Is there a way to retrieve the ID of an input field that has a specific class attribute?
For example:
<input id="first" class="failed" />
<input id="last" class="failed" />
<input id="city" class="failed" />
<input id="state" class="failed" />
I am looking for a method to display all IDs that have the class "failed" after clicking a button or executing a command.
Notify me of any ID that has the failed class after pressing a button or executing a command.
Utilize the class selector to target elements with a specific class. You can loop through all elements using each(). Attach a click event to the button, and use the button's ID as the selector to bind the event.
HTML
<input id="first" class="failed" />
<input id="last" class="failed" />
<input id="city" class="failed" />
<input id="state" class="failed" />
<input type="button" id="btn" value="click" />
Javascript
$('#btn').click(function () {
$('.failed').each(function () {
alert(this.id);
});
});
Utilize the .map() method in order to retrieve an array of ids
var ids = $('.failed').map(function(){
return this.id
}).get();
console.log(ids);
alert(ids)
employ jQuery for every instance
$('.failed').each(function(index){
var id=$(this).attr('id');//retrieve each individual ID
});
Using jQuery's each function to loop through elements with the class "failed" and creating an alert with their respective ID.let identifiers = []; //initialize an empty array
$('.failed').each(function(e)){ //loop through each element
identifiers.push($(this).prop('id')); //add their ID to the array
});
alert(identifiers);
If you loop through the input elements, you can perform any action on those that belong to a specific class:
$("input.failed").each(function() {
console.log($(this).attr('id'));
});
To trigger a notification for all IDs when the button is clicked, you can use this code:
$("#btnid").click(function(){ // Click event on button
$('.failed').each( function () {
alert ($(this).attr('id')); // Display ID one by one in an alert
});
});
