jquery The form form fetches the content and binds the data

In our daily development process, we will inevitably use the form form, we need to get the form data to save to the database, or get a string of json data in the background, to bind the data to the form form, here I wrote a plug-in based on jquery, formHelp is also easy to use:

$(“#formid”).serializeJson ();

$(“#formid”).setForm(json);

jquery. formHelp. js plug-in

/**
 *  will form The contents are serialized as json
 *  The same checkbox Stitch them together with semicolons
 * @param {dom}  The selector specified
 * @param {obj}  Need to splice in the back json object
 * @method serializeJson
 * */
$.fn.serializeJson=function(otherString){
  var serializeObj={},
    array=this.serializeArray();
  $(array).each(function(){
    if(serializeObj[this.name]){
      serializeObj[this.name]+=';'+this.value;
    }else{
      serializeObj[this.name]=this.value;
    }
  });

  if(otherString!=undefined){
    var otherArray = otherString.split(';');
    $(otherArray).each(function(){
      var otherSplitArray = this.split(':');
      serializeObj[otherSplitArray[0]]=otherSplitArray[1];
    });
  }
  return serializeObj;
};

/**
 *  will josn Object assigned to form
 * @param {dom}  The selector specified
 * @param {obj}  Need to give form The assignment of json object
 * @method serializeJson
 * */
$.fn.setForm = function(jsonValue){
  var obj = this;
  $.each(jsonValue,function(name,ival){
    var $oinput = obj.find("input[name="+name+"]");
    if($oinput.attr("type")=="checkbox"){
      if(ival !== null){
        var checkboxObj = $("[name="+name+"]");
        var checkArray = ival.split(";");
        for(var i=0;i<checkboxObj.length;i++){
          for(var j=0;j<checkArray.length;j++){
            if(checkboxObj[i].value == checkArray[j]){
              checkboxObj[i].click();
            }
          }
        }
      }
    }
    else if($oinput.attr("type")=="radio"){
      $oinput.each(function(){
        var radioObj = $("[name="+name+"]");
        for(var i=0;i<radioObj.length;i++){
          if(radioObj[i].value == ival){
            radioObj[i].click();
          }
        }
      });
    }
    else if($oinput.attr("type")=="textarea"){
      obj.find("[name="+name+"]").html(ival);
    }
    else{
      obj.find("[name="+name+"]").val(ival);
    }
  })
}
