您是否曾经想过拥有一个HTML的可拖放排序表格,可对行和列进行排序?我知道这是我为之奋斗的。现在有很多可排序的列表,但似乎找不到可排序的表格。
我知道使用script.aculo.us提供的工具可以接近实现,但我遇到了一些跨浏览器的问题。

我已经成功地使用了jQuery UI的sortable插件。标记类似于这样:
<table id="myTable">
<thead>
<tr><th>ID</th><th>Name</th><th>Details</th></tr>
</thead>
<tbody class="sort">
<tr id="1"><td>1</td><td>Name1</td><td>Details1</td></tr>
<tr id="2"><td>2</td><td>Name1</td><td>Details2</td></tr>
<tr id="3"><td>3</td><td>Name1</td><td>Details3</td></tr>
<tr id="4"><td>4</td><td>Name1</td><td>Details4</td></tr>
</tbody>
</table>
然后在JavaScript中执行
$('.sort').sortable({
cursor: 'move',
axis: 'y',
update: function(e, ui) {
href = '/myReorderFunctionURL/';
$(this).sortable("refresh");
sorted = $(this).sortable("serialize", 'id');
$.ajax({
type: 'POST',
url: href,
data: sorted,
success: function(msg) {
//do something with the sorted data
}
});
}
});
这将会把项的ID序列化后POST到给定的URL。接下来,该函数(在我的情况下是PHP)会在数据库中更新这些项的顺序。
对我来说,David Heggie的回答最有用。可以稍微简洁一些:
var sort = function(event, ui) {
var url = "/myReorderFunctionURL/" + $(this).sortable('serialize');
$.post(url, null,null,"script"); // sortable("refresh") is automatic
}
$(".sort").sortable({
cursor: 'move',
axis: 'y',
stop: sort
});
对我来说有效,使用相同的标记。
大多数框架(Yui、MooTools、jQuery、Prototype/Scriptaculous等)都具有可排序列表功能。对每个框架进行一些研究,选择最适合您需求的那一个。
如果在David Heggie的解决方案中,您发现.serialize()返回空值,请将TRs的id值设置为'id_1'而不是简单地'1'
例如:
<tr id="id_1"><td>1</td><td>Name1</td><td>Details1</td></tr>
<tr id="id_2"><td>2</td><td>Name1</td><td>Details2</td></tr>
<tr id="id_3"><td>3</td><td>Name1</td><td>Details3</td></tr>
<tr id="id_4"><td>4</td><td>Name1</td><td>Details4</td></tr>
以上将被序列化为"id[]=1&id[]=2&id[]=3"
您可以使用'=','-'或'_'代替'_'。 除了"id"之外的任何其他单词。
如果您不介意Java,有一个非常方便的GWT库称为 GWT-DND ,请查看在线演示,了解其强大之处。
我正在使用JQuery Sortable来实现这一点,但是如果您像我一样使用Vue.js,那么这里有一个解决方案,它创建了一个自定义的Vue指令来封装Sortable功能。我知道Vue draggable,但它不能按照问题HERE对表格列进行排序。要查看此操作,请CHECK THIS
JS代码
Vue.directive("draggable", {
//adapted from https://codepen.io/kminek/pen/pEdmoo
inserted: function(el, binding, a) {
Sortable.create(el, {
draggable: ".draggable",
onEnd: function(e) {
/* vnode.context is the context vue instance: "This is not documented as it's not encouraged to manipulate the vm from directives in Vue 2.0 - instead, directives should be used for low-level DOM manipulation, and higher-level stuff should be solved with components instead. But you can do this if some usecase needs this. */
// fixme: can this be reworked to use a component?

// https://github.com/vuejs/vue/issues/2873 "directive interface change"
// `binding.expression` should be the name of your array from vm.data
// set the expression like v-draggable="items"
var clonedItems = a.context[binding.expression].filter(function(item) {
return item;
});
clonedItems.splice(e.newIndex, 0, clonedItems.splice(e.oldIndex, 1)[0]);
a.context[binding.expression] = [];
Vue.nextTick(function() {
a.context[binding.expression] = clonedItems;
});
}
});
}
});
const cols = [
{name: "One", id: "one", canMove: false},
{name: "Two", id: "two", canMove: true},
{name: "Three", id: "three", canMove: true},
{name: "Four", id: "four", canMove: true},
]
const rows = [
{one: "Hi there", two: "I am so excited to test", three: "this column that actually drags and replaces", four: "another column in its place only if both can move"},
{one: "Hi", two: "I", three: "am", four: "two"},
{one: "Hi", two: "I", three: "am", four: "three"},
{one: "Hi", two: "I", three: "am", four: "four"},
{one: "Hi", two: "I", three: "am", four: "five"},
{one: "Hi", two: "I", three: "am", four: "six"},
{one: "Hi", two: "I", three: "am", four: "seven"}
]
Vue.component("datatable", {
template: "#datatable",
data() {
return {
cols: cols,
rows: rows
}
}
})
new Vue({
el: "#app"
})
CSS
.draggable {
cursor: move;
}
table.table tbody td {
white-space: nowrap;
}
Pug模板HTML
#app
datatable
script(type="text/x-template" id="datatable")
table.table
thead(v-draggable="cols")
template(v-for="c in cols")
th(:class="{draggable: c.canMove}")
b-dropdown#ddown1.m-md-2(:text='c.name')
b-dropdown-item First Action
b-dropdown-item Second Action
b-dropdown-item Third Action
b-dropdown-divider
b-dropdown-item Something else here...
b-dropdown-item(disabled='') Disabled action
tbody

tr
template(v-for="(col, index) in cols")
td {{row[col.id]}}
那么sorttable怎么样?它似乎很适合您的要求。
使用起来相当简单-加载sorttable Javascript文件,然后对于每个要使其可排序的表格,将class ="sortable"应用于<table>标记。
它会立即了解如何对大多数类型的数据进行排序,但如果有某些数据它不了解,您可以添加自定义排序键以告诉它如何排序。文档解释得非常清楚。
serialize
调用返回null。当我更改ID,如Lathan在这里的答案所述时,它可以工作。不确定它是否与[tag:jquery]的版本相关。 - Hobo
