Implement a simple instance of a form form through Ajax without refreshing submission _jquery

Examples are as follows:

Convert form to Ajax commit
  function Ajaxsubmit (URL,FRM,FN) {
    var datapara=getformjson (frm);
    $.ajax ({
      url:url,
      type: "Post",
      Data:datapara,
      async:false,
      dataType: ' txt ',
      success: fn
    });
  Converts a value in a form to a key value pair
  function Getformjson (frm) {
    var o={};
    var a=$ (frm). Serializearray ();
    $.each (A,function () {
      if (o[this.name]!==undefined) {
        if (!o[this.name].push) {
          o[this.name]=[o[ THIS.name]];
        }
        O[this.name].push (This.value | | '');
      } else{
        O[this.name]=this.value | | '';
      }
    });
    return o;
  }

//
  /Foreground call mode
  function Autosubmitfun () {
     ajaxsubmit ("Autosumitscoreajax.action", $ (' #formId '), function () {});
*/

The above is a small set for everyone to bring the form form through Ajax to achieve no refreshing submission of a simple example of all the content, I hope that we support cloud Habitat Community ~
