如何将初始化数据发送到 Mithril 组件
How can I send init data to a Mithril component
我正在尝试通过设置 ID 来初始化 Mithril 组件以从服务器获取数据,如下所示:
// view/UserList.js
module.exports = {
oninit: function(vnode) {
console.log(vnode);
var groupId = vnode.attrs.groupId;
console.log('The group ID is '+groupId);
User.loadUsersInGroup(groupId);
},
view: ...
}
我有以下内容:
var userList = require('./view/UserList');
m.mount(document.body, UserList, {groupId: 5});
但我得到:
vnode.attrs is undefined
我尝试将其更改为:
var UserList = require('./view/UserList');
m.mount(document.body, m(UserList, {groupId: 5}));
但现在我得到:
m.mount(element, component) expects a component, not a vnode
如何才能正确填充 vnode.attrs?
可以在 https://mithril.js.org/mount.html#description.
中找到向组件发送初始化数据的正确方法
To pass arguments when mounting a component use:
m.mount(element, {view: function () {return m(Component, attrs)}})
因此应用于这种情况,它将是:
m.mount(document.body, {view: function() { return m(UserList, {groupId: 5}); }});
其他一些方法是:
const full = {view: vnode => m('h1', vnode.attrs.test)}
const short = {view: v => m('h1', v.attrs.test)}
const dest = {view: ({attrs}) => m('h1', attrs.test)}
const destf = {view: ({attrs: {test}}) => m('h1', test)}
m.mount(document.body, {
view: () => [
m(full, {test: "full"}),
m(short, {test: "short"}),
m(dest, {test: "destructured"}),
m(destf, {test: "fully destructured"})
]
})
