我遇到了与aldeed:tabular
的问题#53相同的问题。当按照文档中的建议定义表时,调用转换函数(TAPi18n.__
或其他)还为时过早,因为 I18N 变量尚未设置。
翻译的专栏标题输入DataTables
的好方法是什么,无论是直接按照 aldeed 本人在关闭问题时的建议,还是通过aldeed:tabular
?
with .tabular.options
有一种方法可以让模板的.tabular.options
反应式可变的,但它很古怪。这是库的变体示例使用tap-i18n 翻译列标题:
function __(key) {
if (Meteor.isServer) {
return key;
} else {
return TAPi18n.__(key);
}
}
Books = new Meteor.Collection("Books");
TabularTables = {};
TabularTables.Books = new Tabular.Table({
name: "Books",
collection: Books,
columns: [] // Initially empty, reactively updated below
});
var getTranslatedColumns = function() {
return [
{data: "title", title: __("Title")},
{data: "author", title: __("Author")},
{data: "copies", title: __("Copies Available")},
{
data: "lastCheckedOut",
title: __("Last Checkout"),
render: function (val, type, doc) {
if (val instanceof Date) {
return moment(val).calendar();
} else {
return "Never";
}
}
},
{data: "summary", title: __("Summary")},
{
tmpl: Meteor.isClient && Template.bookCheckOutCell
}
];
}
if (Meteor.isClient) {
Template.tabular.onRendered(function() {
var self = this;
self.autorun(function() {
var options = _.clone(self.tabular.options.get());
options.columns = getTranslatedColumns();
self.tabular.options.set(_.clone(options));
});
});
}
使用分叉版本
我针对meteor-tabular
的分支devel
创建了一个拉取请求,以实现基于响应式的简单方法,如下所示:
<template name="MyTemplateWithATable">
{{> tabular table=makeTable class="table table-editable table-striped table-bordered table-condensed"}}
</template>
var MyColumns = ["title", "author"];
// Assume translations are set up for "MyTable.column.title", "MyTable.column.author"
// in other source files; see TAPi18n documentation for how to do that
function makeTable() {
return new Tabular.Table({
name: "MyTable",
collection: MyCollection,
columns: _.map(MyColumns,
function(colSymbol) {
return {
data: colSymbol,
title: TAPi18n.__("MyTable.column." + colSymbol)
};
})
});
}
if (Meteor.isServer) {
// Called only once
makeTable();
} else if (Meteor.isClient) {
// Reactively called multiple times e.g. when switching languages
Template.MyTemplateWithATable.helpers({makeTable: makeTable});
}
aldeed:tabular允许指定用于设置列标题的功能。
import {TAPi18n} from 'meteor/tap:i18n';
TabularTables = {};
TabularTables.Departments= new Tabular.Table({
name: 'Departments',
collection: Departments,
responsive: true,
autoWidth: true,
stateSave: false,
columns: [
{data: "name", titleFn: function() {
return TAPi18n.__("name");
}},
{data: "description", titleFn: function() {
return TAPi18n.__("description");
}}
]
});
语言更改是被动的。如果您有翻译,您可以切换,列将被翻译。
TAPi18n.setLanguage("en");
TAPi18n.setLanguage("de");
警告词:当您在表数据中包含不可见列时,这目前不起作用。偏移量错误,并且您得到错误的列标题。
