我使用javascript成功创建了此模板:
我在async
函数中创建模板:
this.createBoxes = async function() {
var row_counter = 0;
for (var i = 1; i < this.fake_data.length + 1; i++) {
var item_box = document.createElement("div");
item_box.style.flex = "0.5";
item_box.style.backgroundColor = "white";
item_box.style.display = "flex";
item_box.style.flexDirection = "column";
item_box.style.justifyContent = "flex-end";
item_box.id = "item_box_"+i;
var item_name = document.createElement("h3");
item_name.style.flex = "0.2";
item_name.style.backgroundColor = "orange";
item_name.style.alignSelf = "center";
item_name.innerText = this.fake_data[i - 1].name;
item_name.id = "item_name_"+i;
item_box.appendChild(item_name);
this_row = document.getElementsByClassName("row")[row_counter];
this_row.appendChild(item_box);
if(i % 2 == 0) {
var pool = document.getElementById("pool");
var inner_row = document.createElement("div");
inner_row.style.display = "flex";
inner_row.style.flexDirection = "row";
inner_row.style.flex = "0.5";
inner_row.style.justifyContent = "space-around";
inner_row.style.alignItems = "center";
inner_row.style.backgroundColor = "green";
inner_row.className = "row";
pool.appendChild(inner_row);
row_counter++;
}
else if(i == this.fake_data.length) {
return;
}
}
}
然后我这样做:
this.createBoxes().then(function() {
var template = document.querySelector('#pool');
var clone = template.content.cloneNode(true);
document.querySelector(".app").appendChild(clone);
})
但是,正如您从我的屏幕截图中看到的那样,.app
是空的。我究竟做错了什么?我使用的是Cordova,我假设它可以使用template
标签,但我找不到任何不能的东西。
更新
发生这种情况:
当我这样做时:
this.createBoxes().then(function() {
var template = document.querySelector('#pool');
var clone = template.cloneNode(true);
document.querySelector(".app").appendChild(clone);
});
使用template.cloneNode成功移动<template>
,但这显然不是我想要的,我想获取<template>
的内容并将其移动到.app
容器,而不是整个<template>
。

好吧,如果克隆节点本身可以工作,那么答案就很简单-只需克隆/附加模板的子代:
public class Object {
@ElementCollection(fetch = FetchType.EAGER)
@CollectionTable(name = "object_translation",
foreignKey = @ForeignKey(value = ConstraintMode.CONSTRAINT, name = "fk_object_translation_object"),
joinColumns = @JoinColumn(name = "object_id"))
@MapKeyColumn(name = "language", nullable = false)
@MapKeyEnumerated(EnumType.STRING)
@Column(name = "translation", nullable = false)
private Map<Language, String> translations;
}
请注意,我尚未测试此代码-您可能需要根据需要对其进行调试。

我以编程方式向模板添加了一个容器:
var pool = document.getElementById("pool");
var container = document.createElement("div");
container.style.flex = "1";
container.style.backgroundColor = "white";
container.style.display = "flex";
container.style.flexDirection = "column";
container.id = "container";
var row = document.createElement("div");
row.style.display = "flex";
row.style.flexDirection = "row";
row.style.flex = "0.5";
row.style.justifyContent = "space-around";
row.style.alignItems = "center";
row.style.backgroundColor = "green";
row.className = "row";
container.appendChild(row);
pool.appendChild(container);
然后,我没有将我的内容添加到#pool
<template>
,而是将其添加到#container
,然后将#container
节点存储在变量中,然后将其导入放入.app
:
var container_in_temp = document.querySelector('#pool>#container');
var targetContainer = document.querySelector('.app');
targetContainer.appendChild(document.importNode(container_in_temp, true));
因此最终看起来像这样,.app
中有一个容器,实际上这是一种更可取的结构:)。

您应该克隆模板的 .content
,如 the documentation 中所示。
var temp = document.getElementsByTagName("template")[0];
var clon = temp.content.cloneNode(true);
document.body.appendChild(clon);
