I was working in IOS mobile app which is using jQuery mobile and Phonegap and get issue that header and footer moving when entering text in a text box or text area.
Here, I am going to explain about to stop moved header and footer when open a keyboard and enter a text in search box IOS.
Let’s see solution for moving header and footer in IOS version.
id_textboc_addcourse is a id of textbox and .footer is a class name of footer and .topbar is Header class name.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | if (parseFloat(window.device.version) >= 5.0) { if ($(this).attr('readonly') === undefined) { $('.footer').show(); $(document).scrollTop($('.footer').position().top); $('.topbar').css('position', 'absolute'); } } }); $(document).on('blur', 'input, select, textarea', function() { if (parseFloat(window.device.version) >= 5.0) { if ($(this).attr('readonly') === undefined) { $('.footer').show(); $('.footer').css('position', 'fixed'); $('.topbar').css('position', 'fixed'); } } }); |
I am going to explain here a two ways to solve this issue，but they have a little shortcoming.
Way 1: Here in this way,shortcoming is Editing text is a bit slow for ‘position’, ‘absolute’. But let’s understand code written below:
1 2 3 4 5 6 7 8 9 10 11 12 | $(document).on('focus', 'input,textArea', function() { $('div[data-role="header"]').css('position', 'absolute'); $('div[data-role="footer"]').css('position', 'absolute'); $(document).scrollTop(document.body.scrollHeight); $(document).trigger("refresh"); }) .on('blur', 'input,textArea', function() { $('div[data-role="header"]').css('position', 'fixed'); $('div[data-role="footer"]').css('position', 'fixed'); }); |
Lets understand the next code which is explained below:
Way 2: shortcoming is page margins top and bottom.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | $(document).on('focus', 'input,textArea', function() { $('div[data-role="header"]').css('position', 'relative'); $('div[data-role="footer"]').css('position', 'relative'); $(document).scrollTop(document.body.scrollHeight); $(document).trigger("refresh"); }) .on('blur', 'input,textArea', function() { $('div[data-role="header"]').css('position', 'fixed'); $('div[data-role="footer"]').css('position', 'fixed'); }); $(document).on('focus', 'input, textarea', function() { $('div[data-role="header"]').css('position', 'absolute'); $.mobile.silentScroll($('input:focus').offset().top - 100); }); $(document).on('blur', 'input, textarea', function() { $('div[data-role="header"]').css('position', 'fixed'); }); |
