JS工具集-表单自动赋值

$.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(/ /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() == "" ? " " : $this.val();
                if (!$.request("keyValue")) {
                    value = value.replace(/ /g, '');
                }
                postdata[id] = value;
                break;
        }
    });
   
    return postdata;
};

使用： $("#form1").formSerialize(data); 关于表单重复提交问题，可以参考Nfine代码
