:input Selector

Categories: jQuery Extensions | Form

jQuery(':input')

Description: Selects all input, textarea, select and button elements.

  • jQuery(':input')

    version added: 1.0

The :input selector basically selects all form controls.

Note:

Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").
  • Finds all input elements.

    HTML:
    <form>
        <input type="button" value="Input Button"/>
        <input type="checkbox" />
    
        <input type="file" />
        <input type="hidden" />
        <input type="image" />
    
        <input type="password" />
        <input type="radio" />
        <input type="reset" />
    
        <input type="submit" />
        <input type="text" />
        <select><option>Option</option></select>
    
        <textarea></textarea>
        <button>Button</button>
      </form>
      <div id="messages">
      </div>
    CSS:
    
      textarea { height:25px; }
      
    Code:
    
    
        var allInputs = $(":input");
        var formChildren = $("form > *");
        $("#messages").text("Found " + allInputs.length + " inputs and the form has " +
                                 formChildren.length + " children.");
                
        // so it won't submit
        $("form").submit(function () { return false; });
