【前端】将form数据转化为json再提交

(function($) {
    $.fn.serializeJson = function() {
        var serializeObj = {};
        var array = this.serializeArray();
        var str = this.serialize();
        $(array).each(
                function() {
                    if (serializeObj[this.name]) {
                        if ($.isArray(serializeObj[this.name])) {
                            serializeObj[this.name].push(this.value);
                        } else {
                            serializeObj[this.name] = [
                                    serializeObj[this.name], this.value ];
                        }
                    } else {
                        // 如果表单的数据值是空，将其从序列化的数据中锡除
                        if (!(this.value == "")) {
                            serializeObj[this.name] = this.value;
                        }
