function serialize(form) { var parts = [], elems = form.elements, i = 0, len = elems.length, filed = null; for (; i < len; i++) { filed = elems[i]; switch (filed.type) { case "select-one": case "select-multiple": if (filed.name.length) { var j = 0, opt, optLen = filed.options.length; for (; j < optLen; j++) { opt = filed.options[j]; if (opt.selected) { parts.push(encodeURIComponent(filed.name) + "=" + encodeURIComponent(opt.value)); } } } break; case undefined: case "submit": case "reset": case "file": case "button": break; case "radio": case "checkbox": if (!filed.checked) { break; } default: if (filed.name.length && filed.value) { parts.push(encodeURIComponent(filed.name) + "=" + encodeURIComponent(filed.value)); } } } return parts.join("&"); }
这个方法重点用了HTML5中的FormData ,还有es6中for of循环。
function serialize(form) { var formData = new FormData(form), getValue = formData.entries(), parts = []; for (var pair of getValue) { parts.push(pair[0] + "=" + pair[1]); } return parts.join("&"); }
