我在想,如果以下的语法 评估,我认为它做的:
Cluster.prototype.test_json_availability = function() {
return Modernizr.addTest( test_json , function() {
return (typeof $.browser.msie !== undefined && $.browser.msie === true && $.browser.version < 7 && typeof window.JSON === undefined ) ? false : true;
});
};
假设我确实使用MS浏览器,这意味着它会恢复真实?还是我做错了?
org/wiki/de_Morgan%27s_laws" rel=“nofollow”>De Morganss laws :
function test_json() {
return typeof $.browser.msie === undefined
|| $.browser.msie !== true
|| $.browser.version > 6
|| typeof window.JSON !== undefined ;
}
这将大大简化状况,你可以找到问题答案。
