how to change object size with inputtext in html5

[NIna12]

I have an object (line) and input text. I want the user can change the size of the object by themself. For example, I'm typing 2 in input text, and the height of the object will be 2 cm. Can anyone tell me the code? 

Fyi: my document type is HTML5

Thanks in advance

Sorry I'm not good in English. Hope you can understand my question

if your textinput has instance name ti and your line is line_mc, you can scale it using the ti's value:

if(!this.ti_change_cbk) {
function ti_change(e) {
this.line_mc.scaleY = e.target.value;
}
$("#dom_overlay_container").on("change", "#ti", ti_change.bind(this));
this.ti_change_cbk = true;
}

whether it's 2cm depends on the screen size and resolution.

Is it true if I  wanted the change to be applied when the button is clicked the code is like this?

start.on("click", function()
{
if(!this.ti_change_cbk) {
function ti_change(e) {
this.line_mc.scaleY = e.target.value;
}
$("#dom_overlay_container").on("change", "#ti", ti_change.bind(this));
this.ti_change_cbk = true;
}

});

if you have a start object, use:

this.start.on("click"),function(){

this.line_mc.scaleY=this.ti_value;

}

if(!this.ti_change_cbk) {
function ti_change(e) {
this.ti_value= e.target.value;
}
$("#dom_overlay_container").on("change", "#ti", ti_change.bind(this));
this.ti_change_cbk = true;
}
