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

In a web-page I've got a search field. I've added a "clear" button so that users can clear the search field and start again. As a convenience, I focus the search field's text box and the cursor does appear in the box. However the soft k开发者_StackOverflow社区eyboard does not seem to show up on android devices that use the default browser. In iOS and Opera Mobile it works as I'd expect.

Is there an additional method I can call that will cause the keyboard to show on Android's browser so the user can start typing right away?

function clear_search() {
    if($('#searchinput').val()) {
        $('#searchinput').val('');
    }
    $('#searchinput').focus();
}

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();
}

I am not 100% sure but I think it can`t be done (at least until android 2.2) from javascript. If you are using phonegap you can use this here: https://github.com/phonegap/phonegap/wiki/How-to-show-and-hide-soft-keyboard-in-Android
