Showing Android's soft keyboard when a field is .focus()'d using javascript

this question is similar to How to focus an input field on Android browser through javascript or jquery

Anyway, as you already have a click event to work with, this should sort you out:

$(document).ready(function() {
    $('#field').click(function(e){ $(this).focus(); });

    $('#button').click(function(e) {
        $('#field').trigger('click');
    });
})     

Of course you DO need a click event triggering this. Just focussing without an event doesnt seem to work. The above works for me on the standard browser on android 4 and shows the soft keyboard.

click() on its own is not enough. You need to focus() then click(). Beware of endless loops if your script is triggered by an onclick() on a containing element. The script below is working for me on Chrome for android 58 and Safari mobile 602.1.

var target = document.getElementsByTagName("input")[0];

if (event.target != target) {
    target.focus();
    target.click();
}
