我已经看到了如何检测桌面浏览器缩放级别的多个示例,但我似乎无法找到如何为Android 2.2浏览器执行此操作。
此示例适用于桌面中的chrome:
function detectZoom() {
var screenCssPixelRatio = (window.outerWidth - 8) / window.innerWidth;
zoomLevel = 0;
if (screenCssPixelRatio >= .46 && screenCssPixelRatio <= .54) {
zoomLevel = "-4";
} else if (screenCssPixelRatio <= .64) {
zoomLevel = "-3";
} else if (screenCssPixelRatio <= .76) {
zoomLevel = "-2";
} else if (screenCssPixelRatio <= .92) {
zoomLevel = "-1";
} else if (screenCssPixelRatio <= 1.10) {
zoomLevel = "0";
} else if (screenCssPixelRatio <= 1.32) {
zoomLevel = "1";
} else if (screenCssPixelRatio <= 1.58) {
zoomLevel = "2";
} else if (screenCssPixelRatio <= 1.90) {
zoomLevel = "3";
} else if (screenCssPixelRatio <= 2.28) {
zoomLevel = "4";
} else if (screenCssPixelRatio <= 2.70) {
zoomLevel = "5";
} else {
zoomLevel = "0";
}
return zoomLevel;
}
任何帮助表示感谢。
