$(document).ready(function() {
// Detect ios 11_x_x affected
// NEED TO BE UPDATED if new versions are affected
var ua = navigator.userAgent,
iOS = /iPad|iPhone|iPod/.test(ua),
iOS11 = /OS 11_0|OS 11_1|OS 11_2/.test(ua);
// ios 11 bug caret position
if ( iOS && iOS11 ) {
// Add CSS class to body
$("body").addClass("iosBugFixCaret");
}
});
对于CSS
/* Apply CSS to iOS affected versions only */
body.iosBugFixCaret.modal-open { position: fixed; width: 100%; }
**版本2 - 仅限选定的模态**
我修改了函数,仅针对具有类的选定模态触发 .inputModal
只有具有输入的模态才会受到影响,以避免滚动到顶部.
对于Javascript/jQuery
$(document).ready(function() {
// Detect ios 11_x_x affected
// NEED TO BE UPDATED if new versions are affected
(function iOS_CaretBug() {
var ua = navigator.userAgent,
scrollTopPosition,
iOS = /iPad|iPhone|iPod/.test(ua),
iOS11 = /OS 11_0|OS 11_1|OS 11_2/.test(ua);
// ios 11 bug caret position
if ( iOS && iOS11 ) {
$(document.body).on('show.bs.modal', function(e) {
if ( $(e.target).hasClass('inputModal') ) {
// Get scroll position before moving top
scrollTopPosition = $(document).scrollTop();
// Add CSS to body "position: fixed"
$("body").addClass("iosBugFixCaret");
}
});
$(document.body).on('hide.bs.modal', function(e) {
if ( $(e.target).hasClass('inputModal') ) {
// Remove CSS to body "position: fixed"
$("body").removeClass("iosBugFixCaret");
//Go back to initial position in document
$(document).scrollTop(scrollTopPosition);
}
});
}
})();
});
对于CSS
/* Apply CSS to iOS affected versions only */
body.iosBugFixCaret.modal-open { position: fixed; width: 100%; }
