通过自定义协议使的浏览器可以调起客户端本地程序的方法：
1.新建protocolcheck.js文件(内容是github里一个大神写的)
文件引入：<script src="protocolcheck.js"></script>
(function(f){
if(typeof exports==="object"&&typeof module!=="undefined"){
module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)
}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){
g=global
}else if(typeof self!=="undefined"){
g=self
}else{
g=this
}
g.protocolCheck = f()
}
}
)
(function(){
var define,module,exports;
return (function e(t,n,r){
function s(o,u){
if(!n[o]){if(!t[o]){
var a=typeof require=="function"&&require;
if(!u&&a)return a(o,!0);
if(i)return i(o,!0);
var f=new Error("Cannot find module '"+o+"'");
throw f.code="MODULE_NOT_FOUND",f
}
var l=n[o]={
exports:{}};
t[o][0].call(l.exports,function(e){
var n=t[o][1][e];
return s(n?n:e)},l,l.exports,e,t,n,r)
}
return n[o].exports
}
var i=typeof require=="function"&&require;
for(var o=0;o<r.length;o++)s(r[o]);
return s
})
({1:[function(require,module,exports){
function _registerEvent(target, eventType, cb) {
if (target.addEventListener) {
target.addEventListener(eventType, cb);
return {
remove: function () {
target.removeEventListener(eventType, cb);
}
};
} else {
target.attachEvent(eventType, cb);
return {
remove: function () {
target.detachEvent(eventType, cb);
}
};
}
}
function _createHiddenIframe(target, uri) {
var iframe = document.createElement("iframe");
iframe.src = uri;
iframe.id = "hiddenIframe";
iframe.style.display = "none";
target.appendChild(iframe);
return iframe;
}
function openUriWithHiddenFrame(uri, failCb, successCb) {
var timeout = setTimeout(function () {
failCb();
handler.remove();
}, 1000);
var iframe = document.querySelector("#hiddenIframe");
if (!iframe) {
iframe = _createHiddenIframe(document.body, "about:blank");
}
var handler = _registerEvent(window, "blur", onBlur);
function onBlur() {
clearTimeout(timeout);
handler.remove();
successCb();
}
iframe.contentWindow.location.href = uri;
}
function openUriWithTimeoutHack(uri, failCb, successCb) {
var timeout = setTimeout(function () {
failCb();
handler.remove();
}, 1000);
//handle page running in an iframe (blur must be registered with top level window)
var target = window;
while (target != target.parent) {
target = target.parent;
}
var handler = _registerEvent(target, "blur", onBlur);
function onBlur() {
clearTimeout(timeout);
handler.remove();
successCb();
}
window.location = uri;
}
function openUriUsingFirefox(uri, failCb, successCb) {
var iframe = document.querySelector("#hiddenIframe");
if (!iframe) {
iframe = _createHiddenIframe(document.body, "about:blank");
}
try {
iframe.contentWindow.location.href = uri;
successCb();
} catch (e) {
if (e.name == "NS_ERROR_UNKNOWN_PROTOCOL") {
failCb();
}
}
}
function openUriUsingIEInOlderWindows(uri, failCb, successCb) {
if (getInternetExplorerVersion() === 10) {
openUriUsingIE10InWindows7(uri, failCb, successCb);
} else if (getInternetExplorerVersion() === 9 || getInternetExplorerVersion() === 11) {
openUriWithHiddenFrame(uri, failCb, successCb);
} else {
openUriInNewWindowHack(uri, failCb, successCb);
}
}
function openUriUsingIE10InWindows7(uri, failCb, successCb) {
var timeout = setTimeout(failCb, 1000);
window.addEventListener("blur", function () {
clearTimeout(timeout);
successCb();
});
var iframe = document.querySelector("#hiddenIframe");
if (!iframe) {
iframe = _createHiddenIframe(document.body, "about:blank");
}
try {
iframe.contentWindow.location.href = uri;
} catch (e) {
failCb();
clearTimeout(timeout);
}
}
function openUriInNewWindowHack(uri, failCb, successCb) {
var myWindow = window.open('', '', 'width=0,height=0');
myWindow.document.write("<iframe src='" + uri + "'></iframe>");
setTimeout(function () {
try {
myWindow.location.href;
myWindow.setTimeout("window.close()", 1000);
successCb();
} catch (e) {
myWindow.close();
failCb();
}
}, 1000);
}
function openUriWithMsLaunchUri(uri, failCb, successCb) {
navigator.msLaunchUri(uri,
successCb,
failCb
);
}
function checkBrowser() {
var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var ua = navigator.userAgent.toLowerCase();
return {
isOpera : isOpera,
isFirefox : typeof InstallTrigger !== 'undefined',
isSafari : (~ua.indexOf('safari') && !~ua.indexOf('chrome')) || Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0,
isIOS : /iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream,
isChrome : !!window.chrome && !isOpera,
isIE : /*@cc_on!@*/false || !!document.documentMode // At least IE6
}
}
function getInternetExplorerVersion() {
var rv = -1;
if (navigator.appName === "Microsoft Internet Explorer") {
var ua = navigator.userAgent;
var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
if (re.exec(ua) != null)
rv = parseFloat(RegExp.$1);
}
else if (navigator.appName === "Netscape") {
var ua = navigator.userAgent;
var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
if (re.exec(ua) != null) {
rv = parseFloat(RegExp.$1);
}
}
return rv;
}
module.exports = function(uri, failCb, successCb, unsupportedCb) {
function failCallback() {
failCb && failCb();
}
function successCallback() {
successCb && successCb();
}
if (navigator.msLaunchUri) { //for IE and Edge in Win 8 and Win 10
openUriWithMsLaunchUri(uri, failCb, successCb);
} else {
var browser = checkBrowser();
if (browser.isFirefox) {
openUriUsingFirefox(uri, failCallback, successCallback);
} else if (browser.isChrome || browser.isIOS) {
openUriWithTimeoutHack(uri, failCallback, successCallback);
} else if (browser.isIE) {
openUriUsingIEInOlderWindows(uri, failCallback, successCallback);
} else if (browser.isSafari) {
openUriWithHiddenFrame(uri, failCallback, successCallback);
} else {
unsupportedCb();
//not supported, implement please
}
}
}
},{}]},{},[1])(1)
});
2.新建example.js文件(可以引入，或者直接写在html文件里)
$(function () {
$("div[href]").click(function (event) {
window.protocolCheck($(this).attr("href"),
function () {
alert("协议未注册");
});
event.preventDefault ? event.preventDefault() : event.returnValue = false;
});
});
3.实例：
ff协议是自定义通用URL协议实现在浏览器中打开本机任意程序文中示例的协议。你可以替换成任意存在的协议。
引入example.js
<!DOCTYPE html>
<html>
<head lang="zh">
<meta charset="UTF-8">
<title>自定义协议探测</title>
</head>
<body>
<h1>Click one of these labels:</h1>
<div href="unexists:randomstuff">一个不存在的协议</div>
<div href="ff://C:/Windows/System32/notepad.exe">一个存在的协议</div>
<script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
<script src="protocolcheck.js"></script>
<script src="example.js"></script>
</body>
</html>
写入example.js
<!DOCTYPE html>
<html>
<head lang="zh">
<meta charset="UTF-8">
<title>自定义协议探测</title>
</head>
<body>
<h1>Click one of these labels:</h1>
<div href="unexists:randomstuff">一个不存在的协议</div>
<div href="ff://C:/Windows/System32/notepad.exe">一个存在的协议</div>
<script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
<script src="protocolcheck.js"></script>
<!-- <script src="example.js"></script> -->
</body>
</html>
<script>
$("div[href]").click(function (event) {
window.protocolCheck($(this).attr("href"),
function () {
alert("协议未注册");
});
event.preventDefault ? event.preventDefault() : event.returnValue = false;
});
</script>
