js dynamically creates objects, properties dynamically create

 

jQuery gets the form fields nicely and can then create objects containing the form fields,

 

 

var data = {"timeFlag":new Date()}; //Create an object

        var formDataStr = jQuery("#formGeneWholeModalQuery").serialize();//formGeneWholeModalQuery is the id of the form, and formDataStr is a string like userName=test&password=3241&age=54

        var fmArr = formDataStr.split("&");
        for(var i=0;i<fmArr.length;i++)
        {
            var fmF = fmArr[i];
            var fmFarr = fmF.split("=");
            var key = fmFarr[0];
            if(!isNullOrEmpty(fmFarr[1]))
            {
                eval("data."+key+"="+fmFarr[1]+";");//Write data.key directly, this is equivalent to data having a key attribute, you need to call eval to dynamically assign attributes
            }

        }

        data.queryType = type;

//data already contains the value of each object

function isNullOrEmpty(field)
{
	if(typeof field == undefined || typeof field == "undefined")
		return true;
	if(null==field || jQuery.trim(field).length<1)
		return true;
	return false;
}
