在使用FastAdmin 键值组件(Fieldlist) 如果键名为纯数字时，保存后排序失败，将变成键名由小到大的排列方式，用起来很不方便
可以自己修改 public/assets/js/require-form.js 文件，将里面的 fieldlist 替换成下面的，只修改了加粗部分，直接替换会方便些
fieldlist: function (form) {
//绑定fieldlist
if ($(".fieldlist", form).length > 0) {
require(['dragsort', 'template'], function (undefined, Template) {
var prefix='~*orderByKey*~';
//刷新隐藏textarea的值
var refresh = function (container) {
var data = {};
var name = container.data("name");
var textarea = $("textarea[name='" + name + "']", form);
var template = container.data("template");
$.each($("input,select,textarea", container).serializeArray(), function (i, j) {
var reg = /\[(\w+)\]\[(\w+)\]$/g;
var match = reg.exec(j.name);
if (!match)
return true;
match[1] = "x" + parseInt(match[1]);
if (typeof data[match[1]] == 'undefined') {
data[match[1]] = {};
}
data[match[1]][match[2]] = j.value;
});
var result = template ? [] : {};
$.each(data, function (i, j) {
if (j) {
if (!template) {
if (j.key != '') {
result[prefix + j.key] = j.value;
}
} else {
result.push(j);
}
}
});
textarea.val(JSON.stringify(result).replaceAll(prefix,''));
};
//追加一行数据
var append = function (container, row, initial) {
var tagName = container.data("tag") || (container.is("table") ? "tr" : "dd");
var index = container.data("index");
var name = container.data("name");
var template = container.data("template");
var data = container.data();

var html = template ? Template(template, vars) : Template.render(Form.config.fieldlisttpl, vars);
