serializearray

问题 I have this HTML: <form id='myform'> <input name='title' value='foo'/> </form> And I create an object array from it like this: var dataArray = $("#myform").serializeArray(); Now how do I access 'title' in dataArray?

问题 I'm trying to use JQuery's serializeArray method to create an array of objects from a simple form (get data from a form and cache to be use later): <fieldset class="myFieldset"> <div id="divContainer"> <div class="anotherdiv"> <input type="text" name="testBox1" class="aclass" /> <select name="testSel1" class="atestclass"> <option value="car">car</option> <option value="boat">boat</option> <option value="plane">plane</option> </select> </input> </div> </div> </fieldset> <fieldset class="submit
