I am looking to filter out specific values from an array.
var array = [<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2149444d4d4e615840494e4e0f424e4c">[email protected]</a>, www.hello.com, <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="5b333e3737341b3c363a323775383436">[email protected]</a>];
I need to remove any element in the array that includes an @ sign. For example, I should only have www.hello.com when I display the alert.
Loop through each element in the array and check if it contains the "@" symbol. If it does, remove that element from the array.
It is advisable to avoid deleting or changing the index of elements in an array within a loop. This is because the array gets re-indexed when using .splice(), leading to the possibility of skipping over an index when an element is removed.
Instead, consider filtering out the elements to create a new array that meets your desired criteria.
var array = [
'<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9ff7faf3f3f0dfe6fef7f0f0b1fcf0f2">[email protected]</a>',
'www.hello.com',
'<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f69e939a9a99b6919b979f9ad895999b">[email protected]</a>'];
var newArray = array.filter(function(item){
return item.indexOf('@') ==-1
})
console.log(newArray)
If you're looking to achieve this task, one method is to utilize a Regular Expression in combination with a second array. Here's an example:
var array = ['<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a3cbc6cfcfcce3dac2cbcccc8dc0ccce">[email protected]</a>', 'www.hello.com', '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="83ebe6efefecc3e4eee2eaefade0ecee">[email protected]</a>'];
var array2 = [];
for (var i = 0; i < array.length; i++) {
if (!(/@/.test(array[i]))) {
array2.push(array[i]);
};
};
alert(array2);One way to filter elements from an input array is to use a loop and push matching elements into a new output array.
var array = [
'<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="157d7079797a556c747d7a7a3b767a78">[email protected]</a>',
'www.hello.com',
'<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b6ded3dadad9f6d1dbd7dfda98d5d9db">[email protected]</a>'];
var newArray = [];
array.forEach(x => {
if(x.indexOf('@') === -1)
newArray.push(x);
});
