Prevent document reflow/browser resize when android keyboard opens

Question

This is for a HTML5/Javascript WebApp, not a native android app.

How do I prevent the browser/the DOM from resizing my content (which is responsive, mostly vw/vh for siz

Answer 1

Ok , this is fix for html5 (browser) app .

var isKeyboardOpen = false;

// Override onresize event if you have it already just insert code 
// also you can check id of element or any other parameters
if (document.activeElement.tagName == "INPUT" ||
    document.activeElement.tagName == "input") {

    // regular onresize
}
else {
    // avoid resize
}

// To check is it keyboard open use this code 

window.addEventListener('native.showkeyboard', keyboardShowHandler);

window.addEventListener('native.hidekeyboard', keyboardHideHandler);

function keyboardShowHandler(e){
    isKeyboardOpen = true; //always know status
}

function keyboardHideHandler(e){
    isKeyboardOpen = false;
}

Initially try to prevent by setting the flag :

var object_ = document.getElementById("IwillOpenKeyboardOnMobile");
object_.addEventListener("focus", ONFOCUSELEMENT);

function ONFOCUSELEMENT() {
    isKeyboardOpen = true; 
}

// opposite event is blur
