如何根据数组中的对象数创建按钮？

Question

I have an array with 3 objects

map.la = [object, object, object];

I want to create a button for each of these objects. The reason i have to dybamicaly create the buttons is because the number of objects varies from time to time.

How can i loop through each object and create a button for it and then set the tooltip of the button to equal the name property inside each object?

the button:

this._selectionbutt = new SegButton({
    items: [

        //each of the below items (this.selection) should be added here to items array. because we have 3 buttons there
        //should be three unique items here. the items should have the same name as the variable we instantiate the
        //button with.

        this._oSelection
    ]
});

this.selection = new SegButtItems({
    icon: "map",
    tooltip: //this should be the name property of each item
    press: this._handleSelection();
});

Once the user selects the button any of the buttons they will be taken to the same function (this._handleSelection()) and this function will need to check the name property string eg "map333" and thats it.

Any guidance will be highly appreicated :)

Thank you

Here is a simple example:

HTML code. Create div, to wich we will add buttons

<div id="buttons"></div>

Js code:

//create objects

var Object1 = {
    icon: "map",
    tooltip: "Press Me",
    press: 'console.log("Button1 pressed")'
};
var Object2 = {
    icon: "map",
    tooltip: "Press Me",
    press: 'console.log("Button2 pressed")'
};
var Object3 = {
    icon: "map",
    tooltip: "Press Me",
    press: 'console.log("Button3 pressed")'
};

//add objects to array
var ar = [Object1, Object2, Object3];
//add buttons for every object in array
ar.forEach( function(v) { 
    var button= document.createElement('button');
    button.type= 'button';
    button.appendChild(document.createTextNode(v.tooltip));
    button.setAttribute('onClick',v.press);
  document.getElementById("buttons").appendChild(button);
 } );
