原标题,但邮寄太长:
“ASP.NET MVC 4,Razor,JQuery,JQueryMobile,Mobiscroll问题 – orientationchange和访问地址栏崩溃了一些移动浏览器.改变滚动条的宽度和高度在某些手机上不起作用.”
崩溃问题发生在Android 2.1上.
它不会发生在iPhone,HTC EVO 4G LTE或其他HTC上.
更改滚动条宽度和高度不适用于HTC.如果我更改为横向,则滚动条的大小应与纵向相同.如果我将它改回肖像,那么卷轴就是它应该在横向上的尺寸.
这是JQuery / Mobiscroll代码:
function createDatePicker(selector){
if($("#input_date_1").scroller('isdisabled') != 'undefined'){
var scrollWidth = ($("div[id='main_content']").width()) / 4;
var scrollHeight = scrollWidth / 2.5;
$("#input_" + selector).scroller({
preset: 'date',
minDate: new Date(2000, 0, 1),
maxDate: new Date(2020, 11, 31),
theme: 'android',
display: 'inline',
mode: 'scroller',
dateOrder: 'mmddyy',
width: scrollWidth,
height: scrollHeight,
onChange: function (valueText, inst) {
var lbl = $("#lbl_" + selector);
var date = $("#input_" + selector).scroller('getDate');
lbl.text(date.toDateString());
}
});
}
function setDatePickerWidthAndHeight(){
var scrollWidth = ($("div[id='main_content']").width()) / 4;
var scrollHeight = scrollWidth / 2.5;
var selectorBase1 = "date_1";
$("#input_" + selectorBase1).eq(0).scroller('option', 'width', scrollWidth);
$("#input_" + selectorBase1).eq(0).scroller('option', 'height', scrollHeight);
}
$(function () {
createDatePicker('date_1');
$(window).bind('orientationchange', function (event) {
setTimeout(setDatePickerWidthAndHeight(),100);
});
});
我将这些脚本包含在@section scripts {}中,这些脚本在页面底部呈现(不确定是否相关).
任何帮助,将不胜感激.
解决方法:
事实证明,问题是旧的Android手机不像上面写的那样喜欢调整大小事件….而且新手机不喜欢orientationchange事件.此链接的代码使一切工作完美:
http://paulirish.com/2009/throttled-smartresize-jquery-event-handler/
以下是我如何使用它:
//
// usage:
//$(window).smartresize(function () {
// // code that takes it easy...
//});
//http://paulirish.com/2009/throttled-smartresize-jquery-event-handler/
(function ($, sr) {
// debouncing function from John Hann
// http://unscriptable.com/index.PHP/2009/03/20/debouncing-javascript-methods/
var debounce = function (func, threshold, execAsap) {
var timeout;
return function debounced() {
var obj = this, args = arguments;
function delayed() {
if (!execAsap)
func.apply(obj, args);
timeout = null;
};
if (timeout)
clearTimeout(timeout);
else if (execAsap)
func.apply(obj, args);
timeout = setTimeout(delayed, threshold || 100);
};
}
// smartresize
jQuery.fn[sr] = function (fn, threshold, execAsap) { return fn ? this.bind('resize', debounce(fn, threshold, execAsap)) : this.trigger(sr); };
})(jQuery, 'smartresize');
$(function () {
createDatePicker('date_1');
$(window).smartresize(function () {
setDatePickerWidthAndHeight();
}, 200);
});

谢谢!
