我正在使用select2编辑器的动手,但我似乎无法使用下拉菜单使用动态选项,即在动手初始化时设置的选项是似乎只显示的唯一选项。
我尝试使用全局变量作为选项的来源,并在我的代码中的各个点更新它,并使用函数返回相同的变量,但这两个尝试似乎都没有。
e.g。
var hot;
var data = [];
function customDropdownRenderer(instance, td, row, col, prop, value, cellProperties) {
if (instance.getCell(row, col)) {
$(instance.getCell(row,col)).addClass('select2dropdown');
}
var selectedId;
var colOptions = cellProperties.select2Options.data;
if (colOptions != undefined) {
for (var index = 0; index < colOptions.length; index++) {
if (parseInt(value) === colOptions[index].id) {
selectedId = colOptions[index].id;
value = colOptions[index].text;
}
}
Handsontable.TextCell.renderer.apply(this, arguments);
}
}
var requiredText = /([^\s])/;
$(document).ready(function(){
var
$container = $("#example1"),
$parent = $container.parent(),
autosaveNotification;
hot = new Handsontable($container[0], {
columnSorting: true,
stretchH: 'all',
startRows: 8,
startCols: 5,
rowHeaders: true,
colHeaders: ['Description', 'Cost', 'Remarks'],
columns: [
{ data: 'description' },
{
data: 'cost',
editor: 'select2',
renderer: customDropdownRenderer,
select2Options: { data: getData(), dropdownAutoWidth: true }
},
{ data: 'remarks' },
],
minSpareCols: 0,
minSpareRows: 1,
contextMenu: true,
data: []
});
data = [{id:'fixed',text:'Fixed'},{id:'variable',text:'Variable'}];
});
function getData() {
return data;
}

您已多次定义数据并导致争用。
以下更改将解决此问题:
在.ready()函数后立即定义以下内容:
var source = [{id:'fixed',text:'Fixed'},{id:'variable',text:'Variable'}];
并将select2Options更新为以下内容:
select2Options:{data:source,dropdownAutoWidth:true}

我设法通过重新使用我用来解决xeditable插件相同问题的一些代码来实现它。
这是更新后的代码:
var hot;
var data = [];
function customDropdownRenderer(instance, td, row, col, prop, value, cellProperties) {
if (instance.getCell(row, col)) {
$(instance.getCell(row,col)).addClass('select2dropdown');
}
var selectedId;
var colOptions = cellProperties.select2Options.data;
if (colOptions != undefined) {
for (var index = 0; index < colOptions.length; index++) {
if (parseInt(value) === colOptions[index].id) {
selectedId = colOptions[index].id;
value = colOptions[index].text;
}
}
Handsontable.TextCell.renderer.apply(this, arguments);
}
}
var requiredText = /([^\s])/;
$(document).ready(function(){
var
$container = $("#example1"),
$parent = $container.parent(),
autosaveNotification;
hot = new Handsontable($container[0], {
columnSorting: true,
stretchH: 'all',
startRows: 8,
startCols: 5,
rowHeaders: true,
colHeaders: ['Description', 'Cost', 'Remarks'],
columns: [
{ data: 'description' },
{
data: 'cost',
editor: 'select2',
renderer: customDropdownRenderer,
// select2Options: { data: getData(), dropdownAutoWidth: true }
select2Options: { data: getSource(), dropdownAutoWidth: true, width: 'resolve', initSelection: getInitSel(false), query: getQuery }
},
{ data: 'remarks' },
],
minSpareCols: 0,
minSpareRows: 1,
contextMenu: true,
data: []
});
data = [{id:'fixed',text:'Fixed'},{id:'variable',text:'Variable'}];
});
/*
function getData() {
return data;
}
*/
// New Code
function getSource() {
return data;
};
function getQuery(options) {
options.callback({ results : getSource() });
};
function getInitSel(multiple) {
return function(el, cb) {
var t, toSet = [], sc = getSource();
el[0].value.split(',').forEach(function(a) {
for (var i = 0; i < sc.length; i++) {
if (sc[i].id == Number(a.trim())) {
t = sc[i];
}
}
// or, if you are using underscore.js
// t = _.findWhere(sc, { id : Number(a.trim()) });
if(t) toSet.push(t);
});
cb(multiple ? toSet : (toSet.length ? toSet[0] : null));
};
};
