jquery splicing json of ajax and string splicing method

Organize the documents, search out an jquery splicing ajax json and string splicing code, and slightly organize and simplify 1 to share.

jQuery Splice String ajax

<form id="myForm" action="#">
  <input name="name"/>
  <input name="age"/>
  <input type="submit"/>
</form>
<script src="http://cdn.static.runoob.com/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
  (function($){
    $.fn.serializeJson=function(){
      var serializeObj={};
      $(this.serializeArray()).each(function(){
        serializeObj[this.name]=this.value;
      });
      return serializeObj;
    };

    $('#myForm').bind('submit',function(e){
      console.log($(this).serializeJson())
    })
  })(jQuery)

</script>

Or serialize directly with $("# Form id"). serialize (). . .

The above plug-in cannot be applied to input controls with multiple values, such as check boxes, multi-selected select. Next, I will make a step one modification to make it support multiple choices. 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-selected value as a numeric value for processing. If you need to encapsulate the multi-selected values as "," connected strings or other forms, please modify the corresponding code.

The tests are 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 results:

{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($(this).attr("name")+'='+$(this).val());
  }).get().join("&");
  alert(dataId);
  </script>
