</div>
<div id="meninggal">
<h4>Meninggal</h4>
<p>${country[i].deaths}</p>
</div>
</div>
`} else if( regex.test == false){
alert("not found");
break;
}
}
return false;
}Try using trycatch, that’s the easiest solution. The current code in your method cut it and add it to the try section and manage your error handing in the catch block.
Or add an if statement
