In the process of daily development, it is inevitable to use form forms. We need to obtain the form data and save it to the database, or get a string of json data in the background. To bind the data to the form form, here I write I have a formHelp plug-in based on jquery, which is very simple to use:

Get the form data: $("#formid").serializeJson();

Bind data to the form: $("#formid").setForm(json);

jquery.formHelp.js plug-in

/**
 * 将form里面的内容序列化成json
 * 相同的checkbox用分号拼接起来
 * @param {dom} 指定的选择器
 * @param {obj} 需要拼接在后面的json对象
 * @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;
};

/**
 * 将josn对象赋值给form
 * @param {dom} 指定的选择器
 * @param {obj} 需要给form赋值的json对象
 * @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);
    }
  })
}

The above is the entire content of jquery to obtain the form form content and bind data to the form form. I hope it will be helpful to everyone's learning.
