or directly serializes it using $("#formid").serialize(). . .

The above plug-in cannot be applied to input controls with multiple values, such as check boxes and multi-select selects. Next, I will further modify the plug-in to support multiple selections. The code is as follows:

Js code

(function($){
  $.fn.serializeJson=function(){
    var serializeObj={};
    var array=this.serializeArray();
    var str=this.serialize();
    $(array).each(function(){
      if(serializeObj[this.name]){
        if($.isArray(serializeObj[this.name])){
          serializeObj[this.name].push(this.value);
        }else{
          serializeObj[this.name]=[serializeObj[this.name],this.value];
        }
      }else{
        serializeObj[this.name]=this.value;
      }
    });
    return serializeObj;
  };
})(jQuery);

Here, I encapsulate the multi-select value into a numerical value for processing. If you need to encapsulate the multi-select value into a string connected by "," or other forms when using it, please modify the corresponding code yourself.

The test is as follows:

Form:

Html code

<form id=”myForm” action=”#”>
      <input name=”name”/>
      <input name=”age”/>
      <select multiple=”multiple” name=”interest” size=”2″>
      <option value =”interest1″>interest1</option>
      <option value =”interest2″>interest2</option>
      <option value=”interest3″>interest3</option>
      <option value=”interest4″>interest4</option>
      </select>
      <input type=”checkbox” name=”vehicle” value=”Bike” /> I have a bike
      <input type=”checkbox” name=”vehicle” value=”Car” /> I have a car
      <input type=”submit”/>
      </form>

Test result:

{age: "aa", interest: ["interest2", "interest4"],name: "dd",vehicle:["Bike","Car"]}

<form id="myForm" action="#">
  <input name="name" value="111"/>
  <input name="age" value="2222"/>
  <button type="submit">tijiao</button>
</form>
</body>

<script src="../js/jquery-1.11.0.min.js"></script>
<script>
  var dataId = $("#myForm input").map(function (){
    // return($(this).attr("id"));
    return($(this).attr("name")+&#39;=&#39;+$(this).val());
  }).get().join("&");
  alert(dataId);
  </script>
