setValue()

sets the value for a Combo control

setValue(ids: (string | number) | (string | number)[]): void;

Parameters:

• ids: (string | number) | (string | number)[] - the ID(s) of options from data collection that should be selected in the control

Example

When the multiselection property of Combo control isn't specified or is set to false, you can set the value of ID as a string, number or array:

const form = new dhx.Form("form_container", {
    rows: [
        {
            name: "combo",
            type: "combo",
            multiselection: false,
            data: [
                { value: "value: 1", id: "id:1" },
                { value: "value: 2", id: "id:2" },
                { value: "value: 3", id: 3 },
                { value: "value: 4", id: 4 },
                { value: "value: 5", id: 5 },
            ]
        },
    ]
});

// selects one option
form.getItem("combo").setValue(4);
// form.getItem("combo").setValue("id_1");
// form.getItem("combo").setValue(["id_1"]);

If multiselection is enabled, you need to pass to the setValue method an array with string/number values of IDs:

const form = new dhx.Form("form_container", {
    rows: [
        {
            name: "combo",
            type: "combo",
            multiselection: true,
            data: [
                { value: "value: 1", id: "id:1" },
                { value: "value: 2", id: "id:2" },
                { value: "value: 3", id: 3 },
                { value: "value: 4", id: 4 },
                { value: "value: 5", id: 5 },
            ]
        },
    ]
});

// selects several options
form.getItem("combo").setValue(["id:1", 4]);
