获取原生表单的值

// jq
function getFormValue(dom) {
    var a = dom.serialize().split('&')
    a = decodeURIComponent(a,true)
    var b = {}
    for (let i=0; i< a.length; i++) {
        let k = a[i].split('=')[0]
        let v = a[i].split('=')[1]
        b[k] = v
    }
    return b
}
// 原生
function formser(form){
   var form=document.getElementById(form);
   var arr={};
   for (var i = 0; i < form.elements.length; i++) {
   var feled=form.elements[i];
