我正在尝试根据浏览器支持在图像上显示过滤器。
如何使用javascript检查浏览器是否支持特定的CSS属性,如filter和--webkit-filter?
我正在使用以下功能,但它无效
isCSSStyleSupported: function(prop, value) {
// If no value is supplied, use "inherit"
value = arguments.length === 2 ? value : 'inherit';
// Try the native standard method first
if ('CSS' in window && 'supports' in window.CSS) {
return window.CSS.supports(prop, value);
}
// Check Opera's native method
if('supportsCSS' in window){
return window.supportsCSS(prop, value);
}
// Convert to camel-case for DOM interactions
var camel = prop.replace(/-([a-z]|[0-9])/ig, function(all, letter) {
return (letter + '').toUpperCase();
});
// Check if the property is supported
var support = (camel in el.style);
// Create test element
var el = document.createElement('div');
// Assign the property and value to invoke
// the CSS interpreter
el.style.cssText = prop + ':' + value;
// Ensure both the property and value are
// supported and return
return support && (el.style[camel] !== '');
},
