經navigator.userAgent 進行match updated.
function getBowser() {
if ((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1) {
alert('Opera');
} else if (navigator.userAgent.indexOf("Edg") != -1) {
alert('Edge');
} else if (navigator.userAgent.indexOf("Chrome") != -1) {
alert('Chrome');
} else if (navigator.userAgent.indexOf("Safari") != -1) {
alert('Safari');
} else if (navigator.userAgent.indexOf("Firefox") != -1) {
alert('Firefox');
} else if ((navigator.userAgent.indexOf("MSIE") != -1) || (!!document.documentMode == true)) //IF IE > 10
{
alert('IE');
} else {
alert('unknown');
}
}
下面這個更廣為流傳,但其實無法在 iOS Chrome上作出檢查 當然上面的也只會見到Safari, 因為某種瀏覽器內核的原因,但檢查錯了,總比直接停了來得好
function getExplorerInfo() {
let explorer = window.navigator.userAgent;
explorer = explorer.toLowerCase();
//ie
if (explorer.indexOf('msie') >= 0) {
let ver = explorer.match(/msie ([\d.]+)/)[1] || '';
return { name: 'IE', version: ver };
}
//firefox
else if (explorer.indexOf('firefox') >= 0) {
let ver = explorer.match(/firefox\/([\d.]+)/)[1] || '';
return { name: 'Firefox', version: ver };
}
//Chrome
else if (explorer.indexOf('chrome') >= 0) {
let ver = explorer.match(/chrome\/([\d.]+)/)[1] || '';
return { name: 'Chrome', version: ver };
}
//Opera
else if (explorer.indexOf('opera') >= 0) {
let ver = explorer.match(/opera.([\d.]+)/)[1] || '';
return { name: 'Opera', version: ver };
}
//Safari
else if (explorer.indexOf('safari') >= 0) {
let ver = explorer.match(/version\/([\d.]+)/)[1] || '';
return { name: 'Safari', version: ver };
}
if (explorer.indexOf('edge') >= 0) {
let ver = explorer.match(/edge\/([\d.]+)/)[1] || '';
return { name: 'edge', version: ver };
}
return { name: '', version: '' };
}
