What is the best method for gathering information from multiple input fields?

I'm currently working on developing a Polymer application that includes a search button with multiple input boxes. I want the search operation to consider all the inputs from these boxes when performing a search.

Here is an image depicting the scenario -

I am aware of using {iron-form} for this purpose, but I would like to explore new and easier options. Can anyone help me with this?

Since I don't have access to your specific HTML code, I will be using elements that are commonly found within a typical document.

Let's give this a try:

Vanilla JavaScript Approach:

var form = document.getElementsByTagName("form")[0];

form.onsubmit = function(){ // when the form is submitted
    var input = document.querySelectorAll("input");

    for(var i = 0; i < input.length; i++){ // loop through each input element
        alert(input[i].value); // display the value of the input
    }

    return false; // prevent the form from submitting
}

Using jQuery Library:

$("form").submit(function(){ // when the form is submitted
    $("input").each(function(){ // iterate through each input field
        var value = $(this).val(); // retrieve its value

        alert(value); // display the value in an alert box
    });

    return false; // stop the form from submitting
});

With this setup, every time the form is submitted, it will go through each input, displaying their values in separate alerts.

I hope this explanation proves useful! :-)

When utilizing the Polymer tag, there is a dedicated method in Polymer for handling forms called iron-form. While @Caelan's approach is valid, it may not be compatible with Polymer elements or custom elements like paper-input and paper-checkbox. Refer to the Paper Elements page for a comprehensive list of customized inputs.

The <iron-form></iron-form> component provides the convenient methods serialize and validate, ideal for gathering all inputs, including custom elements, with just one function call.

For more details, visit the iron-form.serialize documentation.

var form = document.querySelector('iron-form')

form.onsubmit = function(event) {
    event.preventDefault();
    var data = form.serialize()
    // Handle data accordingly
    // return false; // an alternative to event.preventDefault()
}

Check out the discussion on preventDefault vs return false on Stack Overflow – either method will suffice if event bubbling is unimportant in your scenario.
