数据验证:在columns中设置validator,进行同步或异步验证,还可添加beforeValidate, afterValidate函数,allowInvalid:true可以不用验证
var people = [
{id: 1, name: {first: 'Joe', last: 'Fabiano'}, ip: '0.0.0.1', email: 'Joe.Fabiano@ex.com'},

往下拖
var
data = [
['', 'Kia', 'Nissan', 'Toyota', 'Honda'],
['2012', 10, 11, 12, 13],
['2013', 20, 11, 14, 13],
['2014', 30, 15, 12, 13],
['2015', '', '', '', ''],
['2016', '', '', '', '']
],
container = document.getElementById('example1'),
hot1; hot1 = new Handsontable(container, {
rowHeaders: true,
colHeaders: true,
//默认为true,如果为"horizontal",则只能水平拖动
fillHandle: true // possible values: true, false, "horizontal", "vertical"
});
hot1.loadData(data);
合并单元格
var
container = document.getElementById('example1'),
hot; hot = new Handsontable(container, {
data: Handsontable.helper.createSpreadsheetData(100, 18),
colWidths: [47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47],
rowHeaders: true,
colHeaders: true,
contextMenu: true,
//使用mergeCells提供合并单元格的细节
mergeCells: [
{row: 1, col: 1, rowspan: 3, colspan: 3},
{row: 3, col: 4, rowspan: 2, colspan: 2},
{row: 5, col: 6, rowspan: 3, colspan: 3}
]
});
布局:在cell中设置位置;水平方向:htLeft, htCenter, htRight, htJustify;垂直方向:htTop, htMiddle, htBottom
var
container = document.getElementById('example1'),
hot1; hot1 = new Handsontable(container, {
data: Handsontable.helper.createSpreadsheetData(100, 18),
colWidths: [47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47],
rowHeaders: true,
colHeaders: true,
contextMenu: true,
mergeCells: [
{row: 1, col: 1, rowspan: 3, colspan: 3},
{row: 3, col: 4, rowspan: 2, colspan: 2}
],
//预定义了很多类
className: "htCenter",
cell: [
{row: 0, col: 0, className: "htRight"},
{row: 1, col: 1, className: "htLeft htMiddle"},
{row: 3, col: 4, className: "htLeft htBottom"}
],
//在这个hooks中,可以捕获到布局的改变
afterSetCellMeta: function (row, col, key, val) {
console.log("cell meta changed", row, col, key, val);
}
});
列和单元格的只读属性
var
container1 = document.getElementById('example1'),
hot1; hot1 = new Handsontable(container1, {
data: getCarData(),
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'],
columns: [
{
data: 'car',
//列只读
readOnly: true
},
{
data: 'year'
},
{
data: 'chassis'
},
{
data: 'bumper'
}
]
});
//单元格只读
var
container2 = document.getElementById('example2'),
hot2; hot2 = new Handsontable(container2, {
data: getCarData(),
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'] });
hot2.updateSettings({
cells: function (row, col, prop) {
var cellProperties = {}; if (hot2.getData()[row][prop] === 'Nissan') {
cellProperties.readOnly = true;
} return cellProperties;
}
})
列和单元格不可编辑:non-edit cell仍然可以拖动填充,复制粘贴,只是不能编辑;只读属性:不能做任何操作
var
container1 = document.getElementById('example1'),
hot1; hot1 = new Handsontable(container1, {
data: getCarData(),
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'],
columns: [
{
data: 'car',
editor: false
},
{
data: 'year',
editor: 'numeric'
},
{
data: 'chassis',
editor: 'text'
},
{
data: 'bumper',
editor: 'text'
}
]
});
var
container2 = document.getElementById('example2'),
hot2; hot2 = new Handsontable(container2, {
data: getCarData(),
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color']
});
hot2.updateSettings({
cells: function (row, col, prop) {
var cellProperties = {}; if (hot2.getData()[row][prop] === 'Nissan') {
cellProperties.editor = false;
} else {
cellProperties.editor = 'text';
} return cellProperties;
}
})
