JS form表单采集

做后台系统的时候通常会用到form表单来做数据采集；每次一个字段一个字段的去收集就会很麻烦，网站也有form.js插件可以进行表单收集，并封装成一个对象，通过ajax方法传到后台；现在介绍一种直觉采集form表单的方式：

1.首先写一段公用的js：

//收集表单数据为一个数组
$.request = function (name) {
    var search = location.search.slice(1);
    var arr = search.split("&");
    for (var i = 0; i < arr.length; i++) {
        var ar = arr[i].split("=");
        if (ar[0] == name) {
            if (unescape(ar[1]) == ‘undefined‘) {
                return "";
            } else {
                return unescape(ar[1]);
            }
        }
    }
    return "";
}
$.fn.formSerialize = function (formdate) {
    var element = $(this);
    if (!!formdate) {
        for (var key in formdate) {
            var $id = element.find(‘#‘ + key);
            var value = $.trim(formdate[key]).replace(/&nbsp;/g, ‘‘);
            var type = $id.attr(‘type‘);
            if ($id.hasClass("select2-hidden-accessible")) {
                type = "select";
            }
            switch (type) {
                case "checkbox":
                    if (value == "true") {
                        $id.attr("checked", ‘checked‘);
                    } else {
                        $id.removeAttr("checked");
                    }
                    break;
                case "select":
                    $id.val(value).trigger("change");
                    break;
                default:
                    $id.val(value);
                    break;
            }
        };
        return false;
    }
    var postdata = {};
    element.find(‘input,select,textarea‘).each(function (r) {
        var $this = $(this);
        var id = $this.attr(‘id‘);
        var type = $this.attr(‘type‘);
        switch (type) {
            case "checkbox":
                postdata[id] = $this.is(":checked");
                break;
            default:
                var value = $this.val() == "" ? "&nbsp;" : $this.val();
                if (!$.request("keyValue")) {
                    value = value.replace(/&nbsp;/g, ‘‘);
                }
                postdata[id] = value;
                break;
        }
    });
    if ($(‘[name=__RequestVerificationToken]‘).length > 0) {
        postdata["__RequestVerificationToken"] = $(‘[name=__RequestVerificationToken]‘).val();
    }
    return postdata;
};

2.使用方法

 html代码：<form id=‘form1id‘>  姓名：<input type=‘text‘ id=‘names‘ name=‘names‘/><br/>

  年龄：<input type=‘text‘ id=‘names‘ name=‘names‘/></form>

js代码：        var infoModel = JSON.stringify($("#form1id").formSerialize());//得到手机到的表对象        $.ajax({        type: "Post",        url: "/HRSSC/Resume/" + Act,        data: "{infoModel:" + infoModel + "}",//前面的命名和后台接收参数一直        dataType: "json",        contentType: "application/json",        success: function (result) {console.log(result);}

后台代码：public ActionResult AddEmp(Empinfo infoModel)   //命名和前台ajax传的参数一致{//具体业务处理return view();}

只要把form表单里面的字段和后台类字段对应，收集起来的对象在后台可以直接使用！
