js 将form表单伪造成ajax 提交

<form onsubmit="return concatFormDataToUri(this,hh)">
        <input  name="name" text="233223">
        <input  name="name" text="233223">
        <select name="232323"><option checked="true">4444444</option><option >2332232323</option></select>
        <input type="submit" value="提交">
</form>

    var concatFormDataToUri = function(_this,_function){
        $_inputs = $(_this).find(":input");
        var _uri = "";
        $.each($_inputs,function(){
            //如果是select对象
            if(this instanceof HTMLSelectElement){
                _uri +="&"+this.name+"="+$(this).find(":checked").val();
            }else if(this instanceof HTMLInputElement && this.type!="submit" && this.type!="reset"){
                //input对象
                _uri +="&"+this.name+"="+this.value;
            }
            _uri = _uri.substring(1,_uri.length)
        })
        this.formDataUrl=_uri;
        _function();
        return false;
    }
    
    function hh(){
        alert(formDataUrl);
    }

结果：
