# .val()

Categories: Attributes | Forms | Manipulation > General Attributes

## .val() Returns: String, Number, Array

Description: Get the current value of the first element in the set of matched elements.

- #### version added: 1.0.val()

The `.val()` method is primarily used to get the values of form elements such as `input`, `select` and `textarea`. In the case of `<select multiple="multiple">` elements, the `.val()` method returns an array containing each selected option.

For selects and checkboxes, you can also use the :selected and :checked selectors to get at values, for example:

    $('select.foo option:selected').val();    // get the value from a dropdown select
    $('select.foo').val();                    // get the value from a dropdown select even easier
    $('input:checkbox:checked').val();        // get the value from a checked checkbox
    $('input:radio[name=bar]:checked').val(); // get the value from a set of radio buttons

> Note: At present, using `.val()` on textarea elements strips carriage return characters from the browser-reported value. When this value is sent to the server via XHR however, carriage returns are preserved (or added by browsers which do not include them in the raw value). A workaround for this issue can be achieved using a valHook as follows:

    $.valHooks.textarea = {
        get: function( elem ) {
            return elem.value.replace( /\r?\n/g, "\r\n" );
        }
    };

### Examples:

#### Example: Get the single value from a single select and an array of values from a multiple select and display their values.

      <select id="multiple" multiple="multiple">
        <option selected="selected">Multiple</option>
        <option>Multiple2</option>
        <option selected="selected">Multiple3</option>
      </select>

    <script>
        function displayVals() {
          var singleValues = $("#single").val();
          var multipleValues = $("#multiple").val() || [];
          $("p").html("<b>Single:</b> " +
                      singleValues +
                      " <b>Multiple:</b> " +
                      multipleValues.join(", "));
        }

        $("select").change(displayVals);
        displayVals();

#### Demo:

#### Example: Find the value of an input box.

    <!DOCTYPE html>
    <html>
    <head>
      <style>

      p { color:blue; margin:8px; }
      </style>
      <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
    </head>
    <body>
      <input type="text" value="some text"/>
      <p></p>
    <script>
        $("input").keyup(function () {
          var value = $(this).val();
          $("p").text(value);
        }).keyup();
    </script>

    </body>
    </html>

#### Demo:

## .val( value ) Returns: jQuery

Description: Set the value of each element in the set of matched elements.

- #### version added: 1.0.val( value )

  valueA string of text or an array of strings corresponding to the value of each matched element to set as selected/checked.

- #### version added: 1.4.val( function(index, value) )

  function(index, value)A function returning the value to set. `this` is the current element. Receives the index position of the element in the set and the old value as arguments.

This method is typically used to set the values of form fields.

Passing an array of element values allows matching `<input type="checkbox">`, `<input type="radio">` and `<option>`s inside of n `<select multiple="multiple">` to be selected. In the case of `<input type="radio">`s that are part of a radio group and `<select multiple="multiple">` the other elements will be deselected.

The `.val()` method allows us to set the value by passing in a function. As of jQuery 1.4, the function is passed two arguments, the current element's index and its current value:

    $('input:text.items').val(function( index, value ) {
      return value + ' ' + this.className;
    });

This example appends the string " items" to the text inputs' values.
