Cell | Features | SpreadJS JavaScript Demos

You can create a cell binding source, and then use the setBindingPath method to set the binding path for cell-level binding in a specified cell in the specified sheet area. Then set the data source for the sheet. For example: You can use getBindingPath to get the binding path of cell-level binding from the specified cell in the specified sheet area.

var person, sheet;
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets;
sheet = spread.sheets[0];
sheet.suspendPaint();
sheet.setColumnWidth(0, 120);
sheet.setColumnWidth(1, 120);
sheet.setColumnWidth(2, 120);
sheet.setValue(0, 0, 'cell-binding');
sheet.setValue(2, 1, 'Name');
sheet.setValue(3, 1, 'Age');
sheet.setValue(4, 1, 'Sex');
sheet.setValue(5, 1, 'Address.postcode');
person = { name: "Wang Feng", age: 25, sex: "Male", address: { postcode: "710075" } };
document.getElementById("personName").value=person.name || "";
document.getElementById("personAge").value=person.age || "";
document.getElementById("personSex").value=person.sex || "";
document.getElementById("personPostcode").value=person.address.postcode || "";
var source = new spreadNS.Bindings.CellBindingSource(person);
sheet.setBindingPath(2, 2, "name");
sheet.setBindingPath(3, 2, "age");
sheet.setBindingPath(4, 2, "sex");
sheet.setBindingPath(5, 2, "address.postcode");
sheet.setDataSource(source);
sheet.setSelection(2, 2, 1, 1);
var path = sheet.getBindingPath(2, 2);
sheet.getRange(2, 2, 4, 1).backColor("rgb(208,206,206)");
document.getElementById("bindingPath").innerHTML=path || "";
sheet.bind(spreadNS.Events.SelectionChanged, function() {
var activeCell = sheet.getSelections()[0];
var path = sheet.getBindingPath(activeCell.row, activeCell.col);
document.getElementById("bindingPath").innerHTML=path || "";
});
sheet.bind(spreadNS.Events.CellChanged, function() {
document.getElementById("personName").value=person.name || "";
document.getElementById("personAge").value=person.age || "";
document.getElementById("personSex").value=person.sex || "";
document.getElementById("personPostcode").value=person.address.postcode || "";
});
sheet.resumePaint();
};
// These functions change the Person object that Spread is bound to
var updateName = function(value) {
if (person && sheet) {
person.name = value;
sheet.repaint();
}
};
var updateAge = function(value) {
if (person && sheet) {
person.age = value;
sheet.repaint();
}
};
var updateSex = function(value) {
if (person && sheet) {
person.sex = value;
sheet.repaint();
}
};
var updatePostcode = function(value) {
if (person && sheet) {
person.address.postcode = value;
sheet.repaint();
}
};
