在跨平臺(tái)開發(fā)中，猶豫使用的是非原生開發(fā)語言，會(huì)導(dǎo)致很多不方便的地方，最近公司做一個(gè)統(tǒng)計(jì)圖表的東西，如果用原生開發(fā)的話比較容易控制圖表顯示時(shí)手機(jī)屏幕的方向，在跨平臺(tái)開發(fā)中比較麻煩，

如果用戶打開了手機(jī)屏幕自動(dòng)旋轉(zhuǎn)，有可能導(dǎo)致圖表顯示的錯(cuò)誤。
解決方案：
ichartjs designer
var evt = "onorientationchange" in window ? "orientationchange" : "resize";
window.addEventListener(evt, function() {
console.log(evt);
var width = document.documentElement.clientWidth;
var height = document.documentElement.clientHeight;
$print = $('#ichart-render');
if(width > height) {
$print.width(width);
$print.height(height);
$print.css('top', 0);
$print.css('left', 0);
$print.css('transform', 'none');
$print.css('transform-origin', '50% 50%');
//這里取得了圖表顯示控件后要對(duì)其進(jìn)行設(shè)置CSS，否則來回旋轉(zhuǎn)將導(dǎo)致布局錯(cuò)誤
var x = document.getElementById("ichart-render");
x.style.position = "absolute";
x.style.top = "20%";
} else {
$print.width(height);
$print.height(width);
$print.css('top', 0);
$print.css('left', 0);
$print.css('transform', 'none');
$print.css('transform-origin', '50% 50%');
}
}, false);
var w = document.documentElement.clientWidth;
var h = document.documentElement.clientHeight;
var diameter = Math.min(w, h);
//這里獲得了手機(jī)屏幕的寬高后，為了旋轉(zhuǎn)手機(jī)的時(shí)候?qū)е陆缑娌换靵y，需要將顯
示的圖表設(shè)置為寬高最小的正方形（取巧）
console.log(diameter);
